TiO/InO nanowire (NW) array are prepared using catalyst free glancing angle deposition technique. The wettability of TiO/InO NW surface are tuned and controlled by the annealing treatment without altering the surface with additional chemical coating. The phase change, surface roughness, change in static and dynamic contact angles due to the heat treatment are studied. Moreover, the surface properties such as frictional force and work of adhesion are calculated for all the samples. The samples annealed at 600 °C shows nearly superhydrophilic with static water contact angle of 12°, frictional force of 85.00748 µN and work of adhesion of 142.3721 mN/m. The surface of TiO/InO NW is controlled to attain desired water contact angles and sliding angles, which is paramount for designing practical application in self-cleaning, electronic and biomedical fields.

Photocatalysts composed of ZnSe nanorods were prepared by using a glancing angle deposition technique facilitated by electron beam evaporation equipment. To enhance the photocatalytic efficiency of ZnSe, a vulcanization process was introduced. The impact of various parameters, including curing temperature, duration, and nanorod length, on the photocatalytic performance was systematically examined.

Enantioselective discrimination is critical in several fields, particularly in pharmaceutics and clinical drug research. Chiral molecules possess unique charge transfer properties, showing an enantioselective preference for electron spin orientation when interacting with the magnetic surface. Here, we developed spin-selective charge transfer (SSCT)-based label-free surface-enhanced Raman scattering (SERS) achiral magnetic substrates for the enantioselective discrimination of chiral molecules without creating asymmetric chiral adsorption sites.

Flexible thermoelectric materials are usually fabricated by incorporating conducting or organic polymers; however, it remains a formidable task to achieve high thermoelectric properties comparable to those of their inorganic counterparts. Here, we present a high zT value of 1.29 ± 0.

The requisite phase-conjugate mirror inside the resonator is constructed using non-degenerate four-wave mixing (4WM) in rubidium vapor. The glancing-angle phase-conjugate mirror is a 100% output coupler, and therefore this resonator is unusual in that no light circulates the cavity more than once.

Micromotors are the backbone of material research as they are small-sized, self-propelled, intelligent systems capable of performing multiple tasks ranging from biomedicine to environmental monitoring. One of the primary obstacles the field faces is the live detection and differentiation of individual units through a complex environment. In this study, we demonstrate a facile approach for designing light-activated dye-tagged micromotors on a large scale.
