Abundant interaction solutions of the KP equation

Abstract: Based on the Hirota bilinear form of the KP equation, five classes of interaction solutions between lumps and line solitons are generated via Maple symbolic computations. Analyticity is automatically guaranteed for the first four classes of interaction solutions and the last fifth class of interaction solutions with the plus sign and can be easily achieved for the last fifth class of interaction solutions with the minus sign by taking special choices of the involved parameters. The presented interaction solutions reduce to the existing lumps while the hyperbolic function disappears.

Ultrathin Two-Dimensional Nanostructures: Surface Defects for Morphology-Driven Enhanced Semiconductor SERS.

Abstract: Two-dimensional (2D) semiconductors have recently become attractive candidate substrates for surface-enhanced Raman spectroscopy, exhibiting good semiconductor-based SERS sensing for a wider variety of application scenarios. However, the underlying mechanism remains unclear. Herein, we propose that surface defects play a vital role in the magnification of the SERS performances of 2D semiconductors. As a prototype material, ultrathin WO3 nanosheets is used to demonstrate that surface defect sites and the resulting increased charge-carrier density can induce strong charge-transfer interactions at the substrate-molecule interface, thereby improving the sensitivity of the SERS substrate by 100 times with high reproducibility. Further work with other metal oxides suggests the reduced dimension of 2D materials can be advantageous in promoting SERS sensing for multiple probe molecules.

Properties of failure mode and thermal damage for limestone at high temperature

Abstract: The mechanical properties of limestone such as the stress-strain curve, the variable characteristics of peak strength and the modulus of elasticity of limestone were studied under the action of temperatures ranging from room temperature to 800 °C. Our results show that: 1) the temperature has not clear effect on the mechanical properties of limestone from room temperature to 600 °C. However, the mechanical properties of limestone deteriorate rapidly when the temperature is above 600 °C. In this case, the peak stress and modulus of elasticity decrease rapidly. When the temperature reaches 800 °C, the entire process, showing the stress-strain curve is displayed indicating an obvious state of plastic-deformation; 2) the failure mode of limestone shows the breakdown of tensile strength from room temperature to 600 °C, as well as the compress shearing damage over 600 °C; 3) combining our test results with the concept of thermal damage, a thermal damage equation was derived.
