Room-temperature photosynthesis of propane from CO2 with Cu single atoms on vacancy-rich TiO2

Nature Communications, 2023
A photocatalyst for CO2 reduction to C3H8 is prepared by implanting Cu single atoms on vacancy rich TiO2 single layers. Key reaction intermediates, *CHOCO and *CH2OCOCO, are stabilized on the catalyst which promotes C-C bond formation.

Experimental Techniques in Solid State and Low-Temperature Acoustics [PDF]

The Journal of the Acoustical Society of America, 1957
At the present time, solid state acoustics extends over the frequency range from about 1 cy/sec up to ultrasonic frequencies of several hundred Mc/sec. A brief survey of the problems and techniques related with different frequency intervals will be presented.

Application of X-ray Microtomography to Quantify the Liquid Fraction of M2 Steel for Semi-solid Forming process [PDF]

, 2013
Thixoforging, one variant of semi-solid metal processing in which the metallic alloys are processed at low liquid fraction (0.1< Fl < 0.3), is used to produce complex parts with high mechanical properties.

Broadband second harmonic generation in aperiodic nonlinear photonic crystals: 1D projection from 2D Vogel sunflower spiral array

AIP Advances, 2021
The structure of the sunflower head can be used to realize broadband applications in optics. However, this 2D structure, with a ring-shaped reciprocal space, only has a normalized Fourier coefficient peak around 0.033, which leads to a relatively low ...

Surface acoustic wave solid-state rotational micromotor

Applied Physics Letters, 2012
Surface acoustic waves (SAWs) are used to drive a 1 mm diameter rotor at speeds exceeding 9000 rpm and torque of nearly 5 nNm. Unlike recent high-speed SAW rotary motors, however, the present design does not require a fluid coupling layer but interestingly exploits adhesive stiction as an internal preload, a force usually undesirable at these scales ...

Equivalent circuit models of two-layer flexure beams with excitation by temperature, humidity, pressure, piezoelectric or piezomagnetic interactions [PDF]

Journal of Sensors and Sensor Systems, 2014
Two-layer flexure beams often serve as basic transducers in actuators and sensors. In this paper a generalized description of their stimuli-influenced mechanical behavior is derived.

Solid-State Photochemistry in Resonant Acoustic Mixers

Chemistry – A European Journal
Herein, we developed the first photochemical reaction set-up under solid-state conditions using a resonant acoustic mixer (RAM), a novel mechanochemical methodology that eliminates the need for milling media. This innovation outperforms previous approaches in the ball mill under avoidance of milling balls and their related disadvantages.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
