Hydrogen is produced by water electrolysis, steam methane reforming, methane pyrolysis and coal gasification. We compare the environmental impact of hydrogen production routes by life cycle analysis. Hydrogen is used in power systems, transportation, hydrocarbon and ammonia production, and metallugical ...
Using microorganisms to degrade bioplastics is a promising strategy for reducing non-degradable plastic waste. However, maintaining bacterial viability and activity during culture and storage remains challenging. With the use of conventional methods, cell viability and activity was lost; therefore, these ...
Production of a storage cell of a storage cell field in a semiconductor memory comprises etching parallel trenches in semiconductor substrate, forming a bar made from the material of substrate, and further processing. Production of a storage cell of a storage cell field in a semiconductor memory ...

However, the majority of the proposed systems require on-demand de-novo DNA synthesis techniques that produce a large amount of toxic waste and therefore are not industrially scalable and environmentally friendly. Inspired by the architecture of semiconductor memory devices and recent developments in ...
In 2021, Yong et al. investigated the contact angle of water in a CH4/CO2/graphite system at a temperature of 300 K and a pressure of 5.36 MPa. Accordingly, with the increase in CO2concentration, while all systems had weak gas-wet properties, the water contact angle increased119. ...
The access to abundant and cheap energy has been mankind's most essential foundation of economic prosperity. Fossil fuels, which have been the main energy resources in the last two centuries, have supported the progress of human civilization and economic development [1]. However, the finite nature...
Coffee is among the most drunk beverages in the world and its consumption produces massive amounts of waste. Valorization strategies of coffee wastes inclu
materials are high volumetric or gravimetric energy density, high cyclability, no pyrolysis, the feasibility of low-temperature charge to utilize low-grade waste heat, small hysteresis, fast reaction rate, fast reactant transport, heat conduction, fast water penetration in case of using water, etc....
The detection and enumeration of indicator bacteria such as Escherichia coli is used to assess the extent of faecal contamination of drinking water. On the basis of this approach, the effectiveness of storing water contaminated with faecal indicator bacteria in brass or earthern vessels (mutkas) of...
