On the Effect of Creep on Local Lattice Orientation in Single‐Crystal Ni‐Based Superalloy Microstructures

Advanced Engineering Materials, EarlyView.
During creep of a single‐crystal Ni‐based superalloy, the overall crystal orientation is observed to remain constant while the microstructure evolves. Despite the lack of macroscopic rotation, small (<1°) rotations are observed on the submicron size scale and are accommodated by counteracting rotations over the scale of several micrometers.

Fabrication and In Vitro Characterization of Bioactive Glass/Nano Hydroxyapatite Reinforced Electrospun Poly(ε-Caprolactone) Composite Membranes for Guided Tissue Regeneration

Bioengineering, 2018
Background: Current resorbable and non-resorbable membranes act as a physical barrier to avoid connective and epithelial tissue downgrowth into the defect, favoring the regeneration of periodontal tissues.

Measurement of the charge asymmetry in $B^{\pm}\to ? K^{\pm}$ and search for $B^{\pm}\to ? p^{\pm}$ decays

Phys. Lett., 2014
The CP violating charge asymmetry in B±??K±B±??K± decays is measured in a sample of pp collisions at 7 TeV centre of mass energy corresponding to an integrated luminosity of 1.0 fb-1 collected by the LHCb experiment. The result is CP(B±??K±)=0.022±0.021±0.009ACP(B±??K±)=0.022±0.021±0.009 where the first uncertainty is statistical and the second ...

Nanoengineering the antibacterial activity of biosynthesized nanoparticles of TiO2, Ag and Au and their nanohybrids with Portobello mushroom spores (PMS) (TiOx/PMS, Ag/PMS and Au/PMS) and making them optically self-indicating

, 2016
Results show that nanoparticles (NPs) can be biosynthesized at room temperature on the reductive and chelating surfaces of Portobello mushroom spores (PMS). Using this green approach TiOx, Ag, Au, Ag-TiOx and Au-TiOx NPs have been prepared.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Crystal Growth Engineering for Dendrite‐Free Zinc Metal Plating

Advanced Materials, EarlyView.
This research employed the rare‐earth ion dysprosium (Dy) to modulate aqueous zinc (Zn) metal plating. Integrated multiscale experiments and computational modeling unveiled the preferential adsorption of Dy on specific crystal facets, which activated screw dislocation‐driven Zn growth.
