The Effects of Fiber Furnish on Physical Properties of Paper [PDF]

, 1975
This experiment was designed to determine the effects of fiber furnish on the physical properties of paper. To do this various pulps and combinations of these pulps were formed into handsheets and their physical properties determined. The tests performed

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

An All‐in‐One Lignin‐Based Artificial Thylakoid Nanovesicle Via In‐Situ Confined Growth Strategy for High‐Efficient and Selectivity CO2 Photoreduction

Carbon Energy, EarlyView.
The low light/CO2 capture and slow dynamic transfer of photogenerated electrons hamper photocatalysts’ high activity and selectivity. Inspired by the chloroplast's photosynthesis mechanism, an all‐in‐one lignin‐based artificial thylakoid nanovesicle (AiO‐L‐ATN) is constructed using a confined growth strategy of lignin molecules. The performance of such

Valorization of Juice Industry Waste Into Foam‐Like Materials Using Mycelium as Natural Binder

CleanMat, EarlyView.
This study explores converting carrot pomace, a juice industry byproduct, into eco‐friendly mycelium‐based foams using Aspergillus oryzae. The foams, produced via submerged cultivation, grinding and freeze‐drying, showed promising mechanical properties comparable to commercial foams, offering a sustainable alternative to synthetics while promoting ...
