Molecular‐Level Pore Engineering for Precise Separation via Active Solvent‐Mediated Interfacial Polymerization

Advanced Science, EarlyView.
We demonstrate that microemulsion solvents can actively template molecular‐level pores within selective layer during interfacial polymerization. By creating localized quasi‐homogeneous polymerization zones, the membrane achieved a 7.1‐fold enhancement in water permeance with increased selectivity.

Robot‐Assisted Measurement of the Critical Micelle Concentration

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.

Single‐Step Analog In‐Memory Matrix Computation in Three‐Dimensional Circuits

Advanced Intelligent Systems, EarlyView.
A wooden model illustrates a 3D memristive array designed for single‐step kernel convolutions. It shows how two‐dimensional input data are mapped into the 3D array and convolved in parallel with stored kernels. Color‐coded connection points represent programmed memory‐element values, with each color corresponding to a specific kernel weight.

Revealing the Role of Sidewall Orientation in Wet Chemical Etching of GaN-Based Ultraviolet Light-Emitting Diodes

Nanomaterials, 2019
We demonstrated that the tetramethylammonium hydroxide (TMAH) solution possesses different etching abilities to the chip sidewalls with different orientations because the orientation of chip sidewall determines the exposed crystallographic plane of ...

Carbon‐Doped Amorphous Gallium Oxide Forms a Heterojunction With Water to Improve the Electrocatalytic Oxygen Evolution Reaction

Carbon Energy, EarlyView.
A dynamic catalyst–H2O heterojunction (CWH) forms on ACG during OER, with periodic bubble evolution modulating band bending and interfacial charge transfer. Electron–radical coupling drives the generation of •OH/•O2− species, converting Ga2O3 into GaOOH, whereas surface CO32− from C doping stabilizes the interface, suppressing catalyst dissolution and ...

Assessing the Alkyl Chain Effect of Ammonium Hydroxides Ionic Liquids on the Kinetics of Pure Methane and Carbon Dioxide Hydrates

Energies, 2020
In this study, four ammonium hydroxide ionic liquids (AHILs) with varying alkyl chains were evaluated for their kinetic hydrate inhibition (KHI) impact on pure carbon dioxide (CO2) and methane (CH4) gas hydrate systems. The constant cooling technique was
