“…The Raman spectra of SiO 2 and the final product are shown in Figure b. The mode at 487 cm –1 in the SiO 2 spectrum can be beneficial to the bending vibration of the Si–O bond, which is the characteristic bond of amorphous silica . The mode was maintained inconspicuous in the spectrum of the SiO 2 /MXene/HPTFE sample.…”

Water treatment through interface photothermal conversion using solar energy is a sustainable strategy for freshwater supply. Because the preparation method of highly efficient photothermal conversion materials with commercial value is the only way for the industrialization of solar steam generation, the preparation method and the rational design of photothermal materials are particularly important. In this work, the highefficiency photothermal conversion material MXene nanosheets and low thermal conductivity SiO 2 were coated on a hydrophilic poly(tetrafluoroethylene) (HPTFE) membrane by a commercial continuous spraying system to produce a SiO 2 /MXene/HPTFE Janus membrane. They possess excellent mechanical properties, high stability, and 93.0% light absorption. The prepared evaporator can be used for water treatment with a photothermal evaporation rate of 1.53 kg m −2 h −1 , achieving a uniform and effective 85.6% solar thermal conversion efficiency, which is superior to most reported work. The removal rate of wastewater and organic pollutants can reach 99.9%. At the same time, the two-dimensional Janus membrane has excellent salt resistance and self-cleaning ability, making it easy to store and transport. It is also used to build sensor systems. The sensor has an excellent light response and can accurately measure solar radiation density and temperature in a short time. Therefore, the use of commercial spraying systems provides a cost-effective and energy-saving strategy for photothermal evaporators and sensors to reduce the use of photothermal materials, achieve higher photothermal evaporation rates, and expand the application direction of photothermal materials.

Influence of Deposition Time on Titanium Nitride (TiN) Thin Film Coating Synthesis Using Chemical Vapour Deposition

et al. 2023

Titanium nitride (TiN) thin film coatings were grown over silicon (p-type) substrate using the atmospheric pressure chemical vapour deposition (APCVD) technique. The synthesis process was carried out to evaluate the effect of deposition time on the physical and mechanical characteristics of TiN coating. Thin films grown over Si substrate were further characterised to evaluate the morphological properties, surface roughness and mechanical properties using a scanning electrode microscope (SEM), atomic force microscopy (AFM) and nanoindentation, respectively. EDS equipped with SEM showed the presence of Ti and N elements in considerable amounts. TiN morphology obtained from the SEM test showed small-sized particles on the surface along with cracks and pores. AFM results revealed that by increasing the deposition time, the surface roughness of the coating also increased. The nanomechanical properties such as nanohardness (H) and Young’s modulus (E), etc., evaluated using the nanoindentation technique showed that higher deposition time led to an increase in H and E. Overall, it was observed that deposition time plays a vital role in the TiN coating deposition using the CVD technique.
