Established Short‐Rotation Willow (Salix spp.) as an Effective Facilitator of Native Hardwood Tree Regeneration in New York State, USA

GCB Bioenergy
Afforestation of former agricultural land is increasingly prioritized as a natural climate solution, yet tree establishment is inhibited by herbaceous competition, browsing pressure, limited seed dispersal, and planting costs.

Measurement and Model-Based Control of Solidification in Continuous Casting of Steel Billets

Applied Sciences, 2023
A laser vibrometer system in combination with appropriate artificial intelligence methods for clustering of the measured vibration spectra was tested at a continuous steel casting machine to receive information on the solidification status of the strand.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Semiconducting Covalent Organic Frameworks Based on Spin‐Delocalized Trioxotriangulene Neutral Radicals

Angewandte Chemie, EarlyView.
Imine‐linked 2D covalent organic frameworks incorporating delocalized trioxotriangulene (TOT) neutral radicals were synthesized through complementary routes. Direct incorporation of an amine‐functionalized TOT radical yields a highly crystalline, porous framework (TOT‐COF‐H) with intrinsic semiconducting behavior (σRT = 1.2 × 10−4 S cm−1) and a narrow ...

Beyond Nanoporosity: A CO2‐Conditioned Glassy Matrix Contributes to the Brittle‐to‐Ductile Transition of Nanocellular Polyetherimide

Advanced Materials, EarlyView.
The mechanical performance of nanocellular polyetherimide cannot be explained by nanoporosity alone. It is shown that CO2 saturation and desorption leave a distinct mechanical signature in the glassy matrix before foaming. This matrix contribution provides a new route to understand and optimize the brittle to ductile transition in nanocellular polymers.

The Selective Membrane Filtration of an ESF-generating Factor (EGF) in the Presence of Erythropoietin (ESF)

Experimental Biology and Medicine, 1971
SummaryA mixture of an erythropoiesis stimulating factor (ESF) and an ESF-generating factor (EGF), isolated from the urine of a patient with paroxysmal nocturnal hemoglobinuria (PNH), was separated by selective membrane filtration. The optimum pH for activity of the EGF fraction from the urine of the PNH patient was about 7.4, the same as that ...

Gate‐Induced Critical Current Modulation in W–C Nanowires: The Role of Fabrication

Advanced Materials Technologies, EarlyView.
Focused ion beam induced deposition (FIBID) enables precise control of superconducting W–C nanowire devices. Introducing a Ga+ focused ion beam (FIB) cleaning step reduces substrate damage and suppresses leakage currents, shifting gating thresholds to higher voltages.

Facile, Scalable, and High‐Yield Synthesis of a Near‐Unity Quantum Yield Zero‐Dimensional Copper Halide Cs3Cu2Cl5 Scintillator for X‐Ray Imaging

Advanced Optical Materials, EarlyView.
A dioxolane‐mediated reaction synthesis provides a simple and scalable route to phase‐pure Cs3Cu2Cl5 scintillator powders with near‐complete conversion, near‐unity photoluminescence quantum yield, and long‐term stability. The resulting green‐emitting composite films exhibit strong radioluminescence, high light yield, and practical compatibility with ...
