Biosynthesis of lignans. Part I . Biosynthesis of Arctiin (3) and Phillyrin (5) [PDF]

open access: yes, 1977
Lignans constitute a class of naturally occuring phenolic compounds, widely distributed in higher plants. They are formally composed of two phenylpropanoid units, stercospecifically joined at the /f-carbon atoms of their side chains. Their biosynthesis

Potato Protein Concentrate: Improving Quality Using a More Effective and Sustainable Method

open access: yesBiology and Life Sciences Forum
One ton of potatoes processed to starch yields 5 to 12 m3 of potato fruit juice (PFJ), containing 30–41 wt% per dry matter protein with a high nutritional value that is comparable to eggs and has all essential amino acids.

A spectroscopic analysis of carbons derived from heat treated phenolic-resins

open access: yes, 1995
The aim of this study is to determine the degree to which the aromaticity of carbons produced from heat-treated (to 1000°C) acid-catalysed phenolic resins is altered when the resin precursors are combined with furfuryl-alcohol, paraformaldehyde and ...

Tannin-based flax fibre reinforced composites for structural applications in vehicles [PDF]

open access: yes, 2012
Innovation is often driven by changes in government policies regulating the industries, especially true in case of the automotive. Except weight savings, the strict EU regulation of 95% recyclable material-made vehicles drives the manufactures and ...

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

open access: yesAdvanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

On the Development of Phenol-Formaldehyde Resins Using a New Type of Lignin Extracted from Pine Wood with a Levulinic-Acid Based Solvent

open access: yesMolecules, 2022
Resole resins have many applications, especially for foam production. However, the use of phenol, a key ingredient in resoles, has serious environmental and economic disadvantages.

Development of phenolic concrete mixes and structural behaviour of phenolic concrete components [PDF]

open access: yes, 1991
This work relates to the development of a method of preparing a filled phenolic resin, for use particularly, but not exclusively, in building materials. The method includes mixing filler and micro-filler, a catalyst, resin and a hetrocyclic alcohol (i.e.

Designing Polymer Nanocomposites for X‐Ray Shielding: Mechanisms, Architectures, and Scalable Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This review highlights advances in lightweight, lead‐free polymer nanocomposites for diagnostic X‐ray shielding. By linking filler chemistry, dispersion, architecture, and photon interaction mechanisms, it establishes structure–performance relationships guiding material design.
