Matrix metalloproteases are key regulatory molecules in the breakdown of extracellular matrix and in inflammatory processes. Matrix metalloproteinase-1 (MMP-1) can significantly enhance muscle regeneration by promoting the formation of myofibers and degenerating the fibrous tissue. Herein, we prepared novel MMP-1-load…

Aberration corrected HRTEM has been successfully applied to image the atomic motion at the edges and surfaces of nanoparticles of ceria of various types under electron irradiation. Here we identify movements not only on {100} facets, but also on {110} and even {111} facets, previously considered stable. However, the d…

We present a morphology study of ZnO tetrapods using aberration corrected TEM, HAADF-STEM and 3D HAADF-STEM cryotomography as an alternative to more conventional TEM and SEM techniques. We use 3D IMOD reconstructions to show that the {1 0} facets dominate the total surface area of uniform hexagonal prism tetrapods. Us…

Electrospun materials have been proposed for application for gas filtration, drug carriers, and tissue engineering. The surface morphology of electrospun fibers is the key for consideration for the above applications, such as pore size on the fiber surface, surface area, and roughness. In this work, we investigated th…

Dielectric property of epitaxial SrBi4Ti4O15 thin films with (001)-, (1110)-, (105)/(015)-, and (100)/(010)-orientations was investigated as a function of film thickness. As the tilting angle of c-axis from the surface normal is smaller, the relative dielectric constant begins to degrade at thinner thickness; eventual…

Abstract A comprehensive theoretical study of electronic transitions of naphtho‐homologated yyG and its five possible tautomers (yyG‐AO7, yyG‐AEc, yyG‐AEt, yyG‐IcO17, and yyG‐ItO17) was performed. The nature of the low‐lying excited states is discussed, and the results are compared to that of y‐bases. Geometry optimiz…

The shoes are important for the skin of our feet. It is protecting feet from injurious things in the ground. Some of the dermatoses of the feet are greatly affected by the type of the shoes a patient is wearing. However, little attention is made on the value and functions of the shoes and its impact on our skin. This…

In this study, an optically active biodegradable poly(urethane-imide) (PUI) derived from L-tyrosine was synthesized. Since biopolyurethanes cannot be fully competitive with conventional thermoplastics and are sometimes too weak for practical use, these biopolymers have been formulated and associated with nano-sized fi…

We identified magnetoelectric effect in an ultrathin (Cr2O3/Fe2O3) nano-oxide layer structure (thickness ∼1 nm) formed on the surface of a Co0.9Fe0.1 metal layer by investigating the training effect as a function of sense current/bias voltage and its direction. A system-dependent constant κMR, which reflects changes i…

Prediction of structural dynamics of the Electric Arc Furnace (EAF) is rather difficult, because of a number of phenomena occurring during the scrap melting process. Three large electrodes, corresponding to each phase of a AC circuit, are lowered by the main mast towards the scrap to activate the melting process, indu…

Transmission electron microscopy and diffraction are used to measure the lattice strain in catalytic Au-Pd core-shell nanoparticles. In order to simplify analysis, single nanoparticles were oriented to achieve strong two-beam diffracting conditions from the nanoparticle centre, such that diffraction was sensitive to t…

We point out that a system which supports chiral superconductivity should also support a chiral pseudogap phase: a finite temperature phase wherein superconductivity is lost but time-reversal symmetry is still broken. This chiral pseudogap phase can be viewed as a state with phase incoherent Cooper pairs of a definite…
