Multi-physics modeling of heat and particle transfer in porous media
… dissipation considering the convection heat transfer in porous media and the filtration mechanisms of bentonite grout in porous media. In the first part, the study challenges traditional underground duct-bank design assumptions and introduces a novel approach to enhance heat dissipation …

Gas-Phase Covalent And Non-Covalent Ion/ion Chemistry Of Biological Macromolecules
… spectrometer. During this gas-phase chemistry, particle transfer (i.e., proton and electron) or synthesis can occur at rapid reaction rates. Particle transfer represents a mature area of ion/ion chemistry, while selective covalent modification represents a fairly new area of gas-phase chemistry. …

Advanced Optimization Techniques For Monte Carlo Simulation On Graphics Processing Units
… for a relatively small size problem of 4096 particles. In addition, two algorithms to run on the GPU with and without cell list structure have been implemented. The total speedup of the parallel code with cell list over the serial code was more than 160x faster. Moreover, for the grand …

The ⁴⁴Ca(d,α)⁴²K reaction at 4.0 MeV
… useful tool in understanding single- and two-particle transfer reactions and nuclear structure. The 4 MV Van de Graaff accelerator at Virginia Polytechnic Institute and State University was used to check the feasibility of DWBA analysis on the (d, α) reaction at low bombarding energies for …

ELASTIC SCATTERING AT RELATIVISTIC ENERGIES OF ALPHA PARTICLES AND PIONS BY NUCLEI USING AN OPTICAL POTENTIAL
… energies. This code was used to analyze alpha particle and pion scattering at relativistic energies upon different target nuclei and to find a relativistic potential for a system at a given energy. The target particles in the alpha study were 12C, 40,42,44,48Ca and other alphas. The pions were …

Investigating the pH of atmospheric fine particles and implications for atmospheric chemistry
Particle acidity is a critical but poorly understood quantity that affects many aerosol processes and properties, including aerosol composition and toxicity. In this study, particle pH and water (which affects pH) are predicted using a thermodynamic model and measurements of RH, T, and inorganic …

Effect of Chemistry on Electrodynamics in the Martian Dynamo Region
… transition and subsequent trans-terminator particle transfer. The time scales of atmospheric collisions, gyromotions, and chemical processes are discussed in detail to support the selection of relevant reactions for mesoscale studies of the dynamo regions. Several schemes are available in …

High-Throughput Determination of Mycobacterium smegmatis Protein Complex Structures
… was tested to find the optimal grid property for particle transfer. This established that particles of GroEL could be transferred from BN-PAGE onto an EM copper grid and a successful negative stain reconstruction was obtained. In summary, the pipeline from purifying protein complexes to generating …
