Non‐Canonical Amino Acids for Engineering Peptides and Proteins with new Functions

Israel Journal of Chemistry, Volume 64, Issue 8-9, September 2024.
Abstract The universal genetic code, which specifies the 20 standard amino acids (AAs), forms the basis for all natural proteins. Researchers have developed efficient and robust in vivo and in vitro strategies to overcome the constraints of the genetic code to expand the repertoire of AA building blocks that can be ribosomally incorporated into ...

Conversion of WastePaper into Dissolving Pulp: A Path for Circular Bioeconomy

ChemistrySelect, Volume 9, Issue 30, August 12, 2024.
The potential of wastepaper to produce dissolving pulp was demonstrated in this article. By employing and optimizing chemical processes to wastepaper pulp, a noteworthy increase of 84 % in pulp Fock reactivity was achieved (from 45.6 % to 84.1 %). The pulp characteristics were followed throughout the different treatments allowing better understanding ...

Lignin studies I. Investigations concerning lignin determination

Agricultural and Food Science, 1957
In this investigation a sulphuric acid method for the determination of lignin is presented and the influence of various details critically studied. The samples ground to pass through a 60 mesh (0.25 mm.) screen gave 0—5 % smaller results than those ...

Gut Epithelial Barrier Function is Impacted by Hyperglycemia and Secondary Bile Acids in Vitro: Possible Rescuing Effects of Specific Pectins

Molecular Nutrition &Food Research, Volume 68, Issue 11, June 2024.
Specific BAs are involved in maintenance of gut barrier function. BA metabolism may be disturbed in IBD and diabetes. This might be solved by supplementing the diet with specific dietary fibers such as DM19HB and DM43HB pectins. Gut epithelial barrier disruption is commonly observed in Western diseases like diabetes and inflammatory bowel disease (IBD).

Improved Cellulose Yield in the Production of Dissolving Pulp from Bamboo Using Acetic Acid in Prehydrolysis

BioResources, 2014
Despite increasing demand for dissolving pulps from raw material, production costs remain quite high compared to regular paper pulp. Research literature to date has focused on improving performance and quality but has not simultaneously explored how to ...

Incorporating Nanoparticles in Porous Foam Templating for Enhanced Sensitivity of Capacitive Pressure Sensors

Advanced Sensor Research, Volume 3, Issue 5, May 2024.
This work introduces the incorporation of silica nanoparticles (SNPs) in the templating process of porous foams for capacitive pressure sensors. The SNPs change the microstructures and porosity of the foams, which results in significant enhancement of sensitivity for pressures below 2 kPa, leading to linearization of sensitivity of the pressure sensor ...

Current Approaches on Natural Fiber Reinforcement Surface Treatment for Construction Material Application

International Journal of Polymer Science, Volume 2024, Issue 1, 2024.
The conversion of waste into value‐added products is critical to long‐term sustainability as waste disposal costs, landfilling space, and climate change would be reduced. Research and production industries investigate the possible use of natural fibers as a substitute for fossil fuels.

Production of a cellulosic substrate susceptible to enzymatic hydrolysis from prehydrolyzed barley husks

Agricultural and Food Science, 2008
An effective process for the chemical-biotechnological utilization of barley husks is reported. A first treatment with sulfuric acid (prehydrolysis) allowed the solubilization of hemicelluloses to give xylose-containing liquors (suitable to make ...
