Producing highly efficient LEDs based on 2D perovskite films

Energy-efficient light-emitting diodes (LEDs) have been used in our everyday life for many decades. But the quest for better LEDs, offering both lower costs and brighter colours, has recently drawn scientists to a material called perovskite. A recent joint-research project co-led by the scientist from
City University of Hong Kong (CityU) has now developed a 2D perovskite material for the most efficient LEDs.
From household lighting to mobile phone displays, from pinpoint lighting needed for endoscopy procedures to light source to grow vegetables in Space, LEDs are everywhere. Yet current high-quality LEDs still need to be processed at high temperatures and using elaborated deposition technologies which make their production cost expensive. ....

In comparison to the conventional light microscopy, cryo electron tomography is a powerful tool that offers much deeper insights into the cell structure by unveiling high-resolution 3D views of biological samples such as large macromolecules. In the first step, samples are immobilized by high-speed freezing at extreme temperatures under ?150 °C. These cryogenic conditions make it possible to study samples without chemical fixation or dehydration, thereby preventing distortion or disruption of biological structures of the sample. However, the preparation and the handling of the samples are very complex, since the formation of crystalline ice can compromise the structural integrity of the specimen. ....

An electrically charged glass display smoothly transitions between a spectrum of colors

Credit: Jilin University
Scientists have developed a see-through glass display with a high white light contrast ratio that smoothly transitions between a broad spectrum of colors when electrically charged. The technology, from researchers at Jilin University in Changchun, China, overcomes limitations of existing electrochromic devices by harnessing interactions between metal ions and ligands, opening the door for numerous future applications. The work appears March 10 in the journal
Chem.
We believe that the method behind this see-through, non-emissive display may accelerate the development of transparent, eye-friendly displays with improved readability for bright working conditions, says Yu-Mo Zhang, an associate professor of chemistry at Jilin University and an author on the study. As an inevitable display technology in the near future, non-emissive see-through displays will be ubiquitous and irreplaceable as a part of the Internet of Things, in which physical ob ....

OFC 2021 Conference and Exhibition to host global visionaries in an interactive, all-virtual format

E-Mail
WASHINGTON - The premier event in telecom and data center optics the 2021 Optical Fiber Communication Conference and Exhibition (OFC) today announced it will convene in an interactive, all-virtual format, 06 - 11 June 2021. Considered the hub of the industry, OFC represents the entire ecosystem from research to marketplace. This format, which includes technical sessions and a virtual exhibition featuring industry-focused programs, will expand engagement with the conference s global audience through live and on-demand content.
This has been a challenging year for all of us, but as the international event for the global optical communications community to move the field forward, we must ensure that the groundbreaking content is accessible to a broad audience, said Po Dong, OFC General Chair, II-VI Incorporated, USA. OFC draws executives, technical experts, academia, media and analysts from all over the world, and this approach will allow our attendees and speaker ....
