Synthesis, characterization and photocatalytic application of ZnWO4/ZrO2 nanocomposite towards degradation of methyl orange dye

Visible light active ZnWO4/ZrO2 nanocomposite was prepared via hydrothermal method. The nanocomposite was characterized by UV-visible diffuse reflectance spectroscopy (UV-vis-DRS), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Scanning Electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and transmission electron microscopy (TEM) techniques. The XRD results showed that average particle size of ZrO2, ZnWO4 and ZnWO4/ZrO2 were found to be 29.20 nm, 23.78 nm and 20.14 nm respectively and the phase structure for ZrO2 and ZnWO4 in the composite was Rhombohedral and Monoclinic respectively. The UV–vis absorption spectra of the ZnWO4/ZrO2 nanocomposite noticeably shifted to the visible light region compared to that of the ZrO2. The prepared photocatalyst were composed of plate and spongy sphere with little agglomeration was seen from SEM result. The photocatalytic activities of the prepared nanocomposite was evaluated for the degradation of methyl orange (MO) under visible light irradiations. The effect of operational parameters such as initial dye concentration, pH, catalyst concentration and irradiation time have been investigated in detail. The photocatalytic degradation efficiency of ZnWO4/ZrO2, ZnWO4 and ZrO2 for 95%, 72% and 60 % respevtively. The high photocatalytic activity can be attributed to stronger absorption in the visible light region, a greater specific surface area, smaller crystal sizes, more surface OH groups, and to the effect of ZnWO4 doping, which resulted in a lower band gap energy

Green synthesis of silver nanoparticles using <i>Atalantia monophylla</i>: A potential eco-friendly agent for controlling blood-sucking vectors

Abstract Developing floral-based replacement molecules might manage blood-sucking vectors in an eco-friendly way. Atalantia monophylla (Am) aqueous leaf extract (ALE) and silver nanoparticles (AgNPs) were evaluated against mosquitoes (Aedes vittatus, Anopheles subpictus, and Culex vishnui) and ticks (Haemaphysalis bispinosa, Rhipicephalus microplus, and R. sanguineus) at different concentrations. Phytochemical screening and AgNPs' synthesis were performed on ALE of A. monophylla. UV-visible spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscope, and transmission electron microscope were used to examine the synthesized Am-AgNPs. A. monophylla's ALE included alkaloids, flavonoids, saponins, tannins, triterpenes, coumarins, anthraquinones, and phenolics. Am-AgNPs had a higher LC50 (22.19, 23.92, 26.09, 40.25, 51.87, and 60.53 μg·mL−1, respectively) than leaf aqueous extract (LAE) against Ae. vittatus, An. subpictus, Cx. vishnui, H. bispinosa, R. microplus, and R. sanguineus larvae. A. monophylla ALE and Am-AgNPs' bio-toxicity was investigated against aquatic and terrestrial non-target species (Acilius sulcatus, Anisops bouvieri, Araneus mitificus, and Cyrtophora moluccensis) with LC50 values ranging from 2,094.5 to 10,532.8 μg·mL−1, respectively. A. monophylla ALE and Am-AgNPs had little negative impacts on the chosen non-target fauna. Environmental protection is important nowadays. Green AgNPs are low-cost, readily accessible, environmentally safe, and effective pesticides. Am-AgNPs are effective alternative insecticides, requiring a considerable study on this plant to control blood-sucking vectors for worldwide human/animal health importance

2,4-Dichloro-N-phenethyl­benzene­sulfonamide

In the title compound, C14H13Cl2NO2S, the dihedral angle between the phenyl ring and the benzene ring is 69.94 (9)°. Two short intra­molecular C—H⋯O contacts occur and a weak inter­molecular C—H⋯π inter­action is seen in the crystal

