In this paper, we present a flexible capacitive tactile sensor based on a polydimethylsiloxane (PDMS) elastomer, which is well-suited for a wide range of applications. The sensor incorporates an n-channel depletion-mode MOSFET to achieve an extended gate architecture. To enhance the sensing performance, TiO 2 nanoparticles are incorporated as nanofillers, resulting in an improved dielectric material ideal for highly sensitive capacitive pressure and tactile sensors. The 99PDMS-01TiO 2 nanocomposite (comprising 99 wt % PDMS and 1 wt % TiO 2 ) is utilized for promising flexible tactile sensor applications due to the synergistic effects between the PDMS matrix and TiO 2 nanoparticles, which enhance both the mechanical and sensing properties of the composite. The fabricated sensor exhibits a sensitivity of $\mathbf{30} \boldsymbol{\mu}\mathbf{A}/\mathbf{kPa}$ within the range of 0-10.5 kPa and a sensitivity of $\mathbf{9} \boldsymbol{\mu}\mathbf{A}/\mathbf{kPa}$ in the range of 10.5-30 kPa.

Because of their exceptional physical and thermal properties, cellulose nanocrystals (CNCs) are a highly promising bio-based material for reinforcing fillers. Studies have revealed that some functional groups from CNCs can be used as a capping ligand to coordinate with metal nanoparticles or semiconductor quantum dots during the fabrication of novel complex materials. Therefore, through CNCs ligand encapsulation and electrospinning, perovskite-NC-embedded nanofibers with exceptional optical and thermal stability are demonstrated. The results indicate that, after continuous irradiation or heat cycling, the relative photoluminescence (PL) emission intensity of the CNCs-capped perovskite-NC-embedded nanofibers is maintained at ≈90%. However, the relative PL emission intensity of both ligand-free and long-alkyl-ligand-doped perovskite-NC-embedded nanofibers decrease to almost 0%. These results are attributable to the formation of specific clusters of perovskite NCs along with the CNCs structure and thermal property improvement of polymers. CNCs-doped luminous complex materials offer a promising avenue for stability-demanding optoelectronic devices and other novel optical applications. © 2023 Wiley-VCH GmbH.

Conventional wastewater treatment systems have limitations in removing diverse micropollutants present with the complex matrix. As an alternative, advanced oxidation processes such as gamma-irradiation have been proposed. The aim of the study is to get insight into the decomposition of persistent pharmaceuticals (carbamazepine, cetirizine, tramadol) by gamma irradiation in pure water and effluent, the formation and pathway of TPs identified via suspect/non-target screening using LC-HRMS. For TPs, the environmental risk assessment was also conducted with QSAR based estimations. The decomposition effect was estimated with the removal rate and radiation chemical yield (G-value). The obtained results showed that the removal rate increased with increasing absorbed dose up to 5 kGy which completely eliminated target pharmaceuticals in pure water. However, the degradation in effluent was negatively affected by the organic matrix. By employing suspect/non-target screening techniques, a tentative identification of 30 transformation products (TPs) was achieved, providing insights into the degradation pathway. They were mainly formed through hydroxylation reaction by OH⸱. As a result of the QSAR estimation for the hazard of TPs, most of the TPs showed a lower risk than the parent compound. It indicates that the gamma-irradiation can be used as an alternative process to eliminate hardly degradable micropollutants in conventional wastewater treatment plant in a way to mitigate the environmental risk. © 2023, The Authors.

Objective: This paper aims to design, manufacture and evaluate an active insole to reduce plantar tissue loading to minimise the risk of diabetic foot ulceration for people living with diabetes. Methods: A prototype hydraulic soft robotic actuating insole was produced. It was controlled by an approximate finite element model of the participants' foot with a cost function to minimise plantar pressure loading and the pressure time integral. The system was evaluated during treadmill walking activity for 3 people (two people with diabetes and one healthy participant), measuring normal plantar stress in shoe both before and after shape changes. Results: The results from the participants demonstrate a reduction in average peak plantar pressure and pressure time integral by 35% [range from 9% - 52%] and 31% [range from 6% - 44%], respectively, at the high-risk region, whilst minimising edge effect and maintaining gait symmetry, regularity and cadence. The finite element driven controller was implemented when participants rested between walking periods, and it took less than six minutes to run. Conclusion: This study demonstrates, for the first time on diabetic participants, the feasibility of an active insole system using predictive finite element driven soft hydraulic actuators to reduce plantar loading in people with diabetes. Significance: Diabetic foot ulceration risk could be reduced using active insole technology and approximate predictive algorithms could play an important role to outwork this in real world activity. © 1964-2012 IEEE.

