Surface enhanced raman scattering of TNT on TiO2 substrates-photodegradation kinetics of explosives
(2007)
The majority of explosives found in antipersonnel and antitank landmines contain 2,4,6- trinitrotoluene (TNT). 2,4-Dinitrotoluene (DNT) is a common manufacturing byproduct in the synthesis and degradation of TNT. The ...
High explosives detection in international mail using See-Through Raman Spectroscopy assisted by multivariate analysis
(2020-12-09)
See-Through Raman Spectroscopy (STRS) was used for the non-invasive, non-destructive sample analysis of high explosives (HEs) in mail envelopes or flats. The method resulted in a safe and rapid analysis of HEs: ammonium ...
Functionalization of titanium surfaces with lysine, aspartic acid, vitamins C and D3: a micro raman study of intermolecular interactions
(2019-05-14)
Titanium (Ti) has been used since 1964 in manufacturing of Ti implants because of its optimal mechanical properties and good biocompatibility. Nevertheless, this biomaterial can have failures due to poor osseointegration ...
Experimental and theoretical study of solubility of 1, 3, 5-trinitrohexahydro-S-triazine (Rdx) In alcohols
(2010)
The solubility of 1,3,5-trinitrohexahydro-s-triazine (RDX) in different alcohols were measured by HPLC, DSC, GC/MS, and NMR. The conformation of RDX in acetone-D6 solution was verified by vibrational studies using Raman ...
Cleaning validation applications using Mid-Infrared quantum cascade laser spectroscopy
(2017)
According to the Recall Root Cause Research (RRCR), an initiative governed by the U.S. Food and Drug Administration (FDA), the contamination of pharmaceutical products is an alarming cause of public concern. During 2015, ...
TNT and MO photodegradation in deionized and salt waters with visible light assisted by photoactivation of modified TiO2
(2020-05-22)
The release of munitions during military combat events or training exercises represents an alarming situation to the marine environment. Since nitroaromatic compounds (NACs) that are released from these weapons remain in ...
Vibrational spectroscopy studies of biomolecular systems: from amino acids to microorganisms
(2014)
Vibrational spectroscopy: infrared and Raman, was applied to the study of two amino acids and ten bacterial strains with the purpose of developing rapid methods of identification and discrimination. Use of spectroscopic ...
Separation, identification, and quantification of explosives using thin layer chromatography coupled to mid-infrared laser spectroscopy
(2019-05-10)
The need for rapid instrumentation and methods for detection and identification of chemical and biological threat agents in national defense and homeland security settings has become an ever more important issue in modern ...
Thermal inkjet technology for the deposition of nanoparticles and Metal-organic framework (Mof): Preparation of sers-active substrates and Mof films for In-situ enhanced raman and infrared detection of harmful contaminants
(2012-12)
The applications of thermal ink-jet printing technology as deposition technique of functional materials such as metal nanoparticles and microporous nickel-oxalate metal organic framework were studied. Highly sensitive ...
Standoff raman spectroscopy system for detection of explosives, chemical warfare agents simulants and toxic industrial compounds
(2008)
In this work a remote Raman system has been designed, assembled and tested for detecting explosives, Toxic Industrial Compounds (TIC) and Chemical Warfare Agents Simulants (CWAS) at laboratory scale up to 7 m target-telescope ...
