Subcritical-Water Extraction of Natural Products
Subcritical water refers to high-temperature and high-pressure water, but below water's critical point of 374 °C and 218 atm. A unique and useful characteristic of subcritical water is that its polarity can be dramatically decreased with increasing temperature. Therefore, subcritical water can behave similarly to methanol or ethanol. This makes subcritical water a green extraction fluid used for a variety of organic species.

Strategic Alliance for Resilience in Supply Chain
Resilience is a particularly important quality for supply chains in this turbulent environment. Resilience in the supply chain is the ability to retain, resume, and recover operations after an intense destructive incident. One of the strategic solutions for managing supply chain disruptions is to establish collaboration and strategic alliances in order to achieve competitive advantage.

Stabilization of Rice Bran
One of the major problems in food science is meeting the demand of the world’s growing population, despite environmental limitations such as climate change, water scarcity, land degradation, marine pollution, and desertification. Preventing food from going to waste and utilizing nutritive by-products as food rather than feed are easy and powerful strategies for overcoming this problem. Rice is an important staple food crop for more than half of the world’s population and substantial quantities of rice bran emerge as the main by-product of rice grain milling. Usually, rice bran is used as animal feed or discarded as waste. Although it is highly nutritious and comprises many bioactive compounds with considerable health benefits, the rapid deterioration of bran limits the exploitation of the full potential of rice bran. Hydrolytic rancidity is the main obstacle to using rice bran as food, and the enzyme inactivation process, which is termed stabilization, is the only way to prevent it.

Solar-Powered Plant Protection Equipment
Solar photovoltaic (PV) devices present a positive approach to sustainable crop production by reducing crop loss in various ways. This might result in the extensive use of PV devices in the near future. PV-based plant protection equipment/devices are primarily utilized in protecting crops from birds, weeds, or insects. The utilization of PV systems for different applications constitutes a new era in agriculture, horticulture, and forest sectors. A PV system is a potential alternative, offering more opportunities in operating different types of electricity-based agricultural equipment. The development of devices with simple construction/operation for plant protection may work well on small-scale farms.

Solar Energy Potential and Solar Irrigation in Pakistan
Pakistan faces water scarcity and high operational costs for traditional irrigation systems, hindering agricultural productivity. Solar-powered irrigation systems (SPIS) can potentially provide a sustainable and affordable solution, but face technical, financial and policy barriers to adoption.

Soil-Borne Diseases of Flax (Linum usitatissimum)
Flax is an important crop cultivated for its seeds and fibers. It is widely grown in temperate regions, with an increase in cultivation areas for seed production (linseed) in the past 50 years and for fiber production (fiber flax) in the last decade. Among fiber-producing crops, fiber flax is the most valuable species. Linseed is the highest omega-3 oleaginous crop, and its consumption provides several benefits for animal and human health. Among biotic factors, soil-borne eukaryotic diseases pose a significant threat to both seed production and fiber quality, which highlights the economic importance of controlling these diseases.

Soil Disturbance in Arable Soil Tillage
Arable soil tillage is the largest soil perturbation activity on Earth, and, astonishingly, the direct and indirect benefits of such global soil disturbances have a limited framework for its estimation. Seasonal soil tool interactions disrupt the pristine bio-physio-mechanical characteristics of agricultural soils and crop-oriented ecological functions. They interfere with the natural balancing of nutrient cycles, soil carbon, and diverse organic matter that supports soil ecosystem interactions with crop rooting. Researchers reviewed soil working in tillage, associated mechanistic perturbations, and the edaphic response of affected soil properties towards cropping characteristics and behavior as soil working tools evolve. This is to further credit or discredit the global transition to minimum and no-till systems with a more specific characterization to soil properties and edaphic crop-oriented goals of soil tooling

Smart Farming and Internet of Things Platform
Nepal, a lower-middle-income country in South Asia, predominantly features smallholder farming communities operating on modest land holdings. These smallholders often adhere to traditional farming methods, relying on familial labor, which has become increasingly inefficient in contemporary agricultural landscapes. To enhance their productivity and efficiency, smallholder farmers require affordable and accessible Internet of Things (IoT)-based systems.

Silicon Waveguide Grating Modulators
Silicon waveguide grating modulators are such silicon modulators with waveguide gratings introduced to the modulation regions. As a kind of period optical structure, the waveguide gratings in the modulator will generate slow light effect to increase the light-matter interaction. Through this approach, the modulation efficiency can be enhanced and a more compact modulator footprint can be obtained. Simultaneously, silicon waveguide grating modulators can be fabricated under CMOS process which have lower process requirements than silicon photonic crystal modulators. While maintaining high-speed performance and CMOS compatibility, silicon waveguide grating modulators have ultra-compact footprint compared with conventional silicon Mach-Zehnder modulators, which will play an important role in future high-density optoelectronic integration.

Shear Energy on Harvesting Tools
Smart and precise agriculture has increasingly been developed in the last decade, and with that, the idea of optimizing the tools commonly used in this field for harvesting tasks. One way to improve these devices, particularly cutting tools conceived for harvesting purposes, is to measure the shear energy consumption required for a particular plant. The proposed methodology aims to establish both a design criterion for cutting grippers and a quantifiable way to evaluate and classify a harvesting tool for a specific crop.
