The present paper introduces a novel approach to modern waste management by integrating technology with waste disposal systems. In response to the need for more engaging and efficient waste disposal methods, we propose an interactive smart dustbin. This dustbin, enhanced with robotic features and advanced sensors, aims to revolutionize how individuals perceive and participate in waste management practices. The design, implementation, and potential applications of the interactive smart dustbin are presented herein, with a focus on its potential to promote responsible waste disposal habits across diverse settings. Additionally, the integration of solar power as an alternative energy source is explored to enhance the system's sustainability.

The emergence of environmental challenges begins with applications of the different development models as both have vis-à-vis relationships. Sustainable development is a modern concept in which the complementary aspect of two opposites is considered as a key factor and provides a route to gradual development which favours to environment of the planet Earth and matches with the Gandhian thought of development. Gandhian thoughts are deep-rooted in the rich Indian tradition of world welfare. This paper finds the application of Gandhian thoughts to mobilize the generation for acceptance of development models suitable for planet Earth in terms of environmental concerns and the long existence of natural ecology.

In the present era of technically feasible and environmentally compatible low-cost material substitution with the basic ingredients of conventional concrete mix, the infusion of eggshell powder in its raw as well as incinerated forms was tried with the cement mantle. Experimentations carried out to endorse the compressive strength, split tensile strength, flexural strength, workability and durability aspects revealed that it had the edge over the properties standardized for the conventional concrete mix at a specific mix strength of 20 MPa. The experimental results for variations in the treatments of eggshell powder and incinerated eggshell powder corresponding to the responses on the evaluation parameters were compared with the conventional concrete mix by means of regression analysis and modelling. The regression model at more than 95% correlation level of the experimental data fortified the relative supremacy of eggshell powder and incinerated eggshell powder-infused concrete mixes over the conventional concrete mix in terms of workability, strength, and durability. Based on the statistical regression point of inflexion and the point of tolerance, it was clearly established that 20% optimal proportional addition of eggshell powder or 30% addition of incinerated eggshell powder could result in a superlative performance compared to the conventional concrete mix. This final outcome of the optimal combinations of eggshell powder and incinerated eggshell powder incorporated concrete (EPIC) was also test verified by SEM and EDAX analyses.

In this work, a biosensor under Kretschmann configuration with enhanced sensitivity utilizing thiol on the bimetallic layers of magnetic material nickel (Ni) over silver (Ag) is proposed and analyzed numerically using the Fresnel equation and the Transfer Matrix Method (TMM). Results have shown that such a hybrid configuration with a well-optimized thickness of a bimetallic layer of Ni over Ag and the proper utilization of thiol with fixed thickness can increase the sensitivity substantially higher than the conventional sensor. The minimum reflectivity, FWHM of the Surface Plasmon Resonance (SPR) curve and sensitivity were examined in order to optimize the thickness of metal layers for the fixed thickness of the thiol. It is observed that sensitivity as high as 321º/RIU is obtained for the configuration consisting of 15 nm of Ni over 40 nm thickness of Ag added with a 4 nm thickness of thiol. Such high-sensitivity sensors can be used for protein-protein interaction and virus detection in the field of biosensing applications.

The infections/diseases are caused by many antibiotic-resistant bacteria, virus, fungi and protozoan parasites. The discovery of the plant origin of antibiotic drugs has inevitably fostered the development of resistance in microorganisms. The variety of natural candidates of plant origin, many leaves and fruits have potent antibacterial activity. This study is aimed at determining the antibacterial activity of pineapple (Ananas comosus) fruit bar extracts used for the antibacterial activity was carried out by agar well-diffusion technique and the activity was measured by the zone of inhibition in diameter. The results of the study revealed that the various extracts of pineapple (P1, PS2 and PJ3) have potential activity against both gram-positive bacteria (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli).

Water tainted with colours, heavy metal ions and biological toxins, contributes to eutrophication, which in turn contributes to a variety of fatal diseases in humans and other animals, owing to the fact that water purification equipment and methods are not cheap. Due to this, there is a pressing need for economically viable wastewater treatment components. Eco-friendly nanomaterials, highly efficient and selective, renewable, earth-abundant and stable, have emerged as a major priority, overcoming a number of challenges and restrictions. Currently, the combination of nanomaterials and biomolecules from plants, including polyphenols, amines and other components, as well as intracellular and extracellular enzymes found in microbes, has become more significant in bioremediation. Biogenic nanoparticles are favoured because they are easy to expand for large-scale biosynthesis, maintain stability for an extended period, consume less time, are eco-friendly, and do not produce any detrimental by-products. The processes of nano-bioremediation and wastewater treatment are discussed in detail in this review. It primarily focuses on synthesizing, characterizing and applying bio-mediated nanoparticles, which actively remove heavy metal ions from wastewater, without adversely affecting individuals or other living things, especially in aquatic environments.

Nowadays, the demand for high-voltage pulse generators has begun to proliferate in many industries. Particularly in the food processing industries, the conventional method of pasteurization involves the use of heat treatment processes, which are not environment-friendly; hence, researchers are working towards environment-friendly, non-thermal food processing techniques by which the microorganisms present in the liquid food can be eliminated. High-voltage pulsed electric field technology is one of the popular non-thermal food processing techniques. Recent advancements in power electronic switching technology have facilitated the development of solid-state pulse generators for these applications. In this paper, the simulation of a high-voltage pulse generator for eco-friendly pasteurization applications has been attempted using a cascaded boost converter topology. The entire simulation is carried out using MATLAB/Simulink software. The designed two-stage cascaded boost converter is tested for varying duty cycles and loads. The results with resistive and inductive loads have been analyzed.

Malaria diagnosis using sophisticated methods is highly expensive and time-consuming. The development of sensitive, selective, robust, accurate, fast and low-cost clinical diagnosis techniques has been a major focus of researchers in recent years. In this work, nickel nanoparticles have been synthesized successfully using Calotropis gigantea leaf extract, by Co-precipitation method and then characterized by Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), Energy Dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FT-IR) and Ultraviolet-visible (UV-Vis.) spectroscopic techniques. FT-IR spectra showed a sharp peak at 699 cm -1 and a broad peak ranging from 2500 - 3500 cm-1 ensuring the construction of nickel nanoparticles. X-ray Diffraction pattern revealed a face-centered cubic structure. The SEM image has shown the spherical structure with a rough area. The results obtained were satisfactory in terms of antimalarial applications of the nickel nanoparticles.
