Summary: By modifying the surface of CdS nanorods with Ag2S nanodots, the CO2 reduction activity was enhanced, achieving a high CO partial current density of 10.6 mA cm(-2), demonstrating the effectiveness of the cooperative catalyst with a fast CO2 reduction rate and 95% Faradaic efficiency for C-1 products at a current density of 200 mA cm(-2) when using a flow cell.

Summary: This study combines NMR relaxometry and rheology to investigate the structure and behavior of egg-tempera painting, shedding new light on its physicochemical properties. By reproducing model formulations from the 15th century, it was found that there is a synergistic effect between green earth and egg yolk in the paint. The presence and structure of a network formed by the yolk and the pigment were emphasized by H-1 NMR relaxometry.

Summary: This study provides insights into the causes and mechanisms of darkening of fake-gilded decorations in tempera paintings, emphasizing that Ag-0 and moisture are key factors triggering the transformation of As2S3 to alpha-Ag2S and As-oxides. The high specificity, sensitivity, and lateral resolution of the analytical methods used in the research allowed for the identification of black acanthite, mimetite, and syngenite as degradation products in Cimabue's Maesta painting.

Summary: Oleogels were prepared using egg-white protein microgel as a gelator and xanthan gum (XG) as a thickener. The properties of the emulsion and oleogels were investigated. The studies showed that a concentration of 2% of protein microgel resulted in the saturation of protein adsorption on the surface of oil droplets. Excess protein combined with XG and accumulated on the outer layer of the oleogel, preventing flocculation and enhancing the oil-holding capacity. Furthermore, XG concentration affected the viscosity and mechanical properties of the emulsion, but had no significant effect on oil oxidation.

Summary: In the 15th century, the use of oil paint gradually replaced egg yolk as a binder in tempera painting, leading to a major change in painting technique in Europe. A mixed technique called tempera grassa, which combines egg and oil as emulsion, was occasionally used during this transitional period. This article investigates the physico-chemical aspects of emulsion-based binders, prepared with egg yolk and either raw linseed oil or lead-treated linseed oil, to better understand this historical painting practice.

Summary: Structured emulsions were designed through complexation between FEWP and pectin, affecting properties such as pH, protein-to-pectin ratio, and biopolymer concentration. Pectin significantly improved the viscosity and elastic modulus of emulsions prepared by FEWP, with the effect optimized at a protein-to-pectin ratio of 10:1 and pH 3.7.

Summary: In this work, a dual metal-substituted MOF material with high surface area and large pore volume was synthesized. It showed specific redox activity under visible light and the combination with CdS significantly improved charge separation efficiency. This study provides a new insight that Ti substitution benefits the performance of Ce-based MOF.

Summary: This study revealed that under the presence of sodium hexametaphosphate (SHMP), nanofibrillated egg white proteins (EWP) could form a well crosslinked network in emulsions, leading to improved creaming stability and rheological properties. This enabled the fabrication of reduced-fat emulsions with a similar or stronger texture than high-fat emulsions, providing insight into designing structured acidic oil-in-water emulsions using nanofibrillated EWP crosslinked by SHMP.

Summary: In this study, high-intensity ultrasound and heat treatment were utilized to improve the properties of egg white peptides and enhance the stability of emulsions. The treatment resulted in depolymerization of peptides, smaller particle size, increased surface charges, and improved interfacial activity. The treated peptides showed enhanced antioxidant activity, altered secondary structure, better dispersion and lower viscosity of emulsions, as well as improved stability and reduced oxidation.

Summary: Biomineralization is an important process utilized by microorganisms to sequester heavy metal ions, with this study showing the significant improvement of cadmium resistance and removal abilities in a deep-sea bacterium through CdS nanoparticle biomineralization using L-cysteine. The psTD enzyme was identified as a key factor in enhancing bacterial cadmium resistance and directing the formation of CdS nanoparticles. Results also showed the development of single-enzyme biomineralization of CdS nanoparticles driven by psTD, indicating its potential as a capping reagent for controlling the size and structure of nanocrystals.

Summary: This study investigated the effects of different concentrations of gellan gum (GG) with/without basil essential oil (BEO) on the physicochemical properties of gellan gum-rice bran oil (GG-RBO) emulsions. The results showed that GG-RBO emulsions with higher concentrations of GG were more stable and had better coating performances. The addition of BEO further improved their stability and coating performances, making them effective for egg preservation.

Summary: This study focused on the suitability of urea-aldehyde resin Laropal (R) A81 for consolidation treatments on deteriorated wood from panel paintings. Results showed that Laropal (R) A81 has good specificities for wood consolidation, with effective penetration and retention depth. Comparison with other resins and various tests supported the use of Laropal (R) A81 as a consolidant for deteriorated wood in easel paintings.
