Dual‐Site Catalysis in Electrocatalytic C–N Coupling: Challenges and Design Principles

open access: yesChemElectroChem, Volume 13, Issue 11, 3 June 2026.
This review examines dual‐site catalysis in electrocatalytic C─N coupling through four recurring challenges: energetic barriers, kinetic mismatch, selectivity loss, and systemic constraints. It highlights how rationally designed dual‐site catalysts cooperatively lower reaction barriers, synchronize intermediate generation, suppress competing pathways ...

The adsorption of methylamine on Pt single crystal surfaces

open access: yes, 1999
The irreversible adsorption of methylamine at platinum single-crystal electrodes has been studied by a combination of electrochemical and in situ spectroscopic techniques. From purely electrochemical data, it has been stated that the adsorption of CH3NH2

Erasable FAP Targeted Spray‐On Probe for Fluorescence‐Guided Surgery

open access: yesAdvanced Science, Volume 13, Issue 32, 9 June 2026.
We present the first erasable spray‐on probe for fluorescence‐guided surgery. Following topical delivery, FAP‐FLASH550 targets fibroblast activation protein–expressing stromal cells, delineating tumor margins with high tumor‐to‐background ratios. A 365 nm UV light pulse rapidly erases fluorescent signals through triazene photodegradation and subsequent

An In‐Line Machine Vision–Based Profilometry Tool for Non‐Destructive Thickness Assessment of Perovskite Films

open access: yesAdvanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
This work proposes a machine‐vision‐based tool for predicting the thickness of in‐line deposited perovskite films, enabling real‐time decision making to control deposition parameters. The workflow integrates perovskite deposition and annealing with uniformity analysis and minimodule fabrication.

Deciphering pH Behavior in Deep Eutectic Solvents: Synergizing Experimental Data and Computational Modeling

open access: yesChemCatChem, Volume 18, Issue 11, 15 June 2026.
Proton activity in deep eutectic solvents (DESs) remains difficult to quantify. Here, pH in hydrophilic and hydrophobic DESs is probed by combining glass electrode measurements with ultraviolet–visible (UV–vis) pH indicators and Gaussian process (GP) machine learning (ML).

Methanimine as a sink in the HCN and HNC solid state hydrogenation network

open access: yesAstronomy & Astrophysics
Aims. We aim to provide a systematic and quantitative description of the hydrogenation network connecting HCN and HNC to methylamine on interstellar water ices, and to identify the dominant reaction pathways and potential bottlenecks. Methods.

Interactions between 2D Halide Perovskite Materials and Methylamine

open access: yes, 2020
Halide perovskites offer exciting potential as photovoltaic materials and simply as semiconductors. Specifically, their structural tunability has become of greater interest as researchers begin to search for novel ways to tune the materials to achieve ...

Redox‐Neutral and Diastereoselective Cross‐Pinacol Coupling of Pyridyl Ketones With Amine‐Derived Aldehydes

open access: yesChemistryEurope, Volume 4, Issue 6, June 2026.
A redox‐neutral strategy enables cross‐selective pinacol coupling between pyridyl ketones and amine‐derived aldehydes using a samarium catalyst and visible‐light antenna ligand, affording the desired cross‐coupling products in high yields with excellent diastereoselectivity.

Effect of Urea and Methylamine on Plasmin.

open access: yesExperimental Biology and Medicine, 1957
Conclusions1. Preparation of partially purified and highly active human plasmin free of streptokinase is described. 2. In neutral solutions plasmin undergoes rapid auto-digestion at 37°C. 3. Autolysis of plasmin can be inhibited by concentrations of urea and methylamine which inhibit digestion of protein by plasmin.
