this research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. heat conduction equation in cylindrical coordinate system is solved. thermal conductivity coefficient is graded along the radial direction. by considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...

The development of multistimuli-receptive actuators demands a rational combination suitable functionalities. Achieving such actuating properties in single crystalline material is challenge. In spite several investigations on photo-, thermo,- and mechano-responsive crystals, displaying all these effects rare. By judicious photoreactive 2-fluoro-4′-styrylpyridine units flexible Pb3(SCN)3 units, m...

The hybrid integration of polymer and silica in optical waveguides can yield devices that combine the excellent thermo-optic properties of polymers and the superior passive waveguiding properties of silica. The large difference and opposite sign of the thermo-optic coefficients of both classes of materials can be utilized to create athermal waveguide devices. In addition, it can be utilized in ...

Electro-magneto-thermo-elastic response of a thick double-layered cylinder made from a homogeneous interlayer and a functionally graded piezoelectric material (FGPM) outer layer is investigated. Material properties of the FGPM layer vary along radius based on the power law distribution. The vessel is subjected to an internal pressure, an induced electric potential, a uniform magnetic field and ...

A thermo-responsive PNIPAAm-grafted-PDMS (PNIPAAm-g-PDMS) surface was used for cell culture. Cos7 cells could adhere to the PNIPAAm-g-PDMS surface and proliferated therein at 37 C. The cultured cells could detach from the surface at room temperature without trypsin digestion. The viability of cells harvested from the PNIPAAm-g-PDMS surface via lowering temperature was higher than that of cells ...

Headspace solid-phase microextraction was used to extract low-molecular mass degradation products formed during thermo-oxidation of virgin and inplant recycled polyamide 6.6 at 100°C for up to 1200 hours. A total of 20 degradation products were identified using GC-MS. The identified degradation products shared some common structural features and were categorised into four different groups: cycl...
