The electrocatalysts synthesized by this method have well-separated, size-controlled nanoparticles with tunable interparticle distance, and thus enable the examination of the particle proximity effect on the oxygen reduction reaction (ORR). The particle proximity effect proposes that the activity of fuel cell catalysts depends on the distance between the catalyst particles and is here for the ...
Tunable interparticle distances allow designer materials with dielectric functions tailorable from that characteristic of an insulator to that of a metal, and serve as strong optical absorbers or scatterers, respectively.

Understanding interparticle interactions in powder systems is crucial to pharmaceutical powder processing. Nevertheless, there remains a great challenge in identifying the key factors affecting interparticle interactions. Factors affecting interparticle interactions can be classified in three differ …
The paper deals with the potential use of these active substances to reveal interparticle contact force networks in granular media under mechanical loading. Preliminary uniaxial tensile tests were first performed on two types of longitudinal specimens for comparison purposes: pure epoxy resin and epoxy resin containing mechanoluminescent powders.

Jan 20, 2022Seven porosity types (interparticle, intraparticle, intercrystal, moldic, fenestral, fracture, and vugs) are common and volumetrically important. Although fracture porosity is very common in carbonate rocks, it is generally less than 1% of the bulk volume in both clastic and carbonate reservoirs. Influence of textural parameters on porosity
A series of highly efficient amine functionalized SiO 2 -TiO 2 supported bimetallic PdCu catalysts with varied metal composition have been synthesized. Ethane-1,2-diamine, butane-1,4-diamine and hexane-1,6-diamine were employed as interparticle linkers for amine functionalization of a SiO 2 -TiO 2 support material so as to study the effect of pendant chain length on stabilization and ...
Ambiguity. From the very general considerations, the mean inter-particle distance is proportional to the size of the per-particle volume /, i.e., / /, where = / is the particle density.However, barring a few simple cases such as the ideal gas model, precise calculations of the proportionality factor are impossible analytically. Therefore, approximate expressions are often used.
The particle model describes matter in a very specific way. It describes four important aspects of matter: All matter is made up of particles that are incredibly small - much too small to see with the naked eye. The particles can be atoms or combinations of atoms that are bonded. There are forces between the particles.
Interparticle void volumes and porosities of packed capillaries have been determined using intraparticle Donnan exclusion of a small, unretained, co-ionic tracer (nitrate ions). The operational domain of this approach has been characterized for bare silica, reversed-phase, and strong cation-exchange …
The architecture of nanoparticle assemblies can be controlled by employing of AuNP with various size, shape [1, 13], and by modification of the interparticle spacing. This distance can be changed by selecting of appropriate cross-linking agent, for instance alkyldithiol- [ 2, 3, 4 ] or thiol-terminated molecules with specific functional properties [ 9, 10 ].

The degree of interparticle interactions between the components of binary powder systems was assessed using surface energy heterogeneity characterization performed in the IGC set-up. Three different scenarios comprising of structured, random and segregated binary powder systems of D-Mannitol and glass beads were hypothesized for the analysis in the IGC column.

In physics, the thermal de Broglie wavelength (, sometimes also denoted by ) is roughly the average de Broglie wavelength of particles in an ideal gas at the specified temperature. We can take the average interparticle spacing in the gas to be approximately (V/N)1/3 where V is the volume and N is the number of particles.
