Abstract ：
Despite advances in the development of osteo-regenerative biomaterials, current products are vulnerable to stress-induced formation of cracks, resulting in the loss of functionality and a limited lifespan. In the present study, a strategy based on host-guest assembly was developed to fabricate a silk fibroin-based inorganic-organic hybrid hydrogel (termed SF@HG@HA) in which silk fibroin was used as a polymer template to tether host (?-cyclodextrin) and guest (cholesterol) monomers, respectively. Due to dynamic host-guest interactions, the prepared hydrogel could repair itself spontaneously when damaged, without the assistance of any external stimuli, mimicking the self-healing characteristics of native bone tissue. Furthermore, the efficient energy dissipation mechanism provided by the host-guest crosslinking strategy endowed the hydrogel with robust mechanical properties to bear substantial mechanical loading. SF@HG@HA was shown to support cell proliferation and osteogenic differentiation in vitro and accelerate bone regeneration in critical-size rat femoral defects in vivo. Together, the silk fibroin-based self-healing hydrogel with robust mechanical properties shows potential applications in the reconstruction of bone defects, which may provide new directions for the design of functional biomaterials for tissue regeneration.

Abstract ：
The use of hydrogel-based bone adhesives has the potential to revolutionize the clinical treatment of bone repairs. However, severe deficiencies remain in current products, including cytotoxicity concerns, inappropriate mechanical strength, and poor fixation performance in wet biological environments. Inspired by the unique roles of glue molecules in the robust mechanical strength and fracture resistance of bone, a design strategy is proposed using novel mineral-organic bone adhesives for strong water-resistant fixation and guided bone tissue regeneration. The system leveraged tannic acid (TA) as a phenolic glue molecule to spontaneously co-assemble with silk fibroin (SF) and hydroxyapatite (HA) in order to fabricate the inorganic-organic hybrid hydrogel (named SF@TA@HA). The combination of the strong affinity between SF and TA along with sacrificial coordination bonds between TA and HA significantly improves the toughness and adhesion strength of the hydrogel by increasing the amount of energy dissipation at the nanoscale. This in turn facilitated adequate and stable fixation of bone fracture in wet biological environments. Furthermore, SF@TA@HA promotes the regeneration of bone defects at an early stage in vivo. This work presents a type of bioinspired bone adhesive that is able to provide stable fracture fixation and accelerated bone regeneration during the bone remodeling process.

Abstract ：
Black phosphorus (BP) nanosheets with unique biocompatibility and superior optical performance have attracted enormous attention in material science. However, their instability and poor solution-processability severely limit their clinical applications. In this work, we demonstrate the use of silk fibroin (SF) as an exfoliating agent to produce thin-layer BP nanosheets with long-term stability and facile solution-processability. Presence of SF prevents rapid oxidation and degradation of the resultant BP nanosheets, enhancing their performance in physiological environment. The SF-modified BP nanosheets exhibit subtle solution-processability and are fabricated into various BP-based material formats. As superior photothermal agents, BP-based wound dressings effectively prevent bacterial infection and promote wound repair. Therefore, this work opens new avenues for unlocking current challenges of BP nanosheet applications for practical biomedical purposes.

Abstract ：
Two-dimensional transition metal dichalcogenides (TMDs) have attracted rapidly increasing attention due to their fascinating properties and potential applications. However, scalable and cost-effective methods to produce thin-layer TMD nanosheets and their functional composites with environmental benignity are still limited. Herein, we develop a facile and environmentally friendly method for the scalable production of thin-layer TMD nanosheets in an aqueous medium by using silk fibroin, a natural and abundant biopolymer, as the exfoliating agent. Specifically, carboxyl-modified silk fibroin significantly improves the exfoliation efficiency, achieving the high-yield production of thin-layer MoSe2 nanosheets with good solution stabilization and excellent bio-compatibility. Strong binding interactions endow the resultant MoSe2 nanosheets with unprecedentedly high concentrations. By virtue of the solution-processability of silk fibroin, MoSe2 hybrid nanosheets are readily fabricated into macroscopic freestanding films. Furthermore, due to the superior peroxidase-like activity of MoSe2 nanosheets, MoSe2-based films show rapid and effective wound disinfection and healing efficacy with the use of low-dose H2O2 in vivo, avoiding the side effects of high-dose H2O2 in traditional medical therapy. This work may offer new opportunities to apply two-dimensional TMD nanosheets for clinical applications.

