Advanced Energy Materials, EarlyView.Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

Distribution of Big Tau Isoforms in the Human Central and Peripheral Nervous System
Annals of Neurology, EarlyView.Objective Tau is widely studied in neurodegeneration, yet most work has focused on canonical brain tau isoforms. A longer isoform, “big tau,” produced by inclusion of exon 4a, is expressed in the peripheral nervous system (PNS) and central nervous system (CNS) regions.

Ultrasensitive detection of radioactive cesium isotopes using a magneto-optical trap [PDF]
SPIE Proceedings, 2002 We report the first magneto-optical trapping of mdioactive {sup 135}Cs and {sup 137}Cs and a promising means for detecting these isotopes to ullrasensilive lcvels by a system coupling the magneto-optical trap (MOT) to a mass separator. The mass separator efficiently delivers a 20 kV ion beam of either isotope into a quartzcube MOT cell having in one ...

Estimation of the contribution of gamma-emission of incorporated cesium radioisotopes in interpretation of the results of the public survey to assess the thyroidal iodine content following a radiation accident at the nuclear power plant [PDF]
Саратовский научно-медицинский журнал, 2014 Aim. A detail consideration has been done to assess an importance of the contribution of gamma-emission of incorporated cesium radioisotopes to the exposure rate measured near the thyroid by the public survey for following the Chernobyl accident ...

Discovery of Cesium, Lanthanum, Praseodymium and Promethium Isotopes
, 2011 Currently, forty-one cesium, thirty-five lanthanum, thirty-two praseodymium, and thirty-one promethium, isotopes have been observed and the discovery of these isotopes is discussed here. For each isotope a brief synopsis of the first refereed publication,

Oxygen isotopes and lakes [PDF]
, 2014 Isotopes are variations of a particular chemical element. It is all to do with the number of neutrons. Oxygen has two main isotopes: 18O which has 10 neutrons and 8 protons; and 16O which has 8 neutrons and 8 protons.

The Anatomical Record, EarlyView.Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

The Anatomical Record, EarlyView.Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

British Journal of Clinical Pharmacology, EarlyView.Aims CYP2C19 is one of the most important pharmacogenes, and its activity is highly variable due to factors such as genetics or drug–drug interactions. Due to the lack of an appropriate endogenous CYP2C19 biomarker, surrogate methods to assess its activity are warranted.
