Synthesis, Characterization and Application of Lithium intercalated boron nitride nanotubes

ABSTRACT: Synthesis of Lithium Intercalated Boron Nitride Nanotubes (Li-BNNT) was conducted in an attempt to gain access to their promising applications for electronics, lithium batteries, hydrogen storage, and supercapacitors. Through a series of reactions pure nanotubes intercalated with lithium are expected to show in the product. A variety of reactions are engineered to create optimal conditions for the product and the reaction is conducted at 700º or 800ºC with zinc acting as a catalyst. The products were then purified using hexane and characterized using Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and Energy-dispersive X-ray Spectroscopy (EDX). Further purification, functionalization, and application will be performed to access the promising applications that Li-BNNT offers.B.A. (Bachelor of Arts

Smart Metro - Rail System

Railway transport system has proved to be a very sturdy and convenient mode of transport over the centuries. It still serves as the economic and most efficient means of mass transport in many countries. It is a widespread practice even today that most operations are manually carried out, leading to several dangerous accidents and mismanagement of the system. When it comes to the matter of scores of lives, error margin is of utmost importance to ensure an efficient and safe mode of travel. There is an utter need for a system that provides automation of the critical systems that play a pivotal role in the smooth functioning. The focus remains on certain key functions including locomotion, data logging for position, speed and health of he locomotive. This can increase the safety levels, while also reducing the time for relief in-case of unfortunate emergencies

New Boron Analogues of Pyrophosphates and Deoxynucleoside Boranophosphates

Tetraethyldicyanoborane pyrophosphate (2) and 3'-(diethylphosphite-cyanoborano)-5'-dimethoxytrityl.N4-benzoyl-deoxycytidine (3) have been synthesized in 70% and 76% yields, respectively. The compatibility of the substituted boranophosphates with common protecting groups is hereby demonstrated

Carborane‐Containing Matrix Metalloprotease (MMP) Ligands as Candidates for Boron Neutron‐Capture Therapy (BNCT)

Based on the previously reported potent and selective sulfone hydroxamate inhibitors SC‐76276, SC‐78080 (SD‐2590), and SC‐77964, potent MMP inhibitors have been designed and synthesized to append a boron‐rich carborane cluster by employing click chemistry to target tumor cells that are known to upregulate gelatinases. Docking against MMP‐2 suggests binding involving the hydroxamate zinc‐binding group, key H‐bonds by the sulfone moiety with the peptide backbone residues Leu82 and Leu83, and a hydrophobic interaction with the deep P1’ pocket. The more potent of the two triazole regioisomers exhibits an IC50 of 3.7 nM versus MMP‐2 and IC50 of 46 nM versus MMP‐9

[η5-2,3-Bis(trimethylsilyl)-2,3-dicarba-nido-hexaborane(2−)]chlorido(N,N,N′,N′-tetramethylethylenediamine)dysprosium(III)

The structure of the title compound, [Dy(C8H22B4Si2)Cl(C6H16N2)], reveals that a center of symmetry exists within the dimeric half-sandwich units. Within each half-sandwich, the DyIII ion is coordinated by the five-membered ring of the carborane, tetramethylethyl­enediamine and the chloride ion
