Exploring the Photophysical Processes of an Al3+ Sensor Based on Schiff Base

open access: yesChemPhysChem, EarlyView.
Multiple excited‐state intramolecular proton transfer (ESIPT) processes and twisted intramolecular charge transfer (TICT) states are observed on the S1 state potential energy surface of an Al3+ sensor. The ESIPT process induces an ultrafast CC rotation process and leads to a non‐emissive TICT state.

Trivalent Rare Earth Adsorption at Phosphonic Acid Monolayers

open access: yesChemPhysChem, EarlyView.
This study explores neodymium (Nd) adsorption on Langmuir monolayers of octadecylphosphonic acid (ODPA) at the air/water interface. Using sum frequency generation spectroscopy and X‐ray fluorescence near total reflection, how Nd ions enhance ODPA deprotonation and drive interfacial water ordering is revealed. The findings challenge classical models and

Evaluating the Aqueous Stability of Alkyl‐/Aryl‐Hydrosilanes by NMR Spectroscopy and GC‐MS

open access: yesChemPlusChem, EarlyView.
The incorporation of hydrosilanes as a carbon bioisostere in bioapplied molecules is under‐explored. In this study, the aqueous stability at neutral pH of representative alkyl‐/aryl‐hydrosilanes is investigated using NMR spectroscopy and GC‐MS.The aggregate data analysis reveals which Si‐H bonds are susceptible to hydrolysis, which will inform future ...

From Tin Mining to Green Tourism—Sungai Lembing's Inspiring Ecological Transformation

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sungai Lembing, once a prominent tin mining town in Malaysia, faced severe environmental degradation and economic decline by the late 20th century due to unsustainable mining practices. This study explores Sungai Lembing's transformation from a mining hub to a model of ecological restoration and sustainable development through a governance‐led
