Functionalization of Two‐Dimensional MoS2: On the Reaction Between MoS2 and Organic Thiols
TL;DR: The findings suggest that functionalization of two-dimensional MoS2 using organic thiols may not yield covalently or datively tethered functionalities, rather, in this instance, they yield physisorbed disulfides that are easily removed.

Experimental and theoretical Raman and surface‐enhanced Raman scattering study of cysteine
Guillermo Diaz Fleming,Justin J. Finnerty,Marcelo Campos-Vallette,Freddy Celis,A. E. Aliaga,Carlos Fredes,Rainer Koch +6 more
TL;DR: In this paper, the SERS spectrum with a large silver cluster as a model metallic surface was simulated for the first time, taking into account the experimental and calculated Raman and SERS vibrations and the corresponding assignments, as well as a comparison of force constants and geometrical parameters between the free zwitterion cysteine and the one in the presence of the colloidal silver nanoparticles, and the relative importance of the interaction of sulphyldryl, NH3+, and carboxylate groups with the metallic surface.

In situ Raman spectroscopy distinguishes between reversible and irreversible thiol modifications in L-cysteine
TL;DR: In situ Raman spectroscopy is found to effectively monitor the formation and subsequent breaking of disulphide bonds, and it is demonstrated that although TCEP is effective in breaking disul PH bonds, an excess of T CEP is required to reversibly form free thiol groups from L-cysteine.

TL;DR: Chirality plays a key role in many chemical and biological systems, with chiral molecules and materials critical for the further development of biopharmaceuticals and fine chemicals, and this research should have a strong impact on relevant areas of science and technology such as nanobiotechnology, nanomedicine, and nanotoxicology.

Pressure-induced phase transitions in crystalline L- and DL-cysteine.
Vasil S. Minkov,Alexander S. Krylov,Elena V. Boldyreva,S.V. Goryainov,Sergei N. Bizyaev,Alexander Vtyurin +5 more
TL;DR: The role of the movements of the side -CH 2SH groups and of the changes in the hydrogen-bonding type in dl- and l-cysteine during the phase transitions with increasing pressure is discussed and compared with that on cooling down to 3 K.

Neutron scattering, infra red, Raman spectroscopy and ab initio study of L-threonine.
TL;DR: Inelastic incoherent neutron scattering spectra (IINS) were obtained for normal and deuterated L-threonine using ab initio Hartree-Fock levels and force fields and normal modes were calculated and used as basis for an assignment of the spectral features.
