Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment
Advanced Functional Materials, EarlyView.Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Dipole retardation in a mixture of acetamide and calcium nitrate
Archives of Acoustics, 2014 The results of investigations of the dielectric properties of an acetamide and calcium nitrate mixture (x_acetam = 0.7644) are presented. They are to be complementary to ultrasonic and viscoelastic studies made previously [4].

Contributions to Geophysics and Geodesy, 2019 An important, yet until now neglected, aspect of the viscoelastic behaviour of lavas is the Kramers–Kronig consistency of their complex viscoelastic shear modulus.

Advanced Functional Materials, EarlyView.A modular biosynthetic PVA–gelatin hydrogel crosslinked via visible‐light thiol‐ene chemistry is engineered as a coating for neural electrodes. Optimizing matrix composition and mechanical properties enables the hydrogel to support astrocytic populations that guide neural differentiation and functional maturation.

The activation energy of viscoelastic deformation of rocks [PDF]
Geološki Anali Balkanskoga Poluostrva, 2003 The suggested model, which considers the simultaneous appearance (on the intermolecular scale) of elastic and viscous behaviors of rocks during their viscoelastic deformation, enables the relaxation time, t0, of the viscoelastic deformation energy to be ...

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers
Advanced Functional Materials, EarlyView.Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...

Ultrasonic investigations of 2.ethylhexadiole-1.3. In the region of viscoelastic relaxation
Archives of Acoustics, 2016 This paper gives the results of measurements of mechanical shear impedance in 2-ethylhexadiole-1.3., at frequencies of 0.520, 29.9 and 500 MHz. Measurements carried out with transverse waves in the region of viscoelastic relaxation permitted the ...

Advanced Functional Materials, EarlyView.Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.
