Intriguingly, excellent flexibility and stability have been achieved as MoS2_F PD retains 91.4% of the initial efficiency even when bent to 151° and retains 92.5% of the initial efficiency even after 1000 bending cycles. Therefore, by a low-cost process, this work demonstrates an innovative avenue to fabricate a self-powered flexible photodetector with excellent light absorption, broadband response, flexibility, and stability, which is of great practical significance for optoelectronic applications in various environments.In this study, an ion depleted zone created by an ion-selective membrane was used to impose a high and uniform constant extracellular potential over an entire ∼1000 cell rat cardiomyocyte (rCM) colony on-a-chip to trigger synchronized voltage-gated ion channel activities while preserving cell viability, thus extending single-cell voltage-clamp ion channel studies to an entire normalized colony. Image analysis indicated that rCM beating was strengthened and accelerated (by a factor of ∼2) within minutes of ion depletion and the duration of contraction and relaxation phases was significantly reduced. After the initial synchronization, the entire colony responds collectively to external potential changes such that beating over the entire colony can be activated or deactivated within 0.1 s. These newly observed collective dynamic responses, due to simultaneous ion channel activation/deactivation by a uniform constant-potential extracellular environment, suggest that perm-selective membrane modules on cell culture chips can facilitate studies of extracellular cardiac cell electrical communication and how ion-channel related pathologies affect cardiac cell synchronization. The future applications of this new technology can lead to better drug screening platforms for cardiotoxicity as well as platforms that can facilitate synchronized maturation of pluripotent stem cells into colonies with high electrical connectivity.This study aims to evaluate the changes in phenolic acids, lignans and tocopherols of sesame seeds during 0-6 days of germination by monitoring the activities of phenolic metabolism-related enzymes and the expression of key genes in the tocopherol synthesis pathway. Sesamol, which is the most active lignan antioxidant, greatly increased, and most of the phenolic acid contents increased to varying degrees after germination. Correspondingly, the related enzymes, including phenylalanine ammonia-lyase (PAL), cinnamate-4-hydroxylase (C4H), and 4-coumaratecoenzyme A ligase (4CL), were activated. Germination also promoted the conversion of γ-tocopherol to α-tocopherol with the expression of related genes changed. Additionally, there was a high correlation between the tocopherol content and the relative expression levels of key genes. The germination process also increased the bio-accessibility of lignans and tocopherols. Therefore, germination can be utilized to improve the nutritional value of sesame-related products.Roll-to-roll UV nanoimprint lithography has superior advantages for high-throughput manufacturing of micro- or nano-structures on flexible polymer foils with various geometries and configurations. Our pilot line provides large-scale structure imprinting for cost-effective polymer biochips (4500 biochips/hour), enabling rapid and multiplexed detections. A complete high-volume process chain of the technology for producing structures like μ-sized, triangular optical out-couplers or capillary channels (width from 1 μm to 2 mm, height from 200 nm up to 100 μm) to obtain biochips (width 25 mm, length 75 mm, height 100 μm to 1.5 mm) was described. The imprinting process was performed with custom-developed resins on polymer foils with resin thicknesses ranging between 125-190 μm. The produced chips were tested in a commercial point-of-care diagnostic system for multiplexed DNA analysis of methicillin resistant Staphylococcus aureus (e.g., mecA, mecC gene detections). Specific target DNA capturing was based on hybridisation between surface bound DNA probes and biotinylated targets from the sample. The immobilised biotinylated targets subsequently bind streptavidin-horseradish peroxidase conjugates, which in turn generate light upon incubation with a chemiluminescent substrate. To enhance the light out-coupling thus to improve the system performance, optical structures were integrated into the design. The limits-of-detection of mecA (25 bp) for chips with and without structures were calculated as 0.06 and 0.07 μM, respectively. Further, foil-based chips with fluidic channels were DNA functionalised in our roll-to-roll micro-array spotter following the imprinting. This straightforward approach of sequential imprinting and multiplexed DNA functionalisation on a single foil was also realised for the first time. The corresponding foil-based chips were able to detect mecA gene DNA sequences down to a 0.25 μM concentration.The electrochemical behavior and electrodeposition of indium was investigated at 26 °C and 160 °C from a solution composed of indium(iii) methanesulfonate and dimethylsulfoxide (DMSO). Indium(iii) methanesulfonate was synthesized from indium(iii) oxide and methanesulfonic acid (MSA). learn more Cyclic voltammetry, quartz crystal microbalance measurements and rotating ring disk electrode experiments indicated that reduction of indium(iii) to both indium(i) and indium(0) occurs. Yet, reduction to metallic indium was found to be the predominant process. Deposited indium could be stripped to indium(i). This unstable species disproportionated to indium(iii) and indium(0), leading to the formation of micron-sized metallic indium particles in the electrolyte. At 26 °C, indium deposited on glassy carbon as smooth, flat films whereas at 160 °C, it deposits as droplets.Self-oscillating chemical reactions are dynamical reaction-diffusion systems that show immense potential in the design of synthetic soft materials with biomimetic functionalities. The Belousov-Zhabotinsky (BZ) reaction is one such reaction, where the periodic change in the redox state of the metal ion catalyst drives the rhythmic chemical oscillations. Inspired by the exceptional properties of graphene, specifically its catalytic activity for redox reactions, we investigate the effect of graphene-based nanocomposites on the dynamics of the BZ reaction. In particular, we synthesized catalytic mats by decorating ceria nanoparticles (CeNPs) on graphene-based nanosheets, thereby creating 0D-2D heterostructures and subsequently, incorporate these catalytic mats into the BZ reaction. Our investigations reveal that CeNP decorated nanocomposites significantly enhance the oscillating frequency of the BZ reaction, not only compared to the traditional solution-based catalysts but also compared to the bare graphene-based nanosheets.
