From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

open access: yesAdvanced Materials, EarlyView.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

Methane in deep sea hydrothermal plumes. Development of a new in-situ methane sensing technology [PDF]

open access: yes, 2008
Information on the concentration and distribution of dissolved methane (CH4), together with other geochemical tracers, in real time is of great value in detecting, monitoring, and understanding the functioning of hydrothermal plumes.

Vertical distribution of methane oxidation and methanotrophic response to elevated methane concentrations in stratified waters of the Arctic fjord Storfjorden (Svalbard, Norway) [PDF]

open access: yes, 2013
The bacterially mediated aerobic methane oxidation (MOx) is a key mechanism in controlling methane (CH₄) emissions from the world’s oceans to the atmosphere.

Decoupling Activation and Preservation: Architectural Design Principles of Organic Frameworks for Selective Photocatalytic Methane Oxidation

open access: yesAdvanced Materials, EarlyView.
Selective methane (CH4) photooxidation emerges from architectural decoupling of activation and preservation. Programmable organic semiconductor frameworks spatially organize oxidative flux and intermediate residence, separating reaction zones from product domains to synchronize activation strength with stabilization and establish a selective oxidation ...

Methane to Liquid Fuels over Metal Loaded HZSM-5 Catalyst [PDF]

open access: yes, 2011
ZSM-5 zeolite is an acidic catalyst that is highly potential for the conversion of natural gas to liquid fuels. One of the variables that controls the acidity of the ZSM-5 is its Si/Al ratio.

De-oxygenation of CO2 by using Hydrogen, Carbon and Methane over Alumina-Supported Catalysts [PDF]

open access: yes, 2012
The de-oxygenation of CO2 was explored by using hydrogen, methane, carbon etc., over alumina supported catalysts. The alumina-supported ruthenium, rhodium, platinum, molybdenum, vanadium and magnesium catalysts were first reduced in hydrogen atmosphere ...

Effect of a Combination of Phytogenic Compounds on In Vitro Rumen Fermentation Parameters and In Vivo Lactation Performance and Methane Emissions in Dairy Cows

open access: yesMethane
An in vitro and an in vivo study were conducted to investigate the effects of a blend of cinnamaldehyde, eugenol, and capsicum oleoresin (CEC) on rumen fermentation parameters, animal performance, and methane (CH4) emissions in dairy cows.
