“…1D ZnO nanostructures can be formed by different methods, such as chemival vapor deposition (CVD), thermal evaporation, pulsed laser deposition, etc. [4] However, these techniques are costly and complex comparing to hydrothermal growth method. The hydrothermal method has a number of advantages, such as inexpensive simple deposition route at low temperature with high growth rate at environmentally friendly conditions.…”

Molecularly imprinted polymers are important tools for the design of sensors and other molecular recognition based analytical systems. In this paper the development of a photoelectrochemical sensor for selective bisphenol determination is reported. The sensor is based on a glass/ZnO/MIP‐Ppy structure consisting of glass modified by a ZnO layer (glass/ZnO), which is functionalized by molecularly imprinted conducting polymer polypyrrole (MIP‐Ppy). The sensitivity of the sensor to bisphenol is in the range of 0.7–12.5 µm. Selectivity tests to other bisphenolic compounds are performed. Some aspects of a photoinduced response mechanism in glass/ZnO/MIP‐Ppy nanostructures are predicted and discussed.

“…Use of nano structured sensing surface is trending massively for new generation of electrical and photonic devices as described in our previous work with detailed literature review [1]. With significant efforts and available research, it is now possible to fabricate hybrid silicon nano fibrous structure at room temperature with the novel approach of laser ablation as already proven with our previous studies [2,3].…”

With identical extent of energy deposition, alteration in silicon fibrous structure was performed using variation in laserpower and scanning-speed. For validation and further comprehension, SEM analysis and reflective behavior of the surface were studied. Our results show that due to the unique nature of energy deposition by laser ablation process, we could generate relatively denser and defined fibrous structure in considerably shorter period of time at relatively higher laser power and scanning speed. In addition, by controlling the ablation condition, optical behaviors of the generated nanofibrous thin-film (light absorption and reflection) can be customized.

“…One‐dimensional (1D) nanomaterials (nanotubes, nanowires, nanobelts, nanoneedles) have drawn great attention in recent decades. Given their high surface‐to‐volume ratio, 1D nanomaterials have extensive potential to be applied in optical materials, ceramics, electronics, and biomaterials etc . Silicon nitride possesses low thermal expansion coefficient .…”

Needle-like α-Si 3 N 4 with unique structures has potential application in both field emission devices and tips for atomic force microscopes. Single-crystalline, α-Si 3 N 4 nanoneedles have been prepared by using an improved chemical vapor deposition (CVD) method at 1200°C for 3 hours. The phases, chemical composition, and microstructure of the as-prepared products were determined by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) equipped with EDS. The as-synthesized products show a needle-like morphology with hundreds of micrometers in length and nanometer-featured tips. The nanoneedles show a α-Si 3 N 4 @SiOx core-shell heterostructure as characterized by TEM, with single-crystalline α-Si 3 N 4 core and an insulating amorphous silicon oxide shell. The growth of α-Si 3 N 4 nanoneedles corresponds to vapor-liquidsolid cap-growth and base-growth mechanism. Photoluminescence (PL) properties of the products were also characterized. An obvious emission peak at 400 nm under 254 nm UV excitation was observed. The nanoneedle morphology and photoluminescence properties of the products have potentials to be used in future optoelectronic nanodevices.
