Tuning Second-Sphere Amine Basicity to Modulate Hydride Intermediates and Selectivity in Molecular Manganese Bipyridine CO2 Electroreduction

Abstract Manganese bipyridine tricarbonyl complexes represent a prominent class of molecular electrocatalysts for efficient and selective CO2-to-CO conversion. Recent efforts have sought to redirect product selectivity toward HCOOH by incorporating second-sphere amine proton rela...

Comparison of synthetic and post-synthetic molecular genetic methods of reducing xylan glucuronidation in hybrid aspen for biorefinery applications

Abstract Background The pattern of xylan backbone substitution by 4- O -methylglucuronic acid (mGlcA) and O -acetyl groups generated during biosynthesis in the Golgi apparatus plays a key role in molecular interactions between secondary cell wall polymers in hardwoods, thus regul...

Ultrasound velocity profiling of wood chips flow in an industrial application

Abstract Ultrasound velocity profiling (UVP) was applied to an industrial impregnation vessel containing wood chips and liquid. The method could successfully determine the velocity of the wood chips by measuring through the 15 mm thick steel wall. The measuring depth is and cover...

Design, Synthesis, and Comparative Selection Analysis of a Chemically Diverse Peptide-Like DNA-Encoded Library

Abstract DNA-encoded chemical library technology offers a cost-effective method for screening billions of compounds in a single experiment. However, achieving broad coverage of lead-like chemical space remains challenging. Here, we describe the design and synthesis of a three-cyc...

Are Unaudited Firms More Likely to Disregard Tax Payments Prior to Bankruptcy? Small‐Firm Evidence From Sweden

ABSTRACT Proponents of mandatory auditing claim that auditing reduces the risk of tax evasion and that firms disregarding tax payments distort competition because they operate with lower costs than firms that meet their tax obligations. To investigate this, we analyse data from a...

Time-lapse RESOLFT nanoscopy empowered by deep learning

Abstract Capturing the dynamic interplay of proteins and organelles within cells requires microscopy methods with high spatial and temporal resolution. Reversible Saturable OpticaL Fluorescent Transition (RESOLFT) demonstrated great potential for live cell nanoscopy by using patt...

Sequence‐Controlled Copolymers Through Selective Ring‐Opening Polymerization of Multiunit Macrolactones

ABSTRACT A new strategy for the synthesis of sequence‐controlled polymers (SCP), in which increased ester reactivity by the introduction of neighboring glycolate units within a multiunit macrolactone, was developed. DFT calculations and model reactions show that the proximity of...

Impact of climate change on the photovoltaic power potential in Sweden across 21st century

Abstract Solar photovoltaic generation strongly relies on weather conditions, which will be affected by future climate change. Traditional methods for estimating photovoltaic generation potential often overlook detailed installation factors and snow impacts, leading to inaccuraci...

Mapping motivation profiles and perceived role value appreciation in research project management

Purpose To investigate the motivational profiles of research project managers (RPMs) using self-determination theory (SDT) and explore their correlation with perceived organizational role value appreciation. Design/methodology/approach A quantitative cross-sectional online survey...

Stochastic Modeling and Resource Dimensioning of Multi-Cellular Edge Intelligent Systems

Edge intelligence enables the execution of AI inference tasks on computing platforms at the network edge, typically co-located with or near the radio access network rather than in centralized clouds or on mobile devices. This approach is particularly well suited for data analytic...

Dynamic operation of a hybrid air-driven concentrating solar thermal system based on rotary receiver and radial thermocline

Air-driven concentrating solar thermal (CST) systems can supply heat up to 800 °C for supercritical CO 2 (sCO 2 ) Brayton cycles and process heat, but their integrated transient behaviour under variable solar input and hybrid electric heating remains uncharacterised. This study d...

Plasticizer compatibility with amorphous (low-ordered) cellulose and dialcohol cellulose

Abstract Biopolymers such as cellulose are promising candidates for replacing fossil-based plastics, but their processing is often limited by their high glass transition temperature ( T g ) and strong intermolecular hydrogen bonding. Plasticizers can improve processability, yet t...

Children, Robots, and Reproducibility: A review of recent reproducibility challenges in child-robot interaction

Given the rapid advancements and shifting requirements in the field of Child-Robot Interaction (CRI), it is crucial to understand how the field is evolving and if and how researchers are adhering to current best practices. We present a review of five years (2020-2024) of CRI rese...

Mechanical control of magnetic exchange and response in GdRu2Si2

Abstract Magnetic skyrmions are nanoscale topological spin textures promising for low-power spintronics, provided their stability can be controlled. Mechanical strain modifies interatomic distances and underlying magnetic interactions, offering an efficient control route. We pres...

On the comparison principle for a nonlocal infinity Laplacian

Abstract In this article, we prove the uniqueness of viscosity solutions to ℒ ∞ ⁢ u = f in ⁢ Ω , see text \mathcal{L}_{\infty}u=f\quad\text{in }\Omega, where ℒ ∞ {\mathcal{L}_{\infty}} denotes the nonlocal infinity Laplace operator, Ω a bounded domain, and f a continuous function...

Mechanistic Origins of Selective Aromatic Amino Acid Oxidation by Mn-Doped TiO2 Nanozymes

Abstract Metal oxide nanozymes are emerging as robust redox catalysts, yet the molecular basis of their substrate selectivity and reaction pathways remains poorly understood. Here, we identify 20 mol% Mn-doped TiO2 as a nanozyme platform that selectively oxidizes aromatic amino a...

CausalCACTUS: A Causally Consistent and Context-Aware Framework for Counterfactual Explanations

Abstract Counterfactual explanations have been proposed to provide actionable insights for complex black-box classifiers by suggesting “what-if” explanations that alter undesirable prediction outcomes to desired ones. Recent advances have emphasized desirable properties such as c...
