Biopolymer-based hydrogel formulations for improved seed coating performance
Biopolymer-based hydrogel formulations for improved seed coating performance Lisa Lock Scientific Editor Robert Egan Associate Editor As climate change, soil degradation, and water scarcity place growing pressure on agriculture, scientists are looking for new ways to help crops germinate and grow more efficiently while reducing environmental impact. A new study involving researchers from Nazarbayev University's National Laboratory Astana published in Scientific Reports proposes a promising...
Nonlinear rheology of laminin-111-modified hyaluronan hydrogels
We experimentally assess the nonlinear rheology of composite biopolymer hydrogels composed of thiolated hyaluronic acid, poly(ethylene glycol) diacrylate (PEGDA), and laminin-111 in varied concentrations. We focus in particular on the influence of laminin on the mechanics of the assembled hydrogels, reporting nonlinear rheological measurements for gels under applied shear and compressive load. We find that increasing the concentration of laminin in the synthesized gels reduces the linear...
Bistability of cellular traction on strain-stiffening substrates
Announce Type: new Abstract: To migrate, cells exert traction forces on the extracellular matrix (ECM) -- a biopolymer network that often exhibits nonlinear strain-stiffening elasticity. Cellular tractions can therefore stiffen the ECM. At the same time, cells exert stronger tractions on stiffer ECM.
A pectin and chitosan film to protect bioactive compounds in foods and therapies
A pectin and chitosan film to protect bioactive compounds in foods and therapies Lisa Lock Scientific Editor Andrew Zinin Lead Editor Researchers at IMDEA Materials Institute and the Institute of Polymer Science and Technology (ICTP-CSIC) have developed an innovative biodegradable multilayer film capable of protecting and controlling the release of anthocyanins inside the body. Published in the International Journal of Biological Macromolecules, this innovation opens the door to more...
Multi-Scale Feature Attention Network for Polymer Classification using THz Dual-Comb Spectroscopy
Announce Type: new Abstract: Reliable polymer identification is essential for ensuring the quality and safety of recycled plastics, yet conventional sorting and spectroscopic techniques often struggle to deliver robust discrimination. Terahertz Dual-Comb Spectroscopy (THz-DCS) offers a promising alternative, providing rapid, high-resolution, and non-destructive measurements. In this work, we leverage THz-DCS to classify 12 types of polymers, including pure polymers, multilayer films,...
