Deterioration characteristics of cement-improved loess under dry-wet and freeze-thaw cycles.
PLoS ONE, 2021 The effects of cement dosage, compaction coefficient, molding method (vertical vibration method and static pressure method), and dry-wet and freeze-thaw cycles on the mechanical strength of cement-improved loess (CIL) were studied to reveal its strength ...

RESEARCH ON WET-STRENGTH PAPER
Journal of the Japanese Technical Association of the Pulp and Paper Industry, 1951 The authors have researched on a manufacturing method of the wet-strength paper, the copolymerized compounds of melamine and formaldehyde.To make wet-strength paper, resin must be prepared through two stages, before it added into beater.As the first stage, various methylolcompounds are needed to be made of melamine and formaldehyde.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Redispersibility of Paper Under Low Agitation and How It Deteriorates over Time
RecyclingIn many paper applications the paper is supposed to disintegrate into its constituating fibers after disposal. This happens in water with only very little input of mechanical energy.
