Fundamentals of water as a solvent could lead to greener cellulose-based products
To do so, he worked with colleague Jim Martin, professor of chemistry at NC State, who studies the fundamental properties of water as a solvent. "Water has the uncanny ability to change characteristics depending on what it's with, which gives…

What is the difference between puncture strength and tear strength? | How to read 'strength' in a datasheet
Datasheets list several items labeled 'strength,' such as 'tensile strength,' 'tear strength,' and 'puncture strength.' While all of these seem to represent the strength of a film, they are not measuring the same thing. This article organizes what kind of…

If it says "biodegradable," does it disappear anywhere?
Much of it is said not to decompose in the natural environment even after a very long time.There are also reports that there is a large amount of plastic waste on the deep-sea floor, and that half of it…

Corn Stover Transformed Into Biodegradable Composites and Bacterial Nanocellulose
Researchers built three additive-free corn stover biocomposites with tunable degradation and upcycled their hydrolysates into bacterial nanocellulose. Subject of Research: Development and end-of-life evaluation of corn stover biocomposites made with starch, alginate, and PHBH matrices, including a coat-hanger prototype and…

3D-printed boron nitride composites tune heat flow through platelet alignment
Masked stereolithography 3D printing aligns boron nitride platelets through filler size and layer thickness, raising in-plane thermal conductivity by up to 246 percent over neat resin. Subject of Research: MSLA 3D printing of hexagonal boron nitride platelet-filled polymer composites with tunable thermal and…

Bacterial cellulose nanocrystals may offset MPC’s damage to dental cement strength
An in-vitro study found that adding bacterial cellulose nanocrystals to resin-modified glass ionomer cement preserved its mechanical properties, while 2-methacryloyloxyethyl phosphorylcholine reduced flexural and tensile strength and increased surface roughness. News Source: Drew Townsend. (October 27, 2026). Bacterial cellulose nanocrystals may offset…

Thicker walls and more openings raise bending loads in PLA specimens
Experimental and finite-element results show that thicker walls and more openings increased peak bending-load capacity in the FDM-produced PLA specimens tested. Increasing wall thickness or the number of openings markedly improved the peak bending-load capacity of polylactic acid (PLA) specimens…

Cocoa Husk Pectin Films Show UV Shielding, Antioxidant Activity, and Rapid Soil Disintegration
Pectin extracted from cocoa husk waste has been cast into biodegradable films that shield ultraviolet light, scavenge free radicals, disintegrate rapidly in soil, and can be regenerated by dissolution and recasting, according to a new study. Petroleum-derived packaging materials are…
