Abstract: This paper studies the luminescence-sensing properties of 1D porous zinc coordination polymer [Zn(3-tba)2]ꞏDMA (1, 3-
Htba = 3-(4H-1,2,4-triazol-4-yl)benzoic acid, DMA = N,N-dimethylacetamide). The systematic luminescence experiments
indicate that it can be potentially used as a fast-response fluorescence sensor for the sensitive detection of nitrobenzene and
Fe3+ ion through drastic fluorescence quenching. Moreover, the quenching mechanisms of 1 towards nitrobenzene and Fe3+
have also been investigated.

Abstract: A green light promoted, facile, one-pot approach for the synthesis of biologically important 6-(substituted/unsubstituted benzylthio)-3-phenyl-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazole 6a-m has been developed. New synthetic approach for the preparation of tailor-made synthesis of triazolo [3,4-b] [1,3,4] thiadiazol derivatives 6a-m are in extremely high demand as they display significant potent activity against fungal strains as well as on mutant strains. Herein, we have designed an efficient, cheap and easy photo-induced synthetic strategy to obtain the target compound with excellent yield. Compounds 6a-m have been evaluated in vitro for their fungitoxicities against Penicillium citrinum and Fusarium oxysporum. All the synthesized compounds have been found to be antifungal active. Among them, activities of some of the compounds displayed are comparable with that of the commercial fungicide griseofulvin and Dithane M-45. Structure activity relationships (SAR) for the screened compounds have been discussed.

Authors: Savaniya, Nikhil P; Khakhariya, Amit D; Pankhaniya, Priyanka P; Ladva, Kartik D
Abstract: Herein is described an account of research work that focuses on synthesis of some novel α,β-unsaturated compounds. To
afford 2-(3-(2-cyano-2-(p-tolylamino)vinyl)-1H-indol-1-yl)-N-arylacetamide derivatives, Knoevenagel condensation of
2-(3-formyl-1H-indol-1-yl)-N-arylacetamides and 2-cyano-N-(4-methylphenyl) acetamide have been carried out. 2-(3-
Formyl-1H-indol-1-yl)-N-arylacetamides have been easily derived by employing indole-3-carbaldehyde with 2-chloro-Narylacetamides.
All the synthesized compounds have been characterized using analytical techniques such as mass
spectrometry, Fourier transform infrared (FT-IR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. The
biological activity of all the synthesized compounds have been evaluated against a series of bacterial and fungal strains
(Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Rhizopus oryzae, and Aspergillus
parasiticus). Among the synthesized compounds 5e, 5g and 5h demonstrate excellent to moderate antibacterial activity
when compared to standard drugs such as ampicillin and streptomycin. Whereas 5e exhibits antifungal property as compared
to standard drug nystatin.

Authors: Bokhare, Aniket D; Garad, Nitin P; Lokhande, Milind P; Kumbharkhane, Ashok C
Abstract: Complex permittivity spectra (CPS) for dimethylsulphoxide (DMSO) - Water mixtures, in the frequency range of 10 MHz-
30 GHz have been examined, which include the entire concentration range using a time domain reflectometry (TDR) method.
The Cole - Davidson relaxation model has been used to fit the CPS obtained from DMSO - Water mixtures. Mixture’s
relaxation time obtained high at volume fraction of water, Vw = 0.3. The study analyzes the intermolecular interactions using
the Kirkwood correlation factor (KCF) and excess properties. The theoretical dielectric constant for mixtures has been
computed using Alenka Luzar's hydrogen bonding model using different molecular parameters.
