Advances in Halide Perovskites for Photon Radiation Detectors
Advanced Materials Technologies, EarlyView.This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

Many current methods to prepare 2-hydroxybiaryls require the prefunctionalization of phenol groups or show limited substrate scope. Now, use of a pentavalent sulfone-bridged bismacycle, formed in situ by telescoped boron-to-bismuth transmetallation and oxidation, allows the direct and regioselective ortho-arylation of unprotected phenols.

A 19-year-old Crouzon's syndrome patient with a history of multiple craniofacial procedures presented with severe bilateral temporal and frontal depressions and metal implants protruding through the scalp in multiple locations. Preoperative analysis revealed an extensive cranial defect that had been reconstructed with multiple large metallic mesh ...

Biotechnology Progress, 1995
AbstractOnly within the past decade has the potential of metal biosorption by biomass materials been well established. For economic reasons, of particular interest are abundant biomass types generated as a waste byproduct of large‐scale industrial fermentations or certain metal‐binding algae found in large quantities in the sea.

Heavy metals have been identified as factors affecting human fertility. This study was designed to investigate whether the urinary heavy metal excretion is associated with different factors of infertility. The urinary heavy metal excretion was determined in 501 infertile women after oral administration of the chelating agent 2,3-dimercaptopropane-1 ...

Quarterly Reviews of Biophysics, 1974
Several reviews have been published recently on the toxicity of heavy metals, but few of these have made any reference to the influence of the nutritional state of animals upon their tolerance of heavy metals. Furthermore, the clinical and metabolic changes occurring as a consequence of increased dietary intake of heavy metals are extremely dependent ...

This brief review is focused on those heavy metals (cadmium, gold and mercury) that have strong associations with autoimmunity. Cadmium treatment of rats and mice results in autoimmune responses that vary with species and inbred strain of animals. However, there is no solid evidence demonstrating that the renal pathology observed in humans exposed to ...