The Securing Coding-based Cloud Storage opposed to malignant Attacks

Nowadays cloud is becoming an emerging technology where the user can store their data and access it remotely using the internet. But the security to the user data has becomea major concern. pollution attack, a set of malicious entities trying to corrupt our storeddata in the cloud, which is considered as one of the major risk that affect data security in cloud storage . In our proposed technique , we show how to prevent the pollution attack and how to store our file safely.. The following techniques and algorithm are implementedin our projects.. our first technique is ,the user send the data by encrypting it using RC5ALGORITHM. The user can able to upload the following file format only(.jpg, .txt). The another technique is Checksum Method, a user send an encrypted file to the admin by using this method. This generates a key for that particular encrypted file. The encrypted file has to be verified by the admin. By this verification the checksum method generates a key to the file if the file has same key means the file not hacked or not attached. After verification the admin has to upload the file safely in cloud. If the user need that file means,he has to send a request to the admin.Only after getting the response key from admin the user able to download the file. Our Approach is to very robust and the polluters can be easily isolated

DFT Calculations and In Silico Studies on the Schiff base derivatives with Antibacterial Activities

Abstract &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The heterocyclic Schiff bases (N1Z,N4Z)-N1,N4-bis(3,4-methoxyphenyl)methylidene) benzene-1,4-diamine (1), (N1Z,N4Z)-N1,N4-bis(4-bromobenzylidene)benzene-1,4-diamine (2) and (N1Z,N4Z)-N1,N4-bis(furan-2-ylmethyliden)benzene-1,4-diamine (1) were synthesized by the reported procedure. The molecular structure of the compounds (1‒3) was characterized by FT‒IR and 1H NMR. The bond length, bond angle and HOMO‒LUMO energy gap were calculated out by DFT calculations. The synthesized heterocyclic compounds (1‒3) were screened for their antibacterial activity against Staphylococcus aureus and Escherichia coli. The compound 3 displays superior antibacterial activity compared to standard drug Streptomycin. All the compounds significantly interact with antibacterial protein beta-ketoacyl-acp synthase III and anticancer protein c-Kit tyrosine kinase via p–p, σ–p, hydrogen bonding, electrostatic and van der Waals interactions

ADME-Tox profile of Cuminaldehyde (4-Isopropylbenzaldehyde) from Cuminum cyminum seeds for potential biomedical applications

Cuminum cyminum L (Family: Apiaceae) is a small multipurpose herb. Seeds of cumin are widely used as a spice for its distinctive aroma, and more commonly in various indigenous traditional systems of medicine. Access through web literature provides ample evidence for biomedical activities of Cuminum cyminum seeds (CCS). CCS has been used in traditional medicine to treat variety of diseases, including hypolipidemia, cancer, and diabetes. Biomedical properties of CCS is attributed to its phytochemical class of compounds viz., terpenes, phenols and flavonoids. Health effects of CCS have been experimentally validated through phytochemical screening deciphering the fact that it contains a large number of bioactive secondary metabolites (BASMs) viz., alkaloid, coumarin, anthraquinones, flavonoid, glycoside, protein, resin, saponin, tannin and steroid. Furthermore, pharmacological studies indicate that BASMs in CCS exert antimicrobial, insecticidal, anti-inflammatory, analgesic, antioxidant, anticancer, antidiabetic, anti-platelet-aggregation, hypotensive, bronchodilatory, immunological, contraceptive, anti-amyloidogenic, anti-osteoporotic, aldose reductase, α-glucosidase and tyrosinase inhibitory effects. Cuminaldehyde is one of the major bioactive compounds in CCS that holds significant pharmacological prominence. However, in-depth studies are lacking henceforth warranted to elucidate and fill the gaps, particularly on phytocompound isolation, pre-clinical, clinical characterization, and evaluation of structure–activity relationship. The present study prospects ADMETox perspectives of cuminaldehyde (4-Isopropylbenzaldehyde). Keywords: Cuminaldehyde; Isopropylbenzaldehyde; Cuminum cyminum; ADMETox; Natural Product (NP
