Data is the basic requirement in information derivation across all fields of study. And this is especially true for transportation engineering, where road and traffic-related data are essential for getting meaningful results. The traditional methods of road data collection involve extensive preparation, manual works, and use of paper forms. These methods are time-consuming and expensive. With the growth of information technology and the widespread availability of the internet, we have entered an era of real-time data capture and sharing. This study introduces a user-friendly mobile application, GetMap, designed for real-time road data collection and sharing. The Android based app records users travel path and also collects road related data and uploads the information to Firebase cloud server. App’s key functionalities include recording travel tracks, adding road inventory and cross-sectional details, and marking points of interest with photographs. The app outputs are generated as KML files and Excel sheets, facilitating facile integration with GIS platforms. Getmap will be an effective tool for road data collection agencies like Public Works Departments (PWD), transportation planners, and road safety authorities.

Additive manufacturing enables customised device fabrication for emerging sensing technologies. However, printable (opto)electronic devices with sophisticated architectures, including all-printed photodiodes, face challenges in multi-material and multi-layer printing at micro- and nanoscales with low processing temperatures. Herein, we establish a nano-resolution printing method based on electrohydrodynamic printing (EHDP) to deposit inks from the colloidal nanocrystal (NC) library, followed by in situ room-temperature ligand exchange to functionalise the NC solids. This general approach enables layer-by-layer printing with wide selections of NC inks, ligand reagents, substrates, and device architectures. Chemical-treatment-induced contraction and densification grants printed Ag NC structures electrical conductivity and an achievable feature size and filling ratio of 70 nm and 75%, respectively, constructing wide-gamut structural colour gratings. By exploiting Ag, Au, PbS, and ZnO NCs and compact ligands, we demonstrate all-printed multi-layer infrared photodiodes with sub-10-µm pixel sizes. The nano-printing assembly of hetero-NCs promises the facile integration of multi-functional micro-nano devices.

Ghanaian traditional music plays a vital role in various aspects of life, including festivals, funerals, storytelling, and other communal activities, serving as a repository of the nation’s cultural heritage. In this digital era, the representation and documentation of this music on digital platforms are crucial for its continued relevance and accessibility, as the digital space has become a competitive source of information. While numerous audio and visual recordings of Ghanaian traditional music exist on digital platforms, there is a need to analyse these recordings and their effectiveness for music instruction and related activities. The discographic design was employed in this study to examine the audio and visuals of Ghanaian traditional music elements on digital platforms. It also explored the conditions under which these recordings were made, revealing both strengths and limitations in their technical and methodological aspects. Findings highlighted issues such as poor sound quality, inadequate camera work and insufficient technical expertise. The study concluded that these issues hinder the effective use of these recordings for educational and artistic purposes on digital platforms. It recommends a standardised approach to recording, one that incorporates objective methodologies, multi-scene perspectives, stable focus, proper zooming, the integration of expert knowledge, advanced facilities, and appropriate equipment.

The prompt identification of pancreatic cancer symptoms is an ongoing clinical challenge, often leading to late diagnosis and poor prognosis. Tumor “hijacking” of the pancreatic stromal structure limits the uptake of systemic chemotherapeutics. Localized drug delivery systems (DDS) using endoluminal techniques are widely utilized, with positive early results for improved control over tumor growth. There is a need for technologies that integrate endoluminal resources and intelligent material systems to better control the spatiotemporal delivery of chemotherapeutics. The ultrasound (US)‐triggered localized release of therapeutics is demonstrated through the design of solvent traceless drug‐loaded vinylbenzyl‐functionalized gelatin (gel4vbc) nanoparticles (NPs) integrated with an electrospun fabric. Albumin‐loaded NPs encapsulated into a poly(vinyl alcohol) (PVA) coating of a poly(ε‐caprolactone) fabric, evidence tunable triggered NP delivery controlled by regulating PVA concentration (0–1 wt%) and US intensity (0–3 W·cm−2). The fixation of the NP‐coated fabric to a magnetic tentacle robot (MTR) enables the automated manipulation into a phantom pancreatic duct before the US‐triggered release of NP‐loaded albumin and MTR retraction. Albumin release is controlled by varying the surface area of the NP‐loaded MTR‐coating fabric. A novel DDS is designed for facile integration into soft robotics and US‐triggered delivery of therapeutic‐loaded NPs.

