Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

open access: yesAdvanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.

Label‐Free Impedimetric Determination of Cortisol Using Gold Nanoparticles Functionalized Laser‐Induced Graphene Interdigitated Electrodes

open access: yesAdvanced Materials Technologies, EarlyView.
Non‐faradaic label‐free impedimetric determination of cortisol is demonstrated with gold nanoparticles (AuNP) functionalized laser‐induced graphene interdigitated electrodes (LIG‐IDE). The AuNP functionalized LIG‐IDE exhibits remarkable characteristics including good logarithmic linear range, high reproducibility, repeatability, and robust selectivity.

Polydiacetylene‐Crosslinked Oligosiloxanes for Dual‐Mode Temperature Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
This work combines polydiacetylenes with oligosiloxanes for enhanced solubility and processability. The hybrid material showcases reversible thermochromism (25–47 °C) and dual‐mode temperature sensing via color shifts and capacitance changes. With improved properties, this work paves the way for scalable optoelectronic flexible and conformable sensors.

Going from Inner‐Skinned to Outer‐Skinned Polyelectrolyte Multilayer Based Hollow Fiber Nanofiltration Membranes

open access: yesAdvanced Materials Technologies, EarlyView.
New negatively charged hollow fiber support membranes with an inverted porous structure are fabricated. These supports are coated with polyelectrolytes to form an outer‐skinned polyelectrolyte multilayer membrane. The membranes show a 3.8x increase in active membrane surface area compared to conventional inner‐skinned polyelectrolyte multilayer ...
