Psychostimulant treatment uniquely reduces left uncinate fasciculus microstructural integrity in ADHD youth with a familial risk for bipolar I disorder: a 12‐week DTI study

Journal of Child Psychology and Psychiatry, Volume 67, Issue 5, Page 696-706, May 2026.
Background Bipolar I disorder (BD) is associated with reduced white matter microstructural integrity in the uncinate fasciculus (UF), a primary fiber tract connecting frontolimbic systems. Although familial history for BD, attention‐deficit/hyperactivity disorder (ADHD), and psychostimulants are important risk factors implicated in BD pathoetiology ...

Effect of Immediate Quenching after As-sintered on Microstructure of WC Phase and Strength of WC-14mass%TiC-8mass%Co

WC-14%TiC-8%Co cemented carbide of as-sintered was immediately quenched. In comparison with conventional sintered specimen, the strengths of the quenched cemented carbides were increased by 20.2%～32.8%.

Characterization of WC-VC-Co and WC-VC-TiC-Co hardmetals

, 2007
This thesis contains the results of a study focused on cubic carbide and carbonitride grain growth retardation in hardmetals. Large additions of VC, or VC and TiC, or (W,V)C were made to the WC-Co hardmetal, which was then sintered in vacuum or nitrogen.
