High molecular weight polyacrylamide synthesis - The
Ultra-high molecular weight acrylamide copolymers and ultra-high molecular weight polyacrylamide are very valuable as EOR injection water viscosifiers since their ultra-high molecular weight allows them to viscosify an aqueous solution to a given viscosity at lower polymer concentrations than do corresponding acrylamide polymers of lesser

Ultra-high molecular weight (UHMW, M n > 1000 kDa) polymeric drift control adjuvants (DCAs) for agricultural spraying are prone to mechanical degradation and rapidly lose performance. To overcome this, we have designed linear coordination polymers (LCPs) composed of 400 kDa telechelic bis-terpyridine end-functionalised polyacrylamide units, which ‘self-heal’ upon shearing through
Inverse Emulsion Polymerization for the Synthesis of High
Polyacrylamides constitute a class of polymers that can entirely dissolve or swell in water to form a solution or hydrogel, respectively. Free radical polymerization of acrylamide monomer, using both solution and inverse emulsion polymerization, was applied to produce polyacrylamide with various molecular weights. This investigation was focused on the production of polymers with varying
We synthesise polyacrylamide microgels by polymerization of monomer solutions in emulsion droplets as a template. In a round bottom flask, we mix 100 ml kerosene with 1%wt of the surfactant
Processes | Free Full-Text | Bacterial Cellulose
The unique pool of features found in intracellular and extracellular bacterial biopolymers attracts a lot of research, with bacterial cellulose (BC) being one of the most versatile and common. BC is an exopolysaccharide consisting solely of cellulose, and the variation in the production process can vary its shape or even its composition when compounding is applied in situ. Together with ex
Introduction. Natural products and their synthetic derivatives provide important clinically used therapeutic agents, accounting for 73% of antibacterial agents and 83% of anticancer agents approved by the Food and Drug Administration between 1981 and 2014 [].Polyketides represent a central class of these natural products, with remarkably targeted and potent pharmacological properties and

Introduction. Macroautophagy (hereafter autophagy) targets the delivery of intracellular content to the lysosomal compartments, via the formation of double-membraned vesicles termed as autophagosomes 1–4.Autophagy is controlled by a set of evolutionarily conserved autophagy-related proteins 5, occurs at a basal level in all eukaryotic cells, including the unicellular organisms 6, and is
