Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality

Journal of Polymer Science, Volume 64, Issue 16, Page 3364-3381, 15 August 2026.
Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...

Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, Volume 29, Issue 25, 4 July 2026.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

Characterization of Structure and Morphology of Cellulose Lyocell Microfibers Extracted from PAN Matrix

Polysaccharides
Polymer matrices can be reinforced with cellulose fillers in a variety of geometric shapes. Depending on the morphology of the particles, the volume fraction of the composite additive may decrease, while the values of the elastic modulus may increase ...

Racemisation of Amino Acids: From Synthetic Challenge to Biological Significance

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Racemisation, once considered an undesirable synthetic side reaction, also occurs naturally in amino acids and influences biological processes. Evidence links stereochemical conversion to ageing, protein turnover, and cellular development. This review examines mechanisms, control strategies in synthesis, applications and implications in physiology ...

From Viscose to Lyocell‐Type Fibers: Chemical Recycling of Viscose and Modal Fibers Using the Ioncell Process

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
Using the Ioncell process, the recycling of low DP textile waste via four case studies, white, blue, and black viscose and white modal fibers, was investigated. The most common man‐made cellulose fiber (MMCF) is viscose, a low DP material made of plant‐based cellulose, and it accounts for less than 6% of the total amount of textile fibers.

Synthesis, Biological Evaluation, and Molecular Docking Studies of 2r,3t,4c‐Configured C‐Furanosidic LpxC Inhibitors

Archiv der Pharmazie, Volume 359, Issue 6, June 2026.
To provide a full picture of the effects of stereochemistry on the biological activity of C‐furanosidic LpxC inhibitors, in chiral pool syntheses starting from d‐mannitol and d‐galactose, a series of four 2r,3t,4c‐configured C‐furanosides was synthesized and tested for LpxC inhibitory and antibacterial activity as well as in vitro ADMET properties ...

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...
