Polymorphism of the Transition Metal Oxidotellurates NiTeO4 and CuTe2O5

open access: yesCrystals
As part of crystal growth experiments on transition metal oxidotellurates using chemical vapor transport reactions or hydrothermal conditions, single crystals of NiIITeVIO4 and CuIITeIV2O5 were obtained for the first time in the form of new modifications,

U-Pb geochronology of rutile: deciphering the cooling history of the Oaxacan Complex granulites, southern Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2020
Rutile (TiO2) is a heavy mineral, commonly found as accessory in many lithologies, such as basic igneous rocks, high-grade metamorphic units, as well as a detritus in sedimentary clastic rocks.

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments

open access: yesAdvanced Science, EarlyView.
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.

Pseudorutile-leucoxene-quartz ores of Timan ‒ a new genetic type of titanium raw materials: prospects for industrial development

open access: yesGeoresursy
The two largest deposits of Russia – Yaregskoye and Pizhemskoye belong to the same genetic type; hydrothermal-metamorphic indigenous deposits. They are located in the same Timan structure at a distance of no more than 230 km from each other. According to

Preparation and Photocatalytic Performance of Anatase/Rutile Mixed-Phase TiO2 Nanotubes

open access: yes, 2010
Anatase-dominated anatase/rutile mixed-phase TiO2 nanotubes were prepared by decorating TiO2 on the hydrothermally synthesized TiO2-derived nanotubes via liquid phase deposition and subsequent annealing.

Emergence of Unconventional Magnetic Order in Strain‐Engineered RuO2/TiO2 Superlattices

open access: yesAdvanced Science, EarlyView.
Epitaxial strain activates unconventional magnetism in rutile RuO2, absent in bulk or relaxed RuO2. Polarized neutron reflectometry with atomic‐layer resolution directly reveals finite magnetization confined to RuO2 layers in fully strained RuO2/TiO2 superlattices on TiO2 (110).

Potential for recovery of rutile and other byproducts from western copper tailings [PDF]

open access: yes
"The Bureau of Mines studies tailings samples from 11 large-scale western copper operations to determine the potential for recovery of rutile and other critical and strategic minerals. Up to 15 pounds per short ton (lb/st) ti02 was found in these samples;

H2O-rich rutile as an indicator for modern-style cold subduction [PDF]

open access: yes
The trace-element and isotope geochemistry of rutile are robust tools to determine metamorphic temperatures, age, and host-/source lithologies. The use of rutile as single grain indicator for pressure, temperature, time and composition (P–T–t–X) of the ...

Defect‐Symmetry Engineered Gyroidal Photonic Crystals Achieve Monotonic Modulation of Bandgap Width With a Stable Mid‐Gap

open access: yesAdvanced Science, EarlyView.
Inspired by the twin grain boundary discovered in natural gyroidal networks, a series of gyroid‐derived photonic crystals are constructed based on defect‐symmetry engineering. The new series of structures enables monotonic tuning of the width of the photonic bandgap (PBG) while the central frequency of the PBG maintains stable.
