To obtain the GONs low laser power were used. The GONs showed different chemical and physical properties depending from the peel used as source. Scanning electron microscopy characterization showed that the size of the GONs depends on the peel used to obtain them. The characterization obtained by energy dispersive spectroscopy showed that GONs are mainly composed of carbon and oxygen. The morphological analysis was realized through transmission electron microscopy and the formation of graphene was observed. Selected area electron diffraction patterns were used to study the crystallinity of the GONs obtained. Fourier transform infrared spectroscopy shows the chemical changes among the GONs obtained from the different peels used as source. Raman spectra demonstrate the obtention of GONs and their defect densities were estimated. The X-ray patterns suggest that the samples obtained are composed of different carbon structures. Ultraviolet-visible spectroscopy shows that the GONs has different absorptions bands related to the peels used as source. Photoluminescence analysis demonstrate that the GONs obtained from all peels has luminescent properties, those obtained from mandarin shows the greater intensity. The main emission was observed at 496 nm and is related to the characteristic graphene oxide. The electrical conductivity analysis demonstrated that only the GONs obtained from banana peels can show an enhancement in the conductivity of fluids. The results demonstrated that the nanoparticles obtained in this work can be used in the development of optoelectronic devices.</div></div>","PeriodicalId":100942,"journal":{"name":"Nano Trends","volume":"9 ","pages":"Article 100091"},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While various combinations of metals have been explored for applications ranging from aerospace and biomedical devices to micro-electromechanical systems (MEMS), it works on conventional printing processes that rely on wire or powder as raw materials, which limit their applicability in certain end-use cases. In contrast, laser decal transfer enables the precise deposition of materials without phase changes, making it particularly suitable for advanced applications where chemical and functional integrity must be maintained. Most MEMS devices are fabricated using either lithography-based processes or microfabrication systems, both of which involve phase change during fabrication. This phase change often alters the chemical and functional properties of the devices, highlighting the need for a fabrication method that preserves the original material characteristics. With advancements in technologies, a thin film-based laser decal transfer setup is yet to be fully explored for printing thin-film materials in pixelated form over substrates, enabling substrate- and material-independent processes.&lt;/div&gt;&lt;div&gt;The present work focuses on the development of a laser decal transfer-based printing process using thin film as feed material for the fabrication of MEMS devices for piezo-tribo hybrid applications. Surface modification is explored to enhance static charge retention over surfaces. Initially, a silicon wafer is coated with a sacrificial layer over which a piezo-ceramic (ZnO) is sputtered to develop a seed layer.

Finally, a ZnO-FEP-based piezo-tribo hybrid device is fabricated, tested for both piezoelectric and triboelectric responses, and further explored for hybrid device applications.

Among these “new properties”, we can cite the modulation of the free carrier concentration due to the surface charge (SC) effects. Regarding this last property, simulations have recently established that these SCs can improve the piezoelectric response of the NWs. The in-depth understanding of the relationship between the SCs and the NW piezoelectric conversion capacities is thus now a prerequisite. In this overview, we investigate the impact of the surface in sub-100 nm-wide GaN NWs, as a function of their diameter and direct environment - two characteristics known to strongly modulate the SC influence. By using a unique advanced nano-characterization tool derived from AFM equipped with a modified Resiscope module to quantify the piezo-conversion properties of NWs, we experimentally confirm that the SCs are useful for improving the piezo-response. By adjusting the NW dimensions and/or their direct environment to take advantage of the SCs, we demonstrate average outputs up to 528 mV generated per GaN NW and strongly improved electromechanical conversion efficiency, up to 43 %.
