(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 ...

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 ...
Pervaporation performance of poly(vinyl alcohol)-graft-poly(N-hydroxymethyl acrylamide) membranes for dehydration of isopropyl alcohol-water mixture
(Wiley, 2021)
In the present work, poly(N-hydroxymethyl acrylamide) grafted poly(vinyl alcohol) (PVA-g-PNHMA) membranes were developed for the dehydration of isopropyl alcohol (IPA) by the use of pervaporation method. The PVA-g-PNHMA ...
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 ...
