Summary: Due to the environmental and health hazards caused by traditional food packaging materials, paper-based packaging materials have become increasingly popular. This study focused on the fabrication of fluorine-free degradable water- and oil-repellent paper using low-cost bio-based polymers. The coatings made of carboxymethyl cellulose (CMC), collagen fiber (CF), and modified polyvinyl alcohol (MPVA) provided excellent water and oil repellency to the paper. The resulting paper showed excellent water repellency, oil repellency, low air permeability, and strong mechanical properties, making it suitable for food packaging applications.

Summary: In 1948, Cassie proposed an equation for the wetting of a smooth, heterogeneous surface. This equation uses weighted averages based on the fractional surface areas and cosines of contact angles to predict the contact angle of a droplet on a composite surface. The equation has proven fundamental in understanding the wetting of superhydrophobic and superoleophobic surfaces. However, little attention has been given to the complete wetting of one surface component.

Summary: A high-performance superhydrophobic stainless steel mesh membrane with a hairy-like poly(divinylbenzene) coating has been fabricated using a facile synthesis method. The unique hair-like microstructure of PDVB is responsible for the superhydrophobic performance with less blockage for the pores, achieving higher efficiency in separating oil/water mixtures. The mesh displays an unprecedentedly high intrusion pressure while maintaining a high flux, enabling further increment of flux under reduced pressure.

Summary: As research on superhydrophobic materials inspired by nature continues, the preparation methods and applications of superhydrophobic surfaces made from silicone substrates are widely reported. Silicones are preferred due to their inherent hydrophobicity and processing ability. Despite the low mechanical stability, it can be improved through rational design. This review provides an overview of silicone-based superhydrophobic surfaces and their applications, serving as inspiration for polymer interfaces and colloid science development.

Summary: A versatile method is developed to enhance the protective efficacy of silane-based materials against rainwater and organic pollutants by tuning their wetting properties. This is achieved through blending a commercially available silane product with a fluoropolymer and silica nanoparticles to modify the surface morphologies of the coatings. The synergistic effect of surface structure and chemistry leads to the production of superamphiphobic coatings.

Summary: The study aimed to characterize the limestone used in the ancient city of Pella in Macedonia, Greece, revealing variability in stone nature and deterioration within monuments due to factors like water absorption and biological colonization. Through microanalysis and testing, the mineralogical, chemical, mechanical, and thermal properties of the stones were fully characterized. Results showed the dominance of calcite as the main mineral phase, with traces of quartz and clay minerals detected. Thermographical measurements indicated limited decay due to ambient temperature variation, while high porosity and low compressive strength suggest vulnerability of the stone and necessity for conservation measures.

Summary: High Performance Liquid Chromatography coupled to a Diode-Array-Detector (HPLC-DAD) was used to analyze samples from ancient Egyptian textiles, identifying components such as purpurin and indigoid dyes. The results suggest that the composition of madder dye used in these samples may vary depending on the plant source, with a possible use of Rubia tinctorum or other Rubiaceae family plants.
