This work demonstrates enhanced valley contrasting spin-momentum locked chiral states at the van der Waals interface of L-cysteine and single layer (SL) MoS 2 placed on a Si/SiO substrate ambient conditions. Helicity dependent photoluminescence resonance Raman measurements highlight spin-locked transitions for modified SL-MoS Selective adsorption dimer/cysteine stabilizes in-plane effective mag...

Bi-Pr-O composite nanoflakes were synthesized with the aid of polyvinyl pyrrolidone (PVP) as surfactant. The characterization was performed by X-ray diffraction and electron microscopy. prepared consisted tetragonal Bi2O3, hexagonal Pr2O3, Bi0.4Pr0.6O1.5 smooth surface. size whole is less than 1 μm thickness 100 nm. formation can be explained a PVP-assisted growth mechanism. A systematic study ...

An activity-based probe, containing an irreversibly locked GFP-like fluorophore, was synthesized and evaluated as an inhibitor of human cathepsins and, as exemplified with cathepsin K, it proved to be suitable for ex vivo imaging and quantification of cysteine cathepsins by SDS-PAGE.

The molecular conformations of crystalline L-cysteine prepared in its orthorhombic form were determined by the vibrational cross angle measurements. Its major dihedral angles of chemical bonds determined by this method are consistent with the results from diffraction experiments. In addition, the relative orientations of the chemical bonds associated with the hydrogen atoms of the NH3(+) group ...

Mollisianitrile (1), a new antibiotic was isolated from the fermentation broth of Mollisa sp. A59-96 together with the two known isocoumarins 2 and 3. 1 exhibited antimicrobial, cytotoxic, and phytotoxic activities. 1 contains a reactive propiolonitrile moiety which is believed to be responsible for its antibiotic activities. Upon incubation with L-cysteine the biological activity was lost.

The Phadebact Gonococcus Test (Pharmacia Diagnostics, Piscataway, N.J.) is used for the identification of Neisseria gonorrhoeae. In this test, boiled organisms are examined by using a 3-min coagglutination technique. A total of 313 isolates of Neisseria confirmed by the fluorescent-antibody technique or identified to the species level by the cysteine-tryptose agar utilization technique, were te...
