We also point out reference =-=[19]-=-, where it was also argued that a thin spherical shell held in mechanical and thermodynamic equilibrium at its horizon would have entropy SBH = A/4. It is necessary a priori to distinguish between the......
In spite of what the calculations show, this fact is difficult to either visualize or comprehend, compared to 1 g of iron as one spherical particle, which has a diameter of 6.25 mm and a surface area of 127.8 mm2, or a square with sides measuring 11.3 mm only. In a typical D90 10 ...
particle to be of certain geometry. Usually a known geometry such as a sphere or ellipse is used to represent the object and the equivalent surface area is calculated. Modified GSA is the area represented by a closed, hollow, polyhedron constructed by a thin shell of scale-specific triangles....
which are driven by the thin-film transistors (TFT) underneath. The manufacturing of display panels thus relies critically on the integration of large-scale perovskite micro-arrays and TFT panels. Currently, most PeLEDs are fabricated by solution-processed methods...
We present an engineered nanolattice material with enhanced mechanical properties that can be broadly applied as a thin film over large areas. The nanolattice films consist of ordered, three-dimensional architecture with thin-shell tubular elements, resulting in favorable modulus-density scaling (n ~...
For simple s–p bonded metals, e.g., Li, Na, K, Mg, Al, such interatomic potentials can be derived rigorously from the electrostatics of interacting spherical screening clouds of electrons called pseudo-potentials. The presence of d-electrons at or near the Fermi level spoils this simple ...

Reducing CO2 emissions is an urgent requirement at present. Instead of the incineration and the landfill treatment, the conversion of biomass and plastic w
With such a wide variety of items, there's bound to be something for everyone this weekend. It’s a great way to find unique treasures and maybe some hidden gems. Don't forget to bring cash, plenty of bags, and a friend to help negotiate those bargains. Happy treasure hunting!
