MHI: Advanced light water reactor “SRZ-1200”

TOKYO, Sep 29, 2022 - (JCN Newswire via SEAPRWire.com) - Mitsubishi Heavy Industries, Ltd. (MHI) in collaboration with four Japanese PWR utilities*, has developed the conceptual design of an advanced light water reactor "SRZ-1200". This reactor has additional safety features when compared to conventional pressurized light water reactors. It is in the intention of MHI to take the SRZ-1200 conceptual design and proceed with basic design efforts. These efforts will ensure new innovative nuclear technologies are available toward a stable energy supply for Japan.Advanced light water reactor "SRZ-1200"The SRZ-1200 is a 1,200MWe class advanced light water reactor designed based on enhanced Japanese regulatory safety standards which incorporates lessons learned from the Fukushima Daiichi accident. Development of the SRZ-1200 is in progress which will ensure the regulatory requirements of "strengthening safety equipment" and "resistance to natural disaster and security against terrorism and unforeseen event" are fulfilled. The cumulation of this development will ensure safety and reliability of the SRZ-1200.Relative to new safety mechanisms, even though the SRZ-1200 accounts for global lesson learned, low-probability postulated events are still accounted for in the design to ensure plant and public safety. These safety mechanisms include, but are not limited to, an advanced accumulator design, and systems which effectively reduce the probability of radioactivity release in the event of a postulated accident. Efforts of this nature and the resultant SRZ-1200 design features will limit any impact to the public and plant site.Furthermore, the SRZ-1200 design is intended to enhance operational flexibility which will effectively allow for improved electrical power delivery alongside variable electric power sources such as renewables. The ability to adapt the SRZ-1200 for hydrogen production will also be studied to ensure that all potential uses of energy generated from this plant are efficiently and proactively applied for all of societal needs.MHI has been involved in the construction and maintenance of all of the 24 PWRs in Japan and has led the efforts to restart and ensure the safe operation of the existing nuclear power plants. These efforts will continue as we bring the SRZ-1200 to market as early as possible to realize a carbon-neutral society for Japan.The name of SRZ has the following meaning:S: supreme safety, sustainabilityR: resilient light water reactorZ: ultimate type (Z) contributing to society by Zero Carbon emission.(In Japan, "Z" also has a meaning of "ultimate type")1200: represents the electrical power output of 1200MWe classTaking into account the Fukushima Daiichi accident, MHI Group strives to continuously enhance safety through the restart of existing nuclear power plants as well as the safe and stable operation upon restart. This is part of our contribution to society and we intend to continue this contribution through the development of advanced light water reactors which achieve the world's highest level of safety.*Four PWR utilities: Hokkaido Electric Power Co., Inc., The Kansai Electric Power Co., Inc., Shikoku Electric Power Co., Inc., and Kyushu Electric Power Co., Inc.About MHI GroupMitsubishi Heavy Industries (MHI) Group is one of the world's leading industrial groups, spanning energy, smart infrastructure, industrial machinery, aerospace and defense.

