Adsorption coefficients of 2,4-DNT in soils and clay minerals
(2009)
Contamination of soil and water by explosives is widespread and often caused by various military activities. 2,4-DNT is commonly used as a military explosive. This explosive may enter to the environment from the processes ...
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 ...
Bioactivity study and analysis of the volatile constituents and essential oil extracts of Mammea Americana L. fruit by HS-SPME and GC/MS
(2017)
Mammea Americana L. is a tropical fruit tree native from the West Indies with bark, seeds, leaves and flowers that have been reported to contain toxic compounds. However, it is the fruit pulp that results attractive for ...
Enhanced Raman Scattering of TNT on nanoparticles substrates: Ag, Au and Au/Ag Bimetallic colloids prepared by reduction with sodium citrate and hydroxylamine hydrochloride
(2007)
Surface-Enhanced Raman Scattering (SERS) provides extremely high sensitivity, due to increase in the Raman cross-sections of intrinsically very weak scattering events making these events comparable or even better than ...
Desarrollo de método cuantitativo para la determinación del contenido de humedad en el proceso de granulación de un medicamento utilizando la tecnología de infrarrojo cercano
(2011)
The granulation process is one of the most important processes in the manufacture of a pharmaceutical product. This is due to that in this manufacturing step the active ingredient (AI) is mixed with the excipients. One ...
Preparation and study of thin RDX films standards on various substrates deposited by spin coating technology
(2017-05)
The highly energetic material (HEM) hexahydro-1,3,5-trinitro-s-triazine, also known as RDX, has two stable conformational polymorphs at room temperature: α-RDX (molecular conformation of –NO2 groups: axial-axial-equatorial) ...
Consecutive solvent – C60 exchange on (η2– C60) Ir(CO)Cl(PPh3)2 and catalytically significant organometallic reactions on Ir(CO)(PPh3)2Cl(Solvent)
(2010)
The solvent/C60 exchange reactions on (η2 – C60)Ir(CO)(PPh3)2Cl (solvent = benzene and cyclohexane) are biphasic. Plots of absorbance values at 550 nm vs. time are biexponential. Experiments where the reactions were monitored ...
Transmission Raman Spectrometer design for the detection of opioids, concealed chemicals, and biological threats
(2021-07-08)
Raman spectroscopy (RS) is an excellent tool for quantitative and qualitative analysis that can be used to detect and characterize different types of substances. Transmission Raman Spectroscopy (TRS) has been used in ...
Synthesis, characterization and antibacterial properties of pure and Li doped ZnO nanoparticles for alternative water disinfection methods
(2019-07-11)
As a consequence of growing water demand and pollution, water borne disease outbreaks are on the rise and current disinfection methods have shown to be ineffective in inactivating all pathogens during water treatment. Zinc ...
Synthesis of novel ferrocene complexes with androgens vectors, biological activity and their interactions with proteins
(2020-12-11)
Four novel complexes were synthetized by aldol condensation reaction and characterized by different spectroscopic techniques using ferrocenecarboxaldehyde as starting material, and using the hormones ( 3α-hydroxy ...
