Summary: The article provides an overview of synthesizing TiO2 nanoparticles with well-defined nonspherical shapes, emphasizing the importance of controlled and reproducible synthesis for producing reference materials with consistent properties. The need for certified materials with specific shapes is highlighted, along with the development of measurement approaches using electron microscopy to accurately determine size and shape distribution for nonspherical particles. Challenges in synthesizing perfectly monodispersed and solvent-free TiO2 nanoparticles of specific shapes are discussed, as well as successful measurement approaches for extracting accurate spatial information from electron micrographs.

Summary: The sintering process of TiO2 nanoparticles with different particle sizes and temperatures was studied using molecular dynamics simulations. It was found that the merge of surface atoms initiates the sintering process when two particles contact, leading to homogeneous merging of the particles. At high temperatures, the heating provides kinetic energy for atom migration, resulting in faster sintering. Additionally, there is a significant difference in sintering speed between 1600 and 1800 K, and smaller temperature changes have a large impact on the sintering rate near the melting point.

Summary: A novel method utilizing colloidal TiO2 nanoparticles and sodium polyacrylate-derived carbon dots (CDs) was developed to enhance the electrochemical performance of supercapacitors. Addition of CDs to TiO2 electrode and KOH electrolyte significantly increased the specific capacitance, leading to a high areal specific capacitance of 2,200 mF cm(-2). The CD-doped supercapacitor showed excellent rate capability and cycling stability, attributed to the strong electronic coupling and favorable interfacial phenomena provided by the CD additives.

Summary: TiO2 (E171) is commonly used as a coloring agent in processed food. Concerns about the potential health effects of TiO2 nanoparticles have led to the need for monitoring the size distribution and cytotoxic properties of TiO2 in commercial food. This study found that the extracted TiO2 from commercial foods had an average particle diameter of 121-143 nm, with a fraction of nanoscale particles ranging from 7.5% to 35.7%. Certain types of food, such as candy and jelly, were found to contain smaller TiO2 particles with a higher fraction of nanoscale particles. Additionally, the study investigated the effect of three organic acids on the physicochemical properties of TiO2, and found that citric acid reduced the size of TiO2 and generated fragmented nanoparticles. The study highlights the importance of fully assessing the potential long-term health effects of altered TiO2 in processed food.

Summary: The study demonstrates that marine phytoplankton are more sensitive to iron content in solid particles, especially ilmenite and hematite which have a positive impact on the growth of diatoms. Diatoms acquire iron from solid particles, with smaller growth responses when physically separated from dust particles. Additionally, diatoms benefit more from mineral dust particles in direct contact with cells.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
