Researchers have developed a nonrelativistic and nonmagnetic approach to generate Terahertz (THz) waves, which can be used to probe the magnetic properties of new materials. Researchers use the anisotropic electrical conductivity of particular materials to directly exploit laser-excited, high-density charge currents across nanoscale metallic surfaces to harness the power of these currents to generate THz [..]

Raman spectroscopy—a method of evaluating substances by shining monochromatic light over a sample and seeing the emerging dispersed light—has frustrated biologists for more than fifty years. During the optical measurements, the heat generated by the light nearly kills living proteins, leading to decreased and non-repeatable findings. It appears that these hassles may be the past [..]

By examining exhaled air, researchers have created a non-invasive breath analyzer method to monitor the development of tiny blood clots called immunothrombosis. Due to inflammation, immunothrombosis can lead to serious consequences in individuals with severe COVID-19 and exacerbate sepsis, heart disease, diabetes, and other illnesses. The researchers created a non-invasive breath analyzer method that uses [..]

Although chemotherapy is a highly effective cancer treatment, some cancer cells become resistant to it through a dormant phase known as senescence. These therapy-induced senescent (TIS) cells can develop resistance to treatment, even become aggressive, and spread. Early TIS cell detection may be essential to stopping their spread; however, the screening techniques must be more [..]

When added to silicate glass, niobium oxide (Nb2O5) causes silica network polymerization, raising bond density and connectivity and improving specialty glass’s mechanical and thermal durability. It is the first study to demonstrate this effect. The work integrated computational modeling with actual Raman and nuclear magnetic resonance spectroscopy findings. In addition to the previously reported findings, [..]

When it comes to high-capacity screening tests, or assays, for detecting and targeting certain cells or analytes (substances whose chemical makeup is the goal of identification), the static droplet array (SDA) is an essential and fundamental instrument. One significant technological barrier that prevents the SDA’s wider use is the extraction and collection of target droplets [..]

Virtually applying makeup before completing a purchase or having pterodactyls swoop above in a game are just two examples of how augmented reality and other immersive technologies are changing how we play, watch, and learn. Immersion displays would realize their full potential using low-cost, ultra-small light-emitting diodes (LEDs) or micro-LEDs. However, these LEDs still need [..]

The rapid expansion of artificial intelligence (AI) and machine learning (ML) applications requires effective connectivity between processing units and high-speed transmission. It has increased interest in optical interconnects, especially for short-range connections between XPUs (CPUs, GPUs, and memory). When compared to conventional methods, silicon photonics is showing promise as a technology for enhanced performance, cost-effectiveness, and [..]

Transmission electron microscopes use inline holography to measure and rectify images in real space and to measure magnetic and electric fields. On the other hand, it needs help with incoherent dispersion and low-spatial-frequency information transmission. This work optimizes reconstruction parameters and compares the outcomes using gradient flipping, phase prediction, and incoherent background removal. Transmission electron [..]

Artificial materials that are skilled at influencing perception are called metasurfaces. Metasurfaces are attracting much interest as optical components that enable the miniaturization of optical systems for the next generation of virtual and augmented reality and LiDAR. They enable lenses to be shrunk to one 10,000th the size of normal lenses. Countries may gain a considerable [..]

Researchers have demonstrated that chip-based optical frequency combs with sufficient output power for optical atomic clocks and other practical applications may be made using dissipative Kerr solitons (DKSs).

According to a new study, artificial intelligence can forecast the on- and off-target behavior of CRISPR tools that target RNA rather than DNA. To manage the expression of human genes in various ways, the study combines a deep learning model with CRISPR screens—for example, by flipping a switch to fully turn them off or turning [..]

A high-resolution inelastic neutron scattering technique for examining nanosecond dynamics is neutron spin echo spectroscopy. It advances knowledge of viscoelasticity and is particularly suited to studying atomistic motion in polymer systems.
