Abstract The Gd3Ru4Al12 structure type compounds, where the rare-earth magnetic ions form a breathing kagome lattice present a promising material landscape for exploring the various magnetic frustration-driven exotic states of matter. Here, we highlight the various magnetic, thermodynamic, and transport properties of several of the Gd3Ru4Al12 structure type magnets and provide intuitive insights into their rich electronic and magnetic ground states. The realization of key properties such as spin trimerization and skyrmion textures accompanied by a large topological (geometrical) Hall effect (THE) in some of these compounds is currently at the heart of several research endeavors searching for efficient data storage and spintronic devices. Features such as helical ordering and anomalous Hall effect (AHE) arising from the formation of Berry curvature by the Weyl fermions present an open window to tuning the electron spins for several practical applications. Therefore, these compounds are projected as promising candidates for investigating several other topological phases of matter accessible through the interplay of the degree of frustration and crystal field symmetry of the rare-earth ions.

Abstract Externally physical fields such as stress field, electric field and magnetic field have been demonstrated influence the equilibria and kinetics of solid-state transformations in metals and alloys. This review focuses on the effects of externally physical fields on the aging precipitation of aerospace Al alloys including 2xxx Al-Cu alloys, 7xxx Al-Zn-Mg alloys as well as the advanced Al-Li alloys. While the η’ phase in Al-Zn-Mg alloy and the T1 phase in Al-Li alloy showed no obvious stress-orientating effect, the precipitation of θ’ phase in Al-Cu alloy showed obvious stress-orientating effect depending on the applied stress direction. Regarding precipitation kinetics, aging under stress field, electric field and magnetic field all can enhance the aging precipitation of aerospace Al alloys. The understanding of the effects of externally physical field on the aging precipitation in Al alloys is very preliminary. It appears that while the stress field acts on the thermally activated transformation, the athermal effect associating with electromigration of electromagnetic field has been considered responsible for the enhanced aging precipitat ion.

Abstract Supercapacitors (SCs) are currently numbered among the most outstanding energy storage and supply devices due to their high power density, durable cycle life, and wide operating temperature range. However, the wide application of SCs is still subject to the low energy density, which drives researchers to extensively look for high-performance electrode materials. In recent years, nickel sulfide-based materials have been widely studied as promising electrode materials for SCs due to their superior theoretical specific capacity, high redox activity, and rapid electric conduction, but the inferior active material utilization efficiency and poor reaction kinetics limit their practical demand in SCs. In this review, we briefly introduced the energy storage mechanism of nickel sulfide electrode materials used in supercapacitors and then launched an overview of improving performance. A particular emphasis is on the modification strategies to accelerate the electron conduction and mass transfer process through carbon recombination, metal heteroatom doping, interfacial electric field construction, exposure of edge active sites and large specific surface area, and building of ion diffusion channels. Finally, we discuss the research orientation of nickel sulfide-based electrode materials.

Abstract MXenes are recently advanced two-dimensional layered nanomaterials that have various characteristic properties for developing electrochemical sensors for bioanalytical applications, such as hydrophilicity, good biocompatibility, electrical conductivity, heightened ion transportation, and ease of functionalization. MXenes are revealed to be having applications in various other fields including energy storage, and catalysis. The combination of a layered structure, biocompatibility, and high surface functionalities makes MXene a highly versatile material for electrochemical sensing applications. The effect of various synthesis and functionalization strategies on tuning the properties of MXenes toward improving sensing abilities has been comprehensively discussed. This review article also discusses the relevance of early diagnosis of various biomarkers of chronic diseases via MXene modified electrochemical sensor for gaining a better understanding of their early diagnosis, disease progression, and risk assessment. Modification with MXenes improves the electrocatalytic functionality of the electrodes thereby improving their applicability in health and biomedical fields.

