Poly (N-isopropylacrylamide-acrylic acid) [p(NIPAM-AAc)] microgel was successfully fabricated using the precipitation polymerization method. Silver (Ag) nanoparticles and graphene oxide (G) were used to fabricate following hybrid microgels: Ag-p(NIPAM-AAc) (Ag-HMG), Ag-G-p(NIPAM-AAc) (Ag-G-HMG), G-p(NIPAM-AAc) (G-HMG). Ag-HMG, Ag-G-HMG, G-HMG characterized a Zetasizer UV-Vis spectroscopy. The r...

Excessive water production through fractures become an important problem in oil exploration of fractured reservoirs. For this purpose, polymer gels were prepared by crosslinking of aqueous solutions of polymer and crosslinker for the purpose of water management in high water cut fractured reservoirs. A copolymer of sulfonated polyacrylamide was used as polymer and chromium triacetate (Cr(OA...

Nitrite contaminants in freshwater streams, resulting from run-off of fertilizers and livestock farming, are a major ecological challenge. Here, we have developed new family catalysts based on Pd/Al2O3 coated with N-isopropylacrylamide polymer (p-NIPAM) brushes that increase N-N bond formation over N-H formation, promoting nitrogen selectivity by 3-fold, reaching >99% for the containing 20 wt% ...

The main objective of this study is to prepare, thermally, sensitive microgel particles bearing thiol groups via precipitation polymerization of N-isopropylacrylamide (NIPAM), methylenebisacrylamide (MBA) and vinylbenzylisothiouronium chloride (VBIC) using 2-2'-azobis(2-amidinopropane)-dihydrochloride (V50) as initiator. The influence of various parameters has been investigated as a systematic ...

One of treatment planning techniques with Leksell GammaPlan (LGP) for Gamma Knife stereotactic radiosurgery (GKSRS) uses multiple matrices with multiple dose prescriptions. Computational complexity increases when shots are placed in multiple matrices with different grid sizes. Hence, the experimental validation of LGP calculated dose distributions is needed for those cases. For the current stud...

The Front Cover shows the interplay between chemisorption of carbon monoxide probe molecules and diffusion through a porous catalyst with stimulus responsive polymeric brushes that can switch transfer process ON- OFF temperature. In their Research Article, M. J. Enes da Silva et al. showed on Polymer-Membrane-Catalyst Assembly (PCMA) system consisting PET membranes well-defined pore structure c...

Cellulose nanocrystals (CNCs) from ramie fibers are studied as stabilizers of oil-in-water emulsions. The phase behavior of heptane and water systems is studied, and emulsions stabilized by CNCs are analyzed by using drop sizing (light scattering) and optical, scanning, and freeze-fracture electron microscopies. Water-continuous Pickering emulsions are produced with cellulose nanocrystals (0.05...
