2D MXene‐Enabled Unidirectional Flexible Optoelectronic Memristor Toward Energy‐Efficient Neuromorphic Photosensing

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A transparent and flexible ITO/ZnO/TiO2/MXene optoelectronic memristor is developed via low‐temperature solution processing, exhibiting intrinsic self‐rectification and analog synaptic plasticity. The device enables wavelength‐selective photosynaptic response and multimodal learning behaviors, demonstrating strong potential for neuromorphic ...

Effect of C particle size on the mechanism of self-propagation high-temperature synthesis in the Ni-Ti-C system

, 2011
Effect of C particle size on the mechanism of self-propagation high-temperature synthesis (SHS) in the Ni-Ti-C system was investigated. Fine C particle resulted in a traditional mechanism of dissolution-precipitation while coarse C particle made the ...

Preparation of (Ti,Ta)-(C,N) by mechanical alloying

, 2022
S.178-184Ti(C,N) and Ta powders were mechanically alloyed to synthesize the (Ti,Ta)-carbonitride solid solution. As a result of milling, nanocrystalline Ti(C,N) was obtained.

Vacuum Brazing Ti–15–3 with a TiNiNb Braze Alloy

Metals, 2019
Among all types of brazing fillers, Ti-based fillers show satisfactory joint strengths in brazing titanium alloys. However, the major concern in using such fillers is the formation of Cu/Ni/Ti intermetallic compound(s) in the joint.

Redox Potentials for the Synthesis of Cationic Transition Metal Complexes from the Metal and Weak Ligands: A Computational Methodology for Practical Oxidant Choice

European Journal of Inorganic Chemistry, EarlyView.
Identifying synthetic targets: A computational methodology for the estimation of redox potentials of weakly coordinated transition metal complexes was established. Using Born–Fajans–Haber cycles, metal ionization and sublimation energies, solvation energies, and coordinative strength of the ligand were identified as potential‐determining parameters. In

Formation of (Ti,V)(C,N) multicomponent solid solutions by high-pressure sintering of mechanically activated Ti-VN-СNT and Ti-VN-Graphite blends

Materials Research Express
Test samples collected at one-hour intervals during mechanical alloying (MA) of Ti-VN-CNT, Ti-VN-C _GR , and Ti-VN-(CNT + C _GR ) mixtures in a high-energy planetary ball mill were studied using x-ray diffraction, scanning electron microscopy, and energy-

An Experimental Study of Thermal Energy Storage With Phase‐Change Material in a Rectangular Box Filled With Aluminum Foam

Energy Science &Engineering, EarlyView.
We experimentally evaluate a rectangular latent‐heat thermal energy storage box filled with paraffin RT57. Embedding 1–3 aluminum‐foam pieces (ε ≈ 0.89 and 10 PPI) increases effective thermal conductivity, making the temperature field more uniform and accelerating phase change.

Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

Materials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.
