A sensible thermal energy storage (TES) system is studied using Hytherm 600 oil as the storage medium and a 30:70 ethylene glycol–water (EG-W) mixture as the discharging fluid, owing to its extended operating temperature range (− 14 ◦C to 105 ◦C) at atmospheric pressure. The EG-W mixture alleviates the working limitations of pure water by lowering the freezing point and elevating the boiling point, making it suitable for solar thermal systems in colder climates and for low-temperature industrial heat recovery without pressurized systems.

Dalbergia latifolia Roxb. (Indian rosewood) is a high ecological and economic value, native to India’s tropical and subtropical forests. This study presents the first high-resolution, range-wide habitat suitability assessment of across India using MaxEnt modelling. By integrating over 3,200 geo-referenced occurrence records with 19 bioclimatic variables, the research identifies key ecological zones and conservation gaps for this ecologically vital and economically valuable species.

This study discusses notions of plant consciousness within the classical Ayurveda text, the Caraka Saṁhitā (CS) and its ideas on vegetal ‘being’. Drawing extensively from Cakrapāṇidatta’s commentarial gloss on the CS, the Āyurvedadīpikā, it begins by pointing to two frequently conflicting conceptualizations and positions ascribed to plants within the text: (a) plants as material agents of therapy and (b) plants as sentient and conscious ‘beings’.

High energy density and minimal energy losses render thermochemical energy storage (TCES) systems a promising long-term solution for space heating applications. While inorganic salt hydrates are considered effective thermochemical materials, challenges such as cycling stability, agglomeration, and deliquescence during the charging and discharging processes limit their efficacy. Porous matrices, like silica gel (SiO2), present a viable alternative to address these issues.

The present study uses a three-dimensional numerical model to investigate the thermal stratification performance of vertical cylindrical thermal energy storage under simultaneous charging and discharging operations pertinent to low-temperature (below 100 ℃) industrial applications. First, the study investigates an oil-based TES using Hytherm 600 as the heat storage medium, and water circulating through the
