Genetic diversity and population structure of pedunculate oaks (Quercus robur) in Wytham Woods

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Genetic diversity underpins forest resilience and adaptation, yet centuries of human activity have reshaped woodland ecosystems worldwide. We studied the population genetics of pedunculate oaks (Quercus robur) in Wytham Woods, UK, across stands with different ages and management histories.

Photo‐Gain Effect in κ‐Ga2O3 UV‐C Photoresistors Induced by Trapping of Photogenerated Holes

open access: yesphysica status solidi (b), EarlyView.
The “photo‐gain effect” amplifying the DC photocurrent of κ‐Ga2O3 UV‐C photoresistors is analyzed by means of 2D numerical simulations and linked to the capture of photogenerated holes by deep donor levels, probably associated with oxygen vacancies.

Development of a Grasshopper‐Leg‐Inspired Back‐Type Exoskeleton for the Reduction of Muscle Activation During Stoop Activities

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Farmers frequently suffer from musculoskeletal disorders, particularly lower back pain (LBP), mainly due to occupational ergonomic factors such as repetitive stooping and lifting. This study proposes using an exoskeleton to reduce LBP risk by providing external torque to the hip joints.

Designing High‐Rate and High‐Capacity Lithium Metal Anodes: Unveiling Critical Role of Carbon Nanotube Structure

open access: yesSmall, EarlyView.
This study reveals that the intrinsic structure of carbon nanotubes (CNTs), rather than chemical modifications, determines Li‐metal anode performance. With careful selection of CNTs based on their structural characteristics, a mesoporous Li host delivered an ultrahigh capacity (90 mAh cm−2), exceptional cycling stability (>2000 cycles), and outstanding

Strategic Spatial Segregation in Silicon Photoelectrodes: Decoupling Catalytic and Optical Functions for High‐Efficiency Solar Water Splitting

open access: yesSmall Structures, Volume 6, Issue 5, May 2025.
A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...

Vancomycin‐Modified DNA Origami Nanostructures for Targeting Bacterial Pathogens

open access: yesSmall Structures, EarlyView.
Applications of DNA origami nanostructures in pathogen detection and antimicrobial drug delivery require their efficient and robust binding to bacterial cells. Here, the cell wall‐binding glycopeptide antibiotic vancomycin is conjugated to selected staple strands and displayed in multivalent arrangements on the DNA origami surface to facilitate the ...

Progress towards a monophyletic Ozothamnus (Asteraceae: Gnaphalieae)

open access: yesTAXON, EarlyView.
Abstract The Cassinia clade (Asteraceae: Gnaphalieae) is a predominantly shrubby group of ca. 100 species occurring in Australia and New Zealand. Most species are currently placed in the large genera Cassinia and Ozothamnus, and their various satellite genera comprise between one and five species each.
