The design, fabrication and testing of micro-fabricated linear and planar colloid thruster arrays
… precision, low thrust efficient space engines. Electrospray propulsion is a serious candidate for this new technological niche. Electrospray thrusters are space propulsion electric engines that take advantage of an electro-hydrodynamic effect known as Taylor cone to produce thrust. When this …

Analytical methods for satellite constellation reconfiguration and reconnaissance using low-thrust manoeuvres
… to be selected. Using a CubeSat equipped with electro-spray propulsion, these manoeuvres can reduce the time to overight by more than 85%, for less than 20 m/s velocity change, when compared with a non-manoeuvring satellite. The second scenario considers a constellation of 24 satellites that …

Sampling, Detection, and Characterization of Endogenous Peptides
… assisted laser desorption ionization (MALDI) and electro spray ionization (ESI), as evidenced by the 2002 Nobel Prize in Chemistry. Using these techniques to create gaseous ions has led to the advent of proteomic and peptidomic studies driven primarily by mass spectrometry (MS) detection. Its …

Analysis of two single trait loci affecting flavonol glycoside accumulations in Arabidopsis thaliana natural variations
… chromatography photo diode array coupling with electro spray -ionization mass spectrometry (HPLC-PDA-ESI-MS) was employed to identify molecular mass of flavonoid aglycones and conjugate sugars. Second, high performance thin layer chromatography (HPTLC) was used to rapidly screen large amounts of …

Determination of Rifapentine and 25-O-desacetyl Rifapentine from 100 µl human breastmilk by LC-MS/MS using protein precipitation and solid phase extraction
… respectively. Ions were produced using Electro spray ionisation (ESI) in the positive ionisation mode. An Agilent Poroshell 120 EC-C18 (4.6 x 50 mm, 2.7 μm) column was used for chromatographic separation using an isocratic method of acetonitrile containing 0.1% formic acid and water …

STRUCTURE–ACTIVITY RELATIONSHIP STUDIES OF HYBRID ANTITUMOR AGENTS FOR THE TREATMENT OF NON-SMALL CELL LUNG CANCER
… as well as in-line liquid chromatography–electro-spray mass spectrometry (LC–ESMS). A cellular imaging study using confocal fluorescence microscopy was performed to study the subcellular distribution of complex 54. The results show higher cellular levels of 54 than of PT-ACRAMTU and …

Development and validation of selective and sensitive LC-MS/MS Methods for determination of para-aminosalicyclic acid and cycloserine/terizidone applicable to clinical studies for the treatment of tuberculosis
… and m/z 95.2 for PAS and the ISTD, respectively. Electro Spray Ionisation (ESI) was used for ion production. Accuracy and precision were assessed over three consecutive, independent runs. The calibration curve fits a quadratic (weighted by 1/x concentration) regression for PAS over the range 0.391 …

Stability of bioactive isoflavones and glycolytic enzymes produced by probiotic bacteria in soy based food during processing and storage
… 4ºC. Liquid chromatography coupled with positive electro spray ionisation tandem mass spectrometry (MS/MS) and diode array detection was used for the quantitation and characterisation of isoflavones in fermented and unfermented soymilk made from soy protein isolate SUPRO 590. Bifidobacterium …
