Continuous process for engineering 2D transition metal dichalcogenide (TMDC) heterostructures — ScienceDaily

Researchers from Tokyo Metropolitan University have grown atomically thin crystalline layers of transition metal dichalcogenides (TMDCs) with varying composition over space, continuously feeding in different types of TMDC to a growth chamber to tailor changes in properties. Examples include 20nm strips surrounded by different TMDCs with atomically straight interfaces, and layered structures. They also directly…

X-ray imaging provides clues to fracture in solid-state batteries — ScienceDaily

Solid-state batteries — a new battery design that uses all solid components — have gained attention in recent years because of their potential to hold much more energy while simultaneously avoiding the safety challenges of their liquid-based counterparts. But building a long-lasting solid-state battery is easier said than done. Now, researchers at the Georgia Institute…

Researchers validate optimum composites structure created with additive manufacturing — ScienceDaily

Additive manufacturing built an early following with 3D printers using polymers to create a solid object from a Computer-Aided Design model. The materials used were neat polymers — perfect for a rapid prototype, but not commonly used as structural materials. A new wave of additive manufacturing uses polymer composites that are extruded from a nozzle…

Meeting minimum guidelines could prevent nearly one in two deaths linked to physical inactivity — ScienceDaily

Keeping physically active or becoming more active during middle and older age is associated with a lower risk of death, regardless of past activity levels or existing health conditions, suggests a large UK study published by The BMJ today. At the population level, meeting and maintaining at least the minimum public health recommendations (150 minutes…

When the diagnostic accuracy of coronary CT angiography matches that of catheter angiography — ScienceDaily

When a patient complains about chest pain, diagnosis will usually involve catheter angiography to evaluate the adequacy of blood supply to the heart. Researchers from Charité — Universitätsmedizin Berlin have now established that, in certain cases, the diagnostic reliability of non-invasive coronary computed tomography (CT) angiography is as good as that of coronary angiography —…

Chronic conditions — not infectious diseases — are top 5 causes of early death in China — ScienceDaily

Chronic diseases, such as stroke, ischemic heart disease, and lung cancer, now represent the leading causes of premature death in China, according to a new scientific study. The rise in non-communicable diseases reflects declines in maternal and child mortality over nearly three decades, largely the result of economic growth and increasing levels of education. In…

Understanding C. auris transmission with the healthcare environment — ScienceDaily

Researchers have now shown that patients who are heavily colonized with Candida auris on their skin can shed the fungus and contaminate their surroundings. This finding provides an explanation for the extensive contamination that often occurs in healthcare facilities with C. auris outbreaks. These results can help inform infection control efforts. The research is presented…