Windows gain competitive edge over global warming

TSUKUBA, Japan, Sep 1, 2022 - (ACN Newswire via SEAPRWire.com) - A French-Japanese research collaboration has fabricated metal nanocomposite coatings that improve the insulating properties of window glasses. The new coating prevents a significant portion of near-infrared (NIR) and ultraviolet rays (UV) from passing through, while at the same time admitting visible light. The findings were reported in the journal Science and Technology of Advanced Materials.The nanoclusters are dispersed in a PVP matrix that is then coated on ITO glass to block NIR and UV rays while letting visible light pass through."Although the fabrication of a commercial products is still a long way ahead, our work demonstrated a significant improvement in UV and NIR blocking properties compared to previous research," says solid-state chemist Fabien Grasset, research director at the French National Centre for Scientific Research (CNRS)."Buildings account for a large part of global energy consumption," explains Grasset, "with a large amount of the annual energy consumption of a standard building going to cooling and/or heating systems to maintain indoor temperatures at comfortable levels." Scientists are looking for ways to develop window glass coatings that can block the entry of NIR radiation so that buildings, and even cars, can consume less energy to keep it cool inside. However, this needs to be done in a way that still allows visible light to enter. Ideally, harmful UV rays would also be blocked.To this end, the international French-Japanese research collaboration fabricated and analysed the performance of nanocomposites based on niobium-tantalum cluster compounds containing chloride or bromide ions.They found that chloride-based nanoclusters provided the best performance in terms of blocking NIR and UV rays and allowing the passage of visible light. NIR and UV blocking by the nanoclusters depended on their concentration, dispersion and oxidation state. By tuning these parameters, the team was able to improve the nanocluster performance.The nanoclusters were dispersed into a polyvinylpyrrolidone (PVP) matrix that was then coated onto indium-tin-oxide (ITO) glass. The combination increased the transmittance of visible light while reducing that of NIR and UV rays, relative to previous research. "These are very promising coating materials that block the most troublesome NIR wavelengths," says Grasset."We have a long history of Japanese-French collaboration," he continues. "We were already convinced that we are stronger working together by mixing our different cultures and ways of thinking. The international LINK project has reinforced this belief. We will continue to do our best to make further progress towards finding solutions for the global warming problem."Further informationFabien GrassetFrench National Centre for Scientific Research (CNRS)Email: fabien.grasset@cnrs.frResearch paper: https://www.tandfonline.com/doi/full/10.1080/14686996.2022.2105659About Science and Technology of Advanced Materials (STAM)Open access journal STAM publishes outstanding research articles across all aspects of materials science, including functional and structural materials, theoretical analyses, and properties of materials. https://www.tandfonline.com/STAMFor more information on STAM, contactDr. Mikiko TanifujiSTAM Publishing DirectorEmail: TANIFUJI.Mikiko@nims.go.jpPress release distributed by Asia Research News for Science and Technology of Advanced Materials.

Football: Arteta sees light at the end of the tunnel for Arsenal

LONDON (AFP) - Arsenal manager Mikel Arteta said he sees a bright future for the club despite suffering their worst start to a season for 67 years. The Gunners climbed off the bottom of the Premier League table with their first goal and first points of the campaign by beating Norwich 1-0 last weekend. However, Arteta's position is still under scrutiny ahead of Saturday's trip to Burnley after spending £150 million (S$270 million) on new players during the transfer window. The Spaniard claimed after beating Norwich he had enjoyed the "best 10 days of his career in this industry" during an international break when his side were rock bottom of the table. And Arteta was equally optimistic on where Arsenal are headed with all six of his summer signings aged 23 or under. "I'm telling you I'm very positive most of the time. I've seen the light and I can see bright lights," he said at his pre-match press conference on Thursday. "There can be bumps in the road within that light, but I can see a lot of light." Arteta is also hopeful the criticism his squad suffered after defeats to Brentford, Chelsea and Manchester City will only serve to make them stronger. "It's tough because it hurts, because you want to see something different. But what you want is not always what happens," he added. "Things happen for a reason and maybe what is happening had to happen and it's going to be really good for the club and really good for myself and everybody experiencing that situation. We have to believe that."

Dye-based device sees the invisible

Tsukuba, Japan, Apr 16, 2021 - (ACN Newswire via SEAPRWire.com) - Scientists in Europe have designed an organic dye-based device that can see light waves in the shortwave infrared (SWIR) range. The device is easy to make using cheap materials, and is stable at high temperatures. The findings, published in the journal Science and Technology of Advanced Materials, could lead to more widespread use of inexpensive consumer SWIR imaging and sensing devices.In the upconversion device, shortwave infrared (SWIR) light with wavelengths beyond 1,000 nm is absorbed by the squaraine dye in the photodetector (PD), producing electrical charges. Charges flow into the organic light-emitting diode (OLED), where they recombine under the emission of visible light. This way, SWIR light, which cannot be detected by the human eye, is converted into visible light.The human eye can only detect a very narrow segment of the electromagnetic spectrum, from around 400 to 700 nanometers. The SWIR region, on the other hand, extends from 1,000 to 2,500 nanometers. Specially designed cameras can take images of objects that reflect waves in the SWIR region. They are used for improving night vision, in airborne remote sensing, and deep tissue imaging. The cameras also help assess the composition and quality of silicon wafers, building structures and even food produce."These cameras are typically difficult to manufacture and are quite expensive, as they are made of inorganic semiconductor photodiode arrays interconnected with read-out integrated circuitry," says Roland Hany of the Swiss Federal Laboratories for Materials Science and Technology.Hany worked with colleagues in Switzerland and Italy to design an organic dye-based 'SWIR upconversion device' that efficiently converts shortwave infrared light to visible light.The device uses organic (materials made with carbon) components: a squaraine dye-coated flexible substrate combined with a fluorescent organic light-emitting diode (OLED). When the dye absorbs SWIR waves, an electric current is generated and directly converted into a visible image by the OLED.The team had to play with the molecular composition of several squaraine dyes to get them to absorb specific wavelengths. Ultimately, they synthesized squaraine dyes that absorb SWIR light beyond 1,200 nanometers and remained stable up to 200 degrees Celsius. The finished dye-based device performed stably for several weeks under normal laboratory conditions."All-organic upconverters could lead to applications that can't be realized with current technology. For example, invisible night vision devices can be directly integrated into car windscreens without affecting the visual field," explains Hany.The team is now working on shifting the dye's absorption further into the SWIR range. They are also using machine learning techniques to find new dye molecules capable of sensing SWIR waves. Finally, the team aims to improve device stability and sensitivity.Further informationRoland HanyEmpa, Swiss Federal Laboratories for Materials Science and TechnologyEmail: roland.hany@empa.chAbout Science and Technology of Advanced Materials JournalOpen access journal STAM publishes outstanding research articles across all aspects of materials science, including functional and structural materials, theoretical analyses, and properties of materials.Dr. Yoshikazu ShinoharaSTAM Publishing DirectorEmail: SHINOHARA.Yoshikazu@nims.go.jpPress release distributed by ResearchSEA for Science and Technology of Advanced Materials.

