We introduce a method for the analysis of nucleation using mean first-passage time (MFPT) statistics obtained by molecular dynamics simulation. The method is based on the Becker-Döring model for the dynamics of a nucleation-mediated phase change and rigorously accounts for the system size dependence of first-passage statistics. It is thus suitable for the analysis of systems in which the separa...

Well-controlled and well-characterized experimental measurements are obtained during the melting of a moderate-Prandtl-number material (n-eicosane) in a cylindrical enclosure heated from the side. The study aims to provide benchmark experimental measurements for validation of numerical codes. Experimental results in terms of measured temperatures and melt front locations are reported in both gr...

The conformational states explored by polymers and proteins can be controlled by environmental conditions (e.g., temperature, pressure, and solvent) and molecular chemistry (e.g., molecular weight and side chain identity). We introduce an approach employing the diffusion map nonlinear machine learning technique to recover single molecule free energy landscapes from molecular simulations, quanti...

Background: Plantago lanceolata L. (ribwort plantain) and major (broadleaf are widely used in ethnobotanical studies for treating various diseases. This study aims to investigate the antimicrobial activity chemical compounds of these plants. Methods: The leaf extracts P. were fractioned using different solvents. phytochemical screening was carried out by gas chromatography-mass spectrometry (GC...

Phase change material (PCM) has great potential in thermal control of aircraft electronic components because their excellent latent heat capacity. In the current work, a finned copper foam phase energy storage unit (PCESU) was fabricated using n-eicosane, 97.2% porosity and 0.8 mm fins. The effects four different heating power i.e. 40 W, 45 50 55 W corresponding to flux 0.4 W/cm2, 0.45 0.5 0.55...

Ionic liquids have been objects of extensive research for physical sorption of CO2 and a number of myths have been perpetuated in the literature, for lack of a critical analysis, concerning their potential for CO2 capture. This study carries a critical analysis of a number of widely accepted ideas and others not so well accepted that have been repeatedly expressed in the literature concerning t...
