Supramolecular aggregation governs the interfacial adsorption, diffusion, and fixation of anthraquinone‐based vat dyes in meta‐aramid fibers. By correlating reduction chemistry, aggregate formation, and fiber microstructure, a multiscale mechanism for aggregation‐controlled dyeing is established, providing an effective strategy to suppress surface dye ...

Modification of geopolymer surface with a silane coupling agent containing quaternary ammonium group enables the development of dual‐functioning ion exchanger for both cations and anions. In the present study, the performance of this material was demonstrated for the uptake of ammonium and nitrate from water.

A controlled layer‐by‐layer growth process integrates conjugated metal‐organic framework thin films onto a hierarchical 3D laser‐induced graphene scaffold. When incorporated into an extended‐gate field‐effect transistor configuration, this synergistic hybrid platform achieves robust aptamer immobilization, driving highly selective, picomolar‐level ...

The importance of dissolved organic nutrients in the biogeochemistry of oligotrophic gyres [PDF]
The aim of this thesis is to contribute to the observational database in order to address fundamental questions as to how dissolved organic nutrients influence N and P budgets, how they affect nutrient cycling and the sustainment of biological production

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications
A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.

Analysis of the carbon and nitrogen limitations to soybean yield [PDF]
Soybeans are hypothesized to be “self-destructive” since they apparently need to translocate large amounts of nitrogen from vegetative tissues during seed-fill to sustain seed growth.

Flexible silicon carbide (SiC) microelectrode arrays enable high‐fidelity, multichannel cell extracellular recording and precise localized ablation. SiC has been extensively evaluated to persist long‐term in chronic physiological conditions while remaining robust, with excellent electrical and electrochemical stability.

Interaction of Azospirillum lipoferum with wheat germ agglutinin stimulates nitrogen fixation [PDF]
In vitro, the nitrogen fixation capability of A. lipoferum is efficiently increased in the presence of wheat germ agglutinin (WGA). A putative WGA-binding receptor, a 32-kDa protein, was detected in the cell capsule.
