The use of polyurethanes and, therefore, the quantity its scrap are increasing. Considering thermoset characteristic most polyurethanes, circular recycling method is by means chemical depolymerization, for which glycolysis finding way into industry. main goal polyurethane to recover polyols used, but only limited attempts were made toward recovering aromatic dicarbamate residues and derivates f...

Inverse vulcanized polymer materials have received considerable attention as a way to use sulfur, an industrial byproduct, starting material for synthesis. The resulting high-sulfur content polymers also been investigated because their properties give rise promising applications such infrared imaging, energy storage, and heavy metal capture due unique structure. However, synthesis of flexible s...

Regulated secretion, nutrient uptake, and responses to extracellular signals depend on cell-surface proteins that are internalized and recycled back to the plasma membrane. However, the underlying mechanisms that govern membrane protein recycling to the cell surface are not fully known. Using a chemical-genetic screen in yeast, we show that the arginine transporter Can1 is recycled back to the ...

An innovative recycling process for thermoset polymer composites developed by Connora Technologies (Hayward, CA, USA) was studied. The process efficacy has already been tested, and it is currently working at the plant level. The main aspect investigated in the present paper was the environmental impact by means of the Life Cycle Assessment (LCA) method. Because of the need to recycle and recove...

RATIONALE The Amazon River is a huge network of long tributaries, and little is known about the headwaters. Here we present a study of one wet tropical Amazon forest side, and one dry and cold Atiplano plateau, originating from the same cordillera. The aim is to see how this difference affects the water characteristics. METHODS Different kind of water (spring, lake, river, rainfall) were samp...

The cover feature image shows that zinc guanidine complexes act with the yin-yang principle for bioplastics: they are able to promote controlled ring-opening polymerisation of lactide polylactide under industrial conditions but also recycling into lactates which go back value chain. Hence, corn as principal source can be saved since waste PLA serves resource allows multiple cycling valuable ren...

Ribosome recycling orchestrated by the ATP binding cassette (ABC) protein ABCE1 can be considered as the final-or the first-step within the cyclic process of protein synthesis, connecting translation termination and mRNA surveillance with re-initiation. An ATP-dependent tweezer-like motion of the nucleotide-binding domains in ABCE1 transfers mechanical energy to the ribosome and tears the ribos...

Endocytosis and recycling of membrane proteins are key processes for nutrient uptake, receptor signaling and synaptic transmission. Different steps in these fission and fusion cycles have been proposed to be regulated by physiological changes in plasma membrane (PM) phosphatidylinositol (4,5)-bisphosphate [PtdIns(4,5)P(2)] concentration. Here, we use a chemical enzyme-translocation strategy to ...
