© 2020 Elsevier B.V. Molybdenum sulfide (MoS2) with layered structure has emerged as a promising anode material for sodium ion batteries (SIBs) in light of its particular surface chemistry and physical structures. However, the MoS2-based SIBs usually suffered from the weaknesses of the low rate capability and poor cycling stability induced by the sluggish kinetics of Na+ intercalation and the diffluent discharge products. Herein, the defective MoS2 nanocrystals and sulfur nanodots simultaneously embedded in sulfurized polyacrylonitrile (SPAN) fibers were fabricated via an electrospunning technology, followed by a simple annealing treatment. The unique architecture, in which MoS2 nanolayers and sulfur nanodots …

Quantitative ultrasound has a great potential for the non-destructive evaluation of tissue engineered constructs, where the local attenuation and the integrated backscatter coefficient (IBC) can be used for monitoring the development of biological processes. The local determination of both parameters can be achieved using the reference phantom method (RPM). However, its accuracy can be affected when evaluating constructs of evolving sound speed, attenuation and thickness, for example, when evaluating biodegradable hydrogels developing neocartilage. To assess the feasibility of using the RPM under such dynamic conditions while employing a 50-MHz transducer, we conducted a series of experiments on 3-mm-thick acellular hydrogels …
