Giant Berry‐phase‐Driven X‐Ray Beam Translations in Strain‐Engineered Semiconductor Crystals

open access: yesAdvanced Materials, EarlyView.
Due to the Berry‐phase effect, X‐rays propagating in deformed crystals undergo large translations, interesting for X‐ray optics applications. Here, the lattice expansion observed upon H irradiation of dilute‐nitride semiconductors is exploited to engineer the deformation landscape of selectively hydrogenated GaAsN epilayers.

Modular Assembly of Dynamic Polymer Networks From Heteroaffinity Cross‐Links to Multivalent Proteins

open access: yesAngewandte Chemie, EarlyView.
This study develops a method to modularly assemble oligomeric binding proteins, like streptavidin, using heterobifunctional cross‐linkers that have both a strong‐ and a weak‐affinity binding moiety. These dynamic cross‐linkers enable the assembly of polymer networks with unique meta‐stable nonequilibrium topologies, and that exhibit chemically tunable ...

High‐Throughput In Vivo Screening Using Barcoded mRNA Identifies Lipid Nanoparticles With Extrahepatic Tropism for In Situ Immunoengineering

open access: yesAdvanced Materials, EarlyView.
A high‐throughput in vivo mRNA LNP screening platform is developed and employed to screen a large library of 122 mRNA LNPs in vivo for delivery to immune, stromal, and parenchymal cells, identifying promising LNP candidates. A novel small particle flow cytometry‐based protein adsorption analysis method is utilized to interrogate protein corona ...

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

open access: yesAdvanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Increased Blood Flow and Tendon Swelling Precedes Vascular Expansion and Tissue Matrix Changes In Early Human Tendinopathy: A Potential Window for Superior Treatment Response

open access: yesAdvanced Science, EarlyView.
Human participants with early‐ or chronic‐stage tendinopathy and healthy controls are investigated using ultrasound Doppler, 3T and 7T MRI, and tendon biopsies. Tendon swelling and hyperperfusion are evident early, while vascular growth and extracellular matrix changes are most pronounced in chronic tendinopathy. Early intervention may provide superior

Influence of Hydrogen‐Incorporation on the Bulk Electronic Structure and Chemical Bonding in Palladium

open access: yesAdvanced Science, EarlyView.
Hydrogen incorporation in palladium is directly probed using in situ ambient‐pressure hard X‐ray photoelectron spectroscopy under realistic, application‐relevant conditions. Correlated structural, spectroscopic, and theoretical analysis reveals how hydrogen loading modifies structure, electronic structure, and metal‐hydrogen bonding, resolving long ...

Climate Change Agricultural Comparative Advantage and the US Trade Balance

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.

The amazing architecture of the Dacians. Few thoughts concerning the use of mortars based on new analyses [PDF]

open access: yesPlural: History, Culture, Society, 2019
In 2016, while carrying out a campaign on a Dacian “tower-house” type structure identified in earlier years on the Cetățuie Hill in Ardeu, an atypical material was noticed on the inferior surface of a stone block sitting perpendic¬ular on the revetment ...

3D investigation and modeling of the geometric effects on porosity in packed beds

open access: yesAIChE Journal, EarlyView.
Abstract In porous beds, physical boundaries restrict particle arrangement, leading to inhomogeneous porosity. This paper reports on the porosity profiles that are the result of geometric effects on monodisperse packed beds in cylindrical and cubic arrangements. Special focus is given to the influence of edges and corners in cubic geometries.

Advanced Experiment Design Strategies for Drug Development

open access: yesAdvanced Intelligent Discovery, EarlyView.
Wang et al. analyze 592 drug development studies published between 2020 and 2024 that applied design of experiments methodologies. The review surveys both classical and emerging approaches—including Bayesian optimization and active learning—and identifies a critical gap between advanced experimental strategies and their practical adoption in ...
