Fabrication and Characterization of MWCNTs Decorated ZnO Nanograins Based Sensor for Enhanced Performance Toward CO2 Gas

open access: yesAdvanced Materials Interfaces, EarlyView.
The present work is concerned with the fabrication of CO2 sensors based on MWCNTs/ZnO material, which is obtained by RF magnetron sputtering and electron‐beam deposition methods. The sensor exhibits highly sensitive and selective behavior, high repeatability, and temporal stability at low CO2 concentrations.

Locking in Color: Stable RGB Perovskite Nanocrystal Films via UV Cross‐Linking

open access: yesAdvanced Optical Materials, EarlyView.
Combining block copolymer stabilized lead halide nanocrystals with a UV light‐based cross‐linking procedure yields ultra‐stable nanocrystal thin films, which are resistant to dissolution by organic solvents and impervious to interlayer ion exchange. This allows for the fabrication of stacked layer RGB all‐perovskite white light‐emitting phosphors with ...

Greenhouse gas mitigation and electricity saving potential from replacing refrigerants in Thai refrigerator

open access: yesEnergy Reports, 2021
Refrigerant leak from refrigerator production and operation is one of major sources that causes greenhouse gases (GHG) emission due to the high global warming potential (GWP) from existing Tetrafluoroethane (R-134a) which is hydrofluorocarbon (HFC ...

The Global Warming Potential of Geoengineering via Radiative Cooling

open access: yesAdvanced Sustainable Systems, EarlyView.
The cooling power of engineered radiative cooling materials is determined and compared to conventional construction and roofing materials and Earth's natural surfaces. Results show if 1% of Earth's surface are to be covered with state‐of‐the‐art radiative cooling materials the terrestrial radiative forcing would decrease by 1.61 W·m−2 (from 0.6 to −1 ...
