Chemical doping of MoS2 multilayer by p-toluene sulfonic acid
We report the tailoring of the electrical properties of mechanically exfoliated multilayer (ML) molybdenum disulfide (MoS2) by chemical doping. Electrical charge transport and Raman spectroscopy measurements revealed that the p-toluene sulfonic acid (PTSA) imposes n-doping in ML MoS2. The shift of threshold voltage for ML MoS2 transistor was analyzed as a function of reaction time. The threshol...
متن کاملp-Toluene-sulfonic acid, cholesterol determination, and explosions.
HAVE BEEN USING the method of Pearson, Stern, and McGavack (1) for the determination of cholesterol for some time. It has proved to be a convenient and accurate procedure and the reaction had always gone smoothly. One day recently, however, the tubes were set up for the determination as usual, using a freshly prepared solution of p-toluenesulfonic acid. Solutions made from the same bottle of so...
متن کاملDetermination of cholesterol with special reference to the use of p-toluene-sulfonic acid.
NTIL RECENT TIMES the methods for the determination of serum sterol have been difficult and time-consuming. As a result, the rmance of this analysis in hospital laboratories has often pred serious problems. It has been our aim to select a relatively and simple method, yet one with a practical degree of accuracy. reliminary investigation of a number of procedures for the detertion of cholesterol...
متن کاملInhibition of Amino Acid Transport in Rabbit Intestine by p-Chloromercuriphenyl Sulfonic Acid
Influx of phenylalanine across the brush border of rabbit intestine is markedly reduced by treatment with 5 mM p-chloromercuriphenyl sulfonate (PCMBS). The effect is rapidly and completely reversed by dithiothreitol. Phenylalanine influx into PCMBS-treated tissue can be competitively inhibited by other neutral amino acids and follows saturation kinetics. PCMBS causes an increase in the apparent...
متن کاملRapid and near-complete dissolution of wood lignin at ≤80°C by a recyclable acid hydrotrope
We report the discovery of the hydrotropic properties of a recyclable aromatic acid, p-toluenesulfonic acid (p-TsOH), for potentially low-cost and efficient fractionation of wood through rapid and near-complete dissolution of lignin. Approximately 90% of poplar wood (NE222) lignin can be dissolved at 80°C in 20 min. Equivalent delignification using known hydrotropes, such as aromatic salts, can...
