The area of thin-film photovoltaics has been overwhelmed by organometal halide perovskites. Unfortunately, serious stability concerns arise with perovskite solar cells. For example, methyl-ammonium lead iodide is known to decompose in the presence of water and, more severely, even under inert conditions at elevated temperatures. Here, we demonstrate inverted perovskite solar cells, in which the...

Iodine is an elemental nutrient that is essential for mammals. Here we provide evidence for an acute therapeutic role for iodine in ischemia reperfusion injury. Infusion of the reduced form, iodide, but not the oxidized form iodate, reduces heart damage by as much as 75% when delivered intravenously following temporary loss of blood flow but prior to reperfusion of the heart in a mouse model of...

Enantiopure secondary alcohols are fundamental high-value synthetic building blocks. One of the most attractive ways to get access this compound class is catalytic hydroboration. We describe a new concept for reaction type that allowed exceptional turnover numbers (up 15 400), which were increased by around 1.5–3 orders magnitude compared active catalysts previously reported. In our an aprotic ...

In spite of the outstanding properties metal halide perovskites, its polycrystalline nature induces a wide range structural defects that results in charge losses affect final device performance and stability. Herein, surface treatment is used to passivate interfacial vacancies improve moisture tolerance. A functional organic molecule, phenylethyl ammonium iodide (PEAI) salt, dissolved with anti...

Methacryloxylethyl cetyl ammonium chloride (DMAE-CB) is a polymerizable antibacterial monomer and has been proved as an effective strategy to achieve bioactive bonding with reliable bacterial inhibitory effects. However, the toxicity of DMAE-CB may hamper its wide application in clinical situations. Thus, this study was designed to investigate the toxicity of DMAE-CB and explore the possible pr...

We have evaluated the electric characteristics of an organic surfactant material, n-Cethyl-trimethyl-ammonium Bromide (C16TAB) to fabricate the p-n homo-junction. This C16TAB was dissolved in the pure water, where the potassium iodide (KI) was added. The impurities adaptation has been processed in this mixed solution with the application of voltage. The KI is ionized in the water and the potass...

Cationic liposome transfection reagents are useful for transferring polynucleotides into cells, and have been proposed for human pulmonary gene therapy. The effect of adding cholesterol to cationic lipid preparations has been tested by first formulating the cationic lipid N-[1-(2,3-dioleoyloxy)propyl-N-[1-(2-hydroxy)ethyl]-N,N-dimethyl ammonium iodide (DORI) with varying amounts of dioleoylphos...

N-Alkyl ammonium resorcinarene salts (NARYs, Y=triflate, picrate, nitrate, trifluoroacetates and NARBr) as tetravalent receptors, are shown to have a strong affinity for chlorides. The high affinity for chlorides was confirmed from a multitude of exchange experiments in solution (NMR and UV/Vis), gas phase (mass spectrometry), and solid-state (X-ray crystallography). A new tetra-iodide resorcin...

The title compound crystallizes in the orthorhombic, noncentrosymmetric space group Pna2(1) with a = 10.241(11), b = 12.903(12), c = 9.312(9) A and with one formula unit per asymmetric unit. The stereochemically comparable torsion angles of the cation of 1 and of acetylcholine chloride are analogous. In the crystal structure the trimethylammonio methyl group is surrounded by three anions in the...

For the purpose of biochemical studies utilizing radioiodine 1131 as a tracer material, it is desirable to have a simple, sensitive, and thoroughly validated method for the measurement of the radioactivity of the biological samples. The present investigation was undertaken to provide such a method, with part,icular reference to the thyroid of the rat, but is adaptable with appropriate modificat...
