“…16,44,67 Yu et al 45 reported the efficacy of a graphene/Ag nanocomposite in bacteria. 39 Recently, Fiorillo et al 15 using large GO flakes, observed a dose-dependent inhibition of tumor sphere formation; interestingly, neither small nor large GO flakes affected the viability of the bulk non-CSC population of the MCF7 cells indicating the selectivity of GO toward CSCs of ovarian, prostate, pancreatic, and lung cancers as well as glioblastoma. This is the first comprehensive study showing the efficacy of GO, rGO, rGO-Ag nanocomposite, and AgNPs.…”

Background Graphene and graphene-based nanocomposites are used in various research areas including sensing, energy storage, and catalysis. The mechanical, thermal, electrical, and biological properties render graphene-based nanocomposites of metallic nanoparticles useful for several biomedical applications. Epithelial ovarian carcinoma is the fifth most deadly cancer in women; most tumors initially respond to chemotherapy, but eventually acquire chemoresistance. Consequently, the development of novel molecules for cancer therapy is essential. This study was designed to develop a simple, non-toxic, environmentally friendly method for the synthesis of reduced graphene oxide–silver (rGO–Ag) nanoparticle nanocomposites using Tilia amurensis plant extracts as reducing and stabilizing agents. The anticancer properties of rGO–Ag were evaluated in ovarian cancer cells. Methods The synthesized rGO–Ag nanocomposite was characterized using various analytical techniques. The anticancer properties of the rGO–Ag nanocomposite were evaluated using a series of assays such as cell viability, lactate dehydrogenase leakage, reactive oxygen species generation, cellular levels of malonaldehyde and glutathione, caspase-3 activity, and DNA fragmentation in ovarian cancer cells (A2780). Results AgNPs with an average size of 20 nm were uniformly dispersed on graphene sheets. The data obtained from the biochemical assays indicate that the rGO–Ag nanocomposite significantly inhibited cell viability in A2780 ovarian cancer cells and increased lactate dehydrogenase leakage, reactive oxygen species generation, caspase-3 activity, and DNA fragmentation compared with other tested nanomaterials such as graphene oxide, rGO, and AgNPs. Conclusion T. amurensis plant extract-mediated rGO–Ag nanocomposites could facilitate the large-scale production of graphene-based nanocomposites; rGO–Ag showed a significant inhibiting effect on cell viability compared to graphene oxide, rGO, and silver nanoparticles. The nanocomposites could be effective non-toxic therapeutic agents for the treatment of both cancer and cancer stem cells.

“…[ 165,166 ] BAW resonators consist of a piezoelectric film placed between two metal electrodes, inducing an acoustic wave that propagates vertically along the bulk of the piezoelectric film and forms a standing wave between the electrodes. The piezoelectric film plays an important role in MEMS systems, such as optical attenuators, [ 167–171 ] scanning mirrors, [ 172–176 ] and energy harvesters [ 177–186 ] and transducers. [ 187–190 ] To increase communication frequency to the terahertz range, small‐scale integrated photonic resonators have been studied and demonstrated, driving exploration at both the signal transmitter and receiver sides.…”

In recent years, with the further ministration of the semiconductor device in integrated circuits, power consumption and data transmission bandwidth have become insurmountable obstacles. As an integrated technology, photonic integrated circuits (PICs) have a promising potential in the post‐Moore era with more advantages in data processing, communication, and diversified sensing applications for their ultra‐high process speed and low power consumption. Silicon photonics is believed to be an encouraging solution to realize PICs because of the mature CMOS process. The past decades have witnessed a huge growth in silicon PICs. However, there is still a demand for the development of silicon PICs to enable powerful chip‐scale systems and new functionalities. In this paper, a review of the photonic components, functional blocks, and emerging applications for PICs is offered. The common photonic components are classified into several sections, including on‐chip light sources, fiber‐to‐chip couplers, photonic resonators, waveguide‐based sensors, on‐chip photodetectors, and modulators. The functional blocks of the PICs mentioned in this review are photonic memories and photonic neural networks. Finally, the paper concludes with emerging applications for further study.

power requirements. [1][2][3] The mechanical energy present in the waves and tides of the ocean can be harnessed and utilized by advanced technologies. [4][5][6] Unquestionably, the employment and harvest of ocean energy are increasingly considered a vital solution to the critical energy shortage. [7][8][9] Capturing large-scale wave energy will eventually lead to modifying the world's energy structure to end the energy crisis. [10][11][12] Ocean energy sources are being explored to provide large-scale electricity, typically over a few watts, to meet the energy demands of commercial and residential areas that face power shortages. [13][14][15] In parallel, there is a growing interest in energy harvesting technologies that can generate small amounts of power from nanowatts to milliwatts to replace conventional batteries in portable and wearable electronics. Renewable energy-based self-powered systems have progressed remarkably over the last decade. [16][17][18] The current method of ocean energy harvesting is based on electromagnetic generators (EMGs) or triboelectric nanogenerators (TENGs). [19,20] The TENGs can be an alternative power unit as they can convert various energy vibrations from the ocean into electrical output. [21,22] TENGs often produce a high voltageThe ocean holds vast potential as a renewable energy source, but harnessing its power has been challenging due to low-frequency and high-amplitude stimulation. However, hybrid nanogenerators (HNGs) offer a promising solution to convert ocean energy into usable power efficiently. With their high sensitivity and flexible design, HNGs are ideal for low-frequency environments and remote ocean regions. Combining triboelectric nanogenerators (TENGs) with piezoelectric nanogenerators (PENGs) and electromagnetic nanogenerators (EMGs) creates a unique hybrid system that maximizes energy harvesting. Ultimately, hybrid energy-harvesting systems offer a sustainable and reliable solution for growing energy needs. This study provides an in-depth review of the latest research on ocean energy harvesting by hybrid systems, focusing on self-powered applications. The article also discusses primary hybrid designs for devices, powering self-powered units such as wireless communication systems, climate monitoring systems, and buoys as applications. The potential of HNGs is enormous, and with rapid advancements in research and fabrication, these systems are poised to revolutionize ocean energy harvesting. It outlines the pros and cons of HNGs and highlights the major challenges that must be overcome. Finally, future outlooks for hybrid energy harvesters are also discussed.
