Researchers have developed a new pH probe and imaging technique to provide researchers more information when studying diseases like cancer and Alzheimer’s. Now, University of Cincinnati cancer biologists have developed a new piece of technology and a new imaging technique that will help researchers glean more detailed data points and see cells in more precise…

Researchers have used electron energy loss spectroscopy to directly measure the coefficient of thermal expansion at grain boundaries in the polycrystalline material SrTiO3. The researchers identified differences in the coefficient of expansion depending on the grain boundary. In addition to revealing the thermal properties of SrTiO3, the findings demonstrate the potential of EELS for probing…

Researchers directly monitored the increase in temperature that occurs when ionic current passes through a nanopore. By using a thermocouple, the team was able to show nearly linear behavior with applied voltage. This work may help lead to the creation of new nanoscale sensors. Nanopores, which are tiny openings in a membrane so small that…

A new study demonstrates ‘species agnostic’ screening of lipid nanoparticles, which could significantly accelerate the development of cutting edge mRNA targeted therapies. Long before the Covid-19 pandemic put a global spotlight on mRNA-based vaccines, these two researchers in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University were combining their…

Sea pineapples are a delicacy in Japan and the Tohoku region is renowned for its extensive sea pineapple industry. Soon they might not only be fueling our appetites, but helping power our future too. A research group demonstrated that the carbonization of cellulose nanofibers within sea pineapple shells produces high-quality carbon that, when mixed with…

Researchers have developed new antimicrobial technology for air filters which can in seconds kill bacteria, fungi and viruses including SARS-CoV-2 — providing a potential solution to prevent the spread of airborne infections. In a study, published today (9 March 2022) in journal Scientific Reports, the antimicrobial treatment for air filters — coated with a chemical…

Scientists combine two promising photocatalysts to obtain higher solar-to-hydrogen conversion efficiency and durability in a water splitting cell. One way to do that is by splitting water via «artificial photosynthesis,» a process in which materials called «photocatalysts» leverage solar energy to produce oxygen and hydrogen from water. However, the available photocatalysts are not yet where…

Scientists studied the inner workings of a solar cell material using X-ray and neutron scattering. The study revealed that liquid-like motion in the material may be responsible for their high efficiency in producing electric currents from solar energy. Perovskites, a class of materials with a unique crystal structure, could overtake current technology for solar energy…

Researchers have published the results of a new study evaluating the acoustic effects of face masks on speech. The team tested medical masks, disposable surgical masks, masks with clear plastic windows around the mouth, and homemade and store-bought cloth masks made of different fabric types and numbers of layers. Corey, an electrical and computer engineering…

Lysosomes are organelles that play essential roles in cellular digestion and waste management, and lysosomal dysfunction typically leads to serious diseases. In a recent study, scientists developed a novel technique to extract intact lysosomes from cells using magnetic nanoparticles. Their approach is much faster than previous methods and yields samples with high purity, allowing for…