Abstract ：
Fe-doped SrMoO4 (SrMo0.94Fe0.06O4-delta), synthesized by an EDTA-glycine complexing combustion process, can be easily reduced to SrMo0.94Fe0.06O3-delta (SMF) at 850 degrees C in pure H-2 atmosphere. The incorporation of Gd0.2Ce0.8O1.9 (GDC) into SrMo0.94Fe0.06O3-delta is supposed to enhance the ionic conductivity and catalytic activity of SMF. Phase composition and chemical compatibility of SMF-GDC composite in both air and H-2 atmosphere are confirmed by X-ray diffraction test. SMF-GDC composites in different mass ratios are systematically investigated in terms of electrical conductivity, electrochemical performance and power output with the fuel cells. With the addition of GDC, the ionic conductivity is able to be improved and the lowest interfacial polarization resistance is observed to be 0.647 Omega cm(2) for SMF7-GDC3 composite anode at 850 degrees C. With SMF7-GDC(3) as anode, the single cell is able to generate a maximum power density of 530 mW cm(-2) at 850 degrees C when fed with pure H-2 (30 mL min(-1)) and demonstrates a considerable stability with the anode exposed to H-2 and upon redox cycling.

Abstract ：
Double perovskite oxides SmBaCo2-xNi3O5+delta (SBCNx) (x=0-0.5) are synthesized via an EDTA-glycine process as cathodes for intermediate temperature solid oxide fuel cells (IT-SOFCs). In this study, we investigate the effects of Ni substitution for the Co sites in SmBaCo2O5+delta (SECO) in terms of structural characteristics, electrical properties, and electrochemical performance of SBCNx. At the given temperature, the electrical conductivities of SBCNx decrease as the Ni content increases, and SBCO exhibits a maximum conductivity of 1091 S cm(-1) at 250 degrees C. The average thermal expansion coefficients (TEC) over the temperature range of 25-800 degrees C show a decreased trend from 19.96 x 10(-6) K-1 for SBCO to 16.26 x 10(-6) K-1 for SBCN0.5, while the average TEC of SBCN0.3 reaches a minimum of 15.59 x 10(-6) K-1. Generally, the power density of a single fuel cell at 600-800 degrees C decreases as the Ni content increases, whereas the polarization resistance (R-P) of SBCNx on a Sm0.2Ce0.8O1.9 (SDC) electrolyte is enhanced. Among all of the samples, SBCN0.3 exhibits a combination of low thermal expansion (15.59 x 10(-6) K-1), a reasonably low R-P value (0.0464 Omega cm(2) at 800 degrees C) and high power density (536 mW cm(-2) at 800 degrees C); thus, it may be a promising candidate for IT-SOFCs.

Abstract ：
SmBaCo1.7Ni0.3O5+delta-xSm(0.2)Ce(0.8)O(1.9) (SBCN-xSDC, x = 0-50 wt.%) composite cathodes were prepared and characterized for potential use in intermediate-temperature solid oxide fuel cells (IT-SOFCs) based on an SDC electrolyte. The electrical conductivity and the thermal expansion coefficient (TEC) decreased with an increase in the SDC content of SBCN-xSDC composite cathodes. TEC values decreased from 15.59 x 10(-6) K-1 for SBCN to 13.17 x 10(-6) K-1 for SBCN-50SDC. Furthermore, the addition of SDC to the SBCN cathode improved its electrochemical performance. Among others, the SBCN-20SDC showed the lowest polarization resistance of 0.0272 Omega cm(2) at 800 degrees C; an anode-supported single-cell configuration of Ni-SDC/SDC/SBCN-20SDC obtained a maximum power density of 628 mW cm(-2) at 800 degrees C. Even when the content of SDC was raised up to 50 wt.%, the electrochemical performance of SBCN-SOSDC still exceeded that of pure SBCN. These results indicated that the SBCN-xSDC composite cathode is a promising material for ITSOFCs. Copyright (C) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.

Abstract ：
The cobalt-free layered perovskite oxides Sm1-xLaxBaFe2O5+delta (x = 0-0.5) (SLBFx, for short) have been systematically investigated to evaluate the feasibility of using them as cathodes for intermediatetemperature solid oxide fuel cells (IT-SOFCs). SLBFx powders with an orthorhombic structure were synthesized by the EDTA-glycine combustion method and were observed to be compatible with LSGM and SDC electrolytes below 1250 degrees C. The electrical conductivities of the SLBFx samples significantly increased with the substitution of La for Sm, with the highest conductivity of 37.8 S cm(-1) obtained for the SLBF0.5 sample at 600 degrees C. Of the La-doped SmBaFe2O5+delta series samples, SLBF0.2 displayed the lowest thermal expansion coefficient (TEC) and the minimum electrode polarization resistance, with values of 16.51 x 10(-6) K-1 in the 50-800 degrees C range and 0.24 Omega cm(2) at 750 degrees C, respectively. The anodesupported single cell with SLBF0.2 as the cathode was able to generate a maximum power density of 558 mW cm(-2) at 800 degrees C in humidified H-2. All things considered, SLBFx materials are good candidates for cobalt-free cathodes in IT-SOFCs.
