Blood‐Based Biomarkers in Alzheimer's Disease: Advances in Detection Technologies and Clinical Applications

AGING MEDICINE, EarlyView.
Blood‐based biomarkers are emerging as accessible tools for Alzheimer's disease screening, diagnosis, risk stratification, and longitudinal monitoring. This review summarizes major biomarkers, including Aβ42/Aβ40, phosphorylated tau species, NfL, GFAP, genetic risk markers, and exploratory inflammatory, synaptic, and proteomic candidates.

Beyond Formate Trapping: A Mechanistic Framework for Homogeneous CO2‐to‐Methanol Conversion With First‐Row Transition Metals

Angewandte Chemie, EarlyView.
This review shows that converting CO2 into methanol with catalysts based on abundant first‐row metals requires more than overcoming formate formation. Success depends on balancing hydrogen activation, intermediate reactivity, product release, and catalyst stability.

Particle Swarm Optimization as a Noise‐Tolerant Strategy for High‐Entropy Alloy Research

Advanced Intelligent Discovery, EarlyView.
A customized particle swarm optimization algorithm is benchmarked against batch Bayesian optimization across four high‐entropy alloy oxygen‐reduction landscapes. While both methods locate the global optimum comparably under noise‐free conditions, Bayesian optimization’s surrogate model tends to overfit noisy data.

Enhanced Hydrogen Evolution Activity of MoS2 Through Solid Solution Modification of Its Edge Sites With Ruthenium

Angewandte Chemie, EarlyView.
Modulating the edge sites of molybdenum disulfide significantly boosts hydrogen production. By depositing Ru to form an edge‐coordinated solid solution, we accelerate water dissociation and shift the hydrogen evolution reaction pathway to Volmer–Tafel.

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Operando Identification of the Active Phase in Sr‐Promoted Lanthanum Cobaltite Perovskite‐Derived Catalysts for Ammonia Decomposition

Angewandte Chemie, EarlyView.
Ammonia decomposition catalyzed by base metals: Exsolution of cobalt from perovskites prepared by spray‐flame synthesis (SFS) yields highly active, SrO‐promoted Co/La2O3 catalysts with low cobalt content. Operando studies provide insight into the function of the promoter. Dynamic surface reconstruction under operating conditions increases the interface

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

Angewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

Active‐Site Photothermal Energy Utilization in PET Depolymerization

Angewandte Chemie, EarlyView.
Photothermal catalysis enables efficient PET depolymerization, yet the role of active‐site temperature remains unclear. A catalytic activity reversal between Pd–CNG and PdPOM–CNG is observed under thermal and photothermal conditions. Efficient nanoscale photothermal energy delivery raises active‐site temperature, compensates for lower intrinsic ...

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Angewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote
