Tailoring the Synthesis of Highly Tetragonal BaTiO₃ Nanoparticles by Regulating Aging Time and Calcination Temperature Using Sol–Gel Route

Crystals
High-quality BaTiO3 nanopowders were synthesized via a sol–gel method using butyl titanate and barium serving as precursors. This study systematically investigates the influence of calcination temperature (600–1000 °C) and gel aging time (2–10 h) on the ...

Distinguishing Intrinsic Descriptors of Grain Boundary Segregation Between Metallic and Non‐Metallic Solutes in BCC Fe via Machine Learning

Materials Genome Engineering Advances
Elemental segregation at grain boundaries (GBs) is widely recognized to influence the mechanical properties of structural materials. However, the intrinsic descriptors governing GB segregation have not been systematically clarified.

Effect of Dispersants on the Properties of Ni Nanopowders Prepared by Liquid Phase Reduction Method

Crystals
Nickel nanoparticles were synthesized via liquid-phase reduction of NiCl2·6H2O with N2H4·H2O. The efficacy of different dispersing agents in preventing agglomeration was systematically compared, establishing a clear processing-dispersion correlation ...

Short-Term Stress-Relaxation Behavior of Nonmetallic Restoratives

, 1975
The rheological behavior of five nonmetallic dental materials was studied. Short-term stress relaxation was found to be strongly dependent on time and temperature. Relaxation behavior of the test materials conformed well to simple mathematical models.

Nonmetallic metal toward a pressure-induced bad-metal state in two-dimensional Cu3LiRu2O6

, 2019
The novel two-dimensional honeycomb layered Cu3LiRu2O6 exhibits Pauli-like paramagnetic and Mott variable range hopping semiconduction behaviors, which contradict the large specific-heat Sommerfeld coefficient for metals, and indicate a possible spin ...
