Supercritical multicomponent solvent coal extraction [PDF]
, 1983 The yield of organic extract from the supercritical extraction of coal with larger diameter organic solvents such as toluene is increased by use of a minor amount of from 0.1 to 10% by weight of a second solvent such as methanol having a molecular ...

Dimensionless scaling of heat-release-induced planar shock waves in near-critical CO2
, 2017 We performed highly resolved one-dimensional fully compressible Navier-Stokes simulations of heat-release-induced compression waves in near-critical CO2. The computational setup, inspired by the experimental setup of Miura et al., Phys. Rev.

Advanced Materials Technologies, EarlyView.Volumetric additive manufacturing allows to print parts extremely fast, but is so far is limited by the build volume of the printers. The foaming materials presented here allow to expand printed parts up to 500% reaching densities of 0.16 g cm−3 as well as providing shape memory properties enabling the creation of lightweight, functional parts ...

Transcritical rotating flow over topography [PDF]
, 2007 The flow of a one-and-a-half layer fluid over a three-dimensional obstacle of non-dimensional height M, relative to the lower layer depth, is investigated in the presence of rotation, the magnitude of which is measured by a non-dimensional parameter B ...

Advanced Optical Materials, EarlyView.This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Soft-wall induced structure and dynamics of partially confined supercritical fluids
, 2019 The interplay between the structure and dynamics of partially confined Lennard Jones (LJ) fluids, deep into the supercritical phase, is studied over a wide range of densities in the context of the Frenkel line (FL), which separates rigid liquidlike and ...

Onset of convection in a finite two-dimensional container due to unipolar injection of ions [PDF]
, 2013 This work addresses the stability of a two-dimensional plane layer of a dielectric liquid enclosed in wall bounded cavities of different aspect ratios and subjected to unipolar injection of ions. Numerical simulations have been conducted to investigate

Graded Plasmonic Metagratings for Directional Nonlinear Optical Sensing
Advanced Optical Materials, EarlyView.A refractometric sensing approach is presented, based on the angular variation of the emission pattern while changing the local environment. This method is first demonstrated on rectangular arrays, then on an aperiodic metagrating configuration designed to shape the first diffraction orders into a broadened band. Abstract Plasmon‐enhanced sensing based
