Natural astaxanthin is synthesized by diverse organisms including: bacteria, fungi, microalgae, and plants involving complex cellular processes, which depend on numerous interrelated parameters. Nonetheless, existing knowledge regarding astaxanthin biosynthesis and the conditions influencing astaxanthin accumulation is fairly limited. Thus, manipulation of the growth conditions to achieve desired biomass and astaxanthin yields can be a complicated process requiring cost-intensive and time-consuming experiment-based research. As a potential solution, modeling and simulation of biological systems have recently emerged, allowing researchers to predict/estimate astaxanthin production dynamics in selected organisms. Moreover, mathematical modeling techniques would enable further optimization of astaxanthin synthesis in a shorter period of time, ultimately contributing to a notable reduction in production costs. Thus, the present review comprehensively discusses existing mathematical modeling techniques which simulate the bioaccumulation of astaxanthin in diverse organisms. Associated challenges, solutions, and future perspectives are critically analyzed and presented. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

This article covers the potential of MXenes as a versatile solid lubricant. MXenes are recognized for their potential across diverse applications ranging from energy storage to fields like biology and medicine. Recently, MXenes research experienced rapid growth in understanding the tribological characteristics due to the outstanding mechanical properties and chemical reactivities. The commercial applications are restricted due to the limited research on MXene-doped composites. The laid down physics, responsible for the improvement in the physical and functional properties is also important for better understanding. Hence, in this effort, the cutting-edge application of MXenes with other matrices is thoroughly discussed. This review explores the potential of next-generation MXenes, highlighting key factors that enhance their tribological properties and the fundamental mechanisms behind them. Later discussions highlight the application of MXenes with various matrices and their future importance. Lastly, the fundamental physics to improve MXene properties concisely concluded with the potential of future research. © 2025 The Korean Society of Industrial and engineering Chemistry

Effect of Build and Scan Direction on Tensile Properties of Selective Laser Melted SS316L Alloy

Lasers in Manufacturing and materials Processing 2023年第2期10卷 330-352页

Sinha, Niraj Department of Mechanical Engineering Indian Institute of Technology Kanpur208016 India Department of Materials Science and Engineering Indian Institute of Technology Kanpur208016 India Department of Mechanical and Aerospace Engineering New York University Tandon School of Engineering BrooklynNY11201 United States

Process-microstructure-mechanical property linkage was established for selective laser melted SS 316 stainless steel alloy by studying the role of scan direction and build direction on the tensile properties of the alloy with detailed microstructural characterization using electron backscatter diffraction. A wide range of mechanical properties comprising a range of ductility from 78 and 35% with a range of yield and ultimate strength of 275 to 313 MPa and 342 to 428 MPa, respectively, for the alloy, shows the capability of selective laser melting to cover a large property space. Similarly, a wide toughness range of 11,970 to 27,760 MJ/m3 is such that the sample with the scan direction perpendicular to the plane containing the tensile axis shows the highest toughness. The synergy of strengthening and strain hardening mechanisms like Taylor hardening, dislocation strengthening and twin induced plasticity to modulate the properties of SS316L alloy is established.

11th ASPE-euspen Summer Topical Meeting on Advancing Precision in Additive Manufacturing

Vat photo polymerization (VPP) is an additive manufacturing (AM) method that creates 3-dimensional parts by projecting 2-D grayscale images created by digital light processing (DLP) masks with digital micromirror devices (DMD) at photo-sensitive resin vats layer by layer. Recent advancement in the VPP method has been made by using multiple DLP systems at different wavelengths to selectively initiate different resins curing mechanisms or activate inhibition reactions. This expands the basic VPP method to allow for multi-material printing and increases geometry precision control. As multiwavelength VPP technologies advance, development of two-wavelength DLP light delivery technology needs to be documented and formalized. In this work, the current state-of-the-art applications of dual-wavelength VPP printers are examined, and an orthogonal VPP printer using custom optics and control is developed with the help of ray tracing simulations. The intensity distribution, geometrical accuracy, precision, and spatial distribution of each projected single-wavelength exposure mask, as well as the alignment of the two-wavelength exposure masks, are quantified using a high-resolution CMOS camera and power meter and compared with other systems in literature. The developed optics system aims to achieve two-wavelength optical exposures characterized by high resolution, precise alignment, and desired intensity distribution. Designed with compatibility in mind, this optics system will allow for integration with mechanized platform as well as customized metrology and process control technologies, thereby establishing a strong foundation for precise, reproducible, and robust 2-wavelength VPP for advanced applications. © 2024 2024 ASPE.

A nonlinear aeroelastic model for a flexible panel is expanded to consider the effect of the viscous boundary layer using a RANS solver. This study presents the use of a Reduced Order Model (ROM) to compute the generalized aerodynamic force from a CFD simulation and compares the results obtained using the same approach with an inviscid solver and the analytical implementation of Full Potential Flow Aerodynamics. The flutter onset critical condition is obtained based on the Limit Cycle Oscillation amplitudes, for different supersonic Mach numbers. Additionally, the effect of different viscous boundary layer thicknesses is explored. Conclusions are made based on the use and application of this more complete aerodynamic theory, particularly for near transonic Mach numbers. © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA.
