Synthesis of Polysubstituted Naphthalenes via Metal‐Free Borylative Cyclization of o‐Alkynylstyrenes

Advanced Synthesis &Catalysis, EarlyView.
Abstract A selective, metal‐free method for the synthesis of boron‐functionalized polysubstituted naphthalenes via BCl3‐mediated cyclization of α‐substituted o‐alkynylstyrenes is described. The reaction exhibits broad substrate scope, tolerating various groups such as ethers, sulfides and halogens, and delivers high yields under mild conditions, even ...

Printed Recyclable and Flexible Thermocouple Temperature Sensors

Advanced Sensor Research, EarlyView.
Printed recyclable thermocouple sensors with low cost, easy processing, and compatibility with mass production are developed. Using re‐dissolvable polymeric binders, the printed sensors decompose without harsh treatments, while ferromagnetic Ni flakes enable efficient magnetic separation of materials.

Microneedles for Continuous, Minimally Invasive Monitoring: A Technology Overview

Advanced Sensor Research, EarlyView.
This review explores recent advances in electrochemical sensing using microneedles—small, minimally invasive devices that access interstitial fluid for real‐time molecular monitoring. It highlights fabrication methods, materials, and biosensor development, with a focus on aptamer‐based sensing. The review also discusses current applications, challenges,
