From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Spatial Distribution of Parthenium hysterophorus: Impact on Plant Species Diversity and Soil Characteristics in Gamo Zone, Southern Ethiopia

open access: yesPlant-Environment Interactions, Volume 7, Issue 2, April 2026.
ABSTRACT The invasions are severe and have an impact on pasture lands, farmlands, and conservation areas. However, there is little data on Parthenium hysterophorus L. (Parthenium) mapping using GIS in the Southern Region of Ethiopia. The objective of this study was to map the spatial distribution of Parthenium which affects the diversity of plant ...

Locally‐led maladaptation as a configuration of responsibilities: ethnographic photo essay of a bamboo wall in Bangladesh

open access: yesDisasters, Volume 50, Issue 2, April 2026.
Abstract The construction of bandals (bamboo walls) is a widely practised climate adaptation initiative in Bangladesh, embodying community agency. This article interrogates how it can also represent locally‐led maladaptation—adaptive efforts that inadvertently sustain or exacerbate the very risks they seek to address.

Making Molecular Diagnostics Faster

open access: yesInternational Journal of Laboratory Hematology, Volume 48, Issue 2, Page 272-280, April 2026.
ABSTRACT Background Over the past 40 years, molecular diagnostic methods have evolved from multi‐step, time‐consuming protocols towards either rapid targeted tests or expansive, massively parallel testing. Aims Here we consider the speed limits of targeted molecular diagnostics, considering the three sequential required steps: nucleic acid preparation,

Sudden Shift From Drought to Flood May Be Infrequent in Debris‐Flow Events in Southwest China: Evidence From Antecedent Hydrometeorological Fingerprints

open access: yesAtmospheric Science Letters, Volume 27, Issue 3, March 2026.
Using reanalysis meteorological data and remotely‐sensed soil moisture, we examined antecedent hydrometeorological fingerprints of debris flows in Southwest China (2008–2018). Results show that about 80% of events occurred after anomalously high temperatures, while soils were predominantly wet (96.6%).

The Effects of Nitrate on Brown Fat Fraction and Activation in Older Adults With Type 2 Diabetes: A Randomised, Double‐Blind and Placebo‐Controlled Crossover Trial

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 3, March 2026.
ABSTRACT Type 2 diabetes mellitus (T2DM) is a metabolic disease characterised by chronic hyperglycaemia, whereas obesity is a major risk factor which increases morbidity and mortality. Treatments that alter white adipose tissue to express a metabolically active brown adipose phenotype in rats may offer adjunct treatment in people with T2DM.
