Their findings refute existing theories on the displacement of the material’s atoms. Barium titanate is a ferroelectric material used in nearly all electronic devices – computers, smartphones and even electric cars. It’s used to make the sensors and capacitors they run on, for exa...

A closer look at how COVID-19 damages human lungs A recent study conducted at the United States Department of Energy’s (DOE) Brookhaven National Laboratory provides the first atomic-level detailed model of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) envelope protein when bound to human proteins within the lungs. The study was recently published in The utility of cryo-EM Cryo-electron microscopy (cryo-EM) is a high-resolution imaging technology that uses frozen samples, g...

Besides common symptoms such as fever, cough and respiratory distress, some children have an atypical form of COVID-19 known as multisystem inflammatory syndrome in children (MIS-C), characterized by persistent fever and inflammation of several organs, such as the heart and intestines, as well as the lungs to a lesser extent.

Driving the Nanotechnology Revolution with Nanoparticles Sponsored by EntegrisApr 29 2021 Many individuals and organizations consider nanotechnology to be the next technical revolution, with the potential to drastically change the modern world. Developments to date may not meet these expectations, but substantial investment from universities, industry and global governments currently exceeds $9 billion annually and is continuing to grow. 1 There has been an investment of $27 bil...

Purpose: The deposition of hydroxyapatite (HAp) crystals plays an important role in the development of vascular calcification (VC). This study aimed to demonstrate the effects of nanosized HAp (nHAp) on vascular smooth muscle cells (VSMCs) and VC progression. Methods: Transmission electron microscopy (TEM) was used to examine cellular uptake of nHAp. Cell viability was determined using CCK-8 assay kit. Mitochondrial impairment and reactive oxygen species were detected by TEM and fluorescence dy...