Ciwidey in South Bandung is one of the leading tourist areas that requires good transportation accessibility. This study explores the integration of special shuttle services for tourists with the West Java Trans Metro Bus Rapid Transit (BRT) system in the area. The research approach includes literature review, policy analysis, transportation planning documents, interviews with relevant stakeholders, and comparative case studies with other cities/tourist areas. The results of the study revealed several main obstacles: weak institutional synergy between related agencies, inconsistencies in regulations governing tourism and public modes, and the issue of less integrated tariffs. For example, the Semarang study shows that most BRT stops do not have adequate intermodal integration facilities and Kebumen's analysis found that 89.55% of tourists are willing to choose the tour shuttle mode if cost and comfort are guaranteed Good practices from other cities, such as the integration strategy of public services in Yogyakarta can be used as a reference. This study concludes that strengthening institutional coordination, regulatory adjustments, and integrated tariff design are needed to facilitate modal integration.

Platinum ditelluride (PtTe2) is a type‐II Dirac semimetal featuring tilted cones in its electronic band structure, which leads to intriguing electronic and optical topological properties. Here, a large area growth process is presented for the synthesis of PtTe2 films with nanoscale thickness by sputtering deposition of a Pt precursor layer and subsequent tellurization at 450 °C. Although the Pt deposition step does not pose stringent limitation on the substrate choice, it is demonstrated that the heating rate during the tellurization step can induce a significant thermal‐induced strain when the process is extended from silicon dielectric transparent silica substrates, leading to macroscopic wrinkling of the PtTe2 film. Thus, a slower tellurization process is optimized, successfully resulting in stress‐free growth even on dielectric substrates. Additionally, the same new process repeated on silicon substrates shows a threefold enhanced minimum grain size compared to the original process. These accomplishments, combined with the scalability of the growth technique and the deterministic material patterning achieved by optical lithography, are crucial for a facile integration of PtTe2 in any kind of device.

In recent years, solar-driven evaporators have gained attention as a sustainable approach to water treatment. Utilizing photothermal materials for solar evaporation represents a sustainable and practical strategy to mitigate water scarcity by leveraging the abundance of solar energy. The efficient solar-to-thermal is crucial and has been widely investigated, with the development of solar absorber materials emerging as a compelling focus due to their excellent photothermal performance. The carbon dots (CDs) have recently gathered considerable attention for their potential application in this domain. CDs exhibit several desirable properties, including broadband light absorption, high photothermal conversion efficiency, tunable surface functionalities, facile integration into substrates, ease of synthesis, and accessibility to abundant raw materials, making them a suitable candidate for this application. In this review, a brief introduction to the solar evaporator, including the mechanism and key components in solar-driven interfacial evaporation (SDIE) devices, is given, followed by a strategy of CDs synthesis, sources of CDs precursors, and their incorporation into various substrates. Moreover, the potential application of CD-based evaporators in evaporation, desalination, water purification, electricity generation, and the removal of microbes is highlighted. This study concludes by exploring the current limitations and prospective advancements in CD-assisted solar evaporation research.

ABSTRACT This paper proposes an engineering framework for sustainable retrofitting of Soviet-era heritage bathhouses through integrated greywater reuse and geothermal heat recovery systems. The study addresses the combined objectives of minimizing environmental impact and preserving the architectural integrity of water-intensive heritage facilities. Using the Arasan Bath Complex in Almaty, Kazakhstan, as a case study, I developed a modular treatment system incorporating ultrafiltration, activated carbon, and ozone disinfection for shower and pool wastewater reuse. A hybrid heating concept integrating geothermal heat pumps with greywater heat exchangers was designed and evaluated. Simulation results indicate a potential 30% reduction in freshwater consumption (30,000 m3 annually) and 29% thermal energy offset. Economic analysis shows a payback period of 5 years for water reuse and under 8 years for geothermal systems. The modular architecture complies with heritage conservation principles while delivering notable improvements in resource efficiency.

