The global quest for clean energy and sustainable processes makes advanced membrane extremely attractive for energy-intensive industrial gas separations. Here, we disclose a series of ultra-high-performance gas separation membranes (PIM-3D-TB) from novel network polymers of intrinsic microporosity (PIM) that combine the advantages of solution processible PIM and small pore size distribution (PSD) of porous organic polymers (POP), which was synthesized by in situ copolymerization of triptycene-2,6-diamine as linear part and triptycene-2,6,13(14)-triamine (TTA) as crosslinker. The resulting PIM-3D-TB membranes demonstrated outstanding separation properties that outperformed the latest trade-off lines for H 2 /CH 4 and O 2 /N 2 . They also showed an anti-trade-off effect by simultaneously enhancing gas permeability and gas-pair selectivity with increasing TTA content. The TTA crosslinking node increased the microporosity, and, shifted the PSD from the ultramicropore (<7 Å) toward the more size sieving submicropore (<4 Å) region. The post-treated TTA-75 displayed an exceptional H 2 permeability of 8000 Barrer and H 2 /CH 4 selectivity of 208. These PIM-3D-TB membranes and their design protocol have unparalleled potential in the next generation of membranes for hydrogen purification and air separations.

Spinal Cord Injury (SCI), a major cause of paralysis, currently has no effective therapies. Every year almost 500.000 people are diagnosed with SCI worldwide. he difficulty on the neuronal restoration after SCI is based on the complex cascade of events that inexorably cause a degenerative chronic stage mainly favored by the non-permissive environment and limited capacity for axonal regrowth. RISEUP, an Europen project, proposes to attain neuronal functional regeneration after SCI by an unprecedented and unique bio-hybrid-compatible electro-activated and wireless rechargeable implantable technology. RISEUP introduces high voltage microsecond electric pulses stimulations and low amplitude direct currents on a combination of stem cells, induced neural stem cells (iNSCs) and multipotent stromal cells (MSCs), whose transplantation is facilitated by an innovative scaffold biomaterial (Fig.1).

Autism Spectrum Disorder (ASD) is an early childhood disorder that affects individual ability to interact and socialize with other people. Children with ASD have problems interacting with their peers and have difficulty to exercise their social skills. In this study, a virtual reality (VR) based assistive tool was modelled and simulated using a gaming software called Dark Basic Professional (DBPro). The assistive tool was developed to support ASD children to interact and apply the social skills. Seven tasks were designed for the VR assistive tool based on three targeted skills including facial expression recognition, reading comprehension, and task delivery. As a preliminary study, only three non-ASD children were participated in the VR assistive tool experiment to analyse the tasks. The experiment results showed that all participants successfully performed five out of seven tasks. However, all participants failed to perform the video prompting task while one participant was not able to recognize the emotion from robotics-based faces in the facial expression. The results from pulse sensor showed that the heart rate was stable during the basic experiment using VR but unstable during the applied experiment and real-world discussion. There is a need to review the overall modelling and simulation technique, and the number of participants among ASD children should be increased for the future study.

Dynamic Partial Reconfiguration (DPR) proved itself for the implementation of multi-standard Software Defined Radio (SDR). Over the past few years, wireless communication standards witnessed great and rapid evolution. The market is always acquiring higher data rates and more special services. This leads to increase of design complexity, area, and power consumption. Deploying DPR technology on Field programmable Gate Arrays (FPGAs) made it feasible to design and manufacture all wireless communications standards on the same hardware. Loading each standard on demand reduces area and power consumption. This work implements SDR transceiver system for five wireless communication standards: Bluetooth, Wi-Fi, 2G, 3G, and LTE on Zynq-7000 evaluation kit. A new partitioning approach is deployed to achieve best performance for all transceivers. The new approach proves its ability to reduce the allocated area and power consumption for all chains. Power reduction for 2G and Bluetooth is 98.43%, for 3G and Wi-Fi is 79.69%, for LTE is 50.09% compared with no DPR approach.

Wearable and implantable BioMEMSs (biomedical microelectromechanical systems) have transformed modern healthcare by enabling continuous, personalized, and minimally invasive monitoring, diagnostics, and therapy. Wearable BioMEMSs have advanced rapidly, encompassing a diverse range of biosensors, bioelectronic systems, drug delivery platforms, and motion tracking technologies. These devices enable non-invasive, real-time monitoring of biochemical, electrophysiological, and biomechanical signals, offering personalized and proactive healthcare solutions. In parallel, implantable BioMEMS have significantly enhanced long-term diagnostics, targeted drug delivery, and neurostimulation. From continuous glucose and intraocular pressure monitoring to programmable drug delivery and bioelectric implants for neuromodulation, these devices are improving precision treatment by continuous monitoring and localized therapy. This review explores the materials and technologies driving advancements in wearable and implantable BioMEMSs, focusing on their impact on chronic disease management, cardiology, respiratory care, and glaucoma treatment. We also highlight their integration with artificial intelligence (AI) and the Internet of Things (IoT), paving the way for smarter, data-driven healthcare solutions. Despite their potential, BioMEMSs face challenges such as regulatory complexities, global standardization, and societal determinants. Looking ahead, we explore emerging directions like multifunctional systems, biodegradable power sources, and next-generation point-of-care diagnostics. Collectively, these advancements position BioMEMS as pivotal enablers of future patient-centric healthcare systems.

