Preparation and properties of flame retardant microfiber synthetic leather base

open access: yes
To solve the problem of poor stability of additive flame retardant waterborne polyurethane, a series of waterborne polyurethane with flame retardant properties was synthesized by prepolymer method using aliphatic polyisocyanate, polyether polyol, and ...

Mechanochemical Transformation From Zigzag‐Type Layered/Phenakite to Disordered Rocksalt in Mn‐Rich Cathodes for Li‐Ion Batteries

open access: yesSmall, EarlyView.
Mechanochemical activation drives the transformation of a Mo/F‐modified layered/phenakite precursor into a Mn‐rich disordered rocksalt phase. The resulting disordered rocksalt structure improves cation mobility and structural reversibility during cycling, enabling higher reversible capacity and enhanced electrochemical performance.

Rounded Monodisperse Fluorescent Nanodiamonds

open access: yesSmall, EarlyView.
Nanodiamond (ND) shape control using rapid molten‐nitrate etching is studied as a scale‐up method for monodispersed rounded particles. Optimal etching condition (567°C for 6 min) yields NDs with atomically stepped surfaces and reduced sp2 content. Compared to angular control, rounded NDs exhibit an increased proportion of luminescent particles (66% vs.

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

open access: yesStructural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

open access: yesJournal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Prevalence and risk perceptions of nicotine pouch use: A systematic review of population‐based studies

open access: yesAddiction, EarlyView.
Abstract Background and Aims Oral nicotine pouches (NPs) are a new class of non‐combustible nicotine products that have gained rapid popularity. Despite rising sales and marketing, evidence of their prevalence and risk perceptions remains limited. This systematic review aimed to synthesize the available global evidence on the prevalence and patterns of
