Direct 3d printing for functional modules and their assembly into an integrated microfluidic device.
Ultrasound-assisted synthesis of a graphene oxide (GO)–manganese nanocomposite (GO–Mn3O4) was conducted without further modification GO or employing secondary materials. With the nanoplate as support, potassium permanganate oxidizes carbon atoms in support and gets reduced to Mn3O4. An intensive ultrasound method could reduce number reaction steps temperature, enhance rate furthermore achieve Mn3O4 phase. The composite characterized by X-ray diffraction (XRD), photoelectron spectroscopy...
In this work, we report on a simple and scalable process to synthesize the core-shell nanostructure of MoS2@N-doped carbon nanosheets (MoS2@C), in which polydopamine is coated MoS2 surface then carbonized. An intensive investigation using transmission electron microscopy Raman spectroscopy reveals that as-synthesized MoS2@C possesses nanoscopic ultrathin layer sheets with thin conformal coating layers (∼ 3 nm). The demonstrates superior electrochemical performances as an anode material for...
An efficient strategy for immobilizing proteins on a gold surface was developed by employing the binding polypeptide (GBP) as fusion partner. Using enhanced green fluorescent protein (EGFP), severe acute respiratory syndrome coronavirus (SARS-CoV) envelope (SCVme), and core streptavidin (cSA) of Streptomyces avidinii model proteins, specific immobilization GBP-fusion onto nanoparticles generation nanopatterns bare were demonstrated. The GBP-fused SCVme bound to successfully interacted with...
There are many empirical equations for predicting martensite start temperature (Ms) and the kinetics models of martensitic transformation plain carbon low alloy steels. The Ms only dependent upon chemistry, while based on degree undercooling below temperature. However, prior austenite grain size (AGS) is also expected to influence both as it does in diffusive transformations. In this study, herefore, a steel with different sizes were investigated using dilatometer. new equation model...
Abstract Gastric cancer (GC) is a common aggressive malignant tumor with high incidence and mortality worldwide. GC classified into intestinal diffuse types according to the histo-morphological features. Because of distinctly different clinico-pathological features, new therapy strategies in vitro preclinical models for two pathological variants necessary. Since extracellular matrix (ECM) influence biological behavior cells, we hypothesized that might be more similarly modeled 3D rather than...
For animal PET systems to achieve high sensitivity without adversely affecting spatial resolution, they must have the ability measure depth-of-interaction (DOI). In this paper, we propose a novel four-layer system, and present performances of modules built verify concept system. Each layer in system has relative offset half crystal pitch from other layers. Performances detector were estimated using GATE Monte Carlo simulation code. The proposed consists six H9500 PMTs, each which contains...
ZnSe/ZnS core/shell quantum dots (QDs) with efficient blue emission are in situ synthesized using a novel microfluidic reaction system. This advances research on both simple one-step synthesis of QDs and their production thermoplastic-based systems. Furthermore, QD light-emitting diodes (LEDs) demonstrated as wavelength converters. For the continuous (QDs), continuous-flow systems have been recognized an effective alternative strategy to conventional batch due precise controllability...
Carbon-based electrochemical double-layer capacitors and pseudocapacitors, consisting of a symmetric configuration electrodes, can deliver much higher power densities than batteries, but they suffer from low energy densities. Herein, we report the development high density supercapacitors using an asymmetric Fe2O3 MnO2 nanoparticles incorporated into 3D macroporous graphene film electrodes that be operated in safe low-cost aqueous electrolyte. The gap working potential windows enables stable...
The flexible sensing platform is a key component for the development of smart portable devices targeting healthcare, environmental monitoring, point-of-care diagnostics, and personal electronics. Herein, we demonstrate simple, scalable, cost-effective strategy fabrication electrode based on waste newspaper with conformal coating parylene C (P-paper). Thin polymeric layers over cellulose fibers allow P-paper to possess improved mechanical chemical stability, which results in high-performance...
