A Comparative Study of the Surface Morphology of an Electroless Copper Deposition Bath using a Green and a Non-Green Solvent

Jayalakshmi Suseela, Venkatesh Perumal, Balaramesh Palanivelu,

This article reports the comparative study of surface morphology of the copper deposits using a green and a non-green solvent in an electroless copper deposition bath. The electroless copper plating was studied electrochemically using polyhydroxylic alcohol, Glycerol as the complexing agent and the reducing agents used are, a green solvent, Dimethylamineborane (DMAB) and a non-green solvent formaldehyde (HCHO). The pH of the copper methanesulphonate bath was maintained by using Potassium hydroxide as the pH adjuster. The copper electroless bath was optimized by adding stabilizers at a concentration of 1ppm at 11.50 ± 0.25 pH for DMAB and at 13.0 ± 0.25 pH for HCHO. Alanine(ALA) and Phenyl alanine(PHE) are used as stabilizers.  Their effects on plating bath were studied and reported. The characterization (SEM, AFM, XRD and CV studies) shows that the deposition using DMAB contained bath showed better and eco-friendly results than the formaldehyde used deposition bath.

Laboratory evaluation of the pathogenic effect of fungus Beauveria bassiana (Balsamo) on the
cuticular structure of fourth instar larvae of Anopheles stephensi (L.).

Bharati Veerwal and Arti Prasad,DOI: 10.24214/IJGHC/GC/7/3/64048

The mosquito Anopheles stephensi (L.) (Diptera:Culicidae), is an important vector of malarial parasite in tropical and subtropical areas. Beauveria bassiana (Balsamo) is one of the important biological entomopathogen that seems to be most effective against Anopheles stephensi (L.). In the present study, larvae of Anopheles stephensi infected with Beauveria bassiana were observed for their toxicity and histopahogenecity.Significant mortality with various developmental deformities were observed at LC50 (3.4×6.4×1011 conidia /ml) Histological  studies  further revealed that the entomopathogenic fungus Beauveria bassiana infected and penetrated the cuticle and disintegrated its cells and various layers of cuticle . Since cuticle is  one of the most important structure of insects body, its disruption brought about fragile and deformed body structures causing death of the treated larvae.

Synthetic food preservatives and their impacts on human health

Samir Maji and Soma Gorai,DOI: 10.24214/IJGHC/GC/7/3/62939.

Now-a-days preservatives are added to almost all the packaged food products for preserving the natural characteristics of food as well as for prolonging their shelf life. Preservatives work in different ways; some of them (antimicrobial agents) are used to inhibit the growth of microorganisms, whereas others (antioxidants) can be used to retard the oxidation of food constituents (fats) to reduce rancidity. On the basis of origin, preservatives are classified into natural and synthetic categories, between them a wide variety of synthetic chemical food preservatives are now available in the market and used globally. It plays an important role in food transportation. Although these synthetic chemicals used in the food materials appear to be safe, some of them may be harmful if taken in more than the prescribed limits. Several adverse effects on human health can be found. Hence, the need for developing safe alternatives instead of using these toxic chemicals is becoming essential. This leads the current trends in the food industry to focus on the use of some appropriate and nontoxic natural compounds extracted from different plant parts of various species or from other natural sources like animal or microorganisms. This study provides information about the usages of common preservatives in our food products along with their advantages and disadvantages. We also highlight the current research direction towards the development of safe natural alternatives to increase the consumer’s awareness.

In recent years, green synthesis of metal nanoparticles is an interesting issue of the nanoscience and nanobiotechnology. Nanoparticles produced by plants are more stable, and
the rate of synthesis is faster than that in the case of other organisms. The present investigation was carried out to green synthesis of Iron oxide nanoparticles by using the medicinal plant Ficus Racemosa Leaves. They were synthesized by mixing 9% of 0.01 M aqueous of ferrous sulphate with 1% aqueous extract of Ficus Racemosa Leaves. The formation of nanoparticles was monitored by visualizing colour changes and it was confirmed by Electron microscope (SEM), UV-Vis spectrophotometer and Fourier Transform Infra-Red (FT-IR) spectroscopy.This work proved the capability of using biomaterial towards the synthesis of Iron Oxide nanoparticles, by adopting the principles of green chemistry.

maculatusis a pest of pulses like cowpea, green gram, and black gram. The pest infests in both field and storage conditions. In the present experiment neem seed kernel extract used to protect stored grains from pest population. For NSKE the mean percentage of reproduction control is 27.13. Insect pests have been a threat to food products. Neem products play a significant role in controlling them
