Salivary uric acid is regarded as a noninvasive biomarker of metabolic syndrome and renal disorder. Although many enzyme based assays have been developed for quantitation of uric acids, most of the biological reagents are only stable for 30 days after opening even stored at 2-8 °C. To overcome this short-lasting problem, long-lasting (more than two years), easily stored and cost-effective nonenzymatic C-dots prepared from PEI through a simple hydrothermal method were developed. Experimental results reveal that the sensitivity of the PEI C-dot assay for uric acid is higher than that of reported fluorescece and enzyme based sensors.

Global efforts to mitigate climate change emphasize the critical need to reduce atmospheric CO₂ levels and enhance carbon sinks. Mangrove ecosystems, renowned for their substantial carbon sequestration capacity, play a vital role in sequestering significant amounts of carbon. This review explores carbon fluxes in mangrove ecosystems, emphasizing autochthonous and allochthonous carbon sequestration mechanisms. Specifically, it discusses the pathways through which carbon is absorbed and stored, including biological productivity, sediment accumulation, and carbonate precipitation. Furthermore, the role of microbial communities and root systems in carbon stabilization, nutrient cycling, and methane oxidation is also examined, highlighting their significance in enhancing sequestration efficiency. Moreover, this study evaluates the factors influencing carbon sequestration efficiency in mangroves and the methods used for its quantification. Finally, this review assesses the contribution of mangroves to the global carbon budget, emphasizing their strategic role in offsetting atmospheric CO 2 and enhancing coastal ecosystem resilience. However, significant research gaps remain in understanding the mechanism of carbon transformation, the interaction between diverse carbon sources, sediment dynamics, and long-term stability of buried organic matter across varying mangrove settings.

Following the increase in the global aging population, the importance of monitoring various disease-related biomarkers at an early stage has increased to ensure the health of the elderly. In an aging society, point-of-care (POC) systems are needed to care for elderly people who have physical and mental disorders. In light of the increasing prominence of POC systems, there is a growing effort to address the limitations associated with conventional receptors in wearable devices by substituting them with molecularly imprinted polymer (MIP). MIPs are well-known synthetic receptors engineered with specific binding cavities based on the "lock and key" principle. They could be synthesized in various configurations depending on specific types of monomers and templates. Compared to conventional receptors such as antibodies and aptamers, MIPs exhibit outstanding advantages, including good stability, cost-effectiveness, ease of synthesis, reusability, and broad applicability. These advantages have led to their extensive application in biomedical healthcare devices. This review summarizes a comparative analysis of sensors utilized for the detection of disease-specific biomarkers through diverse MIP applications and methodologies. Furthermore, we evaluated recent advancements in the miniaturization of MIPs and their integration with wearable biomedical devices for comprehensive healthcare monitoring applications. Finally, we delineated the existing limitations that need to be surmounted for the effective implementation of MIP-based biomedical devices and outlined future objectives for the enhancement of wearable and wireless biomedical healthcare monitoring devices.

Physical Review B 2018年第6期98卷 064308-064308页

We studied GHz hypersound in heterostructures of SrRuO3 (SRO) and SrTiO3 (STO) by using femtosecond pulses with fluence as low as several tens of μJ/cm2. We found that the efficiency of generating hypersound in SRO, through thermal expansion, is linear up to optical fluence of a few mJ/cm2. We further investigated the propagation of acoustic pulses in the STO substrate. The acoustic properties of STO dramatically changed around the temperature of structural transition (105 K) because the generated hypersound was coupled to the softening mode. Nevertheless, our experimental results revealed that the quadratic frequency dependence of acoustic attenuation in STO, predicted by the mode-coupling theory, breaks down at tens of GHz. Finally, the refractive index of STO was experimentally obtained between 365 and 400 nm, for which there was disagreement in previous results.

Curved Cu nanowire (CCN)-based high-performance flexible transparent conductive electrodes (FTCEs) were fabricated via a fully solution-processed approach, involving synthesis, coating, patterning, welding, and transfer. Each step involved an innovative technique for completing the all-solution processes. The high-quality and well-dispersed CCNs were synthesized using a multi-polyol method through the synergistic effect of specific polyol reduction. To precisely control the optoelectrical properties of the FTCEs, the CCNs were uniformly coated on a polyimide (PI) substrate via a simple meniscus-dragging deposition method by tuning several coating parameters. We also employed a polyurethane (PU)-stamped patterning method to effectively produce 20 μm patterns on CCN thin films. The CCN thin films exhibited high electrical performance, which is attributed to the deeply percolated CCN network formed via a solvent-dipped welding method. Finally, the CCN thin films on the PI substrate were partially embedded and transferred to the PU matrix to reduce their surface roughness. Through consecutive processes involving the proposed methods, a highly percolated CCN thin film on the PU matrix exhibited high optoelectrical performance (R s = 53.48 Ω/□ at T = 85.71%), excellent mechanical properties (R/R 0 < 1.10 after the 10th repetition of tape peeling or 1,000 bending cycles), and a low root-mean-square surface roughness (R rms = 14.36 nm).

