Morphological control synthesis of layered double hydroxides for energy applications Layered Double Hydroxides (LDHs), a versatile class of anionic clays, offer unique advantages, such as adjustable metal cation ratios, expandable interlayer spaces, and surface modifiability, which critically influence their functionality in energy storage and conversion technologies. However, the structural parameters of LDHs, including morphology, particle size, and crystallinity, are heavily dependent on synthesis methods and reaction conditions. This review systematically explores the intricate relationships between synthesis approaches, such as co-precipitation, hydrothermal synthesis, sol-gel methods, electrochemical deposition, calcination-recovery, exfoliation, and microwave-assisted synthesis, and the resulting LDH structures. Emphasis is placed on tailoring LDH morphologies to meet the demands of energy applications, such as enhancing charge storage in supercapacitors, optimizing ion diffusion in batteries, and improving catalytic activity for water-splitting technologies. Key reaction parameters, including pH, temperature, reaction duration, and the role of additives and templates, are analyzed for their impact on LDH characteristics. Additionally, advanced characterization techniques, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray absorption spectroscopy (XAS), Inductively coupled plasma (ICP), and thermogravimetric analysis (TGA), are reviewed for their role in understanding LDH structures. Finally, the challenges of cost-effectiveness and scalability are discussed, highlighting future research directions that aim to optimize LDH synthesis for practical energy applications.

Beyond the four core effects: revisiting thermoelectrics with a high-entropy design Low-exergy waste heat, which constitutes the majority of industrial-scale thermal losses, remains largely unrecoverable with conventional technologies. Thermoelectrics offer a solid-state solution for converting this hard-to-access energy into electricity, making them attractive for decentralized power generation and sensor applications. High-entropy materials (HEMs) have gained traction as a strategy for better-performing thermoelectrics, but the mechanisms driving their benefits require further exploration. This article highlights key insights for heat and electronic transport in HEMs. For heat transport, we argue that reduced, and often ultralow, lattice thermal conductivity in HEMs-with respect to ordered counterparts-can be taken for granted, emerging naturally as a fifth core effect of high-entropy systems. While band convergence is often considered beneficial for electronic transport, its impact depends strongly on the electronic structure. We summarize the scenarios where it can be detrimental to thermoelectric performance. These insights motivate strategies that align seamlessly with advancements in artificial intelligence and data-driven approaches, helping accelerate the discovery of next-generation thermoelectric materials.

Crystal Structures and Corrosion Inhibitions of Three Cobalt Complexes of Terephthalate Anion and Bis‐Nitrogen Donor Ligands ABSTRACT Three Co(II) complexes of terephthalate anion containing 1,10‐phenanthroline (phen) or 2,2′‐bipyridine (2,2′‐bipy), are prepared. The structures of dimeric [Co 2 (H 2 O) 4 (μ‐H 2 O) 2 (phen) 2 ] 4+ ·2(C 8 H 4 O 4 2− ), 1 , and the polymeric [Co 2 (H 2 O) 2 (phen) 2 (μ‐C 8 H 4 O 4 ) 2 ] n , 2 , complexes were confirmed by single crystal structure determination. Both complexes have CoN 2 O 4 core in a distorted octahedral arrangement. Extensive hydrogen bonding and π–π stacking interactions consolidate 3‐D structures in 1 and 2 . Complex 3 , [Co(μ‐C 8 H 4 O 4 )(2,2′‐bipy)] n , was previously reported. It has CoN 2 O 4 core in a distorted trigonal prismatic environment. Complexes 1 , 2 and 3 exhibited good inhibition efficiencies for corrosion of carbon steel in 0.25‐M sulfuric acid solution. The order of corrosion inhibiting effect of the complexes was 2 (94.6%) &gt; 1 (90.5%) &gt; 3 (79.5%). The increase in R p value and the decrease in C dl were in parallel with the increase in the concentration of complexes. Tafel plot indicated that complex 1 behaved as a cathodic‐type corrosion inhibitor, whereas complexes 2 and 3 as anodic inhibitors for C‐steel in sulfuric acid medium. Weight loss measurement of steel samples in 1‐M HCl showed more inhibition of corrosion by complexes 1 and 2 than by complex 3 . The adsorption mechanism of inhibitors on C‐steel followed Langmuir isotherm. The free energy changes indicated comprehensive physical and chemical adsorption for the three complexes on the surface of the C‐steel. SEM analysis of steel samples in 1‐M HCl proved the efficiency of complexes in retarding corrosion as the steel surface showed smoothness compared to the blank. Quantum chemical DFT study declared that the highest corrosion inhibition efficiency is observed for complex 2 , which was strongly supported by the electrochemical anticorrosion studies. The results of the TGA analysis support the X‐ray crystal structures of the complexes.
