  • Carbon Quantum Dots: Synthesis Strategies, Optical Mechanisms, and Emerging Biomedical and Energy Applications—A Review
    Vrinda V. Katti, Vibhashree Vasuki, V. Megha, Shreya Hanimanal, Manav Verma, Chandra Kumar R, Sivakumar Solaiachari
    Chemistryselect, 2026
    Carbon quantum dots (CQDs) are zero‐dimensional nanomaterials known for their small size, adjustable particle dimensions, great biocompatibility, low toxicity, and water solubility. Their unique properties include fluorescence stability and a wide excitation spectrum that enables a range of applications across various fields. This review focuses on the synthesis methods employed for CQDs which includes both top–down approaches (e.g., electrochemical synthesis, acid oxidation synthesis) and bottom–up techniques (e.g., hydrothermal synthesis, pyrolysis) and properties of CQD like structural, optical, and biological properties. It also explores the diverse applications of CQDs in biomedical fields like bioimaging, drug delivery, biosensors, cancer treatment through photothermal and gene therapy. Some of the other applications are solar cells, toxin detection, and LEDs.
  • Optimization of Vibrational Characteristics of 3D Printed Lattice Structured Lightweight Curved Beams Using Genetic Algorithm Approach
    Rahul B N, Jeevathith R, Bharatish A, Sivakumar Solaiachari
    Applied Research, 2026
    The vibrational behaviour of lightweight structural components, such as curved beams, is acutely sensitive to changes in geometric parameters, making the optimization of modal characteristics a crucial goal in vibration‐sensitive applications. While the specific effects of geometry on natural frequencies have been examined, a comprehensive synthesis of experimental and simulation data for optimal design identification remains limited. This study addresses the gap by adopting a hybrid methodology that integrates experimental modal analysis and finite element simulations with a Genetic Algorithm (GA)–driven optimization technique. A total of 27 design combinations, generated using a Taguchi Orthogonal design (L27) framework, were evaluated experimentally through an 8‐channel Dewesoft FFT analyzer, impact hammer, and dual‐accelerometer arrangement, as well as numerically. Curved beams with Triply Periodic Minimal Surface (TPMS) gyroid lattice infills were fabricated using Fused Deposition Modeling (FDM), and the first six vibrational modes were extracted to establish a surrogate model linking beam width, unit cell size, wall thickness, and infill density with modal frequencies. The GA‐based search identified an optimal configuration with a beam width of 18 mm, unit cell size of 9.83 mm, wall thickness of 1.47 mm, and infill density of 20.37%. This design achieved a consistent average frequency of ~1415 Hz in both experimental and simulated environments, validating the accuracy of the surrogate model and robustness of the test setup. The findings emphasize the dominant influence of beam width and wall thickness on frequency augmentation and demonstrate the effectiveness of metaheuristic algorithms, particularly the crossover‐driven genetic search dynamics, in optimizing vibration‐sensitive lightweight structures.
  • Surface quality and i-v characteristics of laser-welded thin foils of copper/stainless steel/copper stack for lithium-ion battery manufacturing

    Surface Review and Letters, 2026
    The production of lithium-ion batteries for electric vehicles relies heavily on the dissimilar welding of thin copper and stainless-steel foils using laser beams. Despite its technological advances, optimization strategies for the stack welding of thin foils still remain unexplored. This paper examines the feasibility of laser welding of copper/stainless steel/copper foil stacks using a 20[Formula: see text]W nanosecond pulsed laser. The effect of scanning speed (250 to 300[Formula: see text]mm/s) on the laser welding characteristics, such as heat-affected zone (HAZ), surface roughness, microstructure and electrical resistance, was systematically assessed. The results showed that enhancing the scanning speed reduced HAZ from 317.81[Formula: see text] [Formula: see text]m to 240.67[Formula: see text] [Formula: see text]m, constituting a decrease of 24.27% and the surface finish improved by 11.6%. Microstructure of thin stacked foils revealed that the optimal metallurgical bonding and minimal porosity could be obtained at a lower scanning speed of 250[Formula: see text]mm/s whereas higher scanning speeds can result in crack formation and incomplete fusion. Electrical resistance measurements using an Agilent B1500[Formula: see text]A semiconductor device analyzer demonstrated that impurities and interface defects significantly influence current-voltage (I–V) behavior, emphasizing the relationship between weld quality and electrical performance. Thus, a critical processing window for effective dissimilar welding of thin foils was established.

  • Enhancing Laser Cut Quality of Copper Thin Foils for Lithium-Ion Batteries through Pre-Cooling and Teaching-Learning-Based Optimization
    Akshay P. Rao, A. Bharatish, Sivakumar Solaiachari, S. Mahendra Kumar
    SAE International Journal of Materials and Manufacturing, 2025
    <div>The efficiency and performance of lithium-ion batteries are highly influenced by the quality of laser cutting of electrode materials. The laser cut quality of thin foils is often measured by amount of kerf width and heat-affected zone (HAZ). This article adopts a novel approach that involves pre-cooling of thin copper foils prior to the laser cutting process. The impact of laser conditions and foil temperature were analyzed on HAZ and kerf width induced during laser cutting experiments conducted based on L27 orthogonal array. Teaching–learning–based optimization (TLBO) technique was employed to identify the optimal laser parameters. ANOVA results indicated that the temperature was the most significant factor influencing kerf width and HAZ. The optimized laser parameters identified through TLBO technique were 16 W laser power, 69.47 mm/s scanning speed, and 20 kHz pulse frequency at dry ice conditions. A reduction of 50.76% kerf width and a decrease in 7.6% HAZ were observed when the foils were cut at dry ice conditions. The quality of cut surfaces were further examined using scanning electron microscope.</div>

    Tribology Materials Surfaces and Interfaces, 2025
    A cerametallic friction pad (CMDE) was developed through the Powder metallurgy route and validated through a classical SAEJ 661 standard laboratory test (Chase Testing machine) followed by the field test. The same was compared with an imported OE (CMOE) pad. In the chase test, CMDE fared poorly in fade-1 by 25% concerning the reference value but fulfilled the fade-II and recovery characteristics. From a wear viewpoint, the specific wear rate of CMDE and CMOE are marginally close. Considering the wear in the field test, CMDE has shown 11.1% more wear than CMOE, but 20% less wear in the mating part. More reduction in the surface roughness of CMDE after the field test evidenced its engagement characteristics by deforming asperities. Adhesive wear scoring marks were visible along the sliding direction of the pressure plate and the sintered friction pad. Thus, CMDE has the potential to replace CMOE in performance and cost
  • Hybrid glass-carbon fiber composites for solar greenhouse dryer trays: a 3D computational analysis
    Rajesh Kumar, ShenbagaVinayaga Moorthi Navaneethakrishnan, Sivakumar Solaiachari
    Advanced Composite Materials, 2025
    A 3D computational study was conducted to analyze the compressive load response of a glass-carbon hybrid composite. The study varied the volume percentage of glass fibers from 0% to 100% in a composite with an overall fiber volume fraction of 0.5. Compressive instability failure was examined using ABAQUS/CAE 3D finite element micro mechanical models. The analysis assessed the behavior of glass and carbon fiber models independently before evaluating the performance of the hybrid composite.The results revealed that hybrid models exhibited superior performance at specific volume fractions. It was observed that the matrix shear yield strength played a significant role in determining compressive instability failure. Furthermore, the study demonstrated that hybrid composite turnable trays enhanced moisture removal and heat transmission during drying processes. These trays were found to be particularly suitable for outdoor solar greenhouses owing to their high strength-to-weight ratio, mechanical properties, corrosion resistance, and dimensional stability.