Developing highly sensitive and selective gas sensors for nitrogen dioxide (NO2) detection remains crucial for environmental monitoring and public health protection. Graphene-based chemiresistive sensors show promise due to their exceptional electronic properties and high surface area, which enhance gas adsorption. However, they face persistent challenges in selectivity, stability, and sensitivity characteristics. This study presents a facile one-step molecular intercalation doping approach that can effectively overcome these limitations. By intercalating carefully selected dopant molecules between graphene and flexible substrates during the wet-transfer process, we achieve uniform doping distribution while maintaining intrinsic carrier mobility. The resulting sensors demonstrate remarkable NO2 detection capabilities with a limit of detection of 1 ppb at room temperature. Importantly, the intercalated devices exhibit exceptional stability over extended periods of time and show minimal cross-sensitivity to common interfering gases. Moreover, the sensors retain their sensing characteristics under mechanical deformation, including fully transparent gas sensors with a dogbone structure, thereby enabling seamless integration into wearable monitoring systems. Our scalable fabrication process and comprehensive understanding of the intercalation doping mechanism provide a practical pathway for the development of reliable, flexible gas sensors capable of addressing real-world environmental and healthcare challenges. © 2025 Elsevier B.V.

In this study, a battery module with a chemically imbalanced cell was assessed in terms of its electrical, thermal, and electrochemical effects. This investigation was aimed at understanding the signals and internal reactions that occur when a battery system designed with an imbalanced module is in use. By conducting electrical and thermal analysis on a 2 × 2 battery module, we observed variations in the charge and discharge voltages, as well as the impact of distinct reactions during series and parallel connections. The series-connected module affected the voltage variance, while the parallel-connected module affected the temperature disparity. A comprehensive examination was conducted to ascertain whether the outcomes of the electrical and thermal property analyses corresponded to the internal chemical condition and configuration of the battery when the imbalanced modules connected in series and parallel are in operation, as well as when they age. Our research provides key insights into the performance of recycled lithium-ion batteries with an emphasis on battery module degradation reduction. This will also provide information for the process of repurposing battery electrodes from used battery modules, which is crucial for improving the efficiency of reused batteries. © 2024, The Authors.

Cu-Al alloys with varying Al contents were fabricated by directed energy deposition (DED) using two types of powders: CuNi2SiCr and Al-Mg-0.7Si. The deposition sample with 14 wt% Al was broken due to the high γ2 phase content while the rest were of good quality, without cracks or significant defects. The 6 wt% Al exhibited a typical DED melt pool microstructure, which is composed of a single α phase. As the Al mass fraction increased, the microstructure become finer, and disordered (β') and ordered (β1) needle-like martensite appeared in 8, 10, and 12 wt% Al samples. Furthermore, a β→(α+γ2) eutectoid transformation occurred at high Al content, resulting in the appearance of plum blossom-shaped γ2 phase in 10 and 12 wt% Al samples. The properties and oxide film formation on each sample were investigated using electrochemical measurements. The corrosion resistance of the samples increased with increasing Al content. Moreover, the 12 wt% Al sample exhibited the smallest corrosion rate, which is attributed to the protection of the dense Al2O3 oxide film that formed on its surface. The deposited layer of each sample exhibited three typical corrosion morphologies according to their microstructures: α-equiaxed grains were severely corroded at the grain boundaries;acicular martensite was selectively corroded due to different grain orientations and experienced dealuminization corrosion;and the plum blossom-shaped γ2 phase severely experienced dealuminization corrosion due to its rich aluminum content. This study provides effective strategies and new ideas for constructing Cu-Al alloys with excellent corrosion resistance. © 2024, The Authors. All rights reserved.
