3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...

Importance of interaction between the matrix effect and microbial metabolism in the bioavailability of lignans

Journal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 2180-2189, 15 March 2026.
Abstract BACKGROUND Plant‐lignans are polyphenols with low bioavailability and bioactivity that are transformed by the intestinal microbiota into enterolignans. Our hypotheses are: (i) the way in which plant‐lignans are ingested in the diet affects, in a decisive way, the microbial metabolism of these compounds and (ii) an increase in lignan ...

Sustainable recovery of a chitin–glucan complex–protein biocomposite from yeast biomass using biocompatible ionic liquids

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 691-702, March/April 2026.
Abstract Chitin–glucan complex (CGC) is typically extracted from fungal or yeast biomass using harsh alkaline treatments that not only generate high‐salt, organic‐rich effluents, but also negatively impact the structural and functional properties of the recovered copolymer, while wasting the yeast protein fraction, which is discarded.

Valorization of the peel and husk of guaraná (Paullinia cupana): oil extraction, chemical composition, cytotoxicity, and antitumor potential

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 879-892, March/April 2026.
Abstract Guaraná (Paullinia cupana) is a fruit native to the Amazon region. Due to its widespread use, primarily in beverages, its production has grown over the years. The seed is the only commercially valuable part of the fruit so the guaraná production chain generates byproducts, including peel, husk, and spent seed.

Bottom‐Up Ice Growth Geometry Attenuates Shear Stress and Improves the Cryopreservation of Hematopoietic Stem/Progenitor Cells Under Low DMSO Concentrations

Biotechnology and Bioengineering, Volume 123, Issue 3, Page 582-597, March 2026.
ABSTRACT Studies on cell cryopreservation have been limited by the complexity of the freezing process and challenges on controlling ice formation, managing cooling rates, and optimizing cryoprotectant concentrations. The objective of this study is to evaluate the impact of bottom‐up and conventional radial freezing on the viability of mammalian cells ...
