Despite decades of research, spinal cord injury (SCI) still causes irreparable damage to the human body. Key challenges that must be overcome include the glial scars and inflammatory responses within the injury site that hinder the regeneration and extension of neurons following SCI. Transplantation of neural stem cells (NSCs) represents a promising SCI therapy, but these approaches still do not result in comprehensive recovery due to the limited neuronal differentiation of NCSs. Recently, functional scaffolds have been combined with NSCs to treat SCI. Accordingly, we therefore fabricated elastic poly (sebacoyl diglyceride) (PSeD) scaffolds with similar mechanical properties to natural spinal cord. Then, poly (sebacoyl diglyceride)-isoleucine-lysine-valine-alanine-valine-serine (PSeD-IKVAVS) was coated on the PSeD scaffolds to create a bioactive interface. The resultant scaffolds loaded with NSCs were implanted in a complete transection model of SCI in the rat. Graft integrated well with host spinal cord. Grafted NSCs exhibited neuronal differentiation rather than typical scar and very few inflammatory cells infiltrated the lesion site, leading to the significant functional recovery of the rats in 4 weeks. Next, our in vitro analyses showed that degradation products of PSeD-IKVAVS promoted NSCs differentiate into neurons, inhibited neuronal apoptosis induced by hydrogen peroxide, and alleviated inflammation stimulated by lipopolysaccharide (LPS). Overall, we demonstrated PSeD-IKVAVS scaffold containing the characteristics of suitable mechanical properties, bioactivity and fast degradability combined with NSCs would significantly promote neuronal regeneration indicating a novel approach for effectively treating SCI. © 2019, The Authors.

As global policy has devoted much effort to promoting energy conservation and carbon reduction over the past few decades, low energy consumption and less pollution have become the future trends. Moreover, with natural resources gradually turning deficient gradually, it is very important for Taiwan to further establish key technologies from reprocessed natural resources as soon as possible. The special geographical features of East Asia have always displayed a large amount of rice-husk, and therefore this paper investigates the green technology of thermoplastic polymerization with rice-husk. This paper clarifies the adhesive wear and tribological properties to evaluate the anti-slip performance of the reprocessed natural resources step by step and uses a self-developed reciprocating friction tester with measurement systems. To monitor the tribological behaviors between the interfaces, the responses of friction coefficient are recorded during the friction processes. After each test, wear loss is measured by an accuracy balance and OM is utilized to observe the worn surface. Therefore, the anti-slip performance of the reprocessed natural resources can be evaluated and a better agricultural economy can thus be obtained. © 2017 Trans Tech Publications, Switzerland.

Interfaces are ubiquitous in Li-ion battery electrodes, occurring across compositional gradients, regions of multiphase intergrowths, and between electrodes and solid electrolyte interphases or protective coatings. However, the impact of these interfaces on Li energetics remains largely unknown. In this work, we calculated Li intercalation-site energetics across cathode interfaces and demonstrated the physics governing these energetics on both sides of the interface. We studied the olivine/olivine-structured LixFePO4/LixMPO4 (x=0 and 1, M=Co, Ti, Mn) and layered/layered-structured LiNiO2/TiO2 interfaces to explore different material structures and transition metal elements. We found that across an interface from a high- to low-voltage material the Li voltage remains constant in the high-voltage material and decays approximately linearly in the low-voltage region, approaching the Li voltage of the low-voltage material. This effect ranges from 0.5-9nm depending on the interfacial dipole screening. This effect provides a mechanism for a high-voltage material at an interface to significantly enhance the Li intercalation voltage in a low-voltage material over nanometer scale. We showed that this voltage enhancement is governed by a combination of electron transfer (from low- to high-voltage regions), strain and interfacial dipole screening. We explored the implications of this voltage enhancement for a novel heterostructured-cathode design and redox pseudocapacitors. Copyright © 2017, The Authors. All rights reserved.

