Nano thin films and nano coating have been applied in different fields in health care system because of their higher antiviral properties. Additionally, as the world have suffered since December 2019 from Covid-19 situation, different scientists and industrials people have tried to apply nano antiviral films and coatings in our daily life. In this short review, nano thin film coating procedure by DC sputtering technique has been reviewed, investigated, and evaluated by using different materials and device parameters in recent years. This report focuses on device factors that affect the thickness of nano-thin films for optical and optic-electric applications. These parameters including time, temperature, power, pressure, and flow rate of gases. The review provides more understanding meaning of the coating procedure by DC sputtering process.

AbstractPolymer thin films offer a versatile and ubiquitous platform for a wide variety of real-world applications in biomedicine, nanotechnology, catalysis, photovoltaic devices, and energy conversion and storage. Depending on the chemical composition of the polymers and the associated microenvironment, the physicochemical properties (biocompatibility, stability, wettability, adhesion, morphology, surface free energy, and others) of polymer films can be tuned for a specific application through precisely controlled surface synthesis and the incorporation of desirable and responsive functional groups. In this short review, we first summarise the methods most commonly used for the fabrication of polymer thin films. Then we discuss how these polymer thin films can be used in a selection of biomedical applications in antifouling materials and biosensors. Some directions for the rational design of polymer thin films to achieve a specific function or application are also provided.

We present some experimental results on the temperature dependence of the surface resistance Rs and magnetic penetration depth λ of thin films of SmBa 2 Cu 3 O 7-δ. The samples, 0.25 μm thick, were grown by a dc sputtering technique on (100) K LaAlO 3 single crystal substrates, with critical temperatures ranging between 87 and 88 K Accurate measurements af the surface impedance Zs were performed down to 4 K by means of a dielectrically loaded cavity operating in the microwave region (20 GHz). Both λ and Rs show a monotonic temperature behavior, with no evidence of low temperature up-turn characteristic of other rare earth based cuprates like GdBa 2 Cu 3 O 7-δ. At low temperatures, we observed am almost linear behavior of λ with a slope of ~ 0.3 nm/K up to 25 K, as expected in a d-wave pairing scenario. The real part of complex conductivity σ1, shows a bump at around 40 K, in agreement with previous reports.

A sol-gel method combined with spin-coating process has been developed for deposition of nanostructured thin films of La0.85Sr0.15MnO3(LSM) on La0.6Sr0.4Co0.2Fe0.8O3-δ(LSCF) pellets. The quality of the LSM films depends sensitively on the solution chemistry and other processing parameters. It was found that the optimal molar ratio of citric acid to ethylene glycol and to metal ions is 4:16:1 for the LSM sol. An amount of ethylene glycol was added into initial LSM sol to adjust the viscosity and the best value tested was 1.62×10-2Pas. A more uniform LSM film can be obtained with a suitable heating rate during firing. Modification of LSCF with a thin film coating of LSM has potential to enhance both stability and electrocatalytic activity for oxygen reduction.
