Green Energy or Green Colonialism? The Case of Green Hydrogen in Namibia

open access: yes
Green hydrogen, promoted by institutions like the International Renewable Energy Agency and the European Union as pivotal to decarbonization, faces criticism through the lens of green colonialism. This paper argues that the energy transition often replicates neo-colonial resource extraction, particularly in Global South nations such as Namibia, where ...

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

open access: yesFEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

open access: yesFEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

Online verification of adjustable robust optimization for electric hydrogen integrated energy systems with comprehensive demand response

open access: yesInternational Journal of Electrical Power & Energy Systems
Traditional energy systems are gradually transitioning to new energy systems dominated by clean sources such as wind, solar, and hydrogen. As the penetration of renewable energy increases, the high uncertainty in their output presents significant ...

Effects of hydrogen peroxide on fungal disinfection, hatch rate and larval deformities of rainbow trout (Oncorhynchus mykiss) [PDF]

open access: yes, 2008
The hydrogen peroxide in concentrations of 500, 750 and 1000 mu l/l, malachite green with usual concentration (1.5mg/l) and natural control treatments were examined to evaluate the antifungal effects of the chemicals on Rainbow Trout eggs.

First principle study of hydrogen behavior in hexagonal tungsten carbide

open access: yes, 2010
Understanding the behavior of hydrogen in hexagonal tungsten carbide (WC) is of particular interest for fusion reactor design due to the presence of WC in the divertor of fusion reactors.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

open access: yesFEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Insights into the co-combustion attributes and mutual effects of high-alkali lignite and flotation carbon-rich fractions from coal gasification fine slag

open access: yesResults in Engineering
The reutilization of waste coal gasification fine slag (GFS) as an energy source through co-combustion technology has been demonstrated to be a more economically and environmentally viable solution.
