Sonochemistry is the use of ultrasonic waves in an aqueous medium, producing acoustic cavitation. In this context, sonochemistry emerged as a focal point over the past few decades, starting as a manageable process such as radar or cleaning technique; now, it is finding wide‐ranging applications across various chemical, physical, and biological processes, creating an opportunity area of analysis between these areas. Sonochemistry is a powerful and eco‐friendly technique often called “green chemistry” for less energy use, toxic reagents, and residues generation, among others. It is increasing the number of applications achieved through the ultrasonic irradiation (USI) method. Sonochemistry has been established as a sustainable and cost‐effective alternative in comparison with the traditional industrial methods, promoting scientific and social well‐being, offering no‐destructive advantages, including rapid processes, improved process efficiency, enhanced product quality, and, in some cases, the retention of key quality characteristics of the products. This versatile technology has significantly contributed to the food industry, materials technology, environmental remediation, and biological research. This review is created with enthusiasm and focus on shedding light on the manifold applications of sonochemistry. It delves into this technique's evolution and current applications in cleaning, environmental remediation, microfluidic, biological, and medical fields.

“…Natural disasters such as intense wind and heavy rainfall can trigger the falling off of shingles and connecting roof parts, thereby diminishing the roof's water resistance and causing leaks. Earthquakes, on the other hand, can instantaneously damage a building's structure [65]. Environmental pollution can directly impair the material composition of cultural heritage.…”

Historic sites are important components of every city’s cultural history because they preserve rich historical knowledge and distinctive values passed down from previous generations to the present. Due to the progress of urbanization and modernization, many historic sites face pressure from damage and transformation. In this paper, a method for assessing cultural heritage damage was developed to measure the extent of spatial damage in historic sites. Using sample data obtained in Xiyang, Qi, and Xiaoyi, all historic cities in Shanxi Province, Mainland China, and combined weights were estimated using the Delphi technique and the CRITIC weight method. Following this, the Spatial Damage Degree Model (SDDM) based on K-means cluster analysis and K-nearest neighbor (KNN) classification was developed. The findings show that the model efficiently solves the problem of assessing spatial damage levels in historic sites. Through multiple linear regression analysis, it was shown that the damage to historic sites was predominantly caused by three factors: natural erosion, construction damage, and planning and policy. SDDM was used to calculate the spatial damage levels of historic sites, allowing conservators to fully comprehend the features and concerns related to historic sites. As a result, more scientific and rational preservation approaches can be developed, improving the efficiency of historic site restoration and conservation, and encouraging the sustainable development of urban and rural heritage.

“…In cultural heritage preservation, these coatings are used as stone consolidants to extend the longevity of historic stone-wall constructions. 8–10 TEOS–PDMS coatings also exhibit versatility in engineering and material science. They act as corrosion barriers on metal surfaces, 11 elongating material lifespans, while in cementitious contexts, they enhance mechanical properties, bolstering structural durability.…”
