In the present study, we have investigated the utilization of the SPS technique for the development of nanocomposites rei...

Lignin is an amorphous natural polymer with multifunctional phenolic network accounting for approximately 15-30% of lignocellulosic biomass. Different functional groups like carboxyl, hydroxyl, phenolic and methoxy in lignin molecules may act as suitable interaction sites for the removal of pollutants. Lignin, as an abundant and renewable bioresource, can be used to create nanofibrous membranes via electrospinning technique. Such membranes with elevated specific surface area, uniform fiber di...

This research paper discusses a bidirectional DCDC fast charger (or level-3 charging system) to obtain a highpower level. However, two types of EV charging systems are available, i.e., an on-board charging system and an off-board charging system. For dc fast charging, it is essential to use the off-board charger to reduce the volume and weight of EVs significantly. This charger charges the EV battery using a Dual Active Bridge (DAB) topology for the DC-DC converter, which is better for bidire...

Energy Harvesting from diverse renewable energy sources has experienced rapid growth due to the adverse environmental impacts of using fossil fuels. Solar energy is a signi cant energy source frequently used for power generation in various applications. Due to the variable nature of solar irradiation, temperature, and other metrological parameters, Photovoltaic (PV) power generation is highly uctuating. This unstable nature of output power has been evolved as a considerable issue in various ...

Superheated steam is gaining wide attention as a novel processing technology in the food sector. It can be generated at atmospheric pressure, under vacuum or at above atmospheric pressure. At atmospheric superheated steam is generated above the boiling point of water at atmospheric pressure by adding additional heat to saturated steam. Moreover it will not condense till the temperature is maintained above the saturation temperature of steam at atmospheric conditions. Apart from drying variou...

Yardlong bean (Vigna unguiculata ssp. sesquipedalis) belongs to the cowpea species. They are widely available in South Asian countries and known for their high protein and vitamin content. They degrade fast after harvest due to its high enzyme activity. Peroxidase enzyme is the most active enzyme present in yardlong beans. In this study near-infrared radiation was used for blanching. 90% inactivation of peroxidase occured when yardlong beans was treated for 4 min by infrared in the presence o...

Bioactive compounds including Resveratrol (RES) have been proven to have anticancer, antioxidant, anti-inflammatory, and cardio protective effects. However, the low bioavailability, poor water solubility, and sensitivity to UV light and heat render RES unsuitable for use in food applications. These problems can be alleviated by encapsulating RES. Internal gelation is a promising encapsulation technique that has the potential to protect RES from adverse environmental conditions. The aim o...

The process of automatically detecting abnormal video patterns in the intelligent surveillance framework is known as video anomaly detection. However, video anomaly detection is challenging due to inherent research challenges such as equivocal nature, data imbalances, data scarcity, the complex nature of the entities involved in the anomaly, etc. Hence, a self-attention-enabled convolutional spatiotemporal autoencoder is proposed to detect video anomalies efficiently. The proposed Self-Attent...

Rice production is vulnerable to a number of pressures; one of the main biotic stresses is blast disease, which is brought on by Magnaporthe oryzae and has the potential to wipe out the entire crop under extreme circumstances. Microbial-mediated seed and root prime in plants enhance defense against a broad range of pathogens by jasmonate (JA) and ethylene (ET) signaling mediated induced systemic resistance (ISR). The present work demonstrates some selected microbes like Bacillus cereus, Pseud...

Rice is grown extensively in many parts of the world at different times of the year under different climatic conditions. Rice is the most essential cereal crop that forms a major part of the human diet and is hence popularly called "Global grain". With the increasing trend of the rising human population, it’s high time to have crops with high yield potential and stability. Making the rice-based production system sustainable is crucial for the future food security of mankind. Rice blast is one...

Due to the advancement of photo editing techniques, it has become easier to create fake photos that look incredibly realistic and are edited in a way that leaves no visible signs of manipulation, making them ideal for synthesis. However, Instagram, WeChat, and TikTok are some of the popular social media platforms where the images have been lossy compressed before uploading them. As a result, learning to spot forged images in their compressed form is crucial. As part of this, some forensic det...
