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).

Crystallinity, Porosity, and Microstructure of Polyphenylene Sulfide Composite Parts Fabricated by Filament‐Extrusion Additive Manufacturing

Polymer Composites, EarlyView.
High‐performance PPS composites for FFF: formulation and characterization linking microstructure and crystallization to adhesion and mechanical properties. ABSTRACT Polyphenylene sulfide (PPS) was compounded with recycled carbon fibers (rCF) and thermal black (TB) particles, followed by injection molding (IM) and extrusion of the compounded composites ...

Controlling height of hydrangeas with growth retardants

California Agriculture, 1966
Treatment of hydrangea plants with the growth retardant B-Nine is a promising method for saving production costs. The shorter plants do not have to be staked, and blooms are often more beautiful than untreated plants.

Nitroxide‐Mediated Polymerization Synthesis of Geminal Bisphosphonate‐Functionalized (Co)polymers and Their Affinity to Hydroxyapatite Surface

Journal of Polymer Science, EarlyView.
A novel styrenic monomer bearing gem‐bisphosphonate groups is synthesized in a single step. The nitroxide‐mediated (co)polymerization of this monomer proceeds in a well‐controlled manner, yielding bisphosphonate‐functionalized (co)polymers with low dispersity.

Contaminants of emerging concern in agricultural soils: Current understanding, overlooked issues, and future priorities

PLANTS, PEOPLE, PLANET, EarlyView.
Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found
