Light-emitting diodes (LEDs) have revolutionized the lighting industry with their energy efficiency and long lifespan. However, defects in these devices often hamper their performance. While the mechanisms behind the impact of defects on LEDs emitting red or green wavelengths are well understood, the same cannot be said for blue or ultraviolet emitters. Nevertheless, researchers at

Scientists have long been puzzled by the composition and structure of Earth’s core, but a recent breakthrough in iron synthesis may provide some answers. A team of physicists and geologists from CEA DAM-DIF, Université Paris-Saclay, and the European Synchrotron Radiation Facility, have successfully synthesized a single-crystalline form of iron that mimics the iron found in
In the ever-evolving world of scientific research, the demand for automation and efficiency has led to the development of technologies that enable quick experiments and precise handling of small amounts of liquids. One such challenge is the manipulation of droplets ranging from picoliters to microliters. Traditional digital microfluidic technology has its limitations, with a maximum
The world of materials science is filled with fascinating discoveries that continue to push the boundaries of our understanding. One such discovery, reported in a recent study published in Nature, explores the unique properties of antiferromagnets and their potential applications in ultra-precise and ultrafast motion control. By harnessing the power of electron spin and manipulating
In a groundbreaking study published in the journal Science Advances, an international team of physicists has demonstrated the efficacy of deep-learning artificial intelligence (AI) technology in accurately quantifying the level of entanglement in quantum systems. Previous research has shown that the extent of “quantumness” can be represented by a single number, but measuring this entanglement
In a groundbreaking study conducted by a research team led by Prof. Yossi Paltiel at the Hebrew University of Jerusalem, the influence of nuclear spin on biological processes has been unveiled. This discovery challenges long-held assumptions and paves the way for exciting possibilities in the realms of biotechnology and quantum biology. The findings, published in
The field of quantum physics has long grappled with the challenge of efficiently synchronizing individual and independently generated photons. Such synchronization would have significant implications for quantum information processing, particularly in regards to the interactions between multiple photons. Researchers at the Weizmann Institute of Science have recently made progress in this area, using an atomic
The search for long-lived heavy neutral leptons (HNLs), also known as sterile neutrinos, has recently garnered attention in the particle physics community. In a recent study, the CMS collaboration presented new results on the detection of these hypothetical particles. HNLs have the potential to solve several mysteries in the field, including the smallness of neutrino
Fracture mechanics, a field that has long been studied and understood, has recently been turned on its head by researchers at the Racah Institute of Physics, Hebrew University of Jerusalem. Led by Dr. Meng Wang, Dr. Songlin Shi, and Prof. Jay Fineberg, this team has made a groundbreaking discovery that challenges the conventional understanding of
For over 150 years, Kirchhoff’s law of thermal radiation has stood as an undisputed principle in the field of physics. However, recent groundbreaking research conducted by Harry Atwater’s lab at the California Institute of Technology (Caltech) challenges this long-held belief. Through the development of an innovative device, the traditional relationship between an object’s absorbed and
In the realm of materials, two main categories dominate: metals and insulators. Metals, such as copper and iron, possess free-flowing electrons that enable them to conduct electricity. On the other hand, insulators like glass and rubber have tightly bound electrons and therefore do not conduct electricity. This stark contrast in behavior has long fascinated scientists
Researchers in various scientific fields have been striving to develop innovative techniques for imaging weakly scattering phase objects, such as cells. Chemical stains and fluorescent tags have traditionally been used to enhance image contrast, but these methods often involve complex and potentially toxic sample preparation steps. However, a breakthrough in the form of quantitative phase
