The sheet height, lateral size, number of layers, and presence of the oxygen functional group in graphene oxide (GO) intended for certified reference material (CRM) samples were obtained using advanced techniques for physicochemical and dimensional analysis.

This multi-technique archaeometric study of Bitoca I ceramic fragments reveals sophisticated Pre-Columbian production methods employing local clays with quartz/feldspar and plant temper (cariapé), fired at ≤ 850 °C. Analytical data confirm both culinary use (Ca-P-Mg residues) and deliberate material selection, demonstrating advanced technological knowledge. The coexistence of different tempers highlights the diversity of Amazonian ceramic traditions and provides new insights into regional socio-technical practices.

A sample preparation protocol for scanning electron microscopy (SEM) analysis of nanostructured biomaterials with L929 cells was optimized, enabling satisfactory visualization of cell morphology and adhesion.

In this research, a TiO₂ film matrix was prepared, and the effects of an alkali metal doping process (K, Rb, and Cs) were evaluated by monitoring its morphological, electrical, and structural evolution. The aim was to facilitate green hydrogen production and solar energy conversion.

Microwave-assisted hydrothermal synthesis of TiO₂ nanoparticles using titanium(IV) isopropoxide (TIP) and tetramethylammonium hydroxide (TMAH) yields anatase-phase nanostructures. One- and two-step heating produced particles with different morphologies and surface areas. Both samples demonstrated high photocatalytic efficiency in degrading rhodamine B under ultraviolet-visible (UV) light.

Electrospun polyamide 6 (PA-6) nanofibers loaded with methylene blue for topical photodynamic therapy.

Different exfoliation methods were applied to obtain reduced graphene oxide (rGO) with varied lateral sizes. Photothermal studies under near-infrared (NIR) irradiation showed efficient heat generation. Sheet size had minimal influence on the photothermal performance.

The evolution of open circuit potential (OCP) over time was monitored to evaluate corrosion resistance of aluminium alloys. Localized attack occurred even at more noble potentials. This highlights the limitations of using OCP as a standalone technique for corrosion resistance assessment.

The graphical abstract illustrates the use of scanning electron microscopy (SEM) to investigate oil well cement microstructures. Representative SEM images reveal hydration products, carbonation phases, and morphological changes under various conditions.

The Graphical Abstract consists of three scanning electron microscopies obtained in the analysis of TiO₂ nanotubes synthesized in the presence and absence of iron ions.

Two solvent compositions (70 and 90% ethanol, v/v in water) and varying sonication times (0-2 h) were evaluated to investigate their effects on lignin nanoparticle formation, morphology, and size.