Machine learning models are changing the paradigm of molecular modeling, which is a fundamental tool for material science, chemistry, and computational biology. Of particular interest is the inter-atomic potential energy surface (PES). Here we develop Deep Potential - Smooth Edition (DeepPot-SE), an end-to-end machine learning-based PES model, which is able to efficiently represent the PES of a wide variety of systems with the accuracy of ab initio quantum mechanics models. By construction, DeepPot-SE is extensive and continuously differentiable, scales linearly with system size, and preserves all the natural symmetries of the system. Further, we show that DeepPot-SE describes finite and extended systems including organic molecules, metals, semiconductors, and insulators with high fidelity. Copyright © 2018, The Authors.

Spin-Hall effect and emergent antiferromagnetic phase transition in n-Si

arXiv

Spin current experiences minimal dephasing and scattering in Si due to small spin-orbit coupling and spin-lattice interactions is the primary source of spin relaxation. We hypothesize that if the specimen dimension is of the same order as the spin diffusion length then spin polarization will lead to non-equilibrium spin accumulation and emergent phase transition. In n-Si, spin diffusion length has been reported up to 6 μm. The spin accumulation in Si will modify the thermal transport behavior of Si, which can be detected with thermal characterization. In this study, we report observation of spin-Hall effect and emergent antiferromagnetic phase transition behavior using magneto-electro-thermal transport characterization. The freestanding Pd (1 nm)/ Ni80Fe20(75 nm)/ MgO (1 nm)/ n-Si (2 μm) thin film specimen exhibits a magnetic field dependent thermal transport and spin-Hall magnetoresistance behavior attributed to Rashba effect. An emergent phase transition is discovered using self-heating 3ω method, which shows a diverging behavior at 270 K as a function of temperature similar to a second order phase transition. We propose that spin-Hall effect leads to the spin accumulation and resulting emergent antiferromagnetic phase transition. We propose that the length scale for Rashba effect can be equal to the spin diffusion length and two-dimensional electron gas is not essential for it. The emergent antiferromagnetic phase transition is attributed to the site inversion asymmetry in diamond cubic Si lattice. Copyright © 2017, The Authors. All rights reserved.

In-situ deposition of hematite (α-Fe2O3) microcubes on cotton cellulose via hydrothermal method

Journal of Physics: Conference Series 2018年第1期985卷

Hematite microcubes with truncated edges have been successfully deposited on cotton cellulose via one-step hydrothermal process using anhydrous FeCl3 and glycine as Fe(III) precursor and chelating agent, respectively. The amount of glycine significantly affects the morphology and yield of hematite. The addition of 0.495 g of glycine to 50 ml of 0.1 M FeCl3 solution with 0.400 g of cotton resulted to hematite-deposited cellulose having ~15% hematite content. The reduction of glycine to 0.247 g increased the amount of hematite on the surface of the cotton cellulose to ~20% by weight. However, the hematite microcubes have a wide size distribution, with particle size in the range of 0.684 μm to 1.520 μm. Without glycine, hematite cannot be formed in the solution.

Spin driven emergent antiferromagnetism and metal insulator transition in nanoscale p-Si

arXiv

引用

arXiv 2017年

The entanglement of the charge, spin and orbital degrees of freedom can give rise to emergent behavior especially in thin films, surfaces and interfaces. Often, materials that exhibit those properties require large spin orbit coupling. We hypothesize that the emergent behavior can also occur due to spin, electron and phonon interactions in widely studied simple materials such as Si. That is, large intrinsic spin-orbit coupling is not an essential requirement for emergent behavior. The central hypothesis is that when one of the specimen dimensions is of the same order (or smaller) as the spin diffusion length, then non-equilibrium spin accumulation due to spin injection or spin-Hall effect (SHE) will lead to emergent phase transformations in the non-ferromagnetic semiconductors. In this experimental work, we report spin mediated emergent antiferromagnetism and metal insulator transition in a Pd (1 nm)/Ni81Fe19(25 nm)/MgO (1 nm)/p-Si (∼400 nm) thin film specimen. The spin-Hall effect in p-Si, observed through Rashba spin-orbit coupling mediated spin-Hall magnetoresistance behavior, is proposed to cause the spin accumulation and resulting emergent behavior. The phase transition is discovered from the diverging behavior in longitudinal third harmonic voltage, which is related to the thermal conductivity and heat capacity. Copyright © 2017, The Authors.
