Synthesis gas as a fuel for internal combustion engines in transportation
(2022-05-01)The adverse environmental impact of fossil fuel combustion in engines has motivated research towards using alternative low-carbon fuels. In recent years, there has been an increased interest in studying the combustion of ... -
Synthesis of benzofurans and benzopyrans
(University of Hertfordshire, 2002)Syntheses of 2,3-dihydrobenzofurans and 3,4-dihydrobenzopyrans normally involve several stages, therefore efficient syntheses of these compounds are desirable. A number of 3,4-dihydrobenzopyrans derivatives were prepared ... -
Synthesis of bioinorganic antimicrobial peptide nanoparticles with potential therapeutic properties
(2008)Amphiphilicity and cationicity are properties shared between antimicrobial peptides and proteins that catalyze biomineralization reactions. Merging these two functionalities, we demonstrate a reaction where a cationic ... -
Synthesis of conformationally constrained analogues of BRL32872 : Determination of stereochemistry and related pharmacological properties
(1997-08-05)2-Azabicyclo[2.2.2]octane derivatives have been used as conformationally constrained structure of BRL-32872, in order to investigate the effect of molecular flexibility towards class III and class IV antiarrhythmic properties. ... -
Synthesis of DNA-directed pyrrolidinyl and piperidinyl confined alkylating chloroalkylaminoanthraquinones : potential for development of tumor-selective N-oxides
(2006)A novel series of 1,4-disubstituted chloroethylaminoanthraquinones, containing alkylating chloroethylamino functionalities as part of a rigid piperidinyl or pyrrolidinyl ring-system, have been prepared. The target compounds ... -
Synthesis of Fock states via beam splitters
(1997)An idea to synthesize Fock states for pulsed light beams is presented. It uses an array of beam splitters with several input ports which are fed with single-photon Fock states. Detectors survey all but one output port of ... -
Synthesis of genomic and subgenomic RNAs by a membrane-bound RNA-dependent RNA polymerase isolated from oat plants infected with cereal yellow dwarf virus
(2006-11)A membrane-bound RNA-dependent RNA polymerase (RdRp) complex was isolated by differential sedimentation from oat plants infected with cereal yellow dwarf virus (CYDV). When incubated with P-32-labelled UTP, unlabelled ATP, ... -
Synthesis of mucoadhesive thiol-bearing microgels from 2-(acetylthio) ethylacrylate and 2-hydroxyethylmethacrylate : novel drug delivery systems for chemotherapeutic agents to the bladder
(2015-07-21)Thiol-bearing microgels have been synthesised from copolymerisation of 2-(acetylthio)ethylacrylate and 2-hydroxyethylmethacrylate, and subsequent deprotection using sodium thiomethoxide. The concentration of thiol groups ... -
The synthesis of potential anti parasitic compounds
(University of Hertfordshire, 2001)Novel members of a homologous series of N', N'-di-(2,6-dinitro-4-trifluoromethylphenyl) diamine dimers related to the anti-malarial compound trifluralin (2,6-dinitro-(N, Ndipropylamino- 4-trifluoromethyl)benzene) have ... -
Synthesis of qualitative research studies regarding the factors surrounding UK critical care trial infrastructure
(2019-12-22)Conducting clinical trials in critical care is integral to improving patient care. Unique practical and ethical considerations exist in this patient population that make patient recruitment challenging, including narrow ... -
Synthesis, biological evaluation, and SAR studies of 14β-phenylacetyl substituted 17-cyclopropylmethyl-7, 8-dihydronoroxymorphinones derivatives : Ligands with mixed NOP and opioid receptor profile
(2018-09-19)A series of 14β-acyl substituted 17-cyclopropylmethyl-7,8-dihydronoroxymorphinone compounds has been synthesized and evaluated for affinity and efficacy for mu (MOP), kappa (KOP), and delta (DOP) opioid receptors and ... -
Synthesis, characterization and biological evaluation of benzo[d]isothiazole ring systems, fused to nitrogen heterocycles
(University of Hertfordshire, 2014-09-19)We have developed a simple and efficient synthetic route, starting from easily available starting materials, to the novel ring system benzo[4,5]isothiazolo[2,3-a]pyrazine-6,6-dioxide. A series of chalcones were synthesized ... -
Synthesis, luminescence and phase composition of samarium-doped zinc phosphate glass ceramics
(2013-06)Samarium doped zinc phosphates ySm2O3–(72–y)ZnO–28P2O5 where y varies between 0·03 and 0·28 mol% were synthesised using the melt quenching method and investigated by photoluminescence, powder x-ray diffraction, differential ... -
Synthetic 26Al emission from galactic-scale superbubble simulations
(2019-10-03)Emission from the radioactive trace element 26Al has been observed throughout the Milky Way with the COMPTEL and INTEGRAL satellites. In particular the Doppler shifts measured with INTEGRAL connect 26Al with superbubbles, ... -
Synthetic cannabinoid use in a case series of patients with psychosis presenting to acute psychiatric settings : Clinical presentation and management issues
