Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators

open access: yesAdvanced Materials, EarlyView.
Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

New Solar Metallicity Measurements

open access: yesAtoms, 2019
In the past years, a systematic downward revision of the metallicity of the Sun has led to the “solar modeling problem„, namely the disagreement between predictions of standard solar models and inferences from helioseismology.

Metals and Metal Derivatives in Medicine

Mini-Reviews in Medicinal Chemistry, 2013
Several chemical elements are required by living organisms in addition to the four elements carbon, hydrogen, nitrogen and oxygen usually present in common organic molecules. Many metals (e.g. sodium, potassium, magnesium, calcium, iron, zinc, copper, manganese, chromium, molybdenum and selenium) are known to be required for normal biological functions

Cytotoxicity of metals, metal-metal and metal-chelator combinations assayed in vitro

Toxicology, 1986
A simple, rapid assay, based on the lysosomal incorporation of neutral red by cells, conveniently carried out in 96-well microtiter plates, was used to evaluate the cytotoxic effect of cationic and anionic metal salts on BALB/c mouse 3T3 fibroblasts.
