Carbon neutrality refers to the state of making net‐zero emissions carbon dioxide (CO 2 ), which is a key concept in tackling global warming. It can be achieved by offsetting as well balancing reduced and emitted emissions. Globally, CO mainly from fossil fuel power plants. The use capture storage technology, including pre‐, post‐, oxy‐fuel combustion capture, plants provide carbon‐neutral stra...

Bi4V2O11 was prepared via a one-pot solvothermal method and characterized via XRD, Raman, XPS, Electrochemical impedance spectroscopy. The as-prepared Bi4V2O11 sample displays excellent photocatalytic activity towards oxygen evolution under light irradiation. The hierarchical structure is in favour of the spatial separation of photogenerated electrons and holes. Furthermore, the internal polar ...

Multiple functional ionic and electronic orders are observed in high temperature superconducting cuprates. The static charge density wave order is one of them and it is spatially localized in different spatial regions of the material. It is also known that the oxygen interstitials introduced by chemical intercalation self-organize in oxygen rich space in the spacers and hole rich space in the C...

We recall that hydrogen combustion does resolve the environmental problems of fossil fuels due to excessive emission of carcinogenic substances and carbon dioxide. However, hydrogen combustion implies the permanent removal from our atmosphere of directly usable oxygen, a serious environmental problem called oxygen depletion, since the combustion turns oxygen into water whose separation to resto...

Abstract We enhance the treatment of crystallization for models white dwarfs (WDs) in stellar evolution software Modules Experiments Stellar Astrophysics (MESA) by implementing carbon–oxygen (C/O) phase separation. The separation process during leads to transport oxygen toward centers WDs, resulting a more compact structure that liberates gravitational energy as additional heating modestly slow...

The article is devoted to the analysis of flame anchoring mechanism in test case MASCOTTE C-60 RCM2 on supercritical hydrogen/oxygen combustion at 60 bar, with transcritical (liquid) injection oxygen. simulated by means in-house parallel code HeaRT three-dimensional LES framework. cubic Peng–Robinson equation state its improved translated volume formulation assumed. Diffusive mechanisms and tra...

background low-cost anaerobic sequencing batch reactor (asbr), which is widely used for controlling high-organic wastewater, is an effective method to remove chemical oxygen demand (cod). objectives the main objectives was evaluating the feasibility of using asbr in the treatment of synthetic dairy wastewater, determining its removal efficiency, and assessing the effect of temperature on operat...

Water oxidation (i.e., oxygen evolution) reaction is the most often used, green anodic pair of carbon dioxide (CO2) electroreduction, mimicking natural photosynthetic process. At same time, it requires high energy input and generates a product little commercial value oxygen). Finding appropriate alternative anode processes to be coupled with CO2 reduction major undertaking. Several factors need...

The very large reserves of methane, which often are found in remote regions, could serve as a feedstock for the production of chemicals and as a source of energy well into the 21st century. Although methane currently is being used in such important applications as the heating of homes and the generation of hydrogen for ammonia synthesis, its potential for the production of ethylene or liquid hy...

The evolution of white dwarfs is essentially a cooling process that depends primarily on the energy stored in their degenerate cores and on the transparency of their envelopes. In this paper we compute accurate cooling sequences for carbon–oxygen white dwarfs with hydrogen dominated atmospheres for the full range of masses of interest. For this purpose we use the most accurate available physica...