Abstract Nucleation is of great interest to materials scientists, physicists, and chemists studying fundamental scientific aspects of this phenomenon, as well as engineers working to develop glass-ceramics. Fundamental research in this field is indispensable for understanding the nature of the glassy state and the development of new products such as nanostructured glass-ceramics. However, experimental results on nucleation in inorganic oxide (mostly silicate) glasses and their theoretical interpretation in the framework of various mathematical models are still the subjects of significant debate. Difficulties during the early studies of nucleation partly arose from restrictions in experimental tools employed to study micron-sized or larger crystals, which cannot be directly applied to study nuclei of critical sizes or medium-range order in the parent glass, which are on a length scale of a few nanometers. Advanced tools, e.g., transmission electron microscopy, anomalous small-angle X-ray scattering, small-angle neutron scattering, X-ray absorption spectroscopy, Raman spectroscopy, nuclear magnetic resonance, advanced optical spectroscopy, together with computational modelings provide critical insight into the complicated and rapidly changing environments in which nucleation happens. The new findings from these sophisticated techniques and modeling approaches helps us evaluate hypotheses, modify available models, and develop new nanostructured glass-ceramics. Therefore, this paper reviews state-of-the-art solutions in instrumental and modeling analyses to measure and ultimately control nucleation. We propose adopting these tools and future impactful research in this exciting and challenging open field.

Abstract Over the past years, highly efficient conjugated polymers and small molecules have led to the development of organic photovoltaics (OPVs) as a promising alternative to conventional solar cells. Among the many designs, benzodithiophene (BDT)-based systems have achieved outstanding power conversion efficiency (PCE), breaking the 10% PCE barrier in the single-junction OPV devices. However, the precise molecular design of BDT-based materials to tune optical and electrochemical properties, morphology, and interaction between layers remains a challenge. At this point, computational chemistry provides an excellent option to supplement traditional characterization methods and, as a vital tool for designing new systems, understanding their structure–property relationship, predicting their performance, and speeding up OPV research. Hence, this review focused on advances in theoretical simulations of BDT-based OPVs during the last decade. First, a brief introduction of theoretical methodologies, including molecular dynamics simulations and quantum-chemical methods, is given. Then, selected examples of BDT-based materials that have shown great potential to generate high-efficiency devices were reviewed, considering DFT, deterministic, and stochastic methods. Finally, prospects and challenges are pointed out for the future design of improved OPVs.

Abstract The waste-to-wealth practice has evolved into the circular economy concept, in which every by-product is converted into a usable product, enabling the concept of zero-waste. As a result, research on converting wastes, particularly bio and agricultural wastes, into usable products is prioritized. Activated carbons are one of these products, which are derived through a variety of physical and chemical processes from agricultural and biowaste. These activated carbons have applications in various fields, including energy storage, catalysis, and water purification. However, the quality of this activated carbon is dependent on the bioresource's structure and chemical composition. As a result, many sources to produce activated carbon, including stems, wood, leaves, root, bark, fiber, flower, and seeds, have been identified and are being explored for their potential use as an electrode material for supercapacitors. Out of these sources, fiber from different bioresources shows improved performance as supercapacitor electrodes due to their higher cellulose and lignin contents. In this study, we systematically review various sources of activated carbon and their performance as supercapacitor electrodes. The electrochemical characterization methodologies used to characterize this fiber-based activated carbon are examined critically, and factors influencing its improved/poor performance are collated. Additionally, the most performing fiber-based sources of activated carbon for supercapacitor electrodes are identified, along with a future perspective.

Abstract Contemporary thermoelectric literature is rife with material structure-related terminologies like interfaces and grain boundaries, signaling the significance of these structures. Interfaces decide the characteristics of electronic and thermal transport and mechanical properties of polycrystalline and nano thermoelectric (TE) materials. Understanding the relationship between grain boundaries/interphase boundaries and property connections in materials is a key component of material design with desired characteristics and performance. It is now widely recognized that the microstructure of materials is intimately connected to their bulk properties. Accordingly, microstructure control and interface manipulation have emerged as critical topics in the field of materials science and engineering, particularly in thermoelectrics. This paper narrates recent breakthroughs in high-performance TE material design from the standpoints of interface structure and grain boundary manipulation. First, it provides a glimpse of strategies for thermal conductivity reduction through nano and microstructure control, embedded nanoinclusions, grain size reduction, and all-scale hierarchical architectures. It then deliberates on electron and phonon transport decoupling via coherent interfaces, matrix/precipitate electronic band alignment, and charge carrier filtering effects. It proceeds to review the recent results on TE properties of materials prepared with aforementioned strategies emphasizing Bi2(Te,Se)3 and (Bi,Sb)2Te3, SnSe, SnTe, Cu2Se, skutterudides, PbTe-based compounds, GeTe, polymer TE composites, and other materials. At the end, possible strategies for further enhancing zT are addressed. Graphical Abstract
