Effect of Side Groups on the Surface Parameters and Antifouling Properties of Poly(N‐Alkyl Acrylamide)‐Coated Surfaces

Macromolecular Chemistry and Physics, EarlyView.
This study unravels the effect of the side groups on the surface parameters and antifouling properties of a library of acrylamide‐based polymers, pPAM, pEAM, pFEAM, and pHEAM synthesized by RAFT polymerization. Polymer chains of DP = 25, 50, 75, and 100 are used for coating gold surfaces employing the “grafting‐to” approach.

Random Laser Emission at Dual Wavelengths in a Donor-Acceptor Dye Mixture Solution [PDF]

arXiv, 2016
The work was aimed to generate random laser emissions simultaneously at two wavelengths in a weakly scattering system containing mixture of binary dyes, rhodamine-B (Rh-B) and oxazine-170 (O-170) dispersed with ZnO nano-particles served as scattering centres.

Transition Metal-Free Cascade Cyclization of Epoxy-Ynamides: To Go for 1,3-Oxazines or 1,4-Oxazines?

Organic Letters, 2016
An approach to both 1,3- and 1,4-oxazines is developed by the cascade cyclization of epoxy ynamides under transition metal-free conditions. Thus, while 1,3-oxazines are obtained in a regio- and stereoselective manner by using base, cyclization of epoxy ...

Development of High‐Performance Ablative Composites: Synergistic Effects of Alumina Particles and Silica Fabric in the Polybenzoxazine Matrix

Polymer Composites, EarlyView.
The illustration depicts the improvement in the mechanical and ablative properties of polybenzoxazine composites according to their alumina particle content. ABSTRACT The aerospace industry is seeking a replacement of toxic phenolics to use in ablative materials. One of the most promising candidates is polybenzoxazine materials because of their extreme

The Copolymerization Performance of 2‐Cyclopropyl‐2‐Oxazoline and 2‐Cyclopropyl‐2‐Oxazine Contributes to Tunable Temperature‐Responsive (Co)Polymer Characteristics

Journal of Polymer Science, EarlyView.
Using the cationic ring‐opening polymerization method: homopolymers and heteropolymers with tailored temperature response are generated from 2‐cyclopropyl‐2‐oxazoline and 2‐cyclopropyl‐2‐oxazine. The strategy allows for maintaining the same side chains and addressing the influence of the ring size of the cyclic imino ether regarding its kinetics and ...

Chemical constitutions in the Colour Index™: A century of colourant classification

Coloration Technology, EarlyView.
Abstract This article details how the Colour Index™ (CI) system categorises and unambiguously labels commercial dyes and pigments based upon their chemical constitutions. It outlines the current process by which colourants that are new to the market find a place within CI and acquire generic identifiers.

Overestimation of Automated Platelet Counts by Blast Fragments in Acute Hypercellular Leukemias: A Retrospective Study Comparing Impedance, Optical (PLT‐O), Fluorescent (PLT‐F), and CD41/CD61 Flow Cytometry Methods

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction Acute leukemias with hyperleukocytosis (> 100 × 109/L) can produce cytoplasmic blast fragments that interfere with platelet counts, notably in impedance‐based methods, potentially masking severe thrombocytopenia and increasing hemorrhagic risk.
