A Practical Guide to Plastics Sustainability ScienceDirect

Several examples of industrially recycled plastic performances include polyamides, polystyrene, acrylonitrile butadiene styrene (ABS), polypropylene, polycarbonate (PC), and its alloys PC/ABS and PC/polybutylene terephthalate; as well as polyetherimide. Cost and pollution savings are also pointed out before an examination of some limitations. A correlation between chemistry, polarization, and dust Pre-stellar cores within molecular clouds provide the very initial conditions in which stars are formed. FeSt 1-457 is a prototypical starless core and the most chemically evolved among those isolated, embedded in the most pristine part of the Pipe nebula, the bowl. We use the IRAM 30 m telescope and the PdBI to study the chemical and physical properties of the starless core FeSt 1-457 (Core

A new Al14Co28Cr28Ni30 hypoeutectic high entropy alloy

Oct 16, 2019 · In this study, a new Fe-free Al 14 Co 28 Cr 28 Ni 30 hypoeutectic high entropy alloy was designed and investigated in detail. The alloy exhibited a typical hypoeutectic microstructure composed of primary phase (FCC structure) and eutectic organization (FCC + B2 mixture structure). The FCC phase is enriched in Co and Cr elements, while the B2 Comparison of chemical, physical, and ultrasound Dec 27, 2019 · The study was conducted to examine the effect of chemical treatment (ascorbic acid and calcium chloride), physical treatment (water bath at 65 °C), and ultrasound (US) in ultrasonic bath for the prevention of enzymatic browning of fresh-cut quince slices during 14 days of storage. Evaluation of the morphology, mechanical and thermal Jul 26, 2019 · Currently, the construction industry is the second largest consumer of plastics in the world, using 19% of world production and losing only to the packaging sector with 42% [], given the lightness and durability of these materials [].However, there is a limitation in the use of this material in external applications, mainly due to its high instability against physical factors such as UV solar

Guide Gloves. Akwel reduced hand injuries by up to 30% in partnership with Guide Gloves Employees of the global supplier of pipes and components to the automotive industry are exposed to a number Hanwha General Chemical HanwhaHanwha Chemical Established in 1965, Hanwha Chemical is a total solutions chemical company with streamlined production systems for polyethylene (PE), polyvinyl chloride (PVC), and chlor-alkali (CA). As South Koreas leading petrochemical company, we dominate the nations chemical industry with high-quality PVC, CA, and linear low-density polyethylene (LLDPE) that we offer at competitive Mapping exercise Plastic additives initiative - ECHAMapping exercise Plastic additives initiative. The joint project by ECHA and industry resulted in a list of over 400 functional additives or pigments used in plastics, including information on the polymers they are most commonly found in and the typical concentration ranges. The mapping considered substances registered under REACH at above

Phenolic Extract from Propolis and Bee Pollen:Composition

Jun 15, 2015 · In this study, antioxidant properties and in vitro antibacterial activity of honeybee pollen and propolis methanol extracts were determined. Propolis with higher phenolic content showed significant greater activity over pollen extracts. Caffeic acid, ferulic acid, rutin, and p -coumaric acid were detected as main phenolic compounds in propolis extract. 3,4-Dimethoxycinnamic acid was the major phenolic Phys. Rev. B 96, 075161 (2017) - Andreev bound states Aug 30, 2017 · Motivated by an important recent experiment [Deng et al., Science 354, 1557 (2016)], we theoretically consider the interplay between Andreev and Majorana bound states in disorder-free quantum dot-nanowire semiconductor systems with proximity-induced superconductivity in the presence of spin-orbit coupling and Zeeman spin splitting (induced by an external magnetic field). The quantum dot [1906.03412] A Two-Step Graph Convolutional Decoder for Jun 08, 2019 · Numerical experiments on basic tasks such as novelty, uniqueness, validity and optimized chemical property for the 250k ZINC molecules demonstrate the performances of the proposed system. Particularly, we achieve the highest reconstruction rate of 90.5\%, improving the previous rate of 76.7\%.
