Synthetized Potato Starch-A New Eco Sizing Agent for Cotton Yarns.

Stana Kovačević et al.

Polymers, 11(5) (2019-05-30)

The objective of this research was to verify the feasibility of the use of newly synthesized biopolymer materials for sizing cotton yarns based on the basic principles of chemical modification. Research included acid hydrolysis of potato starch up to controlled

Azobisisobutyronitrile initiated aerobic oxidative transformation of amines: coupling of primary amines and cyanation of tertiary amines.

Lianghui Liu et al.

Organic letters, 14(22), 5692-5695 (2012-10-31)

In the presence of a catalytic amount of radical initiator AIBN, primary amines are oxidatively coupled to imines and tertiary amines are cyanated to α-aminonitriles. These "metal-free" aerobic oxidative coupling reactions may find applications in a wide range of "green"

A novel urethane acrylate-based root canal sealer with improved degree of conversion, cytotoxicity, bond strengths, solubility, and dimensional stability.

Bor-Shiunn Lee et al.

Journal of endodontics, 37(2), 246-249 (2011-01-18)

We have developed new urethane acrylate-based root canal sealers using polycarbonate (PC) as polyol and 2,2-azobis(2-methyl)butyronitrile (AMBN) as a thermal initiator. The purpose of this study was to compare the properties among a group of seven sealers: (1) polybutyleneadipate (PBA)

Uniform PEO star polymers synthesized in water via free radical polymerization or atom transfer radical polymerization.

Wenwen Li et al.

Macromolecular rapid communications, 32(1), 74-81 (2011-03-25)

Amphiphilic star shaped polymers with poly(ethylene oxide) (PEO) arms and cross-linked hydrophobic core were synthesized in water via either conventional free radical polymerization (FRP) or atom transfer radical polymerization (ATRP) techniques using a simple "arm-first" method. In FRP, PEO based

Glucose-based amphiphilic telomers designed to keep membrane proteins soluble in aqueous solutions: synthesis and physicochemical characterization.

K Shivaji Sharma et al.

Langmuir : the ACS journal of surfaces and colloids, 24(23), 13581-13590 (2008-11-05)

A novel class of nonionic amphipols (NAPols) designed to handle membrane proteins in aqueous solutions has been synthesized, and its solution properties have been examined. These were synthesized through free radical cotelomerization of glucose-based hydrophilic and amphiphilic monomers derived from
