0001) compared to the drug-free and alginate controls. In addition, HBMSC-laden 3D printed scaffolds were found to significantly (p less then 0.0001) support bone tissue formation in vivo compared to acellular and cast scaffolds. These studies illustrate the potential of nanoclay-based bioink, to produce viable and functional constructs for clinically relevant skeletal tissue regeneration.

The fabrication tolerance of SiH MDGs is from 2 to 4 times greater than that of TiO2MDGs, because the higher refractive index of SiH has stronger ability to restrain electric fields. It was further revealed in these studies that a SiH MDG with positive trapezoidal errors has minor influence on high diffraction efficiency bandwidth. Finally, a SiH MDG was prepared without iterative corrections. Although large fabrication errors of grating width and cross-sectional shape existed, it still had a 146 nm bandwidth with diffraction efficiency over 97%, which verifies the robustness of the proposed SiH MDG. © 2020 IOP Publishing Ltd.The transition metal dichalcogenides (TMDCs) have been intensively investigated as one of promising nanoelectronic and optoelectronic materials. However, the pervasive adsorbates on the surface of monolayer TMDCs, including oxygen and water molecules from the ambient environments, predominated degrade the device performance, in particular, under the cryogenic temperature, and the precise device application, such as gas sensor and ultrasensitive photodetectors. In this work, the effect of laser irradiation on the transport and photoresponse of monolayer MoS2 and WSe2 devices is investigated as a straightforward approach to remove the physically adsorbed contaminations. Compared with vacuum pumping and in-situ thermal annealing treatment, the field-effect transistors with the laser annealing show more than one order of magnitude higher on-state c. © 2020 IOP Publishing Ltd.Low dimensional superconductors have many unusual properties. When 0-dimensional superconductors reach to nanometer scale, the superconducting energy gap could be enhanced due to the shell effects. At the same time the single electron coulomb blockade effect could also be observed on metal nanoparticles if they are weak coupling to environment. So, if a superconducting nanoparticle is isolated well from the environment, the superconducting gap and the coulomb gap would couple together, making the tunneling spectrum more complicated and interesting. Here Sn nanoparticles were deposited on surface of STO (111). The charge energy of a nanoparticle mainly depends on its size and is comparable to the superconducting gap when the isolated particle is large enough. The superconducting energy gap can be deduced from the coupling tunneling spectrum and shell effect is observed. The method to deduce the superconducting gap here is more simple and precise than that obtained by theoretical fitting. The isolation of the superconducting nanoparticles from environment together with their high critical field and enhanced superconductivity made them an ideal platform to test some fundamental physics, especially the properties of Majorana fermions. © 2020 IOP Publishing Ltd.Laser-based angle-resolved photoemission spectroscopy and two-photon photoemission spectroscopy are employed to study the valence electronic structure of the Weyl semimetal candidateTd-WTe2along two high symmetry directions and for binding energies between ≈ -1 eV and 5 eV. The experimental data show a good agreement with band structure calculations. Polarization dependent measurements provide furthermore information on initial and intermediate state symmetry properties with respect to the mirror plane of theTdstructure of WTe2. © 2020 IOP Publishing Ltd.Nanomaterial structures are highly contributive in TEVS due to their ability to mimic the nano-scale dimension of the natural extra-cellular matrix (ECM) and the existing mechanical match between the native blood vessel and the scaffold as a vascular graft. The aim of this study was developing and mechanically improving of the nano-fibrous triad-hybrid scaffolds with different composite ratios of the polyethylene terephthalate (PET), polyurethane (PU) and polycaprolactone (PCL). The morphological, biological, mechanical and, biomechanical properties of the neat and hybrid structures were examined using SEM, DSC, FTIR, Tensile, Compliance, Burst pressure, MTT assay and, implanted the specimens under rat skin to explore the immune system in vivo. Results showed that the fiber diameter and porosity changes in the triad-hybrid electrospun scaffold ranged within 388 ± 88 to 547 ± 89 nm and 56.60 ± 2.06 % to 75.00 ± 1.94 %, respectively. In addition, the change's range of the tensile and force in the scaffolds were within 2.7 ± 0.44 to 5.27± 0.83 MPa and 2.68 ±0.19 to 10.03± 0.75 MPa, respectively. Also, the compliance and burst pressure of the structures were reported 4.05 ± 0.21 to 7.09 ± 0.49 and 1623 ± 329 to 2560 ± 121 mmHg, respectively. According to the MTT assay, high cell viability was observed on the triad-hybrid structures with a high percentage of PET when compared to that of PU. Findings of this research demonstrate that PET/PU/PCL triad-hybrid vascular scaffold has enough potential to be used in vascular tissue engineering application. © 2020 IOP Publishing Ltd.OBJECTIVE Smartphone devices may enable out-of-clinic assessments in chronic neurological diseases. We describe the FLOODLIGHT Draw a Shape (DaS) Test, a smartphone-based and remotely administered test of Upper Extremity (UE) function developed for people with multiple sclerosis (PwMS). This work introduces DaS-related features that characterise UE function and impairment, and aims to demonstrate how multivariate modelling of these metrics can reliably predict the 9-Hole Peg Test (9HPT), a clinician-administered UE assessment in PwMS. APPROACH The FLOODLIGHT DaS test instructed PwMS and healthy controls (HC) to trace predefined shapes on a smartphone screen. A total of 93 subjects (HC, n=22; PwMS, n=71) contributed both dominant and non-dominant handed DaS tests. PwMS subjects were characterised as those with normal (nPwMS, n=50) and abnormal UE function (aPwMS, n=21) with respect to their average 9HPT time (≤ or >22.7 [s], respectively). L1-regularization techniques, combined with linear least squares (OLS, IRLS), or non-linear Support Vector (SVR) or Random Forest (RFR) regression were investigated as functions to map relevant DaS features to 9HPT times.
