New cost-effective method can detect low concentrations of pharmaceutical waste and contaminants in water
Pharmaceutical waste and contaminants present a growing global concern, particularly in the context of drinking water and food safety. Addressing this critical issue, a new study by researchers at Bar-Ilan University's Department of Chemistry and Institute of Nanotechnology and Advanced Materials has resulted in the development of a highly sensitive plasmonic-based detector, specifically targeting the detection of harmful piperidine residue in water.
DNA attached to nanoparticles found to contribute to lupus symptoms
Autoimmune diseases are mysterious. It wasn't until the 1950s that scientists realized that the immune system could harm the organs of its own body. Even today, the fundamental causes and inner workings of most autoimmune diseases remain poorly understood, limiting the treatment options for many of these conditions.
Scientists invent coin-sized device to rapidly isolate blood plasma for diagnostics and precision medicine
Scientists at Nanyang Technological University, Singapore (NTU Singapore), have developed a coin-sized chip that can directly isolate blood plasma from a tube of blood in just 30 minutes, which is more convenient and user-friendly as compared to the current gold standard, multi-step centrifugation process.
New method for analyzing nanoporous materials
In addition to their main components, the properties of crystalline and nanoporous materials often depend crucially on guest atoms or ions that are embedded in the tiny pores of their lattice structure. This applies to high-tech materials used in sensor or separation technology as well as to natural materials. The bluish gemstone aquamarine, for example, would be colorless without such guest components.
An approach to design high-power lithium sulfur batteries
Lithium-sulfur (Li-S) batteries are a promising alternative to lithium-ion batteries (LiBs), the most common rechargeable battery technology. As sulfur is abundant on Earth, these batteries could be cheaper and more environmentally friendly than LiBs, while also potentially exhibiting higher energy densities.
