Polyelectrolyte-surfactant complexes（PESCs） were fabricated through the interaction of poly（acrylic acid） and four different cationic surfactants or their mixtures. PESC membranes were prepared by solution casting method and were applied in ethanol recovery from aqueous solution via pervaporation. Elemental analysis（EA）, Fourier transform infrared spectroscopy（FTIR）, water contact angle（CA） measurement, differential scanning calorimetry（DSC） and X-ray scattering were employed to characterize the composition, structure and properties of PESCs. The results reveal that the investigated PESCs are similar in hydrophobicity but different in hierarchical nanostructures. In separating 5 wt% ethanol/water mixture, PESC membranes with high crystallinity will have both low flux and ethanol selectivity because of the high packing density and low permeability of crystalline regions. Meanwhile, the hierarchical nanostructures of PESC membranes change under pervaporation environment as was revealed by in situ synchrotron radiation X-ray scattering measurement. That is, the crystalline region could melt at high temperature in swelling state, thus consequently enhancing the ethanol selectivity.

Coal is the most abundant fossil fuel in the world. Because of the growth of coal mining, coal-fired power plants and coal-burning industries, the increase of the emission of particulates(coarse, fine or ultrafine)is of great concern. There is a relationship between increasing human morbidity and mortality and progressive environmental air pollution caused by these types of particles. Thus, the knowledge of the physico-chemical composition and ambient concentrations of coal-derived nanoparticles will improve pollution control strategy. Given the current importance of this area of research, the advanced characterization of this coal combustion-derived nanoparticles/nanominerals as well as hazardous elements is likely to be one of the hottest research fields in coming days. In this review, we try to compile the existing knowledge on coal-derived nanoparticles/nanominerals and discuss the advanced level of characterization techniques for future research. This review also provides some of aspects of health risks associated with exposure to ambient nanoparticles. In addition, the presence of some of the hazardous elements in coal and coal combustion activities is also reviewed.

The degeneration of dopaminergic neurons is a major contributor to the pathogenesis of mid-brain disorders. Clinically, cell therapeutic solutions, by increasing the neurotransmitter dopamine levels in the patients, are hindered by low efficiency and/or side effects. Here, a strategy using electromagnetized nanoparticles to modulate neural plasticity and recover degenerative dopamine neurons in vivo is reported. Remarkably, electromagnetic fields generated by the nanoparticles under ultrasound stimulation modulate intracellular calcium signaling to influence synaptic plasticity and control neural behavior. Dopaminergic neuronal functions are reversed by upregulating the expression tyrosine hydroxylase, thus resulting in ameliorating the neural behavioral disorders in zebrafish. This wireless tool can serve as a viable and safe strategy for the regenerative therapy of the neurodegenerative disorders.

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.

Effect of TPU soft segment molecular weight on TPU’s bead foaming behavior

引用

AIP Conference Proceedings 2020年第1期2205卷

作者： Bige Bati Emine Bursa Kucuk Mohammadreza Nofar Polymer Science and Technology Program Istanbul Technical University Maslak Istanbul 34469 Turkey Metallurgical & Materials Engineering Department Faculty of Chemical and Metallurgical Engineering Istanbul Technical University Maslak Istanbul 34469 Turkey

The bead foaming behavior of three different thermoplastic polyurethane (TPU) samples with different polyol soft-segment molecular weights was investigated through a lab-scale bead foaming reactor. These TPU samples possessed similar hard-segment content and soft-segment molecular weights of 1000, 2000, and 3500 g/mol. The evolution of the hard-segment crystallization during the isothermal saturation as well as the increased solubility of supercritical CO2 within the soft-segment region are, respectively, determinative parameters on improving the heterogeneous cell nucleation and expansion of the expanded TPU (ETPU) bead foams. The effect of saturation temperature, pressure, and time on the hard-segment crystallization and hence on the foaming behavior of TPU samples were explored. The results showed that the increase in soft-segment molecular weight increased the expansion ratio of the bead foams while the processing parameters differently influenced the hard-segment crystallization and CO2 solubility and hence the foaming behavior of ETPU foams.

Computer simulations of model systems are widely used to explore striking phenomena in promising applications spanning from physics, chemistry, biology, to materials science and engineering. The long range electrostatic interactions between charged particles constitute a prominent factor in determining structures and states of model systems. How to effciently calculate electrostatic interactions in model systems subjected to partial or full periodic boundary conditions has been a grand challenging task. In the past decades, a large variety of computational schemes have been proposed, among which the Ewald summation method is the most reliable route to accurately deal with electrostatic interactions in model systems. In addition, extensive effort has been done to improve computational effciency of the Ewald summation based methods. Representative examples are approaches based on cutoffs, reaction fields, multi-poles, multi-grids, and particle-mesh schemes. We sketched an ENUF method, an abbreviation for the Ewald summation method based on Non-Uniform fast Fourier transform technique, and have implemented this method in particlebased simulation packages to calculate electrostatic energies and forces at microand mesoscopic levels. Extensive computational studies of conformational properties of polyelectrolytes, dendrimer-membrane complexes, and ionic uids demonstrated that the ENUF method and its derivatives conserve both energy and momentum to oating point accuracy, and exhibit a computational complexity of O(N logN) with optimal physical parameters. These ENUF based methods are attractive alternatives in molecular simulations where high accuracy and effciency of simulation methods are needed to accelerate calculations of electrostatic interactions at extended spatiotemporal scales.
