Spiral Galaxies as Enantiomers: Chirality, an Underlying Feature in Chemistry and Astrophysics
, 2005 Spiral galaxies are axi-symmetric objects showing 2D-chirality when projected onto a plane. Features in common with tetrahedral molecules are pointed out, in particular the existence of a preferred chiral modality for genetic galaxies as in aminoacids ...

Sulfoxides: potent co-crystal formers [PDF]
, 2013 The design of co-crystals requires knowledge of robust supramol. synthons. The sulfoxide is a potent H bond acceptor and was used as a co-crystal former with a range of NH functional groups, via N-H···O=S H bonds.

Defective hierarchical porous copper-based metal-organic frameworks synthesised via facile acid etching strategy [PDF]
arXiv, 2019 Introducing hierarchical pore structure to microporous materials such as metal-organic frameworks (MOFs) can be beneficial for reactions where the rate of reaction is limited by low rates of diffusion or high pressure drop. This advantageous pore structure can be obtained by defect formation, mostly via post-synthetic acid etching, which has been ...

Advanced Functional Materials, EarlyView.Oxygen‐doping modulated g‐C3N4 support enables a strong built‐in electric field (BIEF) in FeOCl‐OCN.This enhanced BIEF induces the rearrangement of Fe(II)/Fe(III) in FeOCl, which subtly improves intermediates adsorption and also reduces the energy barrier of *O production, thereby achieving efficient PMS activation with 1O2 and Fe(IV)= O as the primary

The Electrochemical Oxidation of Organic Selenides and Selenoxides [PDF]
, 1997 The electrochemical oxidation of alkyl and aryl selenides was investigated in acetonitrile. The oxidation of diphenyl selenide and di(4‐methylphenyl) selenide led primarily to the formation of their respective selenoxides, which were identified by ...
