Rheology Applications in Packaging Materials Abhirup Mitra, Devraj Singh, Anupama Saxena, Vaibhav Verma, Mudita Verma Applied Rheology in Food Processing, 2026 Rheology is a part of fluid mechanics that deals with the flow and deformation of any material and is undoubtedly one of the salient aids for the characterization of fundamental material properties. The Herschel–Bulkley model is considered one of the popular and widely accepted models for fluids, which describes both solid and liquid-like properties for semi-solid materials. Similarly, bulk materials can be analyzed by various geometrical-based testing methods depending on the material attributes. There are two approaches: variegating and combining. Variegating is verifiable and based on industrial experience, whereas combining is mainly based on solid theory and is more associated with polymer science. This chapter is mainly focused on the importance of rheology in packaging by focusing specifically on biopolymers and films. In this chapter, the rheological properties of biopolymer-based packaging materials, including their testing methods, comparative studies, and future perspectives, have also been discussed.
Role of Phytohormones in Abiotic Stress Tolerance Etalesh Goutam, Bharti, Vishal Tripathi, Devraj Singh Phytohormones Important Player in Combating Plant Abiotic Stress, 2025 Climate change presents a significant threat to global agricultural crop production, with abiotic stresses negatively impacting growth and productivity. Phytohormones (PHs) play a critical role in plant stress tolerance by regulating key physiological, biochemical, and molecular processes. PHs such as abscisic acid, jasmonic acid, ethylene, auxins, salicylic acid, and cytokinins, along with novel regulators like brassinosteroids and strigolactones, modulate stress-responsive pathways and processes such as chlorophyll synthesis, ionic balance, leaf morphology, root hair formation, and pH regulation. Additionally, plant growth regulators like sugars, neurotransmitters, and polyamines have emerged as effective strategies to combat both abiotic and biotic stress. PHs not only influence plant growth under optimal conditions but are vital in activating signaling pathways that enhance stress resilience. The interplay between these hormones enhances plant adaptability, making them key for agricultural sustainability in stress-prone regions. Recent advances have shed light on the complex hormonal crosstalk that governs plant responses to stress, highlighting their importance in developing stress-tolerant cultivars. This chapter provides a concentrated knowledge of the most recent advances in our understanding of PHs and their involvement in improving the capability of tolerance to abiotic stress in agriculture and related areas.
Evaluating the impact of nano-zinc and nitrogen fertilizers on growth, yield, nutritional quality and economics of wheat (Triticum aestivum L.) cultivation in Western Uttar Pradesh Krashankant Sharma, Dushyant, Vivek Pandey, Nisha Mahan, Rajesh Kumar, Shekha Singh, Sagar Chaudhary, Rajpal Singh, Mukesh Kumar, K M Rooma, Devraj Singh, Sandeep Kumar Diwakar, Sumit Pathak Plant Science Today, 2025 Wheat (Triticum aestivum L.) is one of the world’s most staple crops, but its productivity is increasingly constrained by widespread deficiencies in soil nutrients, particularly zinc (Zn) and nitrogen (N). This study evaluates the effectiveness of nano-fertilizers (NFs) in addressing these deficiencies under field conditions in Western Uttar Pradesh (WUP), India. Approximately, 50 % of cultivated soil in India, particularly in the Indo-Gangetic Plain, including WUP, suffers from Zn and N deficiencies. The experiment tested the foliar application of Nano-Urea (N-U) and Nano-zinc (N-Zn) and their interactions with various recommended doses of fertilizers (RDF) combinations. The combination of two sprays of N-U and N-Zn with 100 % RDF (T12) resulted in the highest plant height (105.93 cm), number of tillers (317.8 m-2), CGR (22.315 g m-2 day-1) and grain yield (5.59 t ha-1) among all treatments. Moreover, this treatment increased Zn concentrations in grains (34.89 mg kg-1) and straw (9.17 mg kg-1), ensuring higher nutritional quality compared other treatments. Economic analysis showed that T12 provided the highest net returns of ?104579 ha-1 and B:C ratio 3.29, making it the most economically viable option. However, the 100 % RDF (T2) treatment also showed promise as a sustainable alternative, requiring less N input while maintaining productive yields and economic viability. Adopting the superior treatment in Zn- and N-deficient zones could increase yields up to 15 %. The finding demonstrates the synergy between N-U and N-Zn in enhancing nutrient use efficiency, crop productivity and profitability, promoting a sustainable approach for wheat cultivation for nutrient-deficient soils of the Indo-Gangetic Plain.
Bioactive compounds and therapeutic properties of Aloe vera – A review Abhirup Mitra, Manali Singh, Akshita Banga, Jyoti Pandey, Sant Sharan Tripathi, Devraj Singh Plant Science Today, 2023 Aloe vera is a popular herbal medicine and worldwide appreciated for its therapeutic potential. From ancient time, it has been used as a home remedy for different health issues. Many researchers have shown its therapeutic potential and there are many citations of characterization of bioactive compounds from it. A wide range of bioactive compounds have been characterized from Aloe vera. It has a wide range of antimicrobial, antioxidant, and antidiabetic properties. Aloe vera can also provide support for carbohydrate and lipid metabolism by maintaining the level of cholesterol and sugar in blood and it can also help to maintain body weight. Due to the presence of higher number of bioactive compounds and prolific therapeutic properties, it is widely used in medicine, cosmetics and food sector. In this review, the characterisation of bioactive compounds from Aloe vera along with the extraction of its gel and encapsulation is reviewed with a discussion on its medicinal properties.
