Photoaccumulation of Long‐Lived Reactive Electrons in a Microporous Ti(IV) Oxocluster‐Based Metal–Organic Framework for Light and Dark Photocatalysis

open access: yesAdvanced Materials, Volume 38, Issue 8, 6 February 2026.
The microporous Ti12 oxocluster‐based MOF MIP‐177(Ti)‐LT exhibits effective charge separation and long‐lived photogenerated electrons persisting for hours, as revealed by spectroscopy. These electrons cause reversible color changes and enable dark H2 evolution and water splitting, demonstrating remarkable electron storage and redox capability ...

Hemocompatibility of Titanium Nitride

The International Journal of Artificial Organs, 1992
The left ventricular assist device is based on the principle of the Maillard-Wenkel rotative pump. The materials which make up the pump must present particular mechanical, tribological, thermal and chemical properties. Titanium nitride (TiN) because of its surface properties and graphite because of its bulk characteristics have been chosen.

Titanium and titanium nitride contacts to n-type gallium nitride

Semiconductor Science and Technology, 1998
Ti (150 nm), TiN (200 nm) and Ti (5 nm)/TiN (200 nm) contacts have been fabricated on n-type GaN (Si doped , ) and characterized by specific contact resistance measurements and by x-ray photoelectron spectroscopy depth profiling. Ti contacts were annealed between 400 and C in Ar and to observe the effects of annealing environment on ohmic contact ...

Titanium nitride-molybdenum metallizing method for aluminium nitride

Proceedings. Japan IEMT Symposium, Sixth IEEE/CHMT International Electronic Manufacturing Technology Symposium, 1990
A paste containing molybdenum (Mo) and titanium nitride (TiN) powders was printed on aluminium nitride (AlN) substrates and fired. The adhesive strength of substrates metallized with Ni/Au plate was about 25 kg/2.5 mm/sup 2/ and was unchanged after a thermal cycle test.

Creep of silicon nitride-titanium nitride composites

Journal of Materials Science, 1993
The effect of particulate TiN additions (0–50 wt%) on creep behaviour of hot-pressed (5 wt%Y2O3 + 2 wt%Al2O3)-doped silicon nitride (HPSN)-based ceramics was studied. Creep was measured using a four-point bending fixture in air at 1100–1340 °C. At 1100 °C, very low creep rates of HPSN with 0–30 wt% TiN are observed at nominal stresses up to 160 MPa. At

Formation of Titanium Nitride/Titanium Silicide by High Pressure Nitridation in Titanium/Silicon

Japanese Journal of Applied Physics, 1991
Formation of a titanium nitride (TiN) layer by the nitridation of Ti in high-pressure (5.8 atm) ammonium (NH3) ambient is studied. A thick TiN layer is formed in high-pressure nitridation. Solid-phase silicidation reaction occurs at Ti/Si during the nitridation.
