SYSTEM AND METHOD FOR BUILDING CONTAINER CLUSTER

The present disclosure provides a method and container management system for building container cluster. The container management system based on user requirement may automate hardening of operating system and configure network and storage for adding new container. The container management system obtains and configures load balancer VIP without any manual intervention. Thereafter, the container management system performs end-to-end validation by deploying test application and validating the test application. Thus, the present disclosure reduces time consumption for building container clusters based on the user requirement

Synthesis of Black Phosphorene Quantum Dots from Red Phosphorus

Phosphorene quantum dots (PQDs) are most commonly derived from high-cost black phosphorus, while previous syntheses from the low-cost red phosphorus (Pred) allotrope are highly oxidised. Herein, we present an intrinsically scalable method to producing high quality PQDs, by first ball-milling Pred to create nanocrystalline Pblack and subsequent reductive etching using lithium electride solvated in liquid ammonia. The resultant ~25 nm PQDs are crystalline with low oxygen content, and spontaneously soluble as individualized monolayers in tertiary amide solvents, as directly imaged by liquid-phase transmission electron microscopy. This new method presents a scalable route to producing quantities of high quality PQDs for academic and industrial applications

Preparation of composite electrodes with carbon nanotubes for lithium-ion batteries by low-energy ball milling

Some of the prospective electrode materials for lithium-ion batteries are known to have electronic transport limitations preventing them from being used in the electrodes directly. In many cases, however, these materials may become practical if they are applied in the form of nanocomposites with a carbon component, e.g. via incorporating nanoparticles of the phase of interest into a conducting network of carbon nanotubes. A simple way to prepare oxide-carbon nanotube composites suitable for the electrodes of lithium-ion batteries is presented in this paper. The method is based on low-energy ball milling. An electrochemically active but insulating phase of LiFeTiO4 is used as a test material. It is demonstrated that the LiFeTiO4-carbon nanotube composite is not only capable of having significantly higher capacity (∼105-120 mA h g-1vs. the capacity of ∼65-70 mA h g -1 for the LiFeTiO4 nanoparticles) at a slow current rate but may also operate at reasonably high current rates. © the Partner Organisations 2014

Understanding the Cyclic (In)stability and the Effects of Presence of a Stable Conducting Network on the Electrochemical Performances of Na2Ti3O7

Despite being a promising anode material for the Na-ion battery system, Na-titanate (viz., Na2Ti3O7) lacks in terms of cyclic stability; the cause(s) for which are under debate. Against this backdrop, through electrochemical measurements and insitu synchrotron X-ray diffraction studies, the present work develops insights into the aspects concerning electrochemical reversibility of the fully sodiated phase (i.e., Na4Ti3O7), possible occurrence of irreversible reactions in Na-ion cells, influences of the same towards cyclic instability, and a strategy towards alleviating this problem. The insitu studies rule out (in)stability/(ir)reversibility of Na4Ti3O7 as being a major cause for the capacity fade; rather they indicate the formation of 'impurity' phase(s) due to reaction with the electrolyte. Incorporation of multi-walled carbon nanotubes (MWCNTs; uniformly 'wrapping' the rod-shaped Na2Ti3O7 particles) significantly improved the cyclic stability (ca. 78% reversible capacity retention after 50 cycles, as compared to ca. 6% without MWCNTs) and rate capability (with nearly flat potential plateaus at 5C). The same suppressed the increase in charge-transfer resistance upon cycling by an order of magnitude and also changed the sodiation reaction from being primarily surface to diffusion controlled. Correlation of the results/analysis indicate that, in the absence of a stable conducting network, loss in electrical connectivity owing to the formation of insulating/passivating (surface) phase(s) is the major cause for capacity fade of Na2Ti3O7

Ionic liquids-promoted addition of arylsulfinic acids to p-quinones: a green synthesis of diaryl sulfones

Arylsulfinic acids undergo smooth conjugate addition to p-quinones in air- and moisture-stable second generation room temperature ionic liquid [bmim]BF4 under mild conditions to produce the corresponding arylsulfonylhydroquinones in excellent yields with high selectivity. In this reaction, ionic liquid plays the dual role as the solvent and the catalyst. The quinones show enhanced reactivity in ionic liquid thereby reducing the reaction times and improving the yields significantly. The presence of ionic liquids helps to avoid the use of either acid or base catalysts for this conversion. The recovered ionic liquid was reused for four to five times with consistent activity

Lithium storage in disordered graphitic materials: a semi-quantitative study of the relationship between structure disordering and capacity.

The application of the graphitic anode is restricted by its low theoretical specific capacity of 372 mA h g(-1). Higher capacity can be achieved in the graphitic anode by modifying its structure, but the detailed storage mechanism is still not clear. In this work, the mechanism of the lithium storage in a disordered graphitic structure has been systematically studied. It is found that the enhanced capacity of the distorted graphitic structure does not come from lithium-intercalation, but through a capacitive process, which depends on the disordering degree and the porous structure

Bilateral symmetrical periprosthetic (mirror) fractures of knee fixed with dual plating technique

AbstractIntroductionPeriprosthetic fracture following total knee arthroplasty is a potentially serious condition. Here we report a case of bilaterally symmetrical (mirror) fracture of supracondylar area following trivial trauma.Presentation of caseBoth fractures were OTA 33A2 and according to Rorabeck classification they were type II. Both fractures were fixed by dual plating technique using non locking plates. Intra operative fracture site biopsy revealed marked osteopenia and hence the patient was treated for osteoporosis.DiscussionBoth fractures united well at 14 weeks. At final follow up of 6 years there were no radiological signs of implant loosening and the patient was able to walk without any aids and had a range of 80° and 60° flexion in the right and left knees respectively.ConclusionWe conclude that in the pre locking plate's era such difficult case has been successfully managed by dual plating technique
