Multifunctional Binding Interface Drives Near-Unity CO Selectivity in Acidic CO Electrolysis.

Angew Chem Int Ed Engl

September 2025

Department of Chemical and Biomolecular Engineering, Johns Hopkins University, Baltimore, Maryland, 21218, USA.

The electrocatalytic carbon dioxide (CO) reduction is challenged by the parasitic hydrogen evolution reaction (HER) especially in acidic media. Here, we elaborate that redox-active isoindigo, acting as a multifunctional co-catalyst, can pre-activate CO-bound intermediates and suppress HER upon the synergistic effects of Lewis acid-base adduct formation, intramolecular hydrogen-bond interaction, and interfacial water structure modulation. Modifying a silver catalyst with isoindigo substantially decreases the energy barrier for CO-to-*COOH conversion, which is regarded as the potential-limiting step of carbon monoxide production.

Intracellular vesicular transport by kinesin-1 motors through numerous 3-dimensional (3D) microtubule (MT) intersections must be regulated to support proper vesicle delivery. Knowing kinesin-1 can be regulated via autoinhibition, does kinesin-1 exhibit autoinhibition on cargo, and could this regulate vesicular transport through 3D MT intersections in vitro? To answer this question, we compared liposome transport by ∼10 nearly full-length kinesin-1 motors with KLC bound (KinΔC) versus constitutively active control (K543). In 3D MT intersections, KinΔC-liposomes terminate (48%), go straight (43%), but rarely turn (9%), starkly contrasting K543-liposomes which go straight (57%), turn (31%), but rarely terminate (12%).

Introduction: People with schizophrenia (SZ) display neurocognitive deficits that have been identified as predictors of poor functioning and disability. Previous reports have noted that these deficits are strikingly similar to the cognitive sequalae of poor sleep. Consistent with this observation, extensive animal and basic human research have strongly support the deleterious effects of poor sleep on neurocognition.

It is widely recognized that reciprocal interactions between cells and their microenvironment, via mechanical forces and biochemical signaling pathways, regulate cell behaviors during normal development, homeostasis and disease progression such as cancer. However, how exactly cells and tissues regulate growth in response to chemical and mechanical cues is still not clear. Here, we propose a framework for the chemomechanical regulation of growth based on thermodynamics of continua and growth-elasticity to predict growth patterns.

Genome-wide spatial long-read approaches often lack single-cell resolution and yield limited read lengths. Here, we introduce spatial ISOform sequencing (Spl-ISO-Seq), which reveals exons and polyadenylation sites with near-single-cell resolution. Spl-ISO-Seq selects long cDNAs and doubles to triples read lengths compared to standard preparations.

is a major human pathogen, mostly infecting people with pre-existing lung conditions, such as cystic fibrosis. The production of glycopeptidolipids (GPL) is a major determinant of virulence of this bacterium, with clinical isolates that lack GPL generally exhibiting more aggressive clinical behavior. The current paradigm is that GPL production is abolished via irreversible, spontaneous mutations taking place as part of in-host evolution.

Repeated exposure to stimuli elicits decreasing sensory neural responses over time (adaptation). However, resulting behavioral responses can either weaken over time (habituation) or remain invariant, indicating that the neural-behavioral link is not fixed. To investigate neural adaptation and its flexible translation into behavioral decision making, we created a mathematical framework hypothesizing (1) that sensory networks optimize the speed and accuracy of encoding exogenous stimuli, and (2) that representations form along two time scales, one embedding immediate information and the other stimulus history.

The discovery of thousands of exoplanets and the emergence of telescopes capable of exoplanet atmospheric characterization have intensified the search for habitable worlds. Due to selection biases, many exoplanets under study are planets deemed inhospitable because their surfaces are too warm to support liquid water. We propose that such planets could still support life through ionic liquids: Liquid salts with negligible vapor pressure that can persist on warm planets with thin atmospheres, where liquid water cannot.

Langmuir

August 2025

Department of Civil, Environmental and Architectural Engineering, Worcester Polytechnic Institute, Worcester, Massachusetts 01609-2280, United States.

This study explored a sustainable method for depositing carbon-based coatings on Ni-Invar and Ti-6Al-4V metallic substrates using a pack carburization process with cyanide-rich (cassava) leaves as the carbon source. Comprehensive experimental and computational analyses were performed to investigate the composition, structure, and tribological performance of the coatings. Characterization using X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, scanning electron microscopy (SEM), and lateral force microscopy (LFM) revealed that the Ni-Invar substrate developed turbostratic multilayer graphene coatings with minimal carbide formation, achieving ultralow coefficient of friction (COF) values of 0.
