As the global carbon crisis worsens, we need the technology which can evolve from capturing carbon to efficiently using it. Dielectric barrier discharge (DBD) systems under mild conditions, a type of non-thermal plasma (...

Fuel Cell Recreational Vehicles (FCRVs) are emerging as a promising sustainable alternative to conventional diesel- and gasoline-powered recreational vehicles. This paper evaluates the financial and technological aspects...

Today’s main topic is global warming and carbon neutrality. We therefore investigate biofuel (Bio-Energy) in our living space; its amount is comparable to fossil fuel. We analyze the production of hydrogen by processin...

Abstract Herein, Ru⁰/TiO₂ nanocomposites containing 0.5 wt% Ru were prepared via a simple wet-impregnation route followed by chemical reduction and were thoroughly characterized by XRD, FTIR, SEM, TEM, and EDS analys...

H2 rich gas produced from Scenedesmus almeriensis biomass residue after lipidic extraction by low temperature catalytic gasification is addressed. The pyrolysis-gasification behavior under different atmospheres (CO2/He, ...

The large-scale integrated hydrogen production model has become an important way to solve the problem of the “wind and solar curtailment” and promote the development of hydrogen energy industry. Whether it is pure wa...

The high population growth rate, the accelerated industrialization and unpredictability of oil prices in the world have considerably raised the energy demand which has enhanced the necessity of alternative and sustainabl...

Abstract Background The residential building sector is a major contributor to Germany’s greenhouse gas emissions. Over 60 % of the energy used for space and domestic hot water heating comes from fossil fuels sources a...

Ammonia/diesel blended fuel significantly reduces carbon emissions, but it has issues such as high unburned ammonia emissions and low combustion efficiency. To achieve the goals of carbon peak and carbon neutrality, this...

This study investigates two NOx-mitigation strategies, namely exhaust gas recirculation (EGR) and water–diesel emulsification, in a diesel–hydrogen dual-fuel compression ignition engine. A validated three-dimensional...

Hydrogen technology is significantly influencing the transformation of the energy sector, supported by recent advancements in global infrastructure. The production of sustainable hydrogen is contingent upon the developme...

Solar iron production from H2-based direct reduction of iron ore was investigated in a continuously particle-fed reactor for performance analysis. Concentrated solar energy was used as the external source of high-tempera...

Hydrogen is widely recognized as a clean and sustainable energy carrier, driving the urgent need for safe and efficient solid-state storage materials. In this study, the structural, thermodynamic, electronic, optical, an...

The Sb3+ doping strategy has been proven to be an effective way to regulate the band gap and improve the photophysical properties of organic-inorganic hybrid metal halides (OIHMHs). However, the emission of Sb3+ ions in ...

The paper presents a simple one-step "green" approach to the synthesis of magnetite nanoparticles. The magnetite nanoparticles were synthesized using fruit extract obtained from grape peels and grape pulp. The formation ...

We show how a theory for electrocatalysis developed in our group can be combined with density-functional theory in order to obtain free-energy surfaces for electrochemical reactions. The combined theory is applied to the...

Nearly Zero Energy Buildings (NZEBs) are pivotal in addressing the escalating energy and environmental challenges of hot climates, where extreme cooling demands and reliance on fossil fuels intensify carbon footprints. T...

In this work, we report the synthesis and characterization of iron oxide nanoparticles supported in nanostructured carbon (CMK-3). This material is promising in the application of hydrogen adsorption for energy storage. ...

Abstract This study presents a comprehensive thermodynamic, economic, and environmental assessment of a novel biomass-fueled tri-generation system designed to simultaneously produce electricity, hydrogen, and desalinated...

Nickel borides doped with elements of first transition series (Cr, Mn, Fe, Co, Cu, and Zn) MNiB, 4% (w/w) respect to Ni, and prepared with the same method as NiB, were used in the glucose and the nitrobenzene hydrogenati...

Abstract The practical implementation of lithium metal batteries is hindered by unstable electrode-electrolyte interfaces and sluggish ion transport kinetics. Here, we report a molecular design strategy that remodels ele...

Abstract The dual pressures of climate change and industrial water scarcity demand integrated solutions that jointly decarbonize power supply and reduce freshwater dependency. This study presents a site-specific, techno-...

Abstract Current paradigms for the origin and evolutions of life and the environment on early Earth have been based on the premises that carbon dioxide (CO2) and nitrogen gas (N2) were the principal constituents of the a...
