Particle Size and Pore Size Selection on Ordered Mesoporous Silica [PDF]

open access: yes, 2023
Controlling both particle size and pore size is critical when using mesoporous silica for fundamental studies. Pore size can be adjusted by modifying the reaction conditions during synthesis, but achieving a narrow particle size selection can be ...

Preferential attachment of Escherichia coli to different particle size fractions of an agricultural grassland soil. [PDF]

open access: yes, 2007
This study reports on the attachment preference of a faecally derived bacterium, Escherichia coli, to soil particles of defined size fractions. In a batch sorption experiment using a clay loam soil it was found that 35% of introduced E.

Impact of different particle size distributions on anaerobic digestion of the organic fraction of municipal solid waste [PDF]

open access: yes, 2013
Particle size may significantly affect the speed and stability of anaerobic digestion, and matching the choice of particle size reduction equipment to digester type can thus determine the success or failure of the process.

Intrinsic speckle noise in in-line particle holography due to poly-disperse and continuous particle sizes [PDF]

open access: yes, 2000
In-line particle holography is subject to image deterioration due to intrinsic speckle noise. The resulting reduction in the signal to noise ratio (SNR) of the replayed image can become critical for applications such as holographic particle velocimetry ...

Size Effects in the Particle-Reinforced Metal-Matrix Composites [PDF]

open access: yes, 2002
Many experimental observations have shown the influences of particle size on the mechanical properties of the particle-reinforced metal-matrix composite. However. the conventional theory cannot explain the phenomena because no length scale parameters are

Effect of Particle Size on Bamboo Particle Board Properties

open access: yesFloresta e Ambiente, 2019
In this work, bamboo chips (Dendrocalamus asper) were crushed according to four particle size classes (A = -35+40 mesh; B = -40+48 mesh; C = -48+60 mesh; D = -60+65 mesh) to produce particleboards with four different compositions (100%A; 75%A + 25% B; 50%