Micro-electromechanical systems (MEMs) started to dominate the interests of the industry due to the high growth of the various radio frequency (RF) systems, such as mobile telecommunication, satellite communication and other wireless devices that accrues high frequency range. In addition to the race of miniaturizing the device feature size. However, the main obstacle of enabling such devices is that not all of the MEMS technologies are compatible with integrated circuits (IC) manufacturing process. MEMs' devices that are based on acoustics waves like surface acoustic wave (SAW) and bulk acoustic wave (BAW) overcome aforementioned limitations while providing an outstanding performance. BAW resonator is a new technology raised during the last decade which shows better temperature stability compared to SAW, better selectivity, IC manufacturing process compatibility, and lower insertion loss. Filters based on BAWs show very promising results as well. However, BAW resonators still need optimization to achieve the high-quality factor also the temperature dependency is still a big problem. A novel Thin Film bulk acoustic resonator (FBAR) design is presented in this paper using aluminum nitride (AlN) as peizoelectric material and Tungsten (W) for the electrodes, with detailed electrical model and FEM simulations using COMSOL MULTIPHYSICS. In addition, Cadence Virtuoso is used to implement and simulate the electrical model. A resonance frequency of 2.4 GHZ is achieved with quality factor (QF) of 1548 and Temperature coefficient of frequency (TCF) ∼ 4.6 (ppm/ oC).

Hybrid nanofiller engineered for polymer nanocomposite are anticipated to achieve superior energy storage performance due to their diverse morphologies and electrical properties. In this study, 2D graphite nanoparticle (GnP) heterostructures were synthesized on surfaces and incorporated into poly(vinylidene fluoride) (PVDF) to develop PVDF-based composite (PVDF-GnP) using the solution casting route. At room temperature and an electric field of 60 kV/cm, the composite exhibits a maximum polarization of 0.079 μC/cm², while the discharged energy density reaches 2.22 J/cm³. The dielectric constant of 0.2 wt% GnP/PVDF at room temperature and at a frequency of 10³ Hz is ∼52, with a low dielectric loss of 0.25, approximately five times higher than that of pure PVDF (∼10 at 25 °C). Notably, the incorporation of GnP into the PVDF matrix significantly reduces AC conductivity, emphasizing its suitability for energy storage applications. Additionally, the study reveals that adding GnP does not modify the β phase of PVDF, ensuring the stability and compatibility of composite. Impedance analysis further highlights the dominance of grain boundary resistance, providing deeper insights into the electrical properties of the composite. This study contributes to a deeper understanding of GnP nanostructure and highlights their prospective use in cutting-edge nanotechnologies, especially in energy storage systems and high-density magnetic data recording. Current research is anticipated to further optimize the material for wider technological application.

In a single qubit system, a universal quantum classifier can be realised using the data-reuploading technique. In this study, we propose a new quantum classifier applying this technique to bosonic systems and successfully demonstrated it using silicon optical integrated quantum circuits. We established a theory of quantum machine learning algorithm applicable to bosonic systems and implemented a programmable optical circuit combined with an interferometer. Learning and classification using part of the implemented optical quantum circuit with uncorrelated two-photons resulted in a classification with a reproduction rate of approximately 94% in the proof of principle experiment. As this method can be applied to arbitrary two-mod N-photon system, further development of optical quantum classifiers, such as extensions to quantum entangled and multi-photon states, is expected in the future.

The primary challenge in dye-sensitized solar cells (DSSCs) is electrolyte leakage, compromising long-term stability and performance. Alternative electrolytes and encapsulation strategies have been explored to address this. In this study, we propose using nitrogen, fluorine, and sulfur-doped reduced graphene oxide (NSF-rGO) aerogel as an electrolyte encapsulator within DSSCs. The NSF-rGO aerogel was synthesized using a one-pot hydrothermal technique and serves to trap the liquid electrolyte, enhancing cell stability while maintaining conductivity. Although the initial power conversion efficiency of the NSF-rGO-based DSSC was lower than that of the conventional DSSC, it demonstrated significantly improved long-term stability. After two years, the efficiency drop in the NSF-rGO encapsulated DSSC was notably less than in the conventional design, indicating effective electrolyte retention and resistance to degradation. These results suggest that NSF-rGO aerogel encapsulation is a promising strategy for extending the operational lifespan of DSSCs and contributing to more sustainable energy solutions.
