Effect of Ag and Ni-Doped Cerium Oxide Nanoparticles on the Formation of ROS and Evaluation as an Alternative Physical Sunscreen Material.

CeO nanoparticles (nanoceria) were proposed as an alternative physical sunscreen agent with antioxidant properties and comparable UV absorption performance. Green synthesis of nanoceria with Ag and Ni dopants resulted in doped nanoceria with lower catalytic activity and biologically-safe characteristics. The doped nanoceria was characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), Rancimat Instrument, and UV-Vis Spectrophotometer for SPF (Sun Protection Factor) determination.

A morphological study of bicontinuous concentric lamellar silica synthesized at atmospheric pressure and its application as an internal micro-reflector in dye-sensitized solar cells.

KCC-1, a nanostructured silica material with a bicontinuous concentric lamellar (bcl) morphology, provides plenty of functional characteristics, such as an open channel structure, excellent accessibility, and a large surface area. Although bcl silica exhibits various superior properties, studies on its morphology and its application in dye-sensitized solar cells (DSSCs) are still limited. Therefore, this work aims to study the influence of the synthesis time on the morphology of bcl silica.

Contribution of the lamellar morphology to the photocatalytic activity of alkaline-hydrothermally treated titania in rhodamine B photodegradation.

TiO particles with a specific morphology are essential for their accessibility and photoactivity. The present study shows that NHOH-based alkaline-hydrothermal treatment affects the transformation of their particle morphology. We investigated the effect of NHOH by varying the synthesis route.

Performance of PEDOTOH/PEO-based Supercapacitors in Agarose Gel Electrolyte.

Poly(3,4-ethylenedioxythiophene) (PEDOT) is a prime example of conducting polymer materials for supercapacitor electrodes that offer ease of processability and sophisticated chemical stability during operation and storage in aqueous environments. Yet, continuous improvement of its electrochemical capacitance and stability upon long cycles remains a major interest in the field, such as developing PEDOT-based composites. This work evaluates the electrochemical performances of hydroxymethyl PEDOT (PEDOTOH) coupled with hydrogel additives, namely poly(ethylene oxide) (PEO), poly(acrylic acid) (PAA), and polyethyleneimine (PEI), fabricated via a single-step electrochemical polymerization method in an aqueous solution.

Lead-Free Aurivillius Phase BiLaNbMnO: Structure, Ferroelectric, Magnetic, and Magnetodielectric Effects.

Aurivillius phase BiLaNbMnO, derived from ferroelectric PbBiNbO by simultaneous substitution of the -site and -site cations, was synthesized using a molten-salt method. Here, we discuss the structure-property relationships in detail. X-ray and neutron diffraction show that BiLaNbMnO adopts an 2 orthorhombic crystal structure.
