“…Temperature, moisture, and airflow are just as important as the pH solution and removed velocity. They all have an impact on the film's parameters [9,18,19]. Evaporation of solvents (primarily ethanol and water) forms thin films, which concentrate non-volatile species in the system and cause aggregation and gelation.…”

Metallic biomaterials such as 316L stainless steel (SS316L) are widely used as an implant to replace the function of damaged bone, especially in hip or knee applications. However, many of them fail during a short period or have complications. The biocompatibility issues are the main factor that caused this failure. Thus, coating the SS316L with bioactive and biocompatible material is one of the promising techniques to enhance the biocompatibility and lifetime of the implant. This paper provides an overview of the SS316L foam coated hydroxyapatite (HA). Various methods of HA coating such as sol-gel, dip coating, electrophoretic deposition, plasma spraying, and pulse laser deposition applied on SS316L foam and their coating characteristics were investigated based on recent literature. SS316L foam coated HA using different coating methods were compiled and their basic properties were reported. Therefore, this paper will benefit future works on SS316L foam coated HA in a biomedical application.

Bu çalışma kapsamında öncelikle katkısız TiO2 filmler daldırarak kaplama yöntemi ile üretildi. Optimum katkılı ve katkısız ince film biriktirme parametreleri yapılan ön denemeler ve daha önceki çalışmalar derlenerek; daldırma tekrar sayısı 8 kat, daldırma süresi 90sn, süreç arası kuruma sıcaklığı 110 °C, süresi 150 sn, tavlama sıcaklığı 500 °C ve süresi 2 saat olarak belirlendi. Daha sonra farklı fiziksel özelliklere sahip Al ve Cu metalleri ile katkılanarak, katkılamanın TiO2 ince filmlerin yüzeysel, yapısal ve optik özellikler üzerine etkileri incelendi. Katkılama oranları değiştirilerek (%1, %3, %5) katkılama ile TiO2 ince filmlerin fiziksel özelliklerindeki değişimler belirlendi. SEM görüntülüleri incelendiğinde; cam altlıklar yüzeylerine TiO2 ince filmler homojen olarak biriktirildiği ve Al katkılamanın TiO2 film katmanlarındaki tanecik boyutunu küçülttüğü, Cu katkılamanın ise tanecik boyutunu büyüttüğü tespit edildi. XRD analiz spektrumu verileri ile hesaplamalar sonucunda tanecik boyutundaki değişimlerin SEM görüntülerine uyumlu olduğu görüldü. Katkısız TiO2 ince filmler için Anataz fazında TiO2'nin bilinen net tepe noktaları, Al ve Cu katkısından kaynaklanan pikler XRD spektrumunda tespit edilerek ince film biriktirme işlemlerinin başarıyla yapıldığı belirlendi. Optik özellikler incelendiğinde yasak enerji aralığı TiO2 ince film için 3,21eV olarak hesaplandı. Al katkılama ile TiO2 ince filmlerin yasak enerji aralığının arttığı ve Cu katkılama ile yasak enerji aralığının azaldığı tespit edildi.

Titanium dioxide layers are the most popular electron transport layer (ETL) in perovskite solar cells. However most studies focuses on mesoporous structure and application with organic–inorganic hybrid perovskite. In this study, the topic of ETL in planar structure of inorganic CsPbBr3 perovskite solar cells was tackled, the presented approach will reduce production costs and improve cell stability, which is the greatest drawback of perovskite cells especially organic–inorganic perovskite. The potential application of these technology are greenhouses and building integrated PV sector. Here, the two TiO2 precursors titanium(IV) ethoxide in ethanol and titanium(IV) bis(acetylacetonate) diisopropoxide (Tiacac) were investigated, optimized and compared. TiO2 layers were deposited on high roughness FTO, without the use of a mesoporous layer, by spin coating method. The correlation between stock solution concentration and thickness of manufactured layers was tracked for both precursors as well as their difference in morphology of the final films and other properties. In particular, conformality and optical properties are better for Tiacac. Slightly lower refractive index of Tiacac-based titania reduced the reflective losses from 7.3 to 6.9% effectively. The obtained layers were used for inorganic solar cells of CsPbBr3 perovskite to finally settle the issue of optimal thickness and precursor. It is interesting that despite the supremacy in investigated properties of commonly used of the precursor Tiacac, the results of the cells pointed to the Tieth. The efficiency of the champion cell is 6.08% for Tieth, while 5.62% is noted for Tiacac. Trying to figure out this riddle, we shed a new light on the phenomena going on the ETL/inorganic perovskite interface investigating nanoroughness.
