Pulping characteristics of Dicymbe altsoni from Guyana [PDF]

open access: yes, 1978
A sample consisting of one tree of Dicymbe altsoni from Guyana was examined to determine its pulping characteristics. This sample was not large enough to produce definitive results, but it was considered that an indication could be obtained. Bark content,

Optimal Grazing Exclusion Duration to Enhance Soil Carbon Sequestration in Degraded Grasslands

open access: yesAdvanced Science, EarlyView.
Across China, grazing exclusion reaches the national mean soil organic carbon recovery benchmark sooner in high‐MAP regions (> 500 mm), but recovery is much slower where MAP < 300 mm. Scaling this strategy to 70% of China's degraded grasslands would sequester about 1.52 Pg of soil carbon over 10 years—roughly 17% of annual global fossil‐fuel emissions.

Self‐Healing Starch‐Based Ionogels with Hydroneutral Dipole–Dipole Interactions

open access: yesAdvanced Science, EarlyView.
This work introduces starch‐based, conductive, underwater‐healable, and transparent ionogels for soft electronics (SCUTEs). Starch macromolecules are partially substituted with cyanoethyl groups and incorporated with hydrophobic ionic liquid. The polar yet hydroneutral cyanoethyl groups facilitate strong dynamic dipole–dipole interactions that remain ...

Sustainable Phosphorylated Cellulose Nanocrystals: A Dual‐Affinity Platform for High‐Efficiency Enrichment of Intact Glycopeptides and Phosphopeptides

open access: yesAdvanced Science, EarlyView.
AAA ABSTRACT Protein glycosylation and phosphorylation are critical post‐translational modifications (PTMs) governing nearly all cellular functions, yet their analysis remains challenging due to reliance on costly and unsustainable enrichment materials.
