Phase‐Engineered CuS on rGO Nanoflowers Directs Selectivity From Formate to Ethanol

open access: yesChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Copper sulfide nanoflowers grown on reduced graphene oxide undergo a phase transition to metastable digenite (Cu7.2S4), enabling efficient CO2 electroreduction. The optimized catalyst achieves 82% Faradaic efficiency for formate, while tuning rGO content shifts selectivity toward ethanol.

Safe and Localized Lentiviral Gene Delivery via Injectable Mesoporous Scaffolds for Potent Antitumor Immunity

open access: yesAdvanced Materials, Volume 38, Issue 25, 4 May 2026.
This work introduces an injectable mesoporous silica rod scaffold that confines lentiviral vectors to the injection site, enabling localized dendritic cell recruitment and transduction. The platform sustains antigen expression, promotes robust T‐cell activation, and enhances antitumor immunity.

CNC–PNIPAM Drug Delivery System Improves Endometrial Receptivity via Natural Killer Cell Immune Tolerance in Endometriosis

open access: yesAdvanced NanoBiomed Research, Volume 6, Issue 5, May 2026.
An injectable CNC–PNIPAM hydrogel is developed for intrauterine co‐delivery of levonorgestrel and botropase. This platform reprograms uterine natural killer cells toward an immune–tolerant phenotype and enhances endometrial receptivity marker expression. The results demonstrate a promising strategy to counteract endometriosis–associated infertility and

Testing eDNA Sampling Approaches in Tropical Waterways for Citizen Science and Conservation Applications

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Citizen science is increasingly popular but requires training and modifications to sampling procedures so that volunteer‐collected environmental DNA (eDNA) samples can be included in biodiversity surveys. In this study, we optimised methodology for a citizen science project targeting fish taxa; ensuring simple, safe and effective eDNA sampling.

Catalytic Conversion of Lower Olefins to Aromatics Using Zeolite‐Based Catalysts

open access: yesChemCatChem, Volume 18, Issue 9, 14 May 2026.
Zeolite‐catalyzed upgrading of light olefins (C2–C4) into benzene, toluene, and xylenes (BTX) represents a sustainable route to aromatics. This review outlines thermodynamic and mechanistic aspects, the influence of acidity and textural properties of catalysts.

Genetic Diversity, Population Structure, and Environmental Influences in Nepeta glomerulosa: Implications for Conservation in the Irano‐Turanian Region

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Nepeta glomerulosa shows moderate genetic diversity with three main clusters and significant admixture, highest in the Alborz Mountains, suggesting it may be the center of origin. High genetic differentiation (Gst = 0.4199) points to limited gene flow and possible self‐pollination, with geographic isolation shaping population structure.

Genetic Diversity, Population Structure and Evidence of Genetic Bottleneck in Geoffroea decorticans (Fabaceae): Implications for Conservation

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We documented genetic variation, population structure, and bottleneck signals in Geoffroea decorticans (Fabaceae) populations across the Atacama Desert and emphasize the urgency of genetic monitoring. Conservation plans should prioritize populations based on genetic information including those with low diversity, strong bottleneck signals and high ...

Drivers of Intraspecific Trait Variation and Drought Response of a Dominant US Great Plains Grass: Disentangling the Role of Climate and Genetic Background

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study explores how climate and genetics drive intraspecific trait variation (ITV) and drought responses in Andropogon gerardi, a dominant grass shaping North American prairies. We found that precipitation strongly predicts genetically based trait differentiation, with dry‐origin populations showing drought resilience and wet‐origin populations ...

Extensive Pollen Flow and Historical Population Expansions Shaped the Phylogeographic Pattern of Choerospondias axillaris: Evidence From Chloroplast DNA and ITS Sequences

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
MaxEnt‐based predictions reveal dramatic range dynamics of Choerospondias axillaris during Quaternary climate cycles, including northward expansion during the last interglacial, southward contraction into fragmented refugia during the last glacial maximum, and subsequent northward recolonization since the post‐glacial period.
