THz Gas Sensing Using Terahertz Time-Domain Spectroscopy with Ceramic Architecture.

Ceramic architectures based on chemical vapor deposition (CVD) are used to create unique crystal structures, morphologies, and properties. This study proposed room-temperature THz gas sensing using terahertz time-domain spectroscopy (THz-TDS) with ceramic architectures. We synthesized ceramic films on porous glass.

Exchange-correlation interaction and AO-hybridization of alkali-metal atomic clusters.

The structure of alkali-metal atomic clusters is optimized with B3P86 hybrid functional for the highest spin state as well as with B3LYP hybrid functional for the lowest spin state. A dramatic change from plane to solid occurs in the highest spin state when the number of constituent atoms is four. The binding, exchange, and correlation energies are evaluated for both the highest and lowest spin states.

Sticking probability of CN(X2Σ+) radicals onto amorphous carbon nitride films formed from the decomposition of BrCN induced by the microwave discharge flow of Ar.

The sticking probability, s, of CN(X(2)Σ(+)) radicals onto amorphous carbon nitride (a-CN(x)) films with high [N]/([N]+[C]) ratios (≤0.5) was evaluated. CN(X(2)Σ(+)) radicals were generated from the decomposition of BrCN with the microwave discharge flow of Ar in the two experimental configurations, I and II, where the distance between the tip of the nozzle introducing BrCN is close (≈10 mm) to and distant (≈0.

MDCT demonstration of intraarticular gas in the glenohumeral joint and sternoclavicular joint with reference to arm position.

Purpose: Our purpose was to investigate the frequency of intraarticular gas in the glenohumeral joint and sternoclavicular joint, along with the influence of the patient's arm position.

Materials And Methods: Multidetector-row computed tomography (MDCT) scan on a total of 104 healthy subjects was investigated retrospectively. Raised-arm and lowered-arm positions were used sequentially, and the presence of intraarticular gas was investigated.

Measurements of density and sticking probability of CN(X(2)Sigma(+)) radicals by laser-induced fluorescence spectroscopy.

CN(X(2)Sigma(+)) radicals were produced by the decomposition of BrCN with the microwave discharge flow of Ar under the conditions of Ar pressure in the range of 0.40-0.70 Torr.
