Synthesis and characterization of novel graft copolymers by radiation induced grafting [PDF]

open access: yes, 2010
The radiation-induced graft copolymerization of N-vinyl-2-pyrrolidone (NVP), 4-vinyl pyridine (4VP), 2-vinyl pyridine (2VP) monomers onto poly (ethylene-alt-tetrafluoroethylene) (ETFE) was investigated.

Characterization of a New Cyclohexylamine Oxidase From Acinetobacter sp. YT-02

open access: yesFrontiers in Microbiology, 2018
Cyclohexylamine (CHAM) is widely used in various industries, but it is harmful to human beings and the environment. Acinetobacter sp. YT-02 can degrade CHAM via cyclohexanone as an intermediate. In this study, the cyclohexylamine oxidase (CHAO) gene from

Solubilities of CL‐20 and MDNT in Organic Solvents for Technical Cocrystallization

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The 1:1 molar cocrystal of 2,4,6,8,10,12‐hexanitro‐2,4,6,8,10,12‐hexaazaisowurtzitane (CL‐20) and 1‐methyl‐3,5‐dinitro‐1,2,4‐triazole (MDNT) is reported to show a detonation velocity 100 m/s faster than β‐HMX. To establish a scalable synthesis method, the solubility of ε‐CL‐20 and MDNT was investigated.

Reactive organoallyl species generated from aryl halides and allene: allylation of alpha,beta-unsaturated aldehydes and cyclic ketones employing Pd/In transmetallation processes [PDF]

open access: yes, 2008
Allylation of α,β-unsaturated aldehydes and cyclic ketones promoted by Pd/In transmetallation processes has been studied. The unsaturated aldehydes underwent regioselective 1,2-addition to afford secondary homoally alcohols.

(2E)-2-[4-(Dimethylamino)benzylidene]-5-methylcyclohexanone

open access: yesIUCrData, 2017
In the title compound, C16H21NO, the cyclohexanone ring adopts a half-chair conformation; the dihedral angle between this ring (all atoms) and the benzene ring is 41.74 (16)°. No directional interactions could be identified in the crystal.

Ligand‐Controlled Tunable Distal C(sp2)–H Functionalization of Aryl and Benzyl Phosphonates

open access: yesTransformative Chemistry, EarlyView.
The switchable borylation of aryl and benzyl phosphonates with good to excellent regioselectivity was demonstrated. Through orthogonal transformation of Horner–Wadsworth–Emmons olefination and Suzuki–Miyaura cross coupling, a variety of styrene derivatives were obtained with precise site control.

Diathermy smoke: a risk to perioperative practitioners? [PDF]

open access: yes, 2014
The use of diathermy as a cautery device is common practice in perioperative environment, however issues relating to the health and safety of the smoke produced through the vaporisation of tissue may still not be recognised by practitioners.

Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.
