Investigating the Mechanism of Ion Concentration Polarization Within Nanofluidic Hydrogel Membranes: Experiment and Simulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Molecular dynamics simulations are employed to model ion concentration polarization (ICP) at the nanoscale, revealing fundamental electrokinetic behaviors that align with experimental observations. The study demonstrates how membrane charge, ionic strength, and electric fields affect ion localization and biomolecule trapping, providing mechanistic ...

convection initiation

open access: yesJournal of Applied Research in Geographical Sciences
The structure of deep moist convection can be influenced by various factors, including wind shear, available potential energy of convection, relative humidity, and vertical distribution of these variables. Among these factors, wind shear plays a more significant role in the creation of convection.

Durable Low‐Interfacial Toughness PDMS/SiO2 Coatings with Superior Anti‐Icing and Large‐Scale Deicing Performance in the Natural Field

open access: yesAdvanced Materials Interfaces, EarlyView.
Low‐interfacial toughness PDMS/SiO2 coatings are applied to aluminum substrates and tested under natural high‐altitude conditions. The coatings demonstrate strong anti‐icing, icephobic, and large‐scale deicing performance. Field results highlight delayed freezing, reduced ice adhesion, and stable durability, offering practical insights into the use of ...

Large-scale environmental variables and transition to deep convection in cloud resolving model simulations: A vector representation

open access: yesJournal of Advances in Modeling Earth Systems, 2012
Cloud resolving model simulations and vector analysis are used to develop a quantitative method of assessing regional variations in the relationships between various large-scale environmental variables and the transition to deep convection.

The synchronization of convective lifecycles in an idealized microscopic model [PDF]

open access: yesarXiv
How a cloud ensemble responds to external forcing is a puzzle in tropical convection research. Convectively coupled gravity waves (CCGWs) in a finite domain have controllable wavelengths, providing a convenient simulation setup for studying the cloud ensemble. A multiscale analysis shows that the growth of CCGWs in a finite-domain involves not only the

Modulating Stiffness and Shape of a Soft, Textile‐Based Structure Through Glass Transition of a Conductive Phase‐Changing Polymer

open access: yesAdvanced Materials Technologies, EarlyView.
A variable stiffness structure with shape morphing and shape memory capabilities made from layered textiles and 3D printing material is developed. Direct printing of cPLA on textile electrodes maximizes the electrodes' contact area. This work presents a new method for achieving variable stiffness in small segments of soft, deformable structures, using ...

When tiny convective spread affects a midlatitude jet: spread sequence [PDF]

open access: yesarXiv
We investigate the evolution of spread over three days in a numerical ensemble experiment starting from tiny initial condition uncertainty. We simulate a real event during which three mesoscale convective systems occur in close proximity to the midlatitude jet. The spread evolution is compared with an existing conceptual three-stage model.

Unraveling the Effects of Improved Cooling and Bias Force in the Actuation of a Shape‐Memory Soft Multimaterial Gripper

open access: yesAdvanced Materials Technologies, EarlyView.
This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.
