K. Reza Kashyzadeh, M. A. Ganjabi, S. Moghbeli, A. N. Ramzi Hassan, S. V. Khlopkov, M. Laad
International Journal of Engineering Transactions B Applications, 2026
The Resistance Spot Welding (RSW) technique is a prevalent method for joining thin metal sheets, particularly in transportation-related industries such as automotive and aerospace. A key advantage of RSW lies in its efficiency and the absence of additional materials, which contribute to structural weight reduction. In this study, the influence of visible defects (i.e., edge and intersection) on the mechanical behavior of triple-layer welded joints under static and fatigue loads is analyzed. To this end, a combination of laboratory testing and Finite Element Modeling (FEM) was utilized. The FEM approach was validated using experimental axial fatigue data (high-cycle S-N curves). Unlike prior research, this investigation incorporates such as surface-level defects into the FEM framework for the first time. Simulation results showed that a 0.2 mm edge defect leads to tensile and fatigue strength decrease of 5.4 % and 13.72 %, respectively, while a 0.6 mm intersection defect for the static and fatigue strengths causes reduction of 9.6 % and 54 %, respectively. These findings highlight the fatigue strength’s higher sensitivity to such defects compared to tensile strength.

Development of hybrid graphene–biochar–metal foam composites phase change materials for building applications
Sapana Dhabarde, Meena Laad
Materials for Renewable and Sustainable Energy, 2026
Innovative research into thermal energy retention materials that improve interior thermal efficiency and lower overall energy consumption is prompted by the growing need for energy-efficient buildings. Phase change materials are known for their enormous latent heat storage capacity; however, issues with low thermal conductivity, leakage, and structural stability following repeated thermal cycling limit their practical application. This review work investigated the creation of hybrid biochar-metal foam PCM composites in order to overcome these problems. By adding graphene, rapid heat absorption and release rates are obtained, which considerably enhance thermal conductivity. Biochar, which is produced by pyrolyzing agricultural waste, offers a lightweight, extremely porous, economical, and environmentally acceptable matrix that reduces PCM leakage and promotes capillary-driven form stability. Benefits of metal foam include homogeneous heat distribution, good mechanical resistance, and structural strengthening. PCM is injected into hybrid scaffolds using the vacuum impregnation process to create form-stable composites that improve thermal transfer and minimize leakage. The findings demonstrate the use of composites in thermal-regulating wall panels, roofing systems, and passive energy-saving envelopes. For the future generation of high-performing, energy-efficient buildings, this PCM composite hybrid graphene-biochar-metal foam offers sustainable TES materials. Graphical abstract

SrFe 12 O 19 -based sensors face challenges related to synthesis control, structural stability, and performance optimization, which hinder their widespread application. The size, shape, crystallinity, and functional behaviour of SrFe 12 O 19 particles are all modified by synthesis techniques, which directly affect sensor efficiency. Further, dopant inclusion (Co, Zn, Ni, and rare-earth elements) and nanostructuring are essential aspects that improve sensor stability, sensitivity, and selectivity; nevertheless, additional research is needed to determine their precise contributions. Several synthesis techniques, such as sol-gel, co-precipitation, hydrothermal, solid-state, and microwave-assisted processes, are critically examined in this review and connected to the structural and magnetic characteristics that control sensor performance. It also highlights recent developments in SrFe 12 O 19 -based gas, humidity, biosensors, and electromagnetic sensors while pointing out long-term stability and temperature sensitivity issues. Furthermore, optimization techniques, such as hybrid sensor designs, composite constructions, and material modifications, are investigated to improve reaction time and reliability. This review offers a thorough resource on the connection between synthesis techniques, material characteristics, and sensor efficiency for researchers working on next-generation ferrite-based sensors.

Scientific Reports, 2025
Lightweight polymer composites have drawn a lot of interest because of their improved mechanical, electrical, and thermal properties, which make them perfect for cutting-edge engineering applications. This work reports the synthesis of hybrid polymer composites by integrating multi-walled carbon nanotubes (MWCNTs) into a polyvinylidene fluoride (PVDF) matrix. The synergistic effect of MWCNTs and graphite nanoparticles was explored to achieve improved structural and functional performance. The composites were synthesised using a solution casting method to ensure dispersion of the fillers within the polymer matrix. The fabricated composite was characterized using XRD, FTIR, EDS and FESEM to evaluate its structural, compositional, morphological and elemental properties. XRD confirmed the nanofillers' crystalline phases and structural integrity within the polymer matrix. FTIR spectroscopy identified the characteristic functional groups, verifying interactions between PVDF and the incorporated nanofillers. FESEM images revealed a fibrous CNT network blended within the PVDF polymer matrix and distinct graphite flakes, ensuring uniform dispersion and adhesion. EDS confirmed the elemental composition, highlighting the presence of carbon and fluorine as primary constituents. These combined techniques provide comprehensive insight into the composite's composition, structure and potential functional properties for advanced applications.
