Solar Fuels Via Methane Valorization: Thermochemical Pathways, Unified Metrics, and Techno‐Economic Perspectives

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A first‐of‐its‐kind review benchmarks three solar methane valorization pathways with unified performance metrics for clean fuel production. Meeting global climate targets and sustainable energy demands requires carbon‐neutral fuels and innovative conversion pathways.

From Phosphinimines to Four‐Membered SiCPN Cations: Insights Into N–Si Bonding and Ring Strain

European Journal of Inorganic Chemistry, EarlyView.
Sterically tuned N‐silyl phosphinimines enable four‐membered SiCPN cations. Hydride abstraction yields cyclic cations for Me and iPr substituents at silicon, while tBu gives a protonated intermediate. Multinuclear NMR spectroscopy, X‐ray crystallography, thermochemical density functional theory investigations, and natural bond orbital analyses reveal ...

Zero emission heating with calcium oxide and water: development and demonstration of first pilot scale thermochemical heating system for buildings

Frontiers in Energy Research
Heat supply for residential buildings is still mainly based on fossil fuels and is thus a significant contributor to CO2 emissions. Renewable heating remains a technological challenge, often for the reason that during cold weather periods heat demand ...

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Exergy‐Based Simulation and Optimization of Multiagent MSW Gasification for Sustainable Energy Recovery Using Aspen Plus

Energy Science &Engineering, EarlyView.
ABSTRACT Thermochemical gasification is one of the most efficient methods for producing solid waste synthesis gas. Therefore, to predict and analyze the process of gasification of municipal solid waste (MSW) in a downdraft fixed‐bed gasification reactor with a thermal capacity of 2.1 kW, a comprehensive numerical modeling approach based on Gibbs free ...

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures

A Bibliometric‐Based Review of Biochar for Salt‐Affected Soil Restoration: Mapping Research Trends and Future Directions

Land Degradation &Development, EarlyView.
ABSTRACT In recent years, biochar has been studied for its range of applications. Recognized by the IPCC as a key Carbon Dioxide Removal (CDR) strategy, it also stands out as an important tool for reclaiming degraded lands, including vast global areas affected by salinity, such as those in China, India, and Australia.
