Improvised design of THz spectrophotometer using LT-GaAs photoconductive antennas, pyroelectric detector and band-pass filters

Development of a Hybrid Piezo Natural Rubber Piezoelectricity and Piezoresistivity Sensor with Magnetic Clusters Made by Electric and Magnetic Field Assistance and Filling with Magnetic Compound Fluid

“…In other words, the MCF rubber is also a pyroelectric material. There have been few reported investigations of pyroelectric rubber comparing to polymers [ 55 , 56 , 57 ]. Therefore MCF rubber is a precious material.…”

Time-Domain Terahertz Spectroscopy and Density Functional Theory Studies of Nitro/Nitrogen-Rich Aryl-Tetrazole Derivatives

“…In view of the importance of the time-domain THz spectroscopy technique and density functional theory (DFT)-based theoretical approach help us to study the structure–properties and correlation of HEMs. , Our group has also explored different types materials such as LT/SIGaAs-based photoconductive antenna and organic and semiconductor crystals for THz generation and its application in time-domain spectroscopy of HEMs. − Because tetrazole derivatives show superior energetic properties as compared to the other five-membered azole moieties because of high contents of nitrogen and higher value of positive heat of formation, their physical properties are comparable with premium explosives like Research department explosive (RDX) and 2,4,6-trinitrotoluene (TNT). − ,, However, most of the reported tetrazole derivatives are very sensitive to impact and friction. − Pellizzeri et al reported the polymorphic characterization of 5­(4-pyridyl)­tetrazole using time-domain THz spectroscopy and solid-state DFT. A deliberation for the synthesis of nitro/nitroamino/azido-substituted aryl tetrazole derivatives, such as 2,6-dinitro-4-(1 H -tetrazol-1-yl)­aniline (C 7 H 5 N 7 O 4 ) (6), N -(2,6-dinitro-4-(1 H -tetrazol-1-yl)­phenyl)­nitramide (C 7 H 4 N 8 O 6 ) (7), 1-(3,4,5-trinitrophenyl)-1 H -tetrazole (C 7 H 3 N 7 O 6 ) (8), and 1-(4-azido-3,5-dinitrophenyl)-1 H -tetrazole (C 7 H 3 N 9 O 4 ) (9) are recently reported because these compounds exhibit better energetic properties than TNT and are comparable to RDX.…”
