3D bioprinting and the current applications in tissue engineering.

Abstract: Bioprinting as an enabling technology for tissue engineering possesses the promises to fabricate highly mimicked tissue or organs with digital control. As one of the biofabrication approaches, bioprinting has the advantages of high throughput and precise control of both scaffold and cells. Therefore, this technology is not only ideal for translational medicine but also for basic research applications. Bioprinting has already been widely applied to construct functional tissues such as vasculature, muscle, cartilage, and bone. In this review, the authors introduce the most popular techniques currently applied in bioprinting, as well as the various bioprinting processes. In addition, the composition of bioink including scaffolds and cells are described. Furthermore, the most current applications in organ and tissue bioprinting are introduced. The authors also discuss the challenges we are currently facing and the great potential of bioprinting. This technology has the capacity not only in complex tissue structure fabrication based on the converted medical images, but also as an efficient tool for drug discovery and preclinical testing. One of the most promising future advances of bioprinting is to develop a standard medical device with the capacity of treating patients directly on the repairing site, which requires the development of automation and robotic technology, as well as our further understanding of biomaterials and stem cell biology to integrate various printing mechanisms for multi-phasic tissue engineering.

Integrated Intercalation‐Based and Interfacial Sodium Storage in Graphene‐Wrapped Porous Li4Ti5O12 Nanofibers Composite Aerogel

Abstract: Sodium storage in both solid–liquid and solid–solid interfaces is expected to extend the horizon of sodium-ion batteries, leading to a new strategy for developing high-performance energy-storage materials. Here, a novel composite aerogel with porous Li4Ti5O12 (PLTO) nanofibers confined in a highly conductive 3D-interconnected graphene framework (G-PLTO) is designed and fabricated for Na storage. A high capacity of 195 mA h g−1 at 0.2 C and super-long cycle life up to 12 000 cycles are attained. Electrochemical analysis shows that the intercalation-based and interfacial Na storage behaviors take effect simultaneously in the G-PLTO composite aerogel. An integrated Na storage mechanism is proposed. This study ascribes the excellent performance to the unique structure, which not only offers short pathways for Na+ diffusion and conductive networks for electron transport, but also guarantees plenty of PLTO–electrolyte and PLTO–graphene interfacial sites for Na+ adsorption.

Near-infrared absorbing 2D/3D ZnIn 2 S 4 /N-doped graphene photocatalyst for highly efficient CO 2 capture and photocatalytic reduction

Abstract: Hierarchical heterostructure photocatalysts with broad spectrum solar light utilization, particularly in the near-infrared (NIR) region, are emerging classes of advanced photocatalytic materials for solar-driven CO2 conversion into value-added chemical feedstocks. Herein, a novel two-demensional/three-demensional (2D/3D) hierarchical composite is hydrothermally synthesized by assembling vertically-aligned ZnIn2S4 (ZIS) nanowall arrays on nitrogen-doped graphene foams (NGF). The prepared ZIS/NGF composite shows enhancement in photothermal conversion ability and selective CO2 capture as well as solar-driven CO2 photoreduction. At 273 K and 1 atm , the ZIS/NGF composite with 1.0 wt% NGF achieves a comparably high CO2-to-N2 selectivity of 30.1, with an isosteric heat of CO2 adsorption of 48.2 kJ mol−1 . And in the absence of cocatalysts and sacrificial agents, the ZIS/NGF composite with cyclability converts CO2 into CH4, CO and CH3OH under simulated solar light illumination, with the respective evolution rates about 9.1, 3.5, and 5.9 times higher than that of the pristine ZIS. In-depth analysis using in-situ irradiated X-ray photoelectron spectroscopy (ISI-XPS) in conjunction with Kelvin probe measurements reveals the underlying charge transfer pathway and process from ZIS to NGF.
