Preparation and Characterization of Urea-formaldehyde Resin/reactive Montmorillonite Composites

, 2017
The urea-formaldehyde resin/reactive montmorillonite composites were prepared by in situ polymerization. The reactive montmorillonite was prepared firstly by being ion exchanged with organic molecules and secondly by being grafted with silane coupling ...

Evaluation of Glycolaldehyde as a Formaldehyde Substitute in Urea-based Wood Adhesives [PDF]

, 2022
Glycolaldehyde, produced from cracking of glucose, was tested as a substitute for formaldehyde in urea-based wood adhesives. Initially, different parameters (water content, aldehyde/urea-ratio, curing temperature, and time) were screened to identify the ...

Sarbecoviruses Suppress Innate Immunity by Recruiting PPM1A to Modulate STAT2 and ORF9b Phosphorylation

Advanced Science, EarlyView.
Sarbecovirus ORF9b recruits host phosphatase PPM1A to suppress innate immunity through dual mechanisms. PPM1A directly dephosphorylates ORF9b to sustain its activity and indirectly downregulates STAT2 phosphorylation to impair interferon signaling. Pharmacological inhibition of PPM1A restores antiviral responses and limits sarbecovirus replication ...

Fire‐Safe Hierarchical Solid Polymer Electrolytes Enabled by Dual‐Functional Microcapsules for Lithium Metal Batteries

Advanced Science, EarlyView.
Dual‐functional fire‐safe microcapsules are integrated into hierarchical solid polymer electrolytes to provide sequential protection against thermal abuse. The ammonium hydrogen phytate‐modified shell forms a protective char barrier, while the thermally triggered release of perfluoro(2‐methyl‐3‐pentanone) actively suppresses combustion, enabling safer ...

The Effect of Ratio of Formaldehyde/Urea (F/U) using Catalyst of NaOH and NH4OH against Production of Urea-Formaldehyde Resin in Laboratory-Scale

, 2016
This study was conducted to investigate the ratio of formaldehyde/urea (F/U) and catalysts against the formation of urea-formaldehyde resin. The F/U was varied in 1.5, 2, 2.5, 3. The catalysts used were NaOH and NH4OH.

HADHA K406 Lactylation Regulates Metabolic Reprogramming and Suppresses Immune Responses in Gastric Cancer

Advanced Science, EarlyView.
HADHA K406 lactylation fuels fatty acid β‐oxidation and HMGCR‐dependent cholesterol biosynthesis, fostering immunosuppressive MDSCs and exhausted CD8+ T cells in gastric cancer. Loss of this modification blocks cholesterol production, remodels the tumor microenvironment, and tumor growth is suppressed via combined inhibition of HMGCR and LDHA ...

Astrocytic Ketogenesis Protects Central Nervous System Injury via CPT1A Stabilization and Epigenetic Regulation

Advanced Science, EarlyView.
A distinct astrocyte subpopulation, enriched at the lesion border, drives CNS repair through enhanced ketone body metabolism. This process promotes neuronal survival and axonal sparing via CPT1A stabilization and H3K9bhb‐dependent epigenetic reprogramming, positioning astrocytic ketogenesis as a promising therapeutic target for tissue regeneration ...

Reduction of formaldehyde emission from urea-formaldehyde resin with a small quantity of graphene oxide

, 2021
application/pdfGraphene oxide (GO) has theoretically been identified as a candidate for adsorbing formaldehyde molecules. However, whether GO can actually serve as a scavenger for formaldehyde resin adhesives must be experimentally verified due to the ...

DUSP26 Regulated by YY1 Lactylation Couples Osteogenesis and Angiogenesis by Dephosphorylating PMPCB at Y141 and Activating Mitophagy in BMSCs

Advanced Science, EarlyView.
p300‐associated YY1 lactylation promotes DUSP26 expression in BMSCs. By regulating PMPCB phosphorylation and PINK1 processing, DUSP26 supports mitophagy, osteogenic differentiation, and pro‐angiogenic factor secretion. BMSC‐derived exosomes carrying a RUNX2 promoter‐driven DUSP26 plasmid favor osteogenic‐lineage transgene expression, partially ...