Next‐generation thermometry requires ultrahigh temperature sensitivity, precision, and microscale or nanoscale spatial resolution for bio‐calorimetry, optoelectronic sensing, quantum science, energy storage, and thermal management of electronic devices. Current thermometry approaches based on thermocouple, resistive, and optical mechanisms suffer from various problems such as large volume, low resolution, high noise level, and narrow temperature range. Microelectromechanical system (MEMS) resonators hold great potential as thermometry due to the small size, batch fabrication, and facile integration with electrical circuits. However, mainstream silicon MEMS thermometry struggles with the trade‐off between responsivity, temperature resolution, and sensitivity. In this work, we utilize the highest crystal quality single‐crystal diamond and multi‐mode resonance for MEMS cantilever thermometry to address these challenges. The resulting diamond MEMS thermometry exhibits unparalleled performance, with an ultra‐high sensitivity of ≈22 nKHz−1/2, a high temperature resolution of 100 µK, and a wide‐temperature range from 6.5 to 380 K. The groundbreaking sensing performance highlights the versatility and transformative potential of diamond MEMS resonator as the next‐generation platform for ultrahigh‐sensitivity and high‐resolution temperature sensing in microscale or nanoscale space.

ABSTRACTThe burgeoning Internet of Things demands highly customizable microbatteries (MBs) to power miniaturized electronics, yet challenges exist in fabricating ultra-small MBs and integrating customizable modules within confined areas. Herein, we report a novel photolithographic microfabrication strategy enabling the large-scale production of monolithic integrated ultra-small MBs. The approach utilizes photoresist grooves as micropattern templates and employs a non-destructive mechanical peeling process to fabricate precise MBs with a compact area of 2.2275 mm2 by using Li3V2(PO4)3 as both the cathode and the anode. These MBs demonstrate an exceptional areal capacity of 96.4 μAh cm−2 and remarkable cycling stability, retaining 88.3% of their initial capacity after 10 000 cycles. Furthermore, the method allows the facile serial integration of numerous MBs in a single step, achieving a record voltage of 182.7 V through 63 series-connected units. This breakthrough provides a scalable solution for mass-producing customizable MBs, advancing the power supply capabilities for miniature electronics with high energy density and long-term reliability.

ABSTRACTA facile synthesis, preparation, and integration of a diacrylate‐functionalized mechanophore is presented to demonstrate that a single, identical mechanophore is readily incorporated into polymer networks of various origins as a tool for identifying differences and similarities in the mechanical behavior of these networks. This work investigates polymer mechanical properties during and following stimulation of mechanofluorophore‐incorporated step and chain growth crosslinked polymers. This is achieved with an acrylate‐functionalized benzoxazole mechanofluorophore polymerized via a nucleophile‐mediated thiol‐Michael polymerization (step growth) or a photoinitiated radical acrylate homopolymerization (chain growth). These systems were tuned to have similar storage moduli by incorporating a monofunctional acrylate as a chain extender and crosslink density diluent in the chain growth network. Uniaxial tensile tests indicate that mechanophore incorporation in both systems results in an increase in the percent strain at break compared to control materials without the benzoxazole mechanophore but otherwise maintained monomer composition. Integration of the mechanofluorophore was also implemented in dynamic networks formed from step and chain growth polymerizations where the presence of disulfide bonds facilitated thermally activated bond rearrangement for stress relaxation. The presence of the mechanofluorophore in these networks did not inhibit the dynamic nature of the networks as evidenced by comparable stress‐relaxation traces.

Despite immunogenic cell death (ICD) has garnered significant attention in cancer therapy, achieving precise in vivo immunity activation and simultaneous visualization of immunotherapy processes remain significant challenges due to the difficulties in facile integration of multifunctionalities in a single nanomedicine. For this purpose, herein a self-adaptive rhodium(I) complex-based nanoplatform driven by metallophilic interactions is reported not only for near-infrared (NIR) imaging-guided cancer immunotherapy, but also as the first example of a rhodium(I)-based ICD inducer. Specifically, this nanoplatform enables high tumor enrichment by utilizing homologous targeting capability camouflaged by cancer cell membranes and facilitates enhanced in vivo NIR phosphorescence imaging. The subsequent uptake of this nanoplatform by tumor cells via endocytosis releases the antitumor rhodium(I) complex monomer, which can target directly the endoplasmic reticulum and induce a more effective type II ICD for enhanced dendritic cell maturation and cytotoxic T lymphocyte infiltration, and ultimately lead to long-acting antitumor immunity. Notably, the self-adaptive functional switch strongly supports the NIR phosphorescence imaging and cancer immunotherapy of this platform, which displays a remarkable inhibitory effect with a tumor inhibition rate of 91.2%. This study develops a facile yet robust approach toward an "all-in-one" metal-based ICD agent with visualization properties for monitoring immunotherapy.
