“…Mineral paper is an innovative and emerging material that offers greater environmental benefits than conventional paper. It does not require trees for production, reduces water usage, eliminates the need for bleaching, and is easily recycled to produce new mineral papers or to be utilized in other applications, contributing to waste reduction and resource conservation 17 . The use of abundant and cost‐effective resources like limestone and marble significantly reduces reliance on timber and helps mitigate forest depletion.…”

Mineral paper, a synthetic paper‐like material primarily composed of ground calcium carbonate (CaCO3) and a small amount of high‐density polyethylene (HDPE), has emerged as an important alternative to traditional paper and board due to the increasing demand for pulp and paper and the shortage of trees and fibrous material in many regions worldwide. This study aimed to investigate the impact of accelerated weathering and aerobic biodegradation on three different types of mineral papers. The specimens underwent 1000 h of accelerated weathering using a Gardner weathering device and were also buried in soil at a depth of 5 cm for 3 months with regular watering conditions for biodegradability testing. Physico‐chemical characterizations such as optical (whiteness), surface (roughness, contact angle, and paper topography), and chemical properties of the samples were studied before and after the artificial weathering and biodegradation tests. The results revealed a visible color change (darkening) in mineral papers, with an increase in HDPE content leading to a darker color after weathering and biological degradation. However, there were no significant differences in the color change between weathering and soil‐burial tests. The biodegradability test resulted in a decrease in ash content due to the demineralization process. All samples' surface roughness was reduced after weathering and biodegradation tests. The FT‐IR and EDS analyses confirmed the presence of calcium, carbon, and oxygen elements in all three samples, indicating a large amount of calcium carbonate in the mineral papers. The scanning electron microscopy (SEM) images showed the creation of micro holes and cracks on the surface of the samples after weathering and biodegradation. Overall, the soil‐burial test showed more degradation than the weathering test.Highlights The influence of weathering and biodegradation of mineral papers were studied After soil‐burial test, the ash content decreased due to the demineralization After weathering, micro cracks were created on the surface of the samples The degradation of the soil‐burial test was more than the weathering test Mineral papers most likely contain carbonate calcium and HDPE

“…[3][4][5] Many phosphate-based inorganic metal compounds have been synthesized by researchers and utilized in diversified fields, ranging from energy storage to catalysis. [6][7][8][9] In recent times, the usage of heat repellent material 10 is as significant as heat storage materials. Swain and Brahma 11 have studied nickel mixtures for possible use as heat repellant material.…”

Four different mixtures such as complex mixture A, [Co(H 2 O) 4 (HPO 4 )] (C 3 H 4 N 2 )(H 2 O) 2 Á 0.2 (C 3 H 4 N 2 ), complex mixture B, [Co(H 2 O) 6 ](H 2 PO 4 )(OH) (H 2 O) Á(C 3 H 4 N 2 ) 2 , mixture C, 0.34 Co(PO 3 ) 2 Á0.15(C 3 H 3 N 2 Na), and complex mixture D, 0.03Co(PO 3 ) 2 Á0.25(C 3 H 3 N 2 Na) Á0.1 [Co(H 2 O) 6 ]SO 4 .H 2 OÁ0.6 (C 3 H 4 N 2 ), were synthesized using ortho-phosphoric acid and meta-phosphoric acid with cobalt sulfate heptahydrate and imidazole in ambient conditions. These mixtures have been well characterized by different thermo-analytical techniques. Differential Scanning Calorimetry (DSC) has been carried out at different heating rates such as 5, 10, 20, and 30 K min −1 at atmospheric conditions. The specific heat capacity was measured at low temperatures up to 173 K for mixture C at a rate of 10 K min −1 . From the thermal analysis, it can be observed that the complex mixtures A and B prepared using phosphoric acid and mixture C prepared using meta-phosphoric acid behave as heat repellent material owing to their exothermic behavior at high temperature. The anomalous negative specific heat capacity exhibited by the mixtures is explained using partial molar quantities. Among all the four complex mixtures, the complex mixture A has been found to be the best heat repellent material.The complex mixture B can be used as heat storage material up to temperature $550 K due to its endothermic behavior. These phosphate materials can be used for longer period of time due to their stability and insolubility in aqueous media. The heat can be extracted from any system that is coated with these phosphate mixtures using high conductivity copper rod.

Because of this, the modern technological man is striving hard to explore all possible options to cater to the ever-increasing demand for energy. Conventional energy reserves, viz. coal and fossil fuels, have already been exploited to their maximum extent and their collateral impacts of environmental pollution and global warming leading to climate change. It is indeed essential to scout around various viable sources of renewable energy, such as extracting
