Operando Magic Angle Spinning Solid‐State NMR Spectroscopy of Methanol Photoreforming Over Titania‐Coated Silica Monoliths

Chemistry – A European Journal, EarlyView.
Photoreforming of methanol is followed in real time by solid‐state Magic Angle Spinning NMR. The transparent sapphire sample holder is irradiated by four LEDs at 11.5 kHz MAS. Efficient light penetration into the sample volume is ensured by silica monoliths with a network of macropores, coated with TiO2, and enhancing light penetration by a factor of ...

Astrometry of the main satellites of Uranus: 18 years of observations

, 2015
We determine accurate positions of the main satellites of Uranus: Miranda, Ariel, Umbriel, Titania, and Oberon. Positions of Uranus, as derived from those of these satellites, are also determined. The observational period spans from 1992 to 2011.

An investigation into the effect of thickness of titanium dioxide and gold-silver nanoparticle titanium dioxide composite thin-films on photocatalytic activity and photo-induced oxygen production in a sacrificial system [PDF]

, 2011
Thin films of titanium dioxide and titanium dioxide with incorporated gold and silver nanoparticles were deposited onto glass microscope slides, steel and titanium foil coupons by two sol–gel dip-coating methods.

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?

Geological Journal, EarlyView.
The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...

OPTICAL PROPERTIES OF ANODIC TITANIA AND IT'S APPLICATION IN MAXILLOFACIAL SURGERY

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
Studying of anodic titania formation has showen that anodization forming factor at low anodic voltages is 3,3 nm/V, while at high anodic voltages it’s value decreases till 1,5 nm/V. The investigation of optical properties of anodic titania has showed the

Silica suspension and coating developments for Advanced LIGO [PDF]

, 2006
The proposed upgrade to the LIGO detectors to form the Advanced LIGO detector system is intended to incorporate a low thermal noise monolithic fused silica final stage test mass suspension based on developments of the GEO 600 suspension design. This will

Enhanced blue emission in silica‐confined mixed‐halide perovskite quantum dots via releasing residual stress

InfoMat, EarlyView.
Residual tensile stress is identified as a key factor responsible for the low luminous efficiency in silica‐confined blue‐emitting CsPb(Cl/Br)3 quantum dots. A hydrothermal treatment enables stress release in these quantum dots and significantly enhances their luminous efficiency.
