“…It must be underlined that the CuS formation was stabilized in this form based on the step-by-step sulfur atmospheric treatment, which reduces the probability of oxygen insertion and allows an improved process control. The formation of CuS plays an important role in improving the Vis light absorption of the heterostructure assembly [41].…”

A titania-free heterostructure based on CuS/SnO2/WO3 was obtained by a three-step sol–gel method followed by spray deposition on the glass substrate. The samples exhibit crystalline structures and homogenous composition. The WO3 single-component sample morphology consists of fibers that serve as the substrate for SnO2 development. The CuS/SnO2/WO3 heterostructure is characterized by a dense granular morphology. Photocatalytic activity was evaluated under UV–Vis radiation and indicates that the WO3 single-component sample is able to remove 41.1% of acetaldehyde (64.9 ppm) and 52.5% of formaldehyde (81.4 ppm). However, the CuS/SnO2/WO3 exhibits a superior photocatalytic activity due to a larger light spectrum absorption and lower charge carrier recombination rate, allowing the removal of 69.2% of acetaldehyde and 78.5% of formaldehyde. The reusability tests indicate that the samples have a stable photocatalytic activity after three cycle (12 h/cycle) assessments. During light irradiation, the heterostructure acted as a Z-scheme mechanism using the redox ability of the CuS conduction band electrons and the SnO2/WO3 valence band holes to generate the oxidative species required for VOC removal.

“…Kaplanmış numunede ise sürtünme katsayısı direkt sabit bir değer aralığına gelmiş ve deneyin sonuna kadar bu kararlı halini bozmamıştır. Yapılan çalışmalar CuO kaplamaların sürtünmenin olduğu ortamlarda katı yağlayıcı gibi davrandığını göstermiştir [45][46][47]. Hem CuO tabakasının katı yağlayıcı gibi davranması ve hem de kaplamanın oldukça pürüzsüz ve sert olması sürtünme katsayısının işlemsiz numuneye göre oldukça düşük çıkmasına sebep olmuştur.…”

Öz: Canlı kemik ve implant arasındaki doğrudan bağ oluşumu olarak tanımlanan osseointegrasyonu iyileştirme ve malzeme üzerinde bakteri oluşumunu azaltma üzerine yapılan araştırmalar bilim dünyasının en güncel çalışmalarındandır. Osseointegrasyonu artırmada en çok kullanılan yöntemlerden biri hidroksiapatit kaplamalarken, bakteri oluşumunu azaltmada kullanılan yöntemler çeşitlilik göstermektedir. Bu yöntemlerden biri de antibakteriyel olduğu bilinen bakır oksitin hidroksiapatit içerisine gömüldüğü kaplamalardır. Bu çalışmada, 316L paslanmaz çelik yüzey üzerine darbeli lazer biriktirme (PLD) işlemi uygulanarak yüzeyde bakır içerikli hidroksiapatit ince film tabakası (HA/CuO) oluşturulmuştur. Kaplama işlemi sonrası işlemsiz ve kaplanmış numunelerin fosfat tamponlu tuz çözeltisi (PBS) ve yapay vücut sıvısı (SBF) içerisinde korozyon davranışları ve kuru ortam aşınma davranışları karşılaştırılmıştır. Yapısal karakterizasyonları taramalı elektron mikroskopu (SEM), X ışını kırınım cihazı (XRD) ve 3D profilometre kullanılarak gerçekleştirilmiştir.

“…In this study, NiSe 2 thin films were enlarged using the successive ionic layer adsorption and reaction (SILAR) method, which has not been reported previously. The SILAR method is preferred because it is a cost‐effective method that can be controlled easily, and result can be obtained in a short time [12,13]. This study aims to synthesize a NiSe 2 thin film with the SILAR method.…”

Nickel selenide thin films were grown on glass substrates at room temperature using the successive ionic layer adsorption and reaction (SILAR) method. Optical and structural analyses of the thin films were also performed. X‐ray diffraction (XRD), energy dispersive x‐ray analysis (EDAX) and scanning electron microscopy (SEM) were used for structural analysis, and UV–vis spectrometer was used for optical analysis. The XRD results indicate that the NiSe2 thin films had a polycrystalline structure. As a result of the optical analysis, the bandgap value decreased from 2.56 to 2.25 eV as the thickness increased. These results suggest that increasing film thickness improves the crystal structure of NiSe2 thin films. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.
