Fabrication of multi-level carbon nanotube arrays with adjustable patterns.

Nanoscale

Gong J, Sun L, Zhong Y, Ma C, Li L, Xie S, Svrcek V.
PMID: 22080290
Nanoscale. 2012 Jan 07;4(1):278-83. doi: 10.1039/c1nr11191d. Epub 2011 Nov 14.

Multi-level carbon nanotube (CNT) arrays with adjustable patterns were prepared by a combination of the breath figure (BF) process and chemical vapor deposition. Polystyrene-b-poly(acrylic acid)/ferrocene was dissolved in carbon disulfide and cast onto a Si substrate covered with a...

Very simple chemistry can result in the rapid and high-yield production of key prebiotic inorganic molecules. The two reactions investigated here involve such simple systems, (a) carbon disulfide (CS

Photosensitized formation of sulfate and volatile sulfur gases from dissolved organic sulfur: Roles of pH, dissolved oxygen, and salinity.

Sci Total Environ. 2021 Sep 10;786:147449. doi: 10.1016/j.scitotenv.2021.147449. Epub 2021 Apr 30.

The photodegradation of dissolved organic sulfur (DOS) is a potential source of aqueous sulfate and its chemical precursors in surface water. However, the photochemical fate of DOS and factors that control its fate still remain unclear. Herein, we employed...

Synthesis and Characterization of a Ring-Opening Oxaspiro Comonomer by a Novel Catalytic Method for Denture Base Resins.

Journal of pharmacy & bioallied sciences

Ajay R, Rakshagan V, Ganeshkumar R, Ambedkar E, RahmathShameem S, Praveena K.
PMID: 34447146
J Pharm Bioallied Sci. 2021 Jun;13:S521-S526. doi: 10.4103/jpbs.JPBS_524_20. Epub 2021 Jun 05.

BACKGROUND: 3,9-Dimethylene-1,5,7,11-tetraoxaspiro[5,5]undecane (DMTOSU) is a double ring-opening monomer that exhibits expansion upon polymerization and may be used as a denture base resin's comonomer to offset or minimize polymerization shrinkage. It's synthesis by transesterification reaction (TE) catalyzed by distannoxane is...

A Dimroth rearrangement approach for the synthesis of selenopheno[2,3-e][1,2,4]triazolo[1,5-c]pyrimidines with cytotoxic activity on breast cancer cells.

PMID: 34357512
Mol Divers. 2021 Aug 06; doi: 10.1007/s11030-021-10290-8. Epub 2021 Aug 06.

New selenopheno[2,3-e][1,2,4]triazolo[1,5-c]pyrimidine derivatives have been synthesized via Dimroth rearrangement by cyclocondensation of 7-cyano-4-hydrazinyl-6-(pyrrolidin-1-yl)selenopheno[3,2-d]pyrimidine with electrophilic carbons of either orthoesters in acetic acid or carbon disulfide in pyridine followed by S-alkylation. All the newly synthesized products have been structurally elucidated....
