A matrix isolation and computational study of molecular palladium fluorides : does PdF₆ exist? [PDF]
, 2016 Palladium atoms generated by thermal evaporation and laser ablation were reacted with and trapped in F₂ /Ar, F₂ /Ne, and neat F₂ matrices. The products were characterized by electronic absorption and infrared spectroscopy, together with relativistic ...

A single cell death is disruptive to spontaneous Ca2+ activity in astrocytes
Frontiers in Cellular Neuroscience, 2022 Astrocytes in the brain are rapidly recruited to sites of injury where they phagocytose damaged material and take up neurotransmitters and ions to avoid the spreading of damaging molecules.

Laser Photolysis of Bilirubin [PDF]
Pediatric Research, 1981 Photodegradation of bilirubin in vitro has been investigated by using monochromatic light supplied by an argon ion laser selecting the 457.9, 488.0 and 514.5 nm wavelengths. Bilirubin was examined in chloroform, in aqueous solutions and in human serum under different experimental conditions of concentration, laser power and time of irradiance ...

Ultraviolet B (UVB) Photosensitivities of Tea Catechins and the Relevant Chemical Conversions
Molecules, 2016 Ultraviolet B (UVB) photosensitivities of eight catechins were screened. In both water and ethanol, epicatechin (EC, 575 μM) and catechin (C, 575 μM) exhibited low photostabilities under 6 h UVB radiation with the generation of yellow photoproducts ...

OH yields from the CH3CO+O-2 reaction using an internal standard [PDF]
, 2007 Laser flash photolysis of CH3C(O)OH at 248 nm was used to create equal zero time yields of CH3CO and OH. The absolute OH yield from the CH3CO + O2 (+M) reaction was determined by following the OH temporal profile using the zero time OH concentration as ...

Long wavelength single photon like driven photolysis via triplet triplet annihilation
Nature Communications, 2020 Photolysis has enabled the occurrence of numerous discoveries in chemistry, drug discovery and biology. However, there is a dearth of efficient long wavelength light mediated photolysis. Here, we report general and efficient long wavelength single photon
