MIT physicists and colleagues measured quantum geometry for first time, opening new avenues for understanding and manipulating electrons in materials.

Researchers have devised a novel catalyst aimed at enhancing the efficiency of reactions using contaminated municipal sewage to produce hydrogen—a green energy source.

The recent cold spell has plunged South Korean into a deep freeze, resulting in the closure of 247 national parks, the cancellation of 14 domestic flights, and the scrapping of 107 cruise ship voyages. While the cold snap brought relief by significantly reducing the prevalence of particulate matter obscuring our surroundings, a recent study indicates that, besides diminishing particulate matter, it significantly…

Aptamers, nucleic acids capable of selectively binding to viruses, proteins, ions, small molecules, and various other targets, are garnering attention in drug development as potential antibody substitutes for their thermal and chemical stability as well as their ability to inhibit specific enzymes or target proteins through three-dimensional binding.

The outbreak of the COVID pandemic in 2020 has once again shown how important reliable and rapid detection methods are to initiate effective measures to combat a pandemic. Scientists from the Chair of Materials Science and Nanotechnology at TU Dresden (TUD) have made considerable progress in the development of highly innovative solutions for the detection of viral pathogens in two studies they presented recently.

Metasurfaces are artificial materials adept at manipulating perception. With metasurfaces allowing lenses to be reduced to one 10,000th the size of conventional lenses, they are generating considerable interest as optical components allowing miniaturization of optical systems for the next generation of virtual and augmented reality as well as LiDAR.

Recently, a group of illegal counterfeiters was apprehended for producing around 400 fake luxury jewelry items using molds. They were able to create hundreds of faked luxury items simply after pouring molten metal into molds produced from the original jewelry. Similarly, in the molecular world, a template scaffold can produce an endless amount of molecular crystals of any shape or form.

During the COVID-19 pandemic last year, an incident occurred where vaccines exposed to room temperature had to be discarded. Biomedical substances, including vaccines, risk deterioration if not stored properly, so strict management is required during production and storage. In particular, exposure to light may reduce the vaccine's efficacy, so it is important to check whether it has been damaged by light exposure.

A team of researchers from the Pohang University of Science and Technology and the Korean Institute for Basic Science has demonstrated deep-ultraviolet (DUV) electroluminescence and photocurrent generation in hexagonal boron nitride, a semiconductor often called the 'white graphene.'

Ultraviolet rays find diverse applications in medical and health care, serving purposes such as disinfection, sterilization, and therapy. They are also used in the semiconductor industry for creating microcircuits and patterns.

Recently, a research team from Pohang University of Science and Technology (POSTECH) has employed metasurfaces to fabricate angle-dependent holograms with multiple functions. This technology allows holograms to display multiple images based on the observer's viewing angle. The findings were published in Nano Letters.

The ongoing COVID-19 endemic phase has brought a consistent rise in international travelers. The Credit Finance Association revealed that overseas expenditures on personal debit cards from seven credit card companies had surged by approximately 38% year on year as of the third quarter of 2023.

In order to enhance the accessibility of hydrogen-powered vehicles and establish hydrogen as a viable energy source, it's imperative to reduce the cost of hydrogen production, thereby achieving economic feasibility. To achieve this goal, maximizing the efficiency of electrolysis-hydrogen evolution, the process responsible for producing hydrogen from water, is crucial.

A Korean superconductivity academic body invalidated the research results from a team of Korean researchers claiming to have developed a room-temperature superconductor in its preliminary assessment.

M1 and M2 are activated macrophages that protect our immune system and maintain homeostasis. Interestingly, they are characterized by distinct and opposing phenotypes. M1 macrophages are known for their bactericidal and tumoricidal properties by secreting pro-inflammatory cytokines, while M2 macrophages facilitate immunosuppressive responses and help cancer progression.

The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the exploding data transmission volume. Vortex beams, which exhibit a swirling shape around the axis of propagation, have the potential to increase the amount of information that can be stored at the same frequency.

A look at the architectures, tooling, and materials that make 3D NANDs, advanced DRAM, and 5nm SoCs possible.

A method to draw data in an area smaller than 10 nanometers has been proposed in a recent study published in Physical Review Letters

How advanced is the technology for creating live, moving organs for the human body using 3D printers? Bioprinting research in engineering tissues with bioink containing living cells has been on the rise. Depending on the method for assembling bioprinted tissues, larger tissues or organs can be created, which is leading to a new era of personalized treatment for patients.

A research team succeeds at observing high-resolution 3D structure of human chromosomes using the radiation accelerator.
