The application of antimony sulfide (Sb2S3) has been limited mainly to the energy storage and photoelectric conversion fields. However, in this work, Sb2S3 is extended field electromagnetic (EM) wave absorption for first time. High-permittivity single-crystal nanorods were prepared successfully exhibited excellent performance, with a low reflection loss −65.9 dB (13.0 GHz, 3.8 mm) an ultra-wide...

OBJECTIVE To determine whether antimony may be detected in the urine during infancy and early childhood and its association with passive exposure to tobacco smoke, as assessed by urinary cotinine. DESIGN Analysis of spare aliquots of urine collected from infants participating in studies of respiratory function and passive smoking. Urinary antimony was assayed using inductively coupled plasma ...

Oesophageal pH monitoring data are influenced by numerous patient or technique related factors, or both. In this study, data recorded with glass microelectrodes or antimony electrodes, both with external cutaneous Ag/AgCl reference electrodes, connected to two different recording devices are compared. Pearson correlation coefficients regarding the reflux index (% of the investigation time with ...

Abstract A total of 4512 rhizobacteria were isolated at three stages of plant growth from Achillea ageratum colonizing a polluted site with an antimony concentration gradient. For 222 of these isolates auxin production (aux(+)) was verified in vitro. The percentage of aux(+) isolates increased with soil antimony concentration, as well as with plant growth stage. An amplified rDNA restriction an...

antimony is a toxic heavy metal for plants, animals and human being. considering its effects on plants growth, different concentrations on watermelon growth and development were studied. the experiment was established on a factorial experiment based on a completely randomized design with 3 replications. the seedlings were grown hydroponically in nutrient solution containing sb-edta (0, 0.25, 0....

an additional, slightly delayed onset of gastro-intestinal disturbance including abdominal pain and persistent anorexia. Urine antimony estimations revealed a concentration in excess of i mg./litre in these five men. Environmental measurements suggest that they were briefly exposed to air containing up to 146 mg. hydrochloric acid and 73 mg. antimony per m.3 expressed as the metal. These findin...

Zinc dialkyldithiophosphate additives are used to control wear and inhibit oxidation in almost all engine oils as well as many other types of lubricant. They limit wear primarily by forming a thick, protective, phosphate glass-based tribofilm on rubbing surfaces. This film formation can occur at low temperatures and is relatively indifferent to the chemical nature of the substrate. There has be...
