High‐Entropy Ti, Zr, Hf, Ta Multiphase Diboride with Deformation Resistance up to 2000 °C

open access: yesAdvanced Engineering Materials, EarlyView.
Ceramics are brittle and strength decreases with temperature. The multiphase high‐entropy (Ti0.25Ta0.25Hf0.25Zr0.25)B2 with heterogeneity at the nano‐ and microscale demonstrates deformation resistance up to 2000 °C, with maximum bending strength at 1800 °C.

Design and Evaluation of 3D‐Printed Polylactic Acid Composites Reinforced with Biodegradable Bamboo Powder and Jute Powder

open access: yesAdvanced Engineering Materials, EarlyView.
The study investigates 3D‐printed polylactic acid (PLA) composites with biodegradable bamboo and jute powder fillers. Mechanical, thermal, structural properties, and rheological behavior are discussed to evaluate composite performance. Morphological characterization indicates uniform dispersion and adhesion of the fillers in the PLA matrix with the ...

In situ GaN decomposition analysis by quadrupole mass spectrometry and reflection high-energy electron diffraction [PDF]

open access: yesJ. Appl. Phys. 104, 033541 (2008)
Thermal decomposition of wurtzite (0001)-oriented GaN was analyzed: in vacuum, under active N exposure, and during growth by rf-plasma assisted molecular beam epitaxy. The GaN decomposition rate was determined by measurements of the Ga desorption using in situ quadrupole mass spectrometry, which showed Arrhenius behavior with an apparent activation ...

Fabrication of Compositionally Graded NiTi Shape Memory Alloy Laminated Composites Through Hot Roll Bonding and its Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A novel technique for fabricating monolithic functionally graded NiTi shape memory alloy (SMA) laminated hybrid composite has been developed. An excellent metallurgical bonding can be established between two compositionally different NiTi SMAs through spark plasma sintering joining/diffusion bonding followed by hot roll bonding.

Thermal decomposition analysis of simulated high-level liquid waste in cold-cap

open access: yesEPJ Nuclear Sciences & Technologies, 2016
The cold cap floating on top of the molten glass pool in liquid fed joule-heated ceramic melter plays an important role for operation of the vitrification process. A series of such phenomena as evaporation, melting and thermal decomposition of HLLW (high-

Singlet state creation and Universal quantum computation in NMR using Genetic Algorithm [PDF]

open access: yes, 2012
Experimental implementation of a quantum algorithm requires unitary operator decomposition. Here we treat the unitary operator decomposition as an optimization problem and use Genetic Algorithm, a global optimization method inspired by nature's evolutionary process for operator decomposition.

Thermal decomposition of illite

open access: yesMaterials Research, 2004
The effect of heat treatment on illite in air at temperatures ranging from 750 to 1150 °C was studied using the Mössbauer effect in 57Fe. The dependence of the Mössbauer parameters and relative percentage of the radiation absorption area was measured as ...