Materials coloured like a peacock

Tsukuba, Japan, Jan 26, 2021 - (ACN Newswire) - Melanin-like compounds can be precisely designed and arranged to colour materials using a mechanism similar to that found in a peacock's feathers. Chemist Michinari Kohri of Chiba University in Japan reviewed the latest research on these 'melanin-mimetic materials' and their potential applications for the journal Science and Technology of Advanced Materials.Scientists are developing materials inspired by the structural colours in a peacock's feathers. (Credit: Takashi Tsujino)Melanin and melanin-like compounds absorb some of the light that is scattered from the microstructures within materials. Scientists are finding ways to control this phenomenon to give a variety of iridescent and non-iridescent colours. (Credit: Michinari Kohri)Melanin is a dark pigment that gives hair and skin its colour. It is also essential for the bright colours we see in some organisms. When light interacts with the structures of feathers, wings and shells of many organisms, like peacocks, butterflies and jewel beetles, it is scattered, appearing white. But when melanin is interspersed within these structures, some of the scattered light is absorbed, producing various colours. Scientists are looking for ways to mimic these so-called 'structural colour' changes of living organisms in synthetic materials."Vivid structural colours can be obtained by constructing microstructures containing a light-absorbing black material made of natural or artificial melanin," says Kohri. "Research in this area is progressing rapidly worldwide."A leading contender is a compound called polydopamine. It is made of a material naturally found in the body, so it is biocompatible. It is also dark, so it absorbs light like melanin. Scientists found they could control polydopamine's iridescence - how much the colour changes as the angle of light hitting it shifts, similar to a peacock's feather. They achieved this by altering the particle size or by adding compounds that react to a magnetic field.Scientists are also investigating particles formed of a polystyrene core and a polydopamine shell. Changing the diameter of the inner core, for example, leads to different colours. Making the polydopamine shell thicker causes the particles to be less closely packed, leading to non-iridescent structural colour, which remains the same regardless of the light angle.Scientists have also toyed with controlling colour and angle-dependence by changing the shapes of polystyrene/polydopamine particles, making them hollow on the inside, and adding multiple coatings to the external shell.Polydopamine particles are showing potential for a variety of applications. For example, they can be used as inks to dye fabrics or in cosmetics. They could help prove a product is real versus counterfeit by shifting colour with strong light, wetting, or temperature changes. Finally, scientists have found that adding these particles to rubber causes it to change colour when stretched or relaxed, which could be useful for sensing local stress and strain in bridges.Further informationMichinari Kohri Chiba UniversityEmail: kohri@faculty.chiba-u.jpAbout Science and Technology of Advanced Materials JournalOpen access journal STAM publishes outstanding research articles across all aspects of materials science, including functional and structural materials, theoretical analyses, and properties of materials.Chikashi NishimuraSTAM Publishing DirectorNISHIMURA.Chikashi@nims.go.jpPress release distributed by ResearchSEA for Science and Technology of Advanced Materials.

