Thin-layer electrolytic iron sulfides synthesized on stainless steel substrates were studied in prototype lithium and lithium-ion
batteries with an electrolyte composed of ethylene carbonate, dimethyl carbonate, and 1 M LiClO4. A two-volt lithium-ion system with electrolytic iron sulfide and LiCoO2 as negative and positive electrodes, respectively, was suggested. The discharge capacity of the prototype system is 350–400
mA h g−1 Fe sulfide. 相似文献

New plasticized polymer electrolytes, based on chlorinated derivatives of polyvinyl chloride, are studied by infrared and impedance spectroscopy. Morphological and electrochemical properties of the electrolytes depend on the nature of the lithium salt and liquid plasticizer and on the technology. Galvanostatic cycling data for lithium batteries based on Li-LiMn2O4 and Li-V6O13 and these electrolytes are presented. 相似文献

The light collection of extruded scintillation strip samples with the help of WLS fibers placed in a longitudinal hole inside of the plates has been measured. The holes are filled with various liquid fillers. Measurements are performed under irradiation by cosmic muons. A method for pumping a liquid filler with a viscosity of more than 10 Pa s into the strip hole with a WLS fiber inside is devised and successfully tested. 相似文献

Previously unknown 3′‐R1‐5‐R2‐spiro[indoline‐3,6′‐[1,2,4]triazino[2,3‐c]quinazoline]‐2,2′‐(7′H)‐diones and their N‐substituted analogues were obtained via reaction of 6‐R1‐3‐(2‐aminophenyl)‐1,2,4‐triazin‐5‐ones with isatin and its substituted derivatives. It was shown that alkylation of 3′‐R1‐5‐R2‐spiro[indoline‐3,6′‐[1,2,4]triazino[2,3‐c]quinazolin]‐2,2′‐(7′H)‐diones by N‐R3‐chloroacetamides or chloroacetonitrile in the presence of а base proceeds by N‐1 atom of isatin fragment. The spectral properties (1H and 13C NMR spectra) of synthesized compounds were studied, and features of spectral patterns were discussed. The high‐effective anticonvulsant and radical scavenging agents among 3′‐R1‐5‐R2‐spiro[indoline‐3,6′‐[1,2,4]triazino[2,3‐c]quinazolin]‐2,2′(7′H)‐diones and their N‐substituted derivatives were detected. It was shown that compounds 2.2 , 2.8 , and 3.1 exceed or compete the activity of the most widely used in modern neurology drug—lamotrigine on the pentylenetetrazole‐induced seizures model. The aforementioned fact may be considered as a reason for further profound study of synthesized compounds using other pathology models. 相似文献

New scintillation counters have been designed and constructed for upgrading the CDF detector at Fermilab Tevatron. A novel
light collection technique using wavelength shifting fibers, together with a high-quality polystyrene-based scintillator UPS
923A, has resulted in compact counters with good and stable light collection efficiency over their lengths extending up to
320 cm. The design, construction, and performance of the counters are presented. Properties of the fibers and the scintillator,
such as light output, light attenuation, decay time, and long-term stability, are investigated. It is found that the polystyrene-based
scintillator, unlike the polyvinyltoluene-based one, has properties more adequate for long-term experiments.

Changes in parameters of complex-plane plots are analyzed for electrolytic Me x S y electrodes (Me = Fe, Co, Ni) and their graphitized analogs contacting electrolyte (ethylene carbonate, dimethyl carbonate, 1 M LiClO4) in the case of degradation in a layout lithium battery at cycle 15. Impedance measurements in the high- and medium-frequency region of complex-plane plots revealed the key role of the surface solid-phase film and also of resistance of charge transfer through the sulfide material/electrolyte interface in degradation of Me x S y electrodes under cycling in the potential range of 2.80?0.02 V vs. Li/Li+. The activation energy is determined for processes of charge transfer through the electrode/electrolyte interface. 相似文献

The etch patterns similar to those found previously for strontium nitrate Sr(NO3)2 were revealed on the surface of barium nitrate Ba(NO3)2 and lead nitrate Pb(NO3)2. The geometry of these patterns is studied. It is suggested that these etch patterns correspond to the translation twins occurring in divalent nitrates at the Pm3 → Pa3 phase transition. 相似文献
