Abstract
Soft matter provides diverse opportunities for the development of electrolytes for all solid state lithium batteries. Here we review soft matter solid electrolytes for lithium batteriesthat are primarily obtained starting from liquid electrolytic systems. This concept of solid electrolyte synthesis from liquid is significantly different from prevalent approaches. The novelty of our approach is discussed in the light of various fundamental issues and in relation to its application to rechargeable lithium batteries. 相似文献12.

A liquid chromatographic method with photodiode-array detection has been developed for differentiation of seven genotypes of Lippia gracilis Schauer, originated from Sergipe state (named 106 to 110) and from Bahia state (201 and 202), cultivated and collected in the rural campus of the Federal University of Sergipe. For a comparative analysis of the fingerprint chromatograms, chemometric tools were applied with exploratory methods. The genotypes were differentiated and their relationship with original place was established (Sergipe and Bahia states) by principal component analysis of the fingerprint chromatograms of both leaves and stem samples. 相似文献

The regio- and diastereoselective synthesis of pyrrolidine derivatives through 1,3-dipolar cycloaddition of an azomethine ylide and dipolarophile mediated by KF/Al2O3, a versatile solid supported reagent, is reported. KF/Al2O3 is sufficiently basic such that it can deprotonate α-imino esters to generate azomethine ylides and it also functions as a solid supported catalyst leading to the cycloadduct rather than the Michael adduct. 相似文献

The effects of oral intake of hydroxyapatite nanoparticles (HApNPs) were investigated on growth, development and behaviour of Drosophila. The Drosophila responses to various concentrations of HApNPs were compared. At lower concentrations, i.e. 5 mg L?1 more amount of oxidative stress was produced than that of highest concentration, i.e. 80 mg L?1. The increased amounts of oxidative stress reflect a higher amount of ROS production and increased cell damage within the larval gut. HApNPs was further shown to interfere with the calcium and phosphorus absorption pathway. Besides all these damage, HApNPs causes developmental delay in the late third instar larvae. The most significant anomaly was observed in pupae count, fly hatching after the feeding of HApNPs. Flies hatched from treated vials have decreased body weight with defective walking behaviour. Hatched flies have a phenotypic defect in the wing, eye and thorax of the bristles. Along with these changes, the adult fly becomes more prone towards stress. The findings hint that HApNPs persuade noxious effects and alter the development, structure, function and behaviour of the fly in a concentration-dependent manner. 相似文献

The structural organization of the eyes belonging to 12 winged male and 12 wingless female Orgyia antiqua moths, exposed for 1 h to UV-radiation (lambda(max)=351 nm) of 1.4 kW/m2, was compared with that of 12 male and 12 female non-irradiated control specimens. Following the UV-exposure, the screening pigments were found in a position indicative of extreme light-adaptation. Extensive formations of vesicles along the perimeter of the cones as well as disintegrating ER in the cone cytoplasm were noticeable, especially in the eye of the female. On the retinal side of the clearzone, the microvilli of the rhabdoms had become affected by the UV in characteristic ways: in the male eye, retinal cell damage in the form of microvillar swellings and disintegrations were largely confined to just two cells per ommatidium, placed opposite to each other. The female eye, once again, exhibited greater vulnerability and more widespread microvillar disruptions that affected all of the ommatidial retinula cells. The greater resistance of the eye of the male to an exposure with UV makes sense, if we consider the consequences of the retinal damage, which would clearly be a more severe handicap for an actively flying individual than for an almost sedentary one like the wingless female. 相似文献

Dehydration of oximes and amides to nitriles was carried out using the AlCl(3) x 6H(2)O/KI/H(2)O/CH(3)CN system. It produced isoquinoline derivatives 8a-c (Bischler Naperialski reaction) when reacted with amides 7a-c in hydrated media. Also, the keto oximes produced anilides (Beckmann rearrangement) with the system under the same reaction conditions. 相似文献

Three meso‐ester boron dipyrromethene (BODIPY) dyes have been synthesized and functionalized with aggregation‐induced emission (AIE)‐active tetraphenylethene or triphenylethene moieties. It was found that functionalizing at the different positions of the BODIPY core resulted in the final dye having different emission properties in response to aggregation: from aggregation‐induced quenching (ACQ) to being AIE active. X‐ray crystallographic analysis was thus performed to provide an explanation for these differences. 相似文献

Iridium(I) salicylaldiminato-cyclooctadiene complexes, Ir(-o-O-C6H4-CHN-R)(cod) (R = CH2Ph (1), Ph (2); cod = 1,5-cyclooctadiene), have been prepared, characterized and used as catalysts for arylborylation via C-H activation. With 1 as a catalyst, isolated yields of up to 91% has been achieved for the borylation of benzene by bis(pinacolato)diboron in the presence of tetra-2-pyridinylpyrazine and an ionic liquid. The catalytic system could be recycled for at least three times without loss of activity. 相似文献

Ligand‐Induced Evolution of Intrinsic Fluorescence and Catalytic Activity from Cobalt Ferrite Nanoparticles 下载免费PDF全文
To develop CoFe2O4 as magneto‐fluorescent nanoparticles (NPs) for biomedical applications, it would be advantageous to identify any intrinsic fluorescence of this important magnetic material by simply adjusting the surface chemistry of the NPs themselves. Herein, we demonstrate that intrinsic multicolor fluorescence, covering the whole visible region, can be induced by facile functionalization of CoFe2O4 NPs with Na‐tartrate. Moreover, the functionalized CoFe2O4 NPs also show unprecedented catalytic efficiency in the degradation of both biologically and environmentally harmful dyes, pioneering the potential application of these NPs in therapeutics and wastewater treatment. Detailed investigation through various spectroscopic tools unveils the story behind the emergence of this unique optical property of CoFe2O4 NPs upon functionalization with tartrate ligands. We believe our developed multifunctional CoFe2O4 NPs hold great promise for advanced biomedical and technological applications. 相似文献
