Unveiling Lasting Impact: A Cultural‐Historical Activity Theory Perspective on Original Participants in an Afterschool STEM Club

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT The Girls Excelling in Math and Science (GEMS) club is a long‐standing afterschool STEM program (1994–present). The study investigates the features of GEMS by exploring retrospective experiences of a group of original GEMS girls (OGGs) who attended GEMS in 1994–1995. Survey data were collected from 14 OGGs and in‐depth interview data from nine

AI‐driven discovery of feasible 3D printing configurations for metal alloys

open access: yesAI Magazine, Volume 47, Issue 3, Fall 2026.
Abstract Configuring additive manufacturing (AM) processes for metal alloys is challenging because printed output quality depends on complex interactions among process parameters such as laser power, scan speed, and feed rate. Conventional trial‐and‐error approaches are inefficient because experiments are costly and the process parameter space is ...

Plant biostimulants and their potential role in achieving the United Nations sustainable development goals

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1449-1456, September 2026.
Plant biostimulants are substances that are obtained from a variety of sources and are applied in minute quantities to enhance plant growth and vigor. In this review we detail how the use of plant biostimulants may contribute to efforts to achieving a number of the UN Sustainable Development Goals.

Strain Engineering via W–O–Ru Interfacial Coupling to Suppress Lattice Oxygen Activation for Stable Acidic Water Electrolysis

open access: yesAngewandte Chemie, Volume 138, Issue 34, 17 August 2026.
Constructing atomically coupled W–O–Ru interfacial units on RuO2 triggers a dynamic strain evolution during the oxygen evolution reaction. An initial tensile strain secures structural stability, while a self‐adjusting transition to interfacial compression optimizes catalytic activity.

Solvent‐Induced Surface Morphology Probed by NP‐SIMS

open access: yesSurface and Interface Analysis, Volume 58, Issue 9, Page 630-639, September 2026.
ABSTRACT Surface morphology, that is, roughness and molecular arrangement, is known to have an impact on secondary ion mass spectra. The present study examines this issue using nanoprojectile secondary ion mass spectrometry (NP‐SIMS). NP‐SIMS involves bombarding the analyte with individual nanoparticles resolved in space and time and recording the ...

Numerical simulation study of aluminum particle evaporation combustion process based on SPH method

open access: yesAIP Advances
A large variety of metal fuels is usually added to the modern solid rocket propellants to improve the propellant energy and motor specific impulse and to suppress high frequency unstable combustion. Among them, aluminum is the most common additive.

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space

open access: yesThe Modern Law Review, Volume 89, Issue 5, Page 723-759, September 2026.
As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

Renewing Concerns of Technical Complexity in Accidents Research: An Argument to Retain Perrow's “First Thesis”

open access: yesJournal of Contingencies and Crisis Management, Volume 34, Issue 3, September 2026.
ABSTRACT It has been 40 years since Charles Perrow published the landmark work Normal Accidents ([1984]1999), built largely on an analysis of the Three Mile Island (TMI) nuclear power plant accident. While still a highly influential framework in the study of complex systems, the status of the argument remains in flux.

Genome Manipulation in Microalgae: A Systematic Map on Improved Traits, Strains, and Their Commercial Applications

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Microalgae are promising platforms for producing diverse biocompounds relevant to multiple commercial sectors, and the use of genomic technologies in microalgae is rapidly expanding. To examine the research trends, we conducted a bibliographic analysis (systematic map) of this rapidly developing field. Our study presents a descriptive overview
