Porous Hybrid Soft Actuators From Liquid Crystal Networks and Lyotropic Chromonic Liquid Crystal Templated Hydrogels

open access: yesAdvanced Materials, EarlyView.
The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...

Modelling of a thin film thermoelectric micro-Peltier module [PDF]

open access: yes, 2004
A micro Peltier cooler/heater module has been modelled. The module consists of n-type bismuth telluride and p-type antimony telluride thermoelectric materials. The commercial software package CFD-ACE+ has been used to implement and analyse the model.

Decoupling Dynamics and Crosslink Stability in Supramolecular Hydrogels Using Associative Exchange

open access: yesAdvanced Materials, EarlyView.
How does reorganization impact the stability of supramolecular hydrogels? In contrast to dissociative crosslink exchange, implementing associative exchange in macroscale DNA hydrogels enables decoupling of reorganization dynamics from thermal and mechanical stability.

Oxygen‐Inhibition Driven Compartmentalization of Dextran Microgels: Toward Fusible Colloidal Biomaterial Inks for 3D Printing

open access: yesAdvanced Materials, EarlyView.
Harnessing oxygen inhibition as a materials design principle enables the universal fabrication of core–shell microgels with tunable radial crosslinking gradients. This conceptually simple yet highly versatile strategy generates fusible colloidal bioinks that combine structural hierarchy with adaptive porosity.

Performance analysis of nanostructured Peltier coolers

open access: yes, 2018
Employing non-equilibrium quantum transport models, we investigate the details and operating conditions of nano-structured Peltier coolers embedded with an energy filtering barrier.

FRICTIONAL ELECTRICITY AND TOOL MATERIALS WEAR

open access: yesAdvanced Engineering Research, 2011
Thomson spatial heat sources power is determined. It is shown that the heating spatial source helps reduce the total flow quantity entering the plate, and expand heat penetration.

Local Peltier-effect-induced reversible metal–insulator transition in VO2 nanowires

open access: yesAIP Advances, 2016
We report anomalous resistance leaps and drops in VO2 nanowires with operating current density and direction, showing reversible and nonvolatile switching. This event is associated with the metal–insulator phase transition (MIT) of local nanodomains with

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

open access: yesAdvanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.
