Recent developments in the use of activated charcoal in medicine

open access: yesJournal of Medical Science, 2022
One of the raw forms of graphite is activated charcoal which has an extensive surface area allowing for the adsorption of a wide range of chemicals. It possesses the strongest physical adsorption forces of the available materials, as well as the largest

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

On the area of surfaces [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1919
Abstract The necessary and sufficient condition that a curve should possess a length, this length being given by the usual integral formula, is well known. The curve being defined by the equations x = x(u), y = y(u), the condition is that x(u) and y(u) should be expressible as integrals with respect to u. It may seem scarcely credible

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Trade-offs and synergies between ecosystem services on the Tibetan Plateau

open access: yesEcological Indicators
Ecosystem services (ESs) are the cornerstone of human well-being. On the Tibetan Plateau and in its subregions, understanding the effects of the spatiotemporal continuity in the trade-offs/synergies of ESs, and identifying their drivers, is crucial for ...

Research on measurement of specific energy of crushing based on particle compression experimen

open access: yesMeikuang Anquan, 2022
In order to better characterize the strength characteristics of coal, according to P. R. Rittinger’s new surface theory, a determination method of specific energy of crushing based on particle compression experiment is proposed. Based on this method, the

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Changes in global carbon use efficiency in the 21st century and the potential controlling factors

open access: yesEnvironmental Research Letters
Extensive studies have demonstrated the spatiotemporal changes in carbon use efficiency (CUE) and its driving factors over the past three decades. However, how the global CUE will change and to what extent the CUE is affected by the dominant factor in ...

Electrodeposition of High-Surface-Area IrO2 Films on Ti Felt as an Efficient Catalyst for the Oxygen Evolution Reaction

open access: yesFrontiers in Chemistry, 2020
Under acidic conditions, IrO2 exhibits high catalytic activity with respect to the oxygen evolution reaction (OER). However, the practical application of Ir-based catalysts is significantly limited owing to their high cost in addition to the scarcity of ...
