Electrical signalling cues have an important role in regulating human metabolism. Electrical stimulation is widely used to promote tissue regeneration and functional recovery. Electroactive biomaterials and devices, which convert various physical stimuli and energy sources to electrical signalling cues, have demonstrated much potential in repairing damaged tissues such as bone, cartilage, nerves, skin, muscle, tendons and ligaments, owing to their self-powering and biomimetic properties. In this Review, we examine the design and engineering of biomimetic electroactive devices for tissue repair. We highlight the conductive, piezoelectric and triboelectric properties of materials that can be applied for regenerative engineering as well as the engineering strategies used to develop effective devices with these materials. We also discuss how electroactive materials and devices can target specific tissues and clinical applications, and the mechanisms underlying the successful regeneration of tissue with these devices. Finally, we outline the need for further work on safety, effectiveness and regulation to aid the clinical translation of electroactive devices for regenerative medicine and tissue engineering.

Double-cable conjugated polymers with near-infrared (NIR) electron acceptors are synthesized for use in single-component organic solar cells (SCOSCs). Through the development of a judicious synthetic pathway, the highly sensitive nature of the 2-(3-oxo-2,3-dihydroinden-1-ylidene)malononitrile (IC)-based electron acceptors in basic and protonic solvents is overcome. In addition, an asymmetric design motif is adopted to optimize the packing of donor and acceptor segments, enhancing charge separation efficiency. As such, the new double-cable polymers are successfully applied in SCOSCs, providing an efficiency of over 10 % with a broad photo response from 300 to 850 nm and exhibiting excellent thermal/light stability. These results demonstrate the powerful design of NIR-acceptor-based double-cable polymers and will enable SCOSCs to enter a new stage.

IOP Conference Series: Materials science and Engineering 2019年第1期600卷

作者： Farin Phoothong Anyaporn Boonmahitthisud Supachok Tanpichai Program of Petrochemical and Polymer Science Faculty of Science Chulalongkorn University Bangkok 10330 Thailand Department of Materials Science Faculty of Science Chulalongkorn University Bangkok 10330 Thailand Green Materials for Industrial Application Research Unit Faculty of Science Chulalongkorn University Bangkok 10330 Thailand Learning Institute King Mongkut's University of Technology Thonburi Bangkok 10140 Thailand

In this research, the cellulose-based hydrogels were obtained from the water hyacinth fibers (WHFs) with aids of borax as a chemical cross-linker. The chemical treatment on WHFs, confirmed by Fourier transform infrared (FT-IR) analysis and thermogravimetric analysis (TGA), exhibited the reduction of hemicellulose and lignin. The treated cellulose fibers were dissolved in the mixed solution of NaOH/urea prior to mixing with borax at the cellulose/borax weight ratio of 1/0, 1/0.5 and 1/1 to prepare cellulose-based hydrogels. The effect of borax contents on the properties of cellulose-based hydrogels was investigated. The results showed that the swelling ratio and equilibrium water content of the obtained hydrogels were similar with increasing a borax content.

Cytokines mediate and control immune and inflammatory responses. Complex interactions exist between cytokines, inflammation and the adaptive responses in maintaining homeostasis, health, and well being. On-demand, local delivery of anti-inflammatory drug molecules to target tissues provides a means for effective drug dosing while reducing the adverse effects of systemic drug delivery. This work demonstrates a proof-of-concept theranostic approach for inflammation based on analyte-kissing induced signaling, whereby a drug (in this report, aspirin) can be released upon detection of a target level of a proinfammatory cytokine(i.e. Interferon-γ (IFN-γ)) in real time. The structure-switching aptamer based biosensor described here is capable of quantitatively and dynamically detecting IFN-γ both in vitro and in vivo with a sensitivity of 10 pg mL-1. Moreover, the released aspirin triggered by the inflammatory cytokine IFN-γ is able to inhibit inflammation in the inflammatory rat model, and the releasing of aspirin can be quantitatively controlled. Herein research provides a novel and promising strategy for in vivo detection of proinflammatory cytokines and the subsequent therapeutic delivery of anti-inflammatory molecules. This universal theranostic platform is expected to achieve great potentials on personalized medicine towards treatment of various of diseases and health conditions. © 2019, The Authors.

P-156:Distinguished Student Poster:Image Flickering Reduction by Dimer and polymer Stabilization in ADS Liquid Crystal Display

When a LCD display static images, power consumption can be reduced by employing a low driving frequency. However, when the driving frequency is decreased, there is a problem that the brightness of the display may change with time, a phenomenon known as flickering. One factor responsible for the flickering issue is flexoelectric effect. We show that flickering in ADvanced Super Dimension Switch (ADS) LCD can be significantly reduced by doping a liquid crystal dimer and using polymer stabilization. We demonstrated that 2 Hz driving frequency can be used to display static images.

Zinc Oxide (ZnO) nanorods were synthesized by using zinc acetate as a precursor via thermal decomposition method and then used to prepare [email protected] nanocomposite by facile room-temperature approach using a colloidal coagulation effect. The as prepared [email protected] nanocomposite was applied to modify the working electrode surface in an electrochemical sensor of Cd 2+ and Pb 2+ for the first time. The morphologies of ZnO and [email protected] nanocomposite were characterized by transmission electron microscopy, that exhibits the nanorod shape with an average diameter of 89 ± 18 nm, uniformly dispersed and intercalated between each G layer. Furthermore, the important factors affecting on the sensor sensitivity, including [email protected] ratio, [email protected] concentration, Bi 3+ concentration and electrochemical parameters were systematically investigated using square-wave anodic stripping voltammetry. Under the optimal conditions, a linear range was found to be 10–200 μg L −1 and the detection limits were 0.6 and 0.8 μg L -1 for Cd 2+ and Pb 2+ , respectively. Eventually, it was successfully used for the simultaneous detection of Cd 2+ and Pb 2+ in real wastewater samples and the results corresponded well with a standard inductively coupled plasma-optical emission spectroscopy.

Hybrid adsorbents for COcapture were prepared by coassembling laponite（LP） nanosheets and 1-nbutyl-3-methylimidazolium chloride（BMIMCl）. The prepared BMIMCl/LP layered hybrids were systematically characterized. The interlayer distance of the BMIMCl/LP layered hybrids expanded with an increasing concentration of BMIMCl, indicating that cumulative BMIMCl was intercalated into the LP layers. The efficiency of BMIMCl toward COcapture was significantly enhanced after it was immobilized within LP layers.

Parametric solution of a small-large black hole coexistence curve

We consider the first-order phase transition of a charged anti-de Sitter black hole, and find that the equation of state with the conditions of the two coexisting phases, leads to the two coupled equations about the thermodynamic volumes of small black hole and large black hole. By solving the equations, it is found that each reduced volume is only a function of the parameter ω. All properties of the coexistence curve can be studied from the two volume functions. In particular, each thermodynamic quantity is described by a piecewise analytic function. The demarcation point is located at ωd = 12(2√3 − 3). The thermodynamic function but not its derivative, is continuous at the point. This property is completely different from that of the ven der Waals fluid. Moreover, the thermodynamic behaviors as ω → 0 are discussed. From which one can easily obtain some critical exponents and amplitudes for small-large black hole phase transitions.
