Electrocoagulation of whey acids: anode and cathode materials, electroactive area and polarization curves

Journal of Electrochemical Science and Engineering, 2017
Anode (Al and Fe) and cathode (graphite and Ti/RuO2) materials have been tested for electrocoagulation (EC) and purification of the acid whey. The electroactive areas (EA) of electrodes were calculated by the double layer capacitance method.

Microeukaryotic Diversity and Habitat Structuring in a Desiccating Alkaline Maar Lake (Central Mexico)

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Microeukaryotes are important components of microbial food webs in saline and alkaline lakes, yet their diversity and distribution across distinct microhabitats remain poorly understood. We characterized microeukaryotic communities associated with microbialites, microbial mats, hypersaline waters, and sediments in the desiccating maar lake ...

Crystal structure of 2-(2-aminophenyl)-1,3-benzoxazole

Acta Crystallographica Section E: Crystallographic Communications, 2015
Crystals of the title compound, C13H10N2O, were grown from a dichloromethane/ketone/methanol solvent mixture. It crystallizes with two molecules, A and B, in the asymmetric unit with very similar almost planar conformations [dihedral angles between the ...

Effect of Eu3+ Addition on the Structural, Morphological, and Luminescent Properties of Hydroxyapatite Nanostructures Synthesized by Microwave‐Assisted Hydrothermal Method

Crystal Research and Technology, Volume 61, Issue 10, October 2026.
Eu‐containing hydroxyapatite nanostructures are synthesized by a microwave‐assisted hydrothermal route using glutamic acid. Eu addition preserves the hexagonal apatite phase while progressively modifying fiber morphology and generating characteristic red emission from low‐symmetry Eu3+ environments.

Surface Properties, Color Stability, and Bacterial Adhesion of Implant‐Supported Provisional Restorative Materials: In Vitro Study

Clinical and Experimental Dental Research, Volume 12, Issue 5, October 2026.
Abstract Objectives To evaluate surface roughness, wettability, color stability, and bacterial adhesion of different materials used in implant‐supported provisional restorations. Materials and Methods Eighty samples (6 × 6 × 2 mm ± 0.2 mm) were fabricated and distributed into four groups (n = 20): Bis‐acryl composite resin (BCR); CAD‐CAM PMMA resin ...
