Comparison of segmentors for liquid—liquid extraction flow-injection analysis
Talanta, 1990The segmentation of two immiscible solvents in a continuous liquid-liquid extraction flow system has been studied with a computer-controlled photometric detection system (resolution time approximately 3 msec). The T-shaped segmentors tested were made of fluoroplastic, glass (A4-T fitting) and a modified glass (A8-T fitting).

Effect of Injection Angle on Liquid Injection in Supersonic Flow
AIAA Journal, 1980The aim of this experimental work was a study of the influence of injection angle on the penetration and breakup of liquid jets in a supersonic airstream. All tests were conducted in the VPI 23-cm Supersonic Wind Tunnel at A/=3.0 with T0-ambient and P0=4.35 atm.

Current status of liquid injectable silicone
Aesthetic Plastic Surgery, 1978Since the inception of the recently concluded formal study, liquid injectable silicone has been both used and abused by many. Reports in both lay and professional literature reflect this experience in the form of a wide range of opinions and judgments regarding the use of this material in corrective surgery.

Liquid-Liquid Extraction Flow Injection Analysis
Critical Reviews in Analytical Chemistry, 1991Abstract In spite of the great improvement in selectivity and sensitivity of modern analytical instrumentation, the classical preconcentration and separation techniques, such as liquid-liquid extraction, ion-exchange chromatography, precipitation, etc., are still widely used to improve analytical measurements, especially in connection with trace and ...

Calculation of the mobility of electrons injected in liquid argon
Physical Review B, 1986A model calculation is carried out in which we evaluate the mobility of electrons injected in liquid argon. Scattering by both phonons and static density fluctuations is taken into account. The calculation for the mobility limited by phonon scattering differs from the usual calculation in crystals by considering both the local changes in the ...

Reaction Injection Moulding (Liquid Injection Moulding)
1992Reaction injection moulding (RIM), alternatively and probably more realistically called liquid injection moulding (LIM), or sometimes high-pressure impingement mixing (HPIM), is essentially a ‘one-shot’ process for moulding polyurethane elastomers by carrying out the reaction and moulding process through the sequence of steps shown in Fig.

Change injection into a liquid dielectric
Annual Report 1963 Conference on Electrical Insulation, 1963As a result of the extensive studies of high-field conduction and flashover in dielectric liquids it is becoming clear that the mechanism of electrical breakdown in such materials is related to the pre-breakdown charge flow. At present it is not known whether the current gives rise to significant heating such that failure occurs due to a thermal run ...

Method for heat injection into a liquid
Review of Scientific Instruments, 1977A novel technique of heat injection into a liquid is presented. Advantages of the technique (based on direct ohmic heating) include the ease with which the apparatus can be set up and its simplicity of operation. Very small heat sources can be fabricated to closely approximate point sources.

Injectable Transformation of Liquid Metal
2018The room temperature liquid metal (RTLM) is emerging as an ideal material for fabricating microdroplets owing to its strong surface tension and easy phase switching property. In this sense, a bottle of liquid metal can be easily transformed into a large amount of tiny liquid metal droplets. Given specific control via external fields such as mechanical,
