Dry Reforming of Biogas Over Li–Ni–Al Catalysts: Influence of Li Incorporation Method

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Hydrogen is a promising source of energy, given the current context of depletion of fossil fuels and increased emissions of greenhouse gases. The technological route for obtaining this fuel from the dry reforming of biogas has received considerable attention from researchers, as it converts the polluting gases CH4 and CO2 into synthesis gas ...

Changes in phenolic profile, physicochemical properties and sensory attributes of steamed bread fortified with golden kiwifruit (Actinidia chinensis) flour during processing

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Chinese steamed bread (CSB) is a traditional East Asian staple. Its texture and nutrition depend on the gluten and starch content of the wheat flour that it contains. Incorporation of golden kiwifruit, which is rich in dietary fiber, vitamin C, and phenolic antioxidants, offers a novel fortification strategy.

Toward Efficient and Reliable Chemical Upgrading Using Solid Oxide Electrochemical Reactors, Mechanisms, Challenges, and Design Principles

Small, EarlyView.
Solid oxide electrochemical reactors (SOERs) offer a compelling pathway for coupling renewable electricity with chemical manufacturing, but their real application is still limited by low efficiency and instability. This review systematically summarizes SOER reaction mechanisms, performance‐limiting factors, and recent progress toward high‐efficiency ...

Investigating the Iron‐Steam Process for Coupling With SOEC and SOFC: A Step Toward Integrated Hydrogen and Electricity Storage

steel research international, EarlyView.
Fixed‐bed reactor experiments (10 L) validate the iron–steam redox process, bridging material‐scale research and industrial power‐to‐power applications. Coupled with SOEC/SOFC systems, this framework defines critical interfaces for heat and gas management. Results confirm reproducible hydrogen storage and release, demonstrating technical feasibility at

Awareness–Action and Policy Acceptability in Mitigating Greenhouse Gas Emissions: Key Stakeholders in Germany's Cattle Dairy and Meat Chains

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper presents a systematic literature review and targeted searches to define a synthesis framework mapping the awareness–action gap, progression along the awareness–action continuum and policy acceptability in greenhouse gas (GHG) emissions mitigation among key stakeholders in Germany's cattle dairy and meat chains.

The effect of heavy tars (toluene and naphthalene) on the electrochemical performance of an anode-supported SOFC running on bio-syngas

, 2018
The effect of heavy tar compounds on the performance of a Ni-YSZ anode supported solid oxide fuel cell was investigated. Both toluene and naphthalene were chosen as model compounds and tested separately with a simulated bio-syngas. Notably, the effect of
