Precise Real‐Time Measurement of Liquid Viscosity Using Digital Video Data

Advanced Intelligent Systems, EarlyView.
Frame‐by‐frame image similarity analysis is employed to obtain the viscosity of moving liquids in real time. The method allows for online implementation even in harsh environments, replacing complex and invasive experiments. Quantitative knowledge of liquid viscosity is of fundamental importance in many areas of materials synthesis and processing ...

Integration of Cholesterol Oxidase‐Based Biosensors on a Smart Contact Lens for Wireless Cholesterol Monitoring from Tears

Advanced Intelligent Systems, EarlyView.
The combination of a parity‐time symmetry wireless technology with a cholesterol sensor integrated into a smart contact lens enables high‐sensitivity cholesterol sensing at low concentration. Cholesterol plays a critical role in physiological functions, but elevated levels increase the risk of cardiovascular disease.

Copper Single‐Atom Catalyst for Efficient C─S Coupling in Thioether Synthesis

Angewandte Chemie, EarlyView.
We report the first single‐atom catalyst for C─S cross‐coupling, featuring atomically dispersed Cu sites on mesoporous carbon nitride. The catalyst enables efficient, selective, and recyclable thioether synthesis under mild conditions and on a gram scale.

On the second eigenvalue of nonlinear eigenvalue problems

Electronic Journal of Differential Equations, 2018
This article is devoted to the characterization of the second eigenvalue of nonlinear eigenvalue problems. We propose an abstract approach which allows to treat nonsmooth quasilinear problems and also to recover, in a unified way, previous results concerning the p-Laplacian.

Climate‐change‐driven shifts in C3 and C4 grass distributions and leaf traits could lead to changes in community‐level flammability

American Journal of Botany, EarlyView.
Abstract Premise Climate change poses challenges to grasslands, including those of the North American Great Plains Region, where shifts in species distributions and fire dynamics are expected. Our present analysis focuses on remaining grasslands within this largely developed and agricultural region. The differential responses of C4 and C3 grass species
