Summary: Paints play a crucial role in protecting and enhancing the appearance of buildings, making repainting a common maintenance action. Limewashes, which have been used since ancient times, are currently of great interest due to their eco-friendly and antiseptic features, as well as their ability to improve materials' water transport performance. Adding linseed oil can enhance the water-repellent properties of limewashes, but improper dosage may affect the drying kinetics of the substrate. This study investigated the effects of limewashes with varying dosages of linseed oil on natural stones, focusing on water and salt transport. The results showed that water absorption by capillarity was reduced in both stones coated with pure limewash and limewash with oil, while the drying rate was slightly accelerated. The impact of the paints on drying and salt damage varied depending on the porosity of the stones.

Summary: This study demonstrates the detection of adulterants in marine oils using Raman and IR spectroscopy. Support vector machines are able to classify the adulterant present, while partial least squares regression can be used to quantify the adulterants. Data fusion improves the detection accuracy for certain adulterants.

Summary: Organic chelating ligands can enhance the drying efficiency of manganese-based driers for tung oil by altering the spatial and electronic properties. The presence of strongly electronegative coordination atoms improves the drying activity of Mn2+. The quantity of these atoms also promotes paint film drying and property improvements.

Summary: Pistacia vera oil is a rich source of unsaturated fatty acids, with composition varying from year to year depending on climate conditions. Analysis of samples from 2017 and 2018 showed that the oil from 2018 had higher quality and nutritional value compared to 2017, possibly due to a slight decrease in temperature and increase in rainfall. The development of chemometric models using GC-MS analysis, FTIR and Raman spectroscopy data can help in assessing the quality of Pistacia vera oils.

Summary: This study focused on the application of vibrational spectroscopic techniques for the analysis of adulterants in peanut oil. The qualitative analysis showed that MCR-ALS accurately identified all adulterants, while the quantitative analysis demonstrated the effectiveness of both MCR-ALS and PLS in quantifying the adulterants, confirming the feasibility of using these methods in peanut oil.

Summary: The adhesion characteristics of UV-aged asphalt after regeneration were studied by considering different influencing factors. It was found that the regeneration improved the asphalt's adhesion and resistance to water damage. Moreover, appropriate stirring temperature and time further enhanced the adhesion of the regenerated asphalt.

Summary: The structures of glasses in the lithium-bismuth orthoborate composition range show deviation from the short-range order structure of crystalline end-members. The increase in bismuth oxide content leads to an increase in the fraction of tetrahedral boron and a continuous rise in glass transition temperature. However, the glass stability reaches a maximum in the multicomponent glass of x = 40.

Summary: This study investigated the effects of different drying methods on the quality of Amomum tsao-ko, finding that sun drying and electric baking drying at 50 degrees Celsius resulted in the highest volatile oil content. Different drying methods significantly impacted the main components of the fruit and were negatively correlated with fruit cracking and mildew rates.

Summary: This study investigates the changes in carotenoid concentration in extra virgin olive oil (EVOO) as it oxidizes under accelerated thermal aging using resonant Raman spectroscopy (RRS). The conventional method, HPLC, used to determine carotenoid concentration is costly and time-consuming. The study finds that the resonant Raman technique amplifies the weak carotenoid signals and identifies Raman intensity ratios as indicators of aging effects.