WIMI’s Dr. Guo Songrui: Holographic technology and light fields

BEIJING, Oct 19, 2020 - (ACN Newswire) - Holography comes from the Latin vocabulary, and its meaning is: all, compound. According to the current common knowledge in mainstream technology filed, holography specifically refers to "holographic technology", which is a technology for reproducing diffracted light emitted by objects. Holographic technology uses the principle of interference to record the light wave messages of the object, and uses the principle of diffraction to reproduce the light wave messages of the object, helping users to store all the light information of the object. Thus, the observer can observe the different positions of the object in all directions, and the stored light information records all the light distribution in the three-dimensional space. Therefore, holographic technology is also a kind of optical storage and reproduction technology.The earliest holographic technology was discovered by Denise Gabor (1900-1979), a Hungarian physicist, who won the Nobel Prize in Physics in 1971. However, this technology was first used in electron microscopes to record and display electronic holograms. The earliest use in the field of optics was after the invention of laser technology in 1960.The holographic recording is different from ordinary photography. An ordinary camera only records the intensity of the object's light field. The hologram records the intensity of the reference light and the object light after interference. When it needs to be reproduced, it is only necessary to use the reference light to show the amplitude of the object light that fully characterizes the object information.The hologram production process uses a laser. The laser beam is strictly split 1:1 by a beam splitter. One beam of light shines on the surface of the object to be photographed, and the other beam directly shines on the photosensitive film (holographic dry plate). Moreover, this light is also called the reference beam. When the object beam is reflected by the object, its reflected beam is also irradiated on the film, completing the hologram shooting process.There are several major characteristics of holograms: 1. Omni-directional information recording. The holographic picture records the omnidirectional and comprehensive illumination information of the object, so that the object can be observed from different angles during observation. 2. Learning the whole picture from the parts. When part of the holographic picture is damaged, the whole picture of the object can still be seen from the remaining part. 3. The amount of stored information is huge, and multiple holographic photos can be recorded hierarchically on the holographic film. Moreover, they will not interfere with each other when displaying the picture.Based on the characteristics of holograms mentioned above, the application prospects of holograms are quite broad, but it is not an easy task to collect light fields to form a hologram in the early stage of technological development. Early technical methods were either expensive, such as using the aforementioned laser to irradiate objects, or using camera arrays; or collecting information was limited and inefficient, for example, the light field acquisition systems based on a fixed turntable. After 2000, with the development of digital camera shooting technology and light field shooting technology gradually attracted the attention of researchers, the light field collection technology of the single camera came into being. Until now, the light field collection technology has truly reached the civilian level.The common light field shooting techniques are divided into two categories: integral imaging and aperture coding imaging.Integral imaging is achieved by adding a microlens array or a micromirror array in front of the sensor to realize the collection of images of the light field viewpoints in different directions. There are more well-known integral imaging devices, including the lens array lens launched by Adobe, the Pelican lens array camera on the mobile phone, the Lytro light field camera, the R series light field camera of Raytrix, and so on.The shooting based on the compressed light field is to add an optical mask between the camera lens and the sensor to achieve compression encoding of the light entering the camera aperture. The more well-known equipment is the prototype of the light field camera developed by Babacan et al. They proposed to use the method of encoding mask and programmed aperture to capture light field viewpoints in different directions, which can obtain light field with high spatial resolution.The microlens array has the advantages of low cost and small size, but its disadvantage is that the image resolution loss is serious. The coding imaging technology has the advantages of small size, no loss of resolution, but its advantages are low signal-to-noise ratio and low light field quality.From the perspective of the development of light field cameras, encoding-based light field acquisition equipment breaks the mutual restriction between angular resolution and viewpoint image resolution. The redundant information in the light field can be removed through machine learning, and the light field can be restored from a small amount of information. In the future 4K era, the advantage of not losing resolution will be the focus of this technology.In the near future, when light field acquisition equipment develops to a sufficiently high resolution, as well as has fast enough acquisition speed, and cheap, the light field data, as a kind of rich media data, is stored in a large amount of non-overlapping data that can be passed through a single point. The complete picture of data information will become a new data treasure house for data scientists to research and mine. In particular, unexpected achievements may be obtained in many fields, such as holographic recognition, holographic payment, holographic authentication, and so on.Guo Songrui:Doctor of Computer Science and Technology Engineering from Hunan University, studied mixed reality and augmented reality technology at the State Key Laboratory of Scientific Computing of the Chinese Academy of Sciences, and participated in the research and development of multiple key projects.About WIMI Hologram Cloud Inc.WiMi Hologram Cloud, Inc.
