Reusable Polyphenol Building Blocks Enable Recyclable Epoxy‐Amine Thermosets via Methanolysis

open access: yesAngewandte Chemie, EarlyView.
A biobased epoxy–amine platform was developed using functional building blocks derived from polyphenols. These thermosets exhibited tunable mechanical and thermal properties, together with efficient, catalyst‐free chemical recycling via methanolysis. Beyond the recovery of reusable building blocks, the recycled polyols could be further upcycled into ...

Additive manufacturing of metal micro-fiber reinforced polymer composites: Processing, mechanical properties, and laminate behavior

open access: yesMaterials & Design
A new class of fiber reinforced thermoplastic composites is investigated. Micro-scale metal alloy fibers produced by modulation-assisted machining (MAM) are added to a PETG (Polyethylene Terephthalate Glycol) polymer matrix by direct extrusion.

FastCat: Autonomous Discovery of Multielement Layered Double Hydroxide Alloy Catalysts for Alkaline Oxygen Evolution Reaction

open access: yesAdvanced Intelligent Discovery, EarlyView.
A machine learning‐guided self‐driving laboratory screened over 500 nickel‐based layered double‐hydroxide catalysts for alkaline oxygen evolution. Out of the eight metals, the robot uncovered a quaternary Ni–Fe–Cr–Co catalysts requiring only 231 mV overpotential to reach 20 mA cm−2.

RR Lyrae Stars in M4

open access: yesEPJ Web of Conferences, 2017
Observations by Kepler/K2 have revolutionized the study of RR Lyrae stars by allowing the detection of new phenomna, such as low amplitude additional modes and period doubling, which had not previously been seen from the ground.

Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology

open access: yesAdvanced Intelligent Discovery, EarlyView.
Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures

Metal–Metal Cooperative C─F and S─F Bond Cleavage by Low‐Valent Tetracobalt Clusters and Water‐Assisted Fluoroarene Hydrodefluorination

open access: yesAngewandte Chemie, EarlyView.
Self‐assembled tetrahedral CoI4 clusters supported by simple bipyridine‐based ligands undergo core rearrangement to cleave S─F and C(sp2)─F bond, forming fluoride‐bridged tetracobalt(II)‐oxo clusters, while exposure of cobalt(I) clusters to molecular oxygen yields cubane‐type cobalt(III) oxo clusters.

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Real‐World Outcomes of Midostaurin Plus Intensive Chemotherapy in FLT3‐Mutated AML: The PETHRATIFY Study

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Mutations in FLT3 are present in approximately 30% of patients with AML. The addition of midostaurin (MIDO) to intensive chemotherapy (IC) became standard of care following the RATIFY trial, but comprehensive real‐world data spanning the full adult age spectrum and including both FLT3‐ITD and FLT3‐TKD mutations remain limited.

Thermally-driven bacterial mechanism of biogenic amines enrichment in central pile-fermentation zones of Liuyang Douchi

open access: yesFood Chemistry: X
Elucidating biogenic amine (BA) enrichment mechanisms in Liuyang Douchi pile-fermentation is crucial for enhancing product safety. This study analyzed spatial-temporal BA profiles and microbial succession. The central zone (M4) exhibited peak temperature
