In‐Situ Growth of 2D MOFs as a Molecular Sieving Layer on SnS2 Nanoflakes for Realizing Ultraselective H2S Detection

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The ultraselective H2S detection of the ZIF‐L/SnS2 heterostructure is demonstrated. The introduction of 2‐dimensional (2D) breathable ZIF‐L results in a substantial increase in H2S selectivity attributable to the molecular sieving effect, which impedes the permeation of gases with large kinetic diameters and high polarity.

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Graphene Multi-Protonation: a Cooperative Mechanism for Proton Permeation

open access: yes, 2018
The interaction between protons and graphene is attracting a large interest due to recent experiments showing that these charged species permeate through the 2D material following a low barrier (~ 0.8 eV) activated process.

Intermittent permeation of cylindrical nanopores by water

open access: yes, 2002
Molecular Dynamics simulations of water molecules in nanometre sized cylindrical channels connecting two reservoirs show that the permeation of water is very sensitive to the channel radius and to electric polarization of the embedding material.

Permeation characteristics of tetracyclines in parallel artificial membrane permeation assay

open access: yesADMET and DMPK, 2019
The purpose of the present study was to characterize the passive permeation of tetracyclines in the parallel artificial membrane permeation assay (PAMPA). Tetracyclines exist as zwitterion at physiological pH. The PAMPA membrane was prepared by impregnating a phospholipid/decane solution to a filter support.

Stratum Corneum‐Inspired Zwitterionic Hydrogels with Intrinsic Water Retention and Anti‐Freezing Properties for Intelligent Flexible Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A novel stratum corneum‐inspired zwitterionic hydrogel is developed for intelligent, flexible sensors, featuring intrinsic water retention and anti‐freezing properties. The quasi‐gel, composed of hygroscopic polymers and bound water, maintains its softness across a wide range of humidity.

Layer dynamics of a freely standing smectic-A film [PDF]

open access: yes, 1999
We study the hydrodynamics of a freely-standing smectic-A film in the isothermal, incompressible limit theoretically by analyzing the linearized hydrodynamic equations of motion with proper boundary conditions.

Transdermal delivery of tolterodine tartrate for overactive bladder treatment: In vitro and in vivo evaluation

open access: yesActa Pharmaceutica, 2017
The purpose of the study was to develop a transdermal tolterodine tartrate (TT) patch and to analyse its efficacy for overactive bladder (OAB) treatment. Patches were prepared using various polymers and plasticizers via the solvent casting method.
