Design and microwave-assisted synthesis of a novel Mannich base and conazole derivatives and their biological assessment
(Walter De Gruyter Gmbh, 2021)
4-Amino-5-methyl-2,4-dihydro-3H-1,2,4-triazol-3-one (1) was converted to the corresponding Schiff base (2) by treatment with salicylaldehyde. 1,2,4-Triazoles were then converted to the corresponding Mannich bases containing ...
Two new pyridine-2,3-dicarboxylate coordination polymers prepared from zerovalent metal precursor: Syntheses, luminescent and magnetic properties
(Academic Press Inc Elsevier Science, 2014)
Two new K+/Cu(II) and Zn(II) coordination polymers with pyridine-2,3-dicarboxylate (pydc), {K-2[Cu(mu-PYdc)(2)] center dot 3H(2)O}(n) (1) and {[Zn(mu-pydc)(H2O)(4-mim)] center dot H2O}(n) (2) (4-mim=4-methylimidazole) have ...
Qualitative enzymatic detection of organophosphate and carbamate insecticides
(Taylor & Francis Inc, 2020)
In this study, new polymers containing amides (TrisPS-Ntaa, andTrisPS-Ntaa-Fc) were synthesized by condensation reaction for qualitative identification of insecticides. The synthesized polymers, including amides were ...
Copper Phthalocyanine Functionalized Single-Walled Carbon Nanotubes: Thin Films for Optical Detection
(Amer Scientific Publishers, 2015)
Thin films of non-covalently hybridized single-walled carbon nanotubes (SWCNT) and tetra-substituted copper phthalocyanine (CuPcR4) molecules have been produced from their solutions in dimethylformamide (DMF). FTIR spectra ...
EFFICIENT DETERMINATION AND PESTICIDE CONTROL BY MEANS OF IMMOBILIZATION OF ACETYLCHOLINESTERASE
(Soc Chemists Technologists Madeconia, 2017)
Supports involving tetrazole (o/m/p-F-Tet-1H) were prepared to detect pesticides. This novel tetrazole including fluorine in different positions was attached to nanoparticles (2AEPS-(o/m/p-F-Tet-1H)) by a condensation ...
Determination of quercetin in medicinal plants such as rose hip (Rosa canina), bettle (Urticadioica), terebinth (Terebinthina chica) and purslane (Portulace oleracea) using HPLC-MS method
(Chemical Publishing Co., 2012)
A simple and rapid high performance liquid chromatography-mass spectrometry (HPLC-MS) method was developed for the determination of quercetin in four plants and fruits samples which are rose hip (Rosa canina), nettle (Urtica ...
Preparation of analytical columns and HPLC silica-based C-18 packing material synthesis from non-toxic silica source
(Taylor & Francis Inc, 2018)
Studies about stabilization and lowering the activity of the permanent groups of stationary phases that are used in reversed-phase liquid chromatography (RP-HPLC) considerably increased during the last few decades. In gas ...
Formation of the Vilsmeier-Haack complex: the performance of different levels of theory
(Springer, 2011)
Because of discrepancies in the available experimental data, an extensive theoretical investigation of the formation of the Vilsmeier-Haack (VH) complex has been carried out. The barriers to complex formation calculated ...
Synthesis and Antimicrobial, Antiproliferative Evaluation of Novel Quinolone and Conazole Analogues via Conventional and Microwave Techniques
(Wiley-V C H Verlag Gmbh, 2021)
1,2,4-Triazole-3-one (3), acquired from cinnamaldehyde was converted to the corresponding carbox(thio)amides via several steps (6 a-c). Their reaction with sodium hydroxide gave the 1,2,4-triazole derivatives (7 a-c). ...
The effect of carbonization temperature, carbonization time and impregnation ratio on the properties of activated carbon produced from Arundo donax
(Elsevier Science Bv, 2018)
Activated carbons from Arundo donax were obtained by varying impregnation ratio, carbonization time, and carbonization temperature via chemical activation method. By operating impregnation ratio as 1.5 and carbonization ...
