“…The strain value of the ZnO/Au nanotextured Janus nanowire was reduced nonmonotonically. Generally, the strain value obtained for the ZnO/Au nanotextured Janus nanowire was lower than the as‐synthesized ZnO nanowire, which shows that the surface of the ZnO/Au nanotextured Janus nanowire was smoother than the as‐synthesized ZnO nanowire 29 . From the strain value obtained, it can be concluded that crystalline quality of the ZnO/Au nanotextured Janus nanowire was superior to the as‐synthesized ZnO thin film and is good agreement with Swapna et al 30 .…”

A "Janus particle" refers to the production of two materials in a single system and shows a difference in physical characteristics, and two surfaces participate in the formation with different chemistries. This research generated the Janus using a hybrid of zinc oxide (ZnO) and gold (Au) on the sensor surface toward making high-performance DNA sensors. The Janus ZnO/Au-textured film was synthesized via the one-step sol-gel method, which involves a suitable ratio of a mixture of ZnO sol seed solution. The synthesized Janus ZnO/Au-textured film undergoes a low-temperature aqueous hydrothermal route to synthesize quasione-dimensional nanowires. The average grain size in the Janus ZnO/Au nanotextured wire was 41.60 nm. The fabricated nanotextured wire was further optimized by tuning the thickness and characterized by XRD and high-resolution microscopy. Electrical characterization was conducted on the Janus ZnO/Au nanotextured wire coupled with an interdigitated electrode sensor to detect the specific leptospirosis DNA strand. The generated device is capable of detecting lower DNA concentration at 1 × 10 -13 M with a sensitivity of 8.54 MΩ M -1 cm -2 .The high performance is attained on linear concentrations of 10 -6 -10 -13 M with the determination coefficient, "I = 135437.63C−3609.07" R 2 = 0.9551. A potential strategy is proposed as a base for developing different high-performance sensors.

“…Previous reports indicated an oxide layer on/in which noble metal films or particles were deposited. [28][29][30] However, to the best of the authors' knowledge, these reports show improvements in functional properties but not the interfacial reaction. In the present study, in the ELP-Cu/ZnO (10 nm)/ glass stack, Cu and Si distributed uniformly, as shown in Fig.…”

This study demonstrated that a thin ZnO layer functions as a strong adhesion layer between Cu and glass, even when Cu films are formed near room temperature. The adhesion strength was studied with a scratch tester and the films and interfaces were characterized by scanning transmission electron microscopy. The origin of the high adhesion strength was discussed in terms of the presence of an extremely thin (approximately 10 nm) intermixing layer consisting of Cu, Pd, Zn, O, and Si.

“…Reversed-Flow Inverse Gas Chromatography (RF-IGC) has been used to study different phenomena and determine a series of physicochemical quantities [6,7,[14][15][16][17][18][19][20]. This work falls within the scope of the investigation of degradation phenomena concerning building and cultural heritage materials, focused its attention on studying the degradation-conservation of two marble statues of Greek Archaeological Museum, that of Kavala near Salonica.…”
