Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Exothermicity during the pyrolysis of large wood particles

Fuel Processing Technology
In addition to conventional pyrolysis processes, pyrolytic decomposition also plays a major role in gasification and combustion. In all of these thermochemical conversions, biomass particles of varying sizes are used.

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Density Functional Theory Calculations of the Effect of Oxygenated Functionals on Activated Carbon towards Cresol Adsorption

Surfaces, 2022
The mechanism of adsorption of p-cresol over activated carbon adsorbent and the specific role of oxygen functional groups on cresol adsorption were studied using density functional theory (DFT) calculations.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Performance evaluation of a novel two-stage waste wood gasifier: Influence of steam-to-biomass ratio and in-situ steam generation on tar formation

Fuel Processing Technology
The shift from high-quality woodchips to low-quality feedstocks increasingly shapes biomass gasification. Small- to medium-scale plants face challenges from heterogeneous feedstock and tar formation, with a research gap in producing energetically useable

Synergistic Optimization of Double Layer Capacitance and Pseudocapacitance of Activated Carbon by Nickel Oxide Loading

International Journal of Electrochemical Science, 2019
Low concentration basic nickel carbonate is selected to load nickel oxide on sargassum-based activated carbon to improve the gravimetric capacitance of activated carbon electrode materials. Based on the pyrolysis characteristics of basic nickel carbonate,
