Selective Optical Properties of Cement for Enhanced Radiative Cooling and Energy‐Efficient Construction Materials

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.

A search for starlight reflected from HD 75289 b

open access: yes, 2003
We have used a doppler tomographic analysis to conduct a deep search for the starlight reflected from the planetary companion to HD 75289. In 4 nights on VLT2/UVES in January 2003, we obtained 684 high resolution echelle spectra with a total integration ...

Performance Comparison of Monocrystalline, Polycrystalline, Low Concentrated, and Bifacial PV Modules in a Particular Geographic Location of South India

open access: yesEnergy Science &Engineering, EarlyView.
This study aims to conduct a performance comparison of irradiation and temperature on different commercially available PV modules like PPVM, MPVM, LPVM, and BPVM. Here, the TPVM is not considered in the analysis due to its toxic nature. This study has considered the LPVM because researchers have not focused on it due to the higher area requirement for ...

Estimating the daily mean blue-sky land surface albedo on the Tibetan Plateau using convolutional neural network

open access: yesInternational Journal of Digital Earth
Surface albedo is a critical indicator of Earth’s ability to reflect solar radiation, influencing energy balance and climate dynamics. Research on blue-sky albedo on the Tibetan Plateau has often focused on clear-sky conditions, overlooking seasonal snow

Albedo method applied for gamma radiation shielding

open access: yesBrazilian Journal of Radiation Sciences, 2023
Mathematical tools for calculating radiation shielding usually have difficult notations that could only be solved by computational methods. The Albedo’s method applied for calculation of shielding proves to be an excellent substitute in determining the ...

Functional Bread From Bambara Groundnut and Orange Peel Attenuates Hyperglycemia and Oxidative Stress in a High‐Fat Diet/Streptozotocin‐Induced Type 2 Diabetes Rat Model

open access: yesFood Chemistry International, EarlyView.
This study evaluated Bambara groundnut–wheat composite bread fortified with orange peel in diabetic rats. Diets significantly lowered blood glucose, inhibited α‐glucosidase and α‐amylase, and boosted antioxidant enzymes compared to controls. Results emphasize BG‐based functional foods' potential to help manage type 2 diabetes through regulation of ...

Dual process for improved recovery of essential oil and pectin from citrus waste

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Citrus essential oils (EO), particularly orange essential oil (OEO) and pectin, are high‐value chemical products widely used across various industries, including pharmaceuticals, food and beverages, detergents, and cosmetics. These compounds are present in the residual by‐products generated by juice production industries, and their ...

Diurnal Air–Surface Temperature Dynamics in Hong Kong: An Analysis Across Land Use and Climate Zones

open access: yesInternational Journal of Climatology, EarlyView.
Daytime and nighttime air temperature (Ta) from automatic weather stations and land surface temperature (Ts) derived from ASTER and Landsat 8–9 are used to examine the relationship between Ta and Ts. The spatial and statistical characteristics of Ta − Ts dynamics are further analysed across land use (LU) and local climate zones (LCZ).

Dry‐Season Water Deficits in the Southwestern Amazon Under High Emissions

open access: yesInternational Journal of Climatology, EarlyView.
Projected climatic water deficit in the study region indicates a longer and more intense dry season, with delays in the onset of the wet season under higher emission scenarios. These changes, particularly, pronounced under SSP5‐8.5, suggest increased ecological vulnerability and greater seasonal water stress.
