Template-synthesized V2O5 nanostructured electrodes (see Figure and cover) are used as tools for fundamental investigations into the poor low-temperature performance of Li-ion batteries. The consisted nanofibers V2O5, by controlling dimensions it has been determined that rate-limiting factor at low temperatures is concentration polarization Li ion in electrode material.
Abstract Multi‐walled carbon nanotube (MWCNT)/silicon nanocomposites obtained by a grafting technique using the diazonium chemistry are used to prepare silicon negative electrodes for lithium‐ion batteries. The covalent bonding of two compounds is via mono‐ and multi‐layers phenyl bridges, leading an ideal dispersion MWCNTs nanoparticles that bound together. presence close enhances electronic pathway active material particles probably helps prevent decrepitation upon repeated lithium...
Abstract Nanothermites are the most important family of energetic materials in contemporary pyrotechnics. This article traces main research which was carried out this still recent domain and challenges that remain to be overcome. The academic effort past two decades has brought nanothermites from status laboratory curiosities one pre‐industrial materials. Different aspects discussed order provide valuable information scientists experimenting domain. Experimental details on preparation...
p-Phenylenediamine is used to successively generate two aryl radicals that are required link silicon nanoparticles graphite flakes by a phenyl bridge and form new silicon/graphite nanocomposites (see image). Such covalent grafting technique enhances the cycling ability gravimetric capacity of nano composite-based electrode in lithium-ion battery. Detailed facts importance specialist readers published as "Supporting Information". documents peer-reviewed, but not copy-edited or typeset. They...
In this paper, polydimethylsiloxane (PDMS) with a superhydrophobic surface was generated by the combination of an acid corrosion followed covalent grafting highly fluorinated monolayer. The performed H2SO4 or HF, and more effective concentrated H2SO4. resulting had contact angle water 135 degrees. All acid-treated samples were then functionalized triethoxyaminopropylsilane reaction semifluorinated chlorides, via formation amide bond, directly commercially available silane,...
The mixing of aluminum nanoparticles with a metal containing oxidizer (here, WO3 or Bi2(SO4)3) gives reactive materials called nanothermites. In this research, nanothermites were combined high explosive (RDX) to prepare energetic nanocomposites. These smart nanomaterials have higher performances and are much less hazardous than primary explosives. Their flame propagation velocity can be tuned from 0.2 3.5 km/s, through their content. They used initiate the detonation explosive,...
Automation of retail industry is calling for the low cost solution due to its sheer size and varied needs. Printed electronics offers a great potential in addressing needs point-of-sales, inventory management self-service, particular radio frequency identification (RFID) systems consisting printed components. Screen Ultra high (UHF) RFID reader antennas have been investigated this work their application potentials retails achieving easy-implementation cost. The results obtained clearly...
4-Carboxyphenyl groups are covalently grafted onto graphene oxide via diazonium chemistry for studying their role on the adsorption of iron nanoparticles. The nanoparticles deposited a novel phase-transfer approach involving specific interactions at interface between two immiscible solvents. increased density and homogeneous distribution surface carboxyl moieties enable preparation nanocomposite with improved loading. Structure-properties relationships investigated by analysing...
The integration of nanostructured materials in defense systems is expected to improve their performance terms power, safety, and reliability. That why considerable research effort has been undertaken by major military powers worldwide this domain. first important step was develop the production capacities organic explosives state fine powders with submicron nanosized particle size distributions. Spray Flash Evaporation (SFE) process, which a unique method for producing such materials,...
Herein, we report the kilogram-scale synthesis of CD08108, a novel MC1R agonist. This has been developed to produce first batches this compound for preclinical and clinical studies. Two amido couplings were used synthesize backbone API. Improvements have made isolate crystalline intermediates remove all column chromatographic steps. Crystallization final API was monitored by DSC in-process control during slurry ripening amorphous suspension hydrochloride salt.

Abstract The pyrotechnic compositions made up of potassium perchlorate (KClO 4 ) and titanium hydride (TiH 2 ), known as THKP, have a fast deflagration velocity (∼500 m/s), along with low sensitivity high stability. In this research, new kind THKP was formulated from submicron powder KClO (50–400 nm) prepared by the Spray Flash‐Evaporation (SFE) process. use fine not only ensures better oxidation TiH , but also leads to transition detonation in THKP. This is observed loose powders placed...
The goal of the protocol described in this article is to prepare aluminothermic compositions (nanothermites) form porous, monolithic objects. Nanothermites are combustible materials made up inorganic fuel and an oxidizer. In nanothermite foams, aluminum phosphate tungsten trioxide oxidizing moieties. highest flame propagation velocities (FPVs) nanothermites observed loose powders FPVs strongly decreased by pelletizing powders. From a physical standpoint, metastable systems. Their properties...
