Designing rigid carbon foams.
We use ab initio density functional calculations to study the stability, elastic properties and electronic structure of sp(2) carbon minimal surfaces with negative Gaussian curvature, called schwarzites. We focus on two systems with cubic unit cells containing 152 and 200 carbon atoms, which are metallic and very rigid. The porous schwarzite structure allows for efficient and reversible doping ...
متن کاملSome problems in water vapor tomography
The technical success and availability of numerical algorithms have promoted the implementation of tomography to atmospheric sciences. The principal specific character in initial constraints, data collection and assimilation methods, obtaining the final numerical results and interpretation of these makes the continuation of success story for GPS-tomography very challenging. The authors use nume...
متن کاملRelationships between macroscopic paper structure and water absorption behavior
Macroscopic structure of paper influences how paper behaves in many ways. In this research, the relationship between macroscopic paper structure and water absorption behavior was investigated. The structure of the handsheets made from commercial hardwood pulp was modified by varying basis weight, beating levels and wet press levels. The structural properties as well as the water absorption prop...
متن کاملRelationship between Atmospheric Water Vapor Transfer and Daily Rainfall in Iran
Introduction Because the occurrence of precipitation is directly related to the humidity in the atmosphere or precipitation systems, the study of humidity in the form of precipitable water and the transfer of water vapor is considered in atmospheric studies. Convergence Moisture flux is effective on precipitation, so its effect is much greater in the warmer months, especially in the lower at...
متن کاملmodeling water vapor sorption and permeability in starch-montmorillonite nanocomposite films
the aim of this study was to investigate the rate of water vapor permeability (wvp) and moisture sorption of starch-montmorillonite (mmt) nanocomposite films. the nanocomposite films were prepared using the casting method andglycerol was used as a plasticizer. the effect of glycerol concentration on wvp of the films was determined at 25°c with a relative humidity of 0-99% (inside and outside of...
