Scalable Laser Manufacturing of High‐Aspect‐Ratio Superhydrophobic and Ferromagnetic Microcilia Arrays for Aqueous Droplet Transportation Biological cilia exhibit metachronal movements that enable the expulsion of substances such as mucus and bacterial cells. Inspired by biological cilia, significant progress has been made in recent years in the development of artificial cilia. In particular, magnetic actuation has emerged as a prominent strategy for real-time, remote-controlled manipulation, offering noninvasive and reversible operation without inducing irreversible damage. However, the fabrication of artificial microcilia is currently constrained by limitations in achieving high aspect ratios, cost-effectiveness, and scalable production. In this study, advanced laser manufacturing is used to drill porous silicon (Si) templates, successfully demolding microcilia with a high aspect ratio (exceeding 9). By integrating silicon dioxide (SiO<sub>2</sub>) nanoparticles, a superhydrophobic surface is achieved with a hierarchical micro-nano structure. The experiments demonstrated that these structured microcilia not only exhibit remarkable durability but also maintain long-term superhydrophobicity. Furthermore, by blending with magnetic iron (II, III) oxide (Fe<sub>3</sub>O<sub>4</sub>) nanoparticles, superhydrophobic magnetic microcilia arrays (SMMA) are developed, enabling droplet transportation on their surface controlled by an external magnetic field. These artificial microcilia have potential applications in biomedical devices, self-cleaning anti-fouling surfaces, and human sensing technologies.

Development and Validation of a Simultaneous HPLC Stability-Indicating Method for Atorvastatin and Apigenin in a Novel SMEDDS Formulation Using Quality by Design (QbD) Approach Atorvastatin (ATV), a widely used statin, exhibits both cholesterol-lowering and anti-inflammatory effects. Apigenin (API), a natural flavonoid, also demonstrates potent anti-inflammatory activity. This study aimed to develop and validate a novel stability-indicating reverse-phase HPLC method for the simultaneous quantification of ATV and API in standard solutions and dual ATV–API-loaded self-microemulsifying drug delivery system (SMEDDS). Quality by Design (QbD) approach was used to define the quality target product profile (QTPP), critical quality attributes (CQAs), and identify critical method parameters (CMPs) through risk assessment. A central composite design (CCD) evaluated the effects of organic phase ratio, buffer pH, and flow rate on chromatographic responses, including retention time, tailing factor, and resolution. Separation was achieved using an Agilent Eclipse XDB C-18 column (5 µm, 4.6 × 150 min) with a mobile phase of acetonitrile and 0.1 M ammonium acetate buffer (pH 7.0) in a 40:60 (v/v) ratio, UV detection at 266 nm, and a flow rate of 0.4 mL/ min. The method met ICH and USP (2021) validation criteria, showing excellent linearity (0.1–10 µg/mL), precision, accuracy, and specificity. No interference from SMEDDS excipients or degradation products during stability studies was observed. This validated method offers a reliable tool for formulation development and routine analysis of ATV and API combinations Quality by Design ; Ammonium acetate ; Critical quality attributes ; High-performance liquid chromatography ; Retention time ; Volumetric flow rate ; Apigenin ; Design of experiments Analytical Methods in Pharmaceuticals ; Analytical Chemistry and Chromatography ; Computational Drug Discovery Methods

How can we make Bioenergy and Useful Products from Olive Waste? Have you ever wondered what happens to the leftovers from plants and fruits, like the pulp left after making juice or oil? These leftovers are called biomass, and instead of throwing them away as waste, we can reuse them. Scientists are discovering smart ways to turn biomass into useful things—a process called valorization. This article looks at olive waste biomass, which is the material left after making olive oil. With special tools and processes, olive biomass can be changed into energy to heat homes, fuel for cars and trucks, or ingredients for cosmetics and medicines. By learning the chemistry behind olive biomass you will discover how to reuse it, which protects the environment, and supports local communities. This idea is part of what is called a circular economy, where nothing is wasted and everything gets reused—helping to build a cleaner and better future for everyone.

HPLC-Based Elucidation of Tannins from the Tissue and Callus Culture Extracts of Selected Medicinal Plants Background. Optimized HPLC profiling is a powerful and effective analytical tool to standardize plant samples and authenticate plant materials. In this study, three selected medicinal plants namely: Achyranthes aspera, Ipomoea hederacea, and Ocimum basilicum were subjected to callus induction following seedling, leaf, and stem germination. Methods. The induced callus was subsequently dried, finely ground, and extracted using methanol and water for HPLC analysis. A validated procedure was employed to identify and separate the tannin content in seedling leaf, stem, and callus culture extracts. HPLC fingerprinting was performed using a Shimadzu LC-20A system with a retention time of 2.9 minutes at 270 nm. The aim was to ensure quality and consistency in tannin analysis across different plant parts and callus culture samples. Results. The highest callogenic response occurred in A. aspera leaf explants on MS medium with 2.0 mg/L 2,4-D and 4.0 mg/L NAA, producing green, granular callus. The lowest was in I. hederacea stem explants with 0.5 mg/L 2,4-D and BAP, yielding brown, granular callus. O. basilicum leaf callus extract showed the largest sample area (9365.56) and tannin content (2.66), with superior precision in tannin analysis for O. basilicum and A. aspera (7.81). Conclusion. HPLC profiling proved to be an accurate, efficient, and precise method for evaluating tannin content in selected plant samples. It is a crucial method to standardize the quality of medicinal plant compounds.

