This Topic brings together interdisciplinary research in science and technology, encompassing (but not limited to) the following areas:

• Science and technology of materials;
• Physics and applied mathematics;
• Industrial and environmental chemistry;
• Analytical chemistry;
• Intelligent systems and electronic technologies;
• Product design, development, and engineering;
• Computerized, robotic, and neuromorphic industrial systems;
• Computer architecture and technology;
• Coatings and nanostructured materials;
• Development of functional materials for additive manufacturing (i.e., applications in biomedicine);
• Advanced optical characterization of nano- and microstructures and thin films;
• Biopolymers from agro-food bioresidues;
• Interfacial rheology and its applications;
• Deep learning systems for diagnosis, prevention, and pattern recognition;
• Bio-inspired systems for sensory fusion and control;
• Artificial intelligence in smart city applications;
• Energy forecasting and flexibility services;
• Advances in food and by-product development and characterization;
• New trends in sustainable cities and industries;
• Intelligent and sustainable optimization of industrial engineering projects;
• Multifunctional and smart toys for children with autism spectrum disorders;
• Weighting in life cycle assessment with cradle-to-cradle design (quantitative methodology for global sustainability design and social and socio-economic life cycle assessments) in small- and medium-sized enterprises;
• Analysis of emerging pollutants in environmental samples;
• Biomechanical and biofunctional behavior of porous materials.

Currently, acne therapy relies not only on specific drugs but also on complementary treatments, such as dermocosmetics. Several studies have reported the use of chitosan and alginate in scaffolds for drug delivery systems. These materials can be loaded with a product that exhibits anti-acne properties such as silk sericin, a protein with antioxidant, photoprotective, and moisturizing properties. Therefore, this study proposes the development of a chitosan/alginate scaffold, loaded with sericin, to serve as a dermocosmetic platform complementing the pharmacological treatment of acne. The moisture content of the alginate and chitosan was determined as 14.7 and 21%, respectively; the ash content, which is similar for both polymers, was approximately 5%. The employed chitosan had a deacetylation degree of 82%, as determined by infrared spectrometry and corroborated by potentiometry. This technique was also used to determine the mannuronic/guluronic ratio of the alginate [M/G = 1.3] and confirm the identity of each one of the polymers in the raw materials and the resulting scaffolds. The molecular weights of alginate, chitosan, and sericin were 85, 5.1, and 57.4 kDa, respectively. The pH [6.31] and total protein concentration of the sericin solution [c(SER) = 6.1 mg/mL] were determined using UV-visible spectrophotometry. Swelling and release studies indicated that, although there were varying degrees of cross-linking and certain variables to control, the mechanism that defines the nature of both processes (otherwise complementary) is the relaxation of the polymer chains.

Considerable attention has been given to addressing side-channel attacks to improve the security of cryptographic hardware implementations. These attacks encourage the exploration of various countermeasures across different levels of abstraction, through masking and hiding techniques, mainly. In this paper, we introduce a novel hiding countermeasure designed to mitigate Correlation Power Analysis (CPA) attacks without significant overhead. The new countermeasure interferes with the processed data, minimizing the power correlation with the secret key. The proposed method involves using a Correlated-Power-Noise Generator (CPNG). This study is supported by experimental results using CPA attacks on a SAKURA-G board with a SPARTAN-6 Xilinx FPGA. An Advanced Encryption Standard (AES) cipher with 128/256-bit key size is employed for this purpose. The proposed secure design of AES has an area overhead of 29.04% compared to unprotected AES. After conducting a CPA attack, the acquisition of information about the private key has been reduced drastically by 44.5%. Full article
