Abstract Cerium oxide nanoparticles (CeO2 NPs) have shown a potential capacity to destroy organic dyes because of their ability to generate reactive oxygen species (ROS) in aqueous phase. The photodegradation process can be influenced by the superficial area of the nanoparticle and the pH of the solution. This work studied the photocatalytic performance of CeO2 NPs at two sizes, …
The effect of pH, particle size and crystal form on dissolution behaviour of zinc metal, ZnO and TiO2 was investigated using a simple 2 h solubility assay at body temperature (37 °C) and two pH conditions (1.5 and 7) to approximately frame the pH range found in human body fluids.
Particle size may vary with pH as a result of a change in zeta potential (or effective net charge) of the particles in aqueous suspension under the specific solution conditions. Near the ...
The present study was performed in two parts to evaluate the effect of pH value and bismuth oxide particle size on the DTS of WMTA cement. pH Value Thirty cylindrical moulds (Scientific Labware Glass, China) with a 4mm diameter and 6 mm height were provided and divided into six groups of five in each (n=5).
The impact of particle size and pH on bovine serum albumin (BSA) corona formation of solid lipid nanoparticles (SLNs) was studied here. The BSA corona formation of SLNs with increasing particle size (120-480 nm) in pH 6.0 and 7.4 was investigated.

At optimum pH, solution supersaturates and due to generation of large nucleation centers particle size decreases. Therefore to synthesize the particles in the nanoscale dimensions, it is suggested that chemical reaction should be carried out at an optimum pH value of precursor solution.
At pH = 2, a low particle agglomeration rate is achieved, while a high agglomeration rate (large particle agglomerate size) is obtained for NPSs at pH = 6, for all the NPSs types. The reason for this is because the pH iso of TiO 2 particle is in the range of 5–7, and the NPSs at or near this range exhibit unstable behaviour [27] .
The relation between PH and the size of nano-particles is reversible, when PH (increases from 8 to 14) the size of nanoparticles should be reduced (decreased), and vice versa for PH …

When pH of the precursor solutions increased, the size of CaCO 3 particles synthesized using [1]:[2] [Ca 2+]:[CO 3 2−] ratio constantly increased, reaching 4.09 ± 0.87 μm at pH 13.0. The increase in CaCO 3 particle size with an increase in precursor solution pH was independent from the [Ca 2+]:[CO 3 2−] ratios used in this study, offering ...