Comparative Performance and Cost-Effectiveness Analysis of Scientific Methods for Durian Ripeness Assessment: International Practices, Regional Development and Implications for Thailand The export supply chain of Thai durian has so far relied heavily on manual fruit inspection for maturity testing, which has 70 to 80% accuracy when conducted at a packinghouse. Manual inspection is no longer valid in terms of the SPS and NTMs of importing countries, labor shortages during harvest time, and it is no longer competitive with new durian-producing countries such as Vietnam and Malaysia. This paper reviews non-destructive techniques for monitoring fruit maturity, such as NIR/Vis, NIR spectroscopy, HSI, AI-based computer vision, acoustic technology, in-field IoT monitoring, and the cost and performance analysis of the techniques under the SPS and NTMs for durian export. From the literature review, the most promising technique for further development is NIR, with over 94% accuracy, fruit-sorting capacity of 600 to 1,200 pieces per hour, and an initial investment of USD 15,000 to 150,000. In addition, this paper presents step-by-step investment planning for the fruit grading system and discusses future work on establishing a national durian spectral database and conducting a real packing-house test run to make the system ready for deployment of the technology-based fruit grading system for Thai-exported durian.

The formation energy of triple lines Abstract Triple lines occur where three grain boundaries intersect and are an intrinsic part of the defect structure of a material. Grain boundaries and dislocations both contribute a positive excess energy as they represent a deviation from the pristine lattice. By contrast, a triple line is formed within an already defective region of a material and so the formation energy need not be positive. A Gibbsian method is presented to find the formation energy of a triple line in a model for aluminium using molecular dynamics exploiting the symmetry of two related simulation cells. Approximately 83% of our 615 simulations produced a negative triple line formation energy with a moderately strong negative correlation with the mean excess grain boundary energy of the adjoining grain boundaries. The triple line formation energy was particularly sensitive to changes in its position and the associated spatial gradient provides an additional force acting on the triple line which is not included in the Herring relationship. Furthermore, this energy gradient would contribute to the driving force acting on a triple line and influence the drag effect of triple lines during grain growth.

Challenges and Opportunities in Sustainable Food Applications The historical co-production of olive oil and wine has influenced the Mediterranean landscape and economy. Olive oil and wine production generates substantial organic waste, including olive pomace, grape pomace, and wastewater, which poses environmental challenges if untreated. These byproducts contain bioactive compounds, including polyphenols, such as hydroxytyrosol, resveratrol, and flavonoids, which possess antioxidant and anti-inflammatory properties, making them valuable for the development of functional foods and nutraceuticals. A combined waste valorization strategy can enhance bioactive compound recovery and align it with circular economic principles. The incorporation of olive oil and wine byproducts into food matrices, such as bread, pasta, dairy products, baked goods, chocolates, beverages, and processed items, has been explored to enhance antioxidant content, dietary fiber, and nutritional value. However, successful integration depends on maintaining acceptable sensory qualities and addressing the technical challenges in extraction, processing, and regulatory compliance. Realizing the potential benefits of dual valorization requires a systemic shift integrating scientific innovation, regulatory adaptability, and consumer engagement, guided by evidence, transparent communication, and inclusive governance to ensure that sustainability goals translate into environmental, economic, and public health outcomes.

Design and Development of an Automatic Asem Keping Drying System Using Infrared Heater Based on Fuzzy Logic The drying process of Asam Keping (Garcinia atroviridis) is a crucial stage in food processing that significantly affects the final product quality. Conventional drying methods that rely on sunlight have several limitations, such as dependency on weather conditions, extended drying time, and inconsistent results. This study aims to design a drying system for Asam Keping controlled using the fuzzy logic method. The research is expected to improve energy efficiency, accelerate the drying process, and maintain the quality of the dried product. The drying system is designed using an infrared heater as the heat source, temperature and humidity sensors to monitor environmental conditions, and a microcontroller as the main controller. The fuzzy logic method is implemented to adjust the drying temperature and duration adaptively based on environmental parameters and the desired dryness level. The results of this study are expected to reduce drying time by approximately 50% compared to conventional methods. Additionally, the dried Asam Keping is expected to achieve the desired moisture content while preserving its color and texture quality. The analysis of this study concludes that an infrared heater-based drying system utilizing fuzzy logic can be an effective solution for the Asam Keping drying process in terms of time efficiency and product quality.

Investigation of Strength of Polymer Matrix under the Influence of Temperature Time Factor BACKGROUND: The widespread use of polymer composite materials (PCM) in the shipbuilding industry necessitated the study of the physical and mechanical properties of PCM, including under the influence of temperature time factor, which are important and timely. This is further supported by the need to improve the technology of using polymers in the form of thin antifriction coatings in critical machines. AIM: To investigate the strength of polymer matrix under the influence of temperature time factor by preparation of materials and samples for experiments; study of changes in the polymer matrix at different composite sintering temperatures; study of the synthesis (growth) of polymer strength; building mathematical models of polymer strength growth at different temperatures from 200 to 350 °C; study of the polymer strength loss (destruction). METHODS: PA-6/66-3 polyamide, which has been in high demand lately, was selected for the study. Both theoretical research methods and empirical ones were used, including high-tech experiments using digital technologies and processing using CAE software. RESULTS: It was found that the sintering temperature of a polymer determined the strength growth rate and the dependence of the strength growth rate on temperature was linear. Dependence graphs of the tensile strength and the sintering time at various temperatures are shown and experimental curves are approximated. It was revealed that the polymer thermal degradation proceeded up to the specified tensile strength and had a pronounced inflection point. CONCLUSION: The study shows that the law of strength growth (synthesis) can be represented as a linear dependence on the sintering temperature of the samples. We can conclude that the coefficients in the equation of the direct rate of strength growth depend significantly on the melting point. The study allows us to make recommendations on improving the manufacturing technology of dispersed polyamide products.
