Gallium‐Catalyzed Tandem Carbonyl–Olefin Metathesis/Dehydrogenative Coupling Enables Rapid Access to Cyclopentenes

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A cationic gallium(III) catalyst enables rapid construction of substituted cyclopentenes via tandem carbonyl‐ene metathesis/Friedel–Crafts coupling. Electronic tuning of alcohol electrophiles allows access to diverse, densely functionalized rings in a single operation.

Antibacterial Hydrogel Dressing With Ca2+‐Dependent Hyaluronidase Responsiveness for Accelerating Wound Healing via On‐Demand Release of AIE Photosensitizers

open access: yesExploration, EarlyView.
This study innovates a Ca2+‐responsive hydrogel dressing that releases AIE photosensitizers on‐demand. Low Ca2+ enhances bacterial hyaluronidase (HAase) activity, degrading hyaluronic acid dressing to trigger antibacterial ROS release, while high Ca2+ inhibits HAase, preventing overdosing.

Biomagnetic of Apatite-Coated Cobalt Ferrite: A Core–Shell Particle for Protein Adsorption and pH-Controlled Release

open access: yesNanoscale Research Letters, 2011
Magnetic nanoparticle composite with a cobalt ferrite (CoFe2O4, (CF)) core and an apatite (Ap) coating was synthesized using a biomineralization process in which a modified simulated body fluid (1.5SBF) solution is the source of the calcium phosphate for

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

open access: yesFlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Biodegradable Natural Polymer‐Based Drug Delivery Systems for Bone Tissue Engineering

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT The increasing incidence of bone diseases and injuries, especially among aging populations, has underscored the shortcomings of traditional treatments such as bone grafts and metal implants, which often face complications including immune rejection, mechanical failure, and delayed healing.

Camera trap distance sampling for density estimation of tiger prey in a Sumatran ecosystem restoration concession

open access: yesWildlife Biology, EarlyView.
Estimating prey species densities is critical for implementing effective tiger Panthera tigris recovery strategies. Several statistical models exist for density estimation of unmarked species from camera trap data, all of which rely on the random placement of cameras.

The slow emergence of the rational investor: Grain markets and grain storage of rural estates in western Germany, eighteenth and early nineteenth centuries

open access: yesThe Economic History Review, EarlyView.
Abstract We develop new datasets of monthly grain prices in 14 urban markets and of the storage and marketing of grain by 5 rural estates located in western Germany between the late seventeenth century and c. 1860. We explore whether observed patterns of monthly prices, sales, and storage of grain are consistent with the rational competitive storage ...

Technologies for equine welfare and performance monitoring under field conditions – Where do we stand?

open access: yesEquine Veterinary Journal, EarlyView.
Abstract The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex ...

Quantitative assessment of gait alterations and variability in sulky‐driven Standardbred trotters after a standardised exercise test

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Assessment of equine metabolic and locomotory responses to quantified levels of physical exercise is needed to support the creation of tailored protocols for optimal training adaptation. The locomotory response to exercise in horses is not fully understood.

The effect of full‐limb flexion tests on static and dynamic muscle activity and locomotion asymmetry in owner‐sound horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Flexion tests are commonly used in equine locomotion examinations to identify underlying locomotor issues, yet their neuromuscular effects remain poorly understood. Response variability raises concerns about their clinical value in lameness assessments and pre‐purchase evaluations.
