HETEROJUNCTION INDUCTED NICKEL-BASED OXYGEN VACANCIES ON N-ENRICHED POROUS CARBONS FOR ENHANCED ALKALINE HYDROGEN OXIDATION AND OXYGEN REDUCTION

Redazione
by Redazione00
(AGENPARL) – LONDON (UNITED KINGDOM), mer 20 gennaio 2021 In attempt to boost the commercialization of hydrogen fuel cells with hydroxide-exchange membrane, a cost-efficient Ni/NiO/N-doped porous carbon (NC) catalyst with sufficient Ni/NiO heterojunction was fabricated by fine calcinating Ni-based metal-organic framework precursor. This in-situ carbonization not only promotes the development......

ZIF-DERIVED “SENBEI”-LIKE CO9S8/CEO2/CO HETEROSTRUCTURAL NITROGEN-DOPED CARBON NANOSHEETS AS BIFUNCTIONAL OXYGEN ELECTROCATALYST FOR ZN-AIR BATTERIES

Redazione
by Redazione02
(AGENPARL) – LONDON (UNITED KINGDOM), mer 20 gennaio 2021 Rational design and construction of efficient and robust non-noble metal bifunctional oxygen electrocatalysts is of critical significance, due to the given attention for reversible metal-air batteries. In this paper, we reported a novel two-dimensional “senbei”-like Co9S8/CeO2/Co-NC nitrogen-doped carbon nanosheets (Co9S8/CeO2/Co-NC) derived......

THE OXA-MICHAEL REACTION IN THE SYNTHESIS OF 5- AND 6-MEMBERED OXYGEN-CONTAINING HETEROCYCLES

Redazione
by Redazione02
(AGENPARL) – LONDON (UNITED KINGDOM), mar 19 gennaio 2021 The oxa-Michael reaction (OMR) offers the most effective and straightforward route to the synthesis of wide range of 5- and 6-membered oxygen-containing heterocycles including tetrahydropyrans, tetrahydrofurans, 1,4 dioxanes, isoxazolidines, isoxazolines, γ-lactones and related γ-butenolides. These molecular frameworks are common structural motifs......

SYNTHESIS OF NOVEL π-EXTENDED D–A–D-TYPE DIPYRIDO[3,2-A:2’,3’-C]PHENAZINE DERIVATIVES AND THEIR PHOTOSENSITIZED SINGLET OXYGEN GENERATION

Redazione
by Redazione00
(AGENPARL) – LONDON (UNITED KINGDOM), mar 12 gennaio 2021 Electron donor–acceptor–donor (D–A–D) π-conjugated molecules based on dipyrido[3,2-a:2’,3’-c]phenazine (dppz) were developed as photosensitizers for singlet oxygen generation. These dppz derivatives showed electronic absorption assigned to an intramolecular charge transfer transition in the red region at a wavelength of around 600 nm.......

SUSTAINABLE, SELF-CLEANING, TRANSPARENT, AND MOISTURE/OXYGEN-BARRIER COATING FILM FOR FOOD PACKAGING

Redazione
by Redazione015
(AGENPARL) – LONDON (UNITED KINGDOM), gio 07 gennaio 2021 Plastic packaging effectively protects food from mechanical, microbial, and chemical damage; however, oxygen and moisture permeate these plastics and spoil the food. Thus, the gas barrier function is usually imparted through metallic or halogenated polymeric coatings. However, the former blocks visible......
