Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Transcranial Pulse Stimulation Enhances Dexterity in Parkinson's Disease: A Randomized Sham‐Controlled Trial

Movement Disorders, EarlyView.
Abstract Background Ultrasound‐based neuromodulation, capable of reaching deep brain areas with high precision, represents cutting‐edge technology in non‐invasive brain stimulation and is investigated as a novel treatment for neurological and psychiatric disorders, including Parkinson's disease (PD).

Evaluation of a novel laser‐system operating at 1940 nm for weed control and determining the influence of biological and operational factors

Pest Management Science, EarlyView.
The control efficacy of a novel laser pulse system operating at 1940 nm was tested. The new system allows effective control of young weeds with 1.5 J. Targeting the plant stem is 53‐fold more energy‐efficient than the meristem. Species morphology and beam diameter significantly influence weed control efficacy. Abstract BACKGROUND This study evaluates a

Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

Small, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Near‐Armchair‐Enriched Growth of Single‐Walled Carbon Nanotubes via W‐Containing Fe‐Based Catalyst Systems in Mist FC‐CVD

Small, EarlyView.
A mist‐based floating catalyst chemical vapor deposition (mist FC‐CVD) strategy allows the use of non‐volatile precursors and multi‐component catalyst delivery in a continuous process. Through catalyst composition control, it generates near‐armchair‐enriched single‐walled carbon nanotubes (SWCNTs) and uncovers key factors governing chiral‐angle ...

Tunable Surface Chemistry of Molten Salt Derived MXenes for Data‐Driven Electrochemical Materials Discovery

Small, EarlyView.
The surface chemistries of MXenes have been largely broadened by Lewis acid melts through expanded compositional diversity and functionalization routes. Such complexity makes data‐driven approaches particularly suitable for accelerated functionality discovery. This review examines surface chemistry from synthetic history to structure‐activity relations,

Stress‐Adaptive Biomaterials With Tunable Yielding Architectures Regulate Organoid Morphogenesis

Small, EarlyView.
Granular hydrogels are developed to tune the yield stress levels at which 3D tissue culture matrices undergo plastic deformation. We use these materials to regulate growth‐induced stresses, with demonstrable effects on cancer spheroid invasion and brain organoid morphogenesis.
