Carbon nanotube field effect transistor (CNFET) performance is primarily influenced by a variety of characteristics, such as nanotube diameter, operating voltage, pitch, the number of tubes, dielectric constant, and contact materials. In this study, the dielectric constant and the number of carbon nanotubes (CNTs) were emphasized to analyze the propagation delay and average power dissipation of basic logic gates. Zirconium dioxide (ZrO2), hafnium oxide (HfO2), and silicon dioxide (SiO2) were used as dielectric materials. In this experiment, the Stanford CNFET model was utilized, and variable factors such as the number of CNTs and the dielectric constant (Kox) accumulated on the nanotube gate's surface were diversified. The correlation coefficients of the delay, the average power, and the CNT numbers were also presented. Furthermore, the multi-objective genetic algorithm and the Rmethod were utilized to find the optimal Kox and the number of CNTs for minimizing the average dissipation power and the propagation delay of some logic gates designed with CNFET. For all the gates considered, the optimal number of CNTs is 4 while the dielectric constant is within the ranges of 19 to 24. © 2023 IEEE.

Titanium dioxide (TiO₂)/nitrogen-doped graphene (NG) nanocomposite is prepared via a solvent-free hydrothermal reaction. The resulting TiO₂/NG materials exhibit a reduction of the band gap energy compared to pristine TiO₂ from 3.27 eV to 2.69 eV. These materials are characterized by scanning transmission electron microscopy (STEM), energy dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS). To prepare biopolymer films with photocatalytic properties, TiO₂ and NG are mixed with biodegradable chitosan and spin-coated on a silicon wafer. Film roughness and thickness are evaluated by atomic force microscopy (AFM). These films are then tested for ciprofloxacin photodegradation by irradiating with visible light. In comparison to the TiO₂/chitosan films, the addition of NG substantially enhances photodegradation efficiency by up to 34 % upon the addition of 5 % w/w of NG. Furthermore, this film is shown to be a good substrate for biomarker detection using laser desorption ionization mass spectrometry (LDI-MS). In summary, this nanocomposite-biopolymer film provides good photocatalytic activity towards ciprofloxacin degradation and enhances the ionization efficiency of peptide biomarkers in LDI-MS owing to high efficiency of laser absorption/desorption. This nanocomposite film might be useful for environmental-related and medical application. © 2024 Elsevier B.V.

Cellulose waste was considered as a natural polymer with good biocompatibility, biodegradability, non-toxicity, which has been extensively employed in sensor research. The advantages of cellulose waste for substrate particularly in terms of portability, sensibility and cost effectiveness provided the high demand of electronic device manufacturing. Utilization of cellulose waste as a substrate in sensor was classified into various sectors such as colorimetric and electrochemical sensors. From the fundamental point of view, cellulose was successfully prepared from either agricultural or municipal waste. It was remarkable to note that purified cellulose can be employed as a platform of disposable substrate. It can be effectively replaced the traditional substrate which is commonly prepared from flat glass sheet. The interest of utilization of cellulose waste was considered as an eco-friendly process. It has given rise to a novel generation of green technology. Herein, an overview of circular economy aspect of cellulose waste, background of cellulose, surface functionalization and development of cellulose-based composite, potential and application of cellulose were therefore presented aiming to significantly provide the meaningful roadmap of cellulose waste for working as a substrate for colorimetric and electrochemical sensors. Then the economic viewpoint will be described. Finally, we purposed the current challenges and future prospects of cellulose based chemical sensors bringing the high value in the near future. © 2021 The Author(s)

Crosslinking gives hyaluronic acid (HA) the ability to resist digestion by hyaluronidase;thus, crosslinked hyaluronic acid (cHA) is currently the most popular soft tissue filler. Clinically trained physicians usually administer cHA to the desired site via injections. Injection into the upper dermis and epidermis layers of the skin is challenging, and cHA with a low level of crosslinking is employed to prevent the uneven look, but it comes with a shorter lifetime. We demonstrate here the synthesis of cHA and its simultaneous fabrication into cHA-detachable microneedles (cHA-DDMNs). The cHA-DDMN patch allowed for the deposition of cHA into the ex vivo porcine skin in 1 min. The non-crosslinked HA placed into the ex vivo porcine skin spread out evenly within 30 min after it was applied. In contrast, the deposited cHA demonstrated prolonged localization in the tissue. Furthermore, we demonstrated the sustained release of curcumin delivered by cHA both in vitro and ex vivo. In rats, the administration of cHA-DDMNs to the skin did not cause skin irritation and led to a significant increase in dermal thickness and collagen deposition. © 2025 Wiley Periodicals LLC.

Background: Medicinal herbs are used to cure parasitic protozoan diseases. Protozoan parasites continue difficult to treat, but diverse extracts from both terrestrial and aquatic plants have been shown to provide a variety of medical benefits for people's personal health. One of the main issues in the management of health and disease is the absence of treatment resistance in parasites. It affects millions of people's health globally, poses a threat to get worse, and threatens to cause financial losses. Drug resistance in parasites is progressively complex and challenging the treatment of parasitic disorders, which is disappointing because it does not receive serious consideration from every part of society. Methods: In this regard, our focus has been on examining the antiparasitic plants of the Asteraceae family and their potential use in the management of protozoan parasites. Results: This review is divided into a i) analysis of traditional parasite treatments using Asteraceae plants (ii) an overview of the major chemical classes found in Asteraceae and their effects on parasites;(iii) with special focus on flavonoids, terpenoids, and alkaloids, antiparasitic properties. In-depth information on isolated bioactive compounds that can inhibit protozoan parasites such Plasmodium, Leishmania, Trypanosoma, Entamoeba, and Toxoplasma is provided in this study. It also includes information on Asteraceae plant extracts that have been reported around the globe. Conclusion: These medicinal plants can be further studied to determine whether they have the potential to be turned into novel pharmaceuticals or utilised as a medicinal plant to treat a variety of protozoan diseases. © 2022 The Author(s)

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative
