Nanostructured Bismuth Film Electrode for Detection of Progesterone

Sensors, 2018
Progesterone is an important hormone responsible, among others, for maintaining pregnancy via inhibition of uterus muscles activity; thus, following its concentration levels in pregnant women is of immense importance in the endeavor to prevent premature ...

Ligand‐Dependent Locally Excited and Charge‐Transfer Emission in Linear Copper(I) Mesoionic Carbene Luminophores

Advanced Optical Materials, EarlyView.
Ligand engineering enables precise control of emission in linear Cu(I) complexes by tuning donor–acceptor interactions between electron‐rich amines and π‐accepting mesoionic carbenes. Naphthyl‐substituted carbenes promote locally excited phosphorescence with vibronic structure, whereas electron‐rich amides combined with electron‐poor carbenes favor ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Electrochemical reduction and cathodic stripping voltammetric determination of clotrimazole

Journal of the Brazilian Chemical Society, 2001
The reduction of clotrimazole at a mercury electrode, in phosphate buffer, pH>6, involves a reversible one-electron process. The electrochemical process presents a large contribution from adsorption effects.

Toward Prostate Cancer Early Warning with a Self‐Powered Wearable Biosensing Platform Integrated with Machine Learning

Advanced Science, EarlyView.
ABSTRACT Current prostate cancer detection methods remain limited in non‐invasiveness and specificity, prompting interest in urinary biomarkers such as sarcosine. Here, we report a urine‐powered wearable platform for non‐invasive sarcosine detection as a proof‐of‐concept for decentralized early warning.
