Summary: In this study, nanostructured ZnO thin films were deposited on glass/FTO substrates using a simple and cost-effective spray pyrolysis technique. The structural and compositional properties of the deposited films were investigated, and it was found that they exhibited a crystalline nature with nanoflakes-like morphology. The bipolar resistive switching properties of the fabricated memristive devices were also studied, and it was observed that they showed non-ideal memristor behavior. Additionally, the ZnO-based memristive devices exhibited good non-volatile memory properties and reliable device performance.

Summary: Highly transparent and conducting polycrystalline n-type SnO2 thin films with a prominent peak corresponding to the (1 1 0) plane were deposited using the simple spray pyrolysis technique. The films deposited at 450 degrees C showed high crystallinity, transmittance, carrier concentration, and optical limiting behavior, making them suitable for optoelectronic and nonlinear devices. The deposition temperature significantly influenced the structure, surface morphology, photoluminescence, and third-order nonlinear optical properties of the films.

Summary: In this paper, a series of thiophene derivatives with different acceptor moieties were investigated for their nonlinear optical properties. It was found that molecules with extended conjugation length and nitro or dicyano groups as acceptors exhibit profound intramolecular charge transfer. These derivatives showed promising potential for optoelectronic and photonic applications, with noteworthy second harmonic generation response in purely organic systems and competitive trans-cis-trans isomerization times compared to commercial azobenzenes. By making small changes in the design of the acceptor moiety, it is possible to efficiently control and tailor the nonlinear response of the molecules.

Summary: Ammonia (NH3) production, storage, and transportation are susceptible to leaks, posing risks to the environment and human life. Detecting NH3 within the exposure limit is crucial for eliminating health hazards. Thin films of zinc ferrite (ZF) were deposited using spray pyrolysis at different substrate temperatures. The film deposited at 225 degrees C showed a good sensing response to 25 ppm of NH3 and exhibited stability over 90 days. This research demonstrates that ZF thin films can effectively detect NH3 in the environment.

Summary: This work explores the piezoelectric response of ZnO thin films deposited by ultrasonic spray pyrolysis with a preferential orientation at the c-axis. The results show that higher temperatures lead to improved crystalline film quality and grain size. The angular distribution of the crystals on the substrate plane deviates slightly from the normal at higher temperatures. Moreover, a prototype based on ZnO thin films was fabricated to measure the piezoelectric response, and samples with better crystallinity and high resistivity exhibit the most intense measured piezoelectric voltage.

Summary: Designing heterostructure materials at the nanoscale is a well-known method to enhance gas sensing performance. In this study, ZnO/SnO2 heterostructures were grown on alumina substrates using the ultrasonic spray pyrolysis method. The results showed that the sensitivity of the sensor to H2S gas can be altered by changing the zinc chloride content in the precursor, and the heterostructures with a 5:1 ratio of ZnCl2 to SnCl2·2H(2)O exhibited the highest response. The gas sensing mechanism of the ZnO/SnO2 heterostructures was analyzed and attributed to the formation of the heterostructure between ZnO and SnO2.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
