Resumen de: US20260308782A1
A redox-active, conductive, polycationic, and coordinating polymer with a coordinative redox deposition for oxygen evolution reaction (OER) electrodes. The electrodes can contain low loadings of earth-abundant catalysts and are highly active and stable under harsh conditions. The preparatory methods described herein are straightforward and can be utilized to prepare electrodes with different supports and metal ion precursors. Polycarbazole (PCz) provides a highly conductive, stable support for the OER catalysts. XPS and UV-vis studies indicate that the deposition proceeds by coordination to the nitrogen sites in PCz. PCz is believed to provide a local high OH— for the turnover limiting step in the OER.

Resumen de: WO2026208797A1
The present application relates to the technical field of shielding adhesives. Disclosed is a shielding coating material. By means of a synergistic effect between a component A and a component B, when applied to a shielding adhesive, the two components can reduce the cost of the shielding adhesive, further improve the weather resistance of the shielding adhesive, reduce the film-forming thickness of the shielding adhesive and endow the shielding adhesive with a good shielding effect. Specifically, in the present application, SBS undergoes grafting modification to have a carboxylic acid functional group and an epoxy structure, thereby obtaining the component A. In the present application, the surface of silver powder is treated with an organic acid to obtain modified silver powder, the modified silver powder having a higher conductivity than ordinary silver powder. The carboxylic acid functional group in the component A helps the component B to be better dispersed in the component A, thereby reducing the occurrence of deterioration in the shielding effect caused by voids generated by the stacking of flaky silver powder. Moreover, the epoxy structure helps the component A to undergo ring-opening crosslinking in the shielding adhesive, thereby improving the reliability of the shielding adhesive. In addition, also provided in the present application is a preparation method for the shielding coating material.

Resumen de: US20260294293A1
0000 A system and method provide non-invasive, continuous monitoring using a plurality (swarm) of programmable, battery-less, autonomous, biodegradable smart dust particles (SDPs). Each SDP features sensors printed on a layered separating medium for chromatographic separation and an RFID tag comprising a unique identification (ID) barcode. Applied to skin overlying biological tissue, optionally via spray, the SDPs transmit signals wirelessly to an external receiver. A processor correlates received signals with spatial coordinates on the skin using each SDP's unique ID. This enables the generation of a spatiotemporal chemical tomogram, mapping detected chemical compounds (e.g., VOCs) across the underlying biological tissue. The system facilitates applications such as wearable tomography and continuous tumour diagnostics, including monitoring for conditions like breast cancer by analysing the chemical map over time.
