The switching of quadratic nonlinear optical (NLO) effects between two or more NLO states solid-state materials represents an intriguing new branch in the field photoelectrics and optics. While structural phase transitions have shown potential this field, near-room-temperature reversible switches rarely been reported. To exploit within structurally flexible class hybrid perovskites, here, we sy...

The green ciliate Paramecium bursaria contains several hundred symbiotic Chlorella species. We previously reported that symbiotic algal carbon fixation is enhanced by P. bursaria extracts and that the enhancing factor is a heat-stable, low-molecular-weight, water-soluble compound. To identify the factor, further experiments were carried out. The enhancing activity remained even when organic com...

The role of membrane phosphatides in transport processes has been investigated in red cells from splenectomized patients with hereditary spherocytosis (HS). Incorporation of inorganic (32)phosphate into the membrane phosphatides of HS red cells was approximately twice normal, coinciding with the nearly twofold increment in flux of sodium ions in the cells.A consistent, inordinate increase in sp...

Colloidal semiconductor nanocrystals, with intense and sharp-line emission between red and near-infrared spectral regions, are of great interest for optoelectronic and bio-imaging applications. The growth of an inorganic passivation layer on nanocrystal surfaces is a common strategy to improve their chemical and optical stability and their photoluminescence quantum yield. In particular, cation ...

Magic blue (MB+˙ SbCl6− salt), i.e. tris-4-bromophenylamminium cation radical, is a routinely employed one-electron oxidant that slowly decomposes in the solid state upon storage to form so called ‘blues brothers’, which often complicate the quantitative analyses of the oxidation processes. Herein, we disclose the identity of the main ‘blues brother’ as the cation radical and dication of tetrak...

Malate in beet discs treated in different salt solutions was labeled by a 30 min pulse of (14)CO(2), and subsequent changes in specific activity were followed for several hr. In treatments which resulted in net acid synthesis in response to excess cation absorption, malate specific activity fell slowly after removal of (14)CO(2). In solutions where no net acid synthesis occurred, and from which...

1. A study of the effect of denervation on the inorganic cation content of muscle has been carried out. In this study 69 rats were employed. 2. By using the flame photometer for the estimation of sodium and potassium and increasing the sensitivity of previous methods for the estimation of calcium and magnesium, it has been possible to carry out analyses for all these ions on as little as 0.5 gm...

In the past few years, the meteoric development of hybrid organic-inorganic perovskite solar cells (PSC) astonished the community. The efficiency has already reached the level needed for commercialization; however, the instability hinders its deployment on the market. Here, we report a mechanism to chemically stabilize PSC absorbers. We propose to replace the widely used methylammonium cation (...

INTRODUCTION Accurate and precise determination of inorganic As (III/V) redox species is important in the interpretation of its toxicity and mobility in acid mine waters. Several analytical methods use arsine generation to separate arsenic species but high metal concentrations can suppress arsine production (Creed and others 1996). The potential inhibition of arsine formation by eleven metal sp...

BACKGROUND Genome-wide association studies (GWAS) represent the current frontier in pharmacogenomics. Thousands of subjects of Caucasian ancestry have been included in previous GWAS investigating antidepressant response. GWAS focused on this phenotype are lacking in Asian populations. METHODS A sample of 109 major depressive disorder (MDD) patients of Korean origin in antidepressant treatment...