Anomalous Z2 antiferromagnetic topological phase in pressurized SmB6

Physical Review B 2018年第19期97卷 195145-195145页

作者： Kai-Wei Chang Peng-Jen Chen Department of Physics National Taiwan University Taipei 10617 Taiwan Nano Science and Technology Program Taiwan International Graduate Program Academia Sinica Taipei 11529 Taiwan and National Taiwan University Taipei 10617 Taiwan Institute of Physics Academia Sinica Taipei 11529 Taiwan

Antiferromagnetic materials, whose time-reversal symmetry is broken, can be classified into the Z2 topology if they respect some specific symmetry. Since the theoretical proposal, however, no materials have been found to host such Z2 antiferromagnetic topological (Z2−AFT) phase to date. Here we demonstrate that the topological Kondo insulator SmB6 can be a Z2−AFT system when pressurized to undergo an antiferromagnetic phase transition. In addition to proposing the possible candidate for a Z2−AFT material, in this work we also illustrate the anomalous topological surface states of the Z2−AFT phase which have not been discussed before. Originating from the interplay between the topological properties and the antiferromagnetic surface magnetization, the topological surface states of the Z2−AFT phase behave differently as compared with those of a topological insulator. Besides, the Z2−AFT insulators are also found promising in the generation of tunable spin currents, which is an important application in spintronics.

Recently, convergence of nanotechnology and sustainable approaches has emerged as promising strategy for advanced remediation of heavy metals (HMs) from water. However, engineered nanoparticles (ENPs)-derived from freshwater microalgae gained attention as viable alternative, owing their inherent metal tolerance, rapid-growth rates, and versatile metabolic capabilities. This review predominantly focuses on freshwater microalgae-mediated-ENPs, highlighting intracellular/extracellular pathways induced by biomolecules such as polysaccharides, proteins, lipids, reductases etc., which govern nanoparticle nucleation, stabilization, and functionalization. Subsequently, the review discusses significant types of ENPs including iron, silver, gold, cadmium-sulfide, iron-oxide, nanocomposites, and bio-nano-hybrids nanoparticles, which reported removal efficiency from 21 to 100% of different HMs (lead, cadmium, chromium, copper, zinc, etc.). Despite ENPs exhibit significant potential, their large-scale implementation is constrained by challenges such as scaling-up, nutrient-variability, and high turbidity of wastewater. Future research recommended to focus on optimizing biosynthesis parameters, investigating diverse microalgal-strains, incorporating hybrid nano-materials to enhance their stability, reusability, and scalability for sustainable green-technology.

Dental composite as restorative materials is mostly used because of its aesthetics, good adhesive properties, and minimal preparation. However, almost half of the composite restoration failure can be caused by a crack, which is triggered from the use of irregular and angulated silica particles as composite fillers. These also tend to decrease the Diametral Tensile Strength (DTS) value as one of the mechanical properties. This study aims to compare the DTS value of dental composite with and without PMMA fiber. Twenty samples were divided into two groups, dental composite without PMMA fiber filler as the control group (70% silica particle filler) and dental composite with PMMA fiber filler (65% silica particle filler, 5% PMMA fiber filler). The DTS test was carried out using the Universal Testing Machine (Lloyd) with 5.6 N load and 1 mm/minute crosshead speed. Then, the fracture surface of the samples was evaluated using Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) using JEOL JED-2300. The result of DTS value on the control group was 38.74±3.05 MPa while the fiber group was 28.39±3.21 MPa, which is supported by SEM observations that revealed the presence of the nanofiber on the fiber group with the percentage of the silica concentration (±30%) on the EDS observations was lower than the control group. So, it can be concluded that the fiber reinforcement has lowered silica concentration, which decreased DTS value than the control group. Further research shall investigate the fiber diameter, phase of crystallization, binding interaction between silica and fiber as filler, and also the optical properties akin to natural tooth appearances on the cervical region.
