  1. Vor 4 Tagen · The Leidenfrost effect—the levitation and hovering of liquid droplets on hot solid surfaces—generally requires a sufficiently high substrate temperature to activate liquid vaporization. Here ...

  2. Vor 5 Tagen · Armed with the unequivocal results of Hahn and Strassmann, however, Meitner and Frisch invoked the recently formulated liquid-drop model of the nucleus to give a qualitative theoretical interpretation of the fission process and called attention to the large energy release that should accompany it. There was almost immediate ...

  3. Vor 2 Tagen · π–π stacking are omnipresent interactions, crucial in many areas of chemistry, and often studied using quantum chemical methods. Here, we report a simple and computationally efficient method of estimating the binding energies of stacked polycyclic aromatic hydrocarbons based on steered molecular dynamics. This method leverages the force field parameters for accurate calculation. The ...

  4. Vor 3 Tagen · The ANN model used in the study to deconvolve the neutron energy spectra consisted of an input layer, two hidden layers, and an output layer. In the first hidden layer, there are 144 neurons, and in the second hidden layer, nine or more neurons were used because they can achieve the desired and very accurate result. The high number of neurons ...

  5. Vor 4 Tagen · To understand the energetics of such systems, Sarah Loos of the University of Cambridge and colleagues have studied a simple model of microscale transport. They used optical tweezers—a laser beam that can trap a small particle—to drag a 2.7-micrometer-diameter silica sphere through fluids. “This problem is simple enough to be solved analytically and realized experimentally, yet rich ...

  6. Vor 2 Tagen · Semi-empirical mass formula which gives expression for binding energy. The semi-empirical mass formula for the liquid drop model is given by: \ [ { {E}_ {B}}= { {a}_ {v}}A- { {a}_ {S}} { {A}^ {\dfrac {2} {3}}}- { {a}_ {c}}\dfrac {Z (Z-1)} { { {A}^ {\dfrac {1} {3}}}}- { {a}_ {a}}\dfrac { { { (A-2Z)}^ {2}}} {A}+\partial (A,Z)\]
