Selectivity in Tip-Induced Skeletal Editing via Heteroatom Substitution

Abstract Skeletal editing enables precise structural modifications of molecules at late stages of a synthetic sequence. We recently demonstrated skeletal editing on a single-molecule scale. Voltage pulses applied by the tip of a scanning probe microscope to an oxygen-containing s...

Synthesis of N-A-S-H Gels via Sol–Gel and Hydrothermal Methods: Composition, Microstructure, and Dynamic Adsorption Characteristics for Sr2+

Fly ash-based geopolymers are widely used as solidification matrices for intermediate- and low-level radioactive waste liquids. Their performance relies heavily on the adsorption capacity of the primary component, N-A-S-H gels, which directly governs the long-term stability of th...

The Cold-Air Outbreaks in the Marine Boundary Layer Experiment model-observation intercomparison project (COMBLE-MIP) – Part 1: Model specification, observational constraints, and preliminary findings

Models struggle to represent the coupled microphysical, turbulent and radiative processes within widespread, long-lived marine cold-air outbreak (CAO) cloud fields, contributing to forecast and climate biases. Here we combine ground-based and satellite measurements to initialize...

Biomass Valorization Through Applications in the Continuous Removal of Iron from Water: Batch Equilibrium and Fixed-Bed Adsorption

Iron is one of the most common constituents in groundwater, and affordable decentralized options for removing residual iron remain limited. This study valorizes two abundant agro-industrial residues, sugarcane bagasse and green coconut mesocarp, as biosorbents for removing residu...

A New Product Formula for $$(z;q)_\infty $$, with Applications to Asymptotics

Abstract We express the q -Pochhammer symbol $$(z;q)_\infty $$ ( z ; q ) ∞ as an infinite product of gamma functions, analogously to how Narukawa expressed the elliptic gamma function as an infinite product of hyperbolic gamma functions. This identity is used to obtain asymptotic...

Resolving Lateral Heat Transport in GaN‐on‐SiC HEMT Structures via Transient Thermometry

ABSTRACT Understanding lateral heat transport in GaN high‐electron‐mobility transistors (HEMTs) is essential for the thermal management of high‐power and high‐frequency electronics. Here, lateral thermal transport in GaN HEMTs on 4H‐SiC is investigated using electrical thermometr...

Sensitivity of NOX formation to nitrogen release and char surface area: An estimation approach for CFD modelling of pulverized coal combustion

To effectively mitigate NO X emissions in pulverized coal combustion, Computational Fluid Dynamics (CFD) is frequently employed as a predictive tool. Because fuel-bound nitrogen is the primary source of NO X in these applications, modelling largely relies on coal characterization...

Sensing in fluidized bed processes — from capturing details to monitoring the operation

This article offers an opinion and a perspective on the future development of sensing techniques in fluidization technology. The direction of the field is exemplified by a handful of techniques, pointing at the advancements that revolve around two aspects. First, increasing the b...

Mapping the evolution of social life cycle assessment: a bibliometric and text-based SDG analysis (2010–2025)

Purpose Social life cycle assessment (S-LCA) has developed as a key methodology for evaluating social impacts across the product life cycle. However, existing bibliometric reviews remain limited in temporal coverage and analytical scope. This study aims to provide a broad, up-to-...

HierX: Fast multi-scale distance-decay interaction on million-node networks

Abstract Many models across the sciences require global distance-decay interactions on large sparse networks. Gravity models, accessibility measures, spatial economic models, and network influence processes all evaluate distance-weighted potential fields: each location accumulate...

A review of selected Swedish contributions to instrumentation at neutron scattering facilities

Abstract The European Spallation Source in Lund, Sweden, is the next generation neutron research facility that will provide unprecedented capabilities for particle physics as well as materials and life science research through its high brightness, long-pulse neutron source and ad...

Ultra-fast spin Hall nano-oscillator based microwave spectral analysis

Abstract Ultra-fast spectrum analysis based on rapidly tuned spintronic nano-oscillators has been under development for the last few years and has already demonstrated promising results. Here, we demonstrate an ultra-fast microwave spectrum analyzer based on a chain of five mutua...

Diamondiyne: A 3D Carbon Allotrope With Mixed sp–sp 3 Hybridization

ABSTRACT The creation of carbon allotropes is synthetically highly challenging, but their practical significance to science and technology cannot be underestimated. Here, we report the synthesis of a new carbon allotrope, diamondiyne, which is the second known one (after diamond)...

Star cluster formation from turbulent clumps. V. Stellar clustering around massive stars

Abstract Massive stars (≥8 M⊙) are known to have high degrees of multiplicity, e.g., with about 60% in triples or higher-order multiples. Such high levels of multiplicity may arise during formation (primary multiplicity) or through dynamical processing of already formed stars in...

The Relationship between Human Values, Job Satisfaction, and Well-being among Thai IT Employees in Thailand: An Exploratory Study

Quantifying non-Markovianity in magnetization dynamics via entropy production rates

Abstract Magnetization dynamics is commonly described by the stochastic Landau-Lifshitz-Gilbert (LLG) equation. However, on picosecond timescales, inertial and open-system extensions of the LLG equation are necessary to interpret recent experiments. While it has been anticipated...

Self-Assembling Hole-Transport Molecules Enable Photomultiplication-Type Organic Photodetectors with High Detectivity and Enhanced Environmental Stability

Photomultiplication-type organic photodetectors (PM-OPDs) have attracted significant attention for their high gain and simplified device architecture. However, their practical application is severely constrained by the high dark current density inherent to charge injection-type m...

Coupling fiber cationization with hygroplasticization for 3D-formable cellulose-based materials

Thanks to their high availability, renewability, and degradability, paper-based materials are promising candidates for partial replacement of less sustainable fossil-based products. A disadvantage of conventional paper is, however, its low strainability and restricted shapeabilit...

Increasing risk of vapor pressure deficit exceeding critical thresholds for tree growth

With global warming, rising atmospheric vapor pressure deficit (VPD) has emerged as a critical driver of vegetation productivity and the terrestrial carbon sink. Yet, the thresholds beyond which VPD constrains tree growth remain poorly quantified. Using 2,953 tree-ring sites and...

The Water-Sediment Regulation Scheme Drives Phytoplankton Dynamics in the Yellow River Estuary

The Water-Sediment Regulation Scheme (WSRS) of the Yellow River is a large-scale anthropogenic intervention designed to alleviate downstream channel siltation, yet its long-term ecological effects on estuarine phytoplankton communities remain contentious. Based on a 12-year (2011...
