Synthesis of Lithium Lanthanum Titanate
Solid state batteries could potentially improve the characteristics of the conventional Li-ion batteries (capacity, charge/discharge rate, safety and sustainability) by replacing the organic electrolyte of the standard battery with a solid (crystalline, but also polymer and hybrid) electrolyte. One of the most promising solid electrolytes is Li3xLa2/3−xTiO3 (LLTO). A number of synthesis techniques have been employed for the preparation of the LLTO compounds. These can be divided on two subcategories: bulk material synthesis and nanostructured material synthesis. The first category contains primarily two methods: sol-gel method and the solid-state reaction method. Nanostructured materials are obtained by thin film deposition techniques and by electrospinning.

Perovskite-Type Oxides as Exsolution Catalysts in CO2 Utilization
Perovskite-type oxides (ABO3) are a highly versatile class of materials. They are compositionally flexible, as their constituents can be chosen from a wide range of elements across the periodic table with a vast number of possible combinations. This flexibility enables the tuning of the materials’ properties by doping the A- and/or B-sites of the base structure, facilitating the application-oriented design of materials. The ability to undergo exsolution under reductive conditions makes perovskite-type oxides particularly well-suited for catalytic applications. Exsolution is a process during which B-site elements migrate to the surface of the material where they form anchored and finely dispersed nanoparticles that are crucially important for obtaining a good catalytic performance, while the perovskite base provides a stable support. Recently, exsolution catalysts have been investigated as possible materials for CO2 utilization reactions like reverse water–gas shift reactions or methane dry reforming.

Electronic Structure and Chemical Bonding of Transition-Metal Monoborides
Boron presents an important role in chemistry, biology, and materials science. Diatomic transition-metal borides (MBs) are the building blocks of many complexes and materials, and they present unique electronic structures with interesting and peculiar properties and a variety of bonding schemes which are analyzed here. Comparisons between MB molecules along the three rows are presented, and their differences and similarities are analyzed. The bonding of the diatomic borides is also described. Three of them RhB(X1Σ+), RuB(X2Δ) and TcB(X3Σ−)  form quadruple σ2σ2π2π2 bonds in their X states. The RhB form quadruple bond also in two low-lying excited states.

Vibrational Coherence in MMLCT and MC Excited State
There have been significant advancements in the investigation of coherence-related phenomena in organic systems such as biological photosynthetic reaction centers. The d8 Pt(II) dinuclear complex or molecular aggregate with a metal–metal-to-ligand charge transfer (MMLCT) or metal-centered (MC) excited state was reported to show the vibrational coherence phenomenon in the intersystem crossing (ISC) process, due to the Metal–metal (M-M) interaction at excited state.

Metal Oxide Quantum-Dot-g-C3N4 Nanocomposites
Quantum dots and graphitic carbon nitride (g-C3N4) are essential elements in this science. In contrast to quantum dots, which have enormous potential due to their size-dependent bandgap tunability and effective charge carrier production, g-C3N4 has properties like chemical stability and a configurable bandgap that make it a versatile material for photocatalysis.

Theoretical Consideration of Molecular Helicenes and Their Properties
Some theoretical studies of properties of helicenes are considered. It was shown that helicenes are promising molecules for use as components of various nanodevices, due to the continuous π-system having a helical topology. Peripheral modifications of the edges make it possible to change the properties of helicenes over a wide range. The transition to polymeric helicenes is also considered.

Bio-Based Binder Development for Anodes in Lithium-Ion Batteries
The development of rechargeable lithium-ion battery (LIB) technology has facilitated the shift toward electric vehicles and grid storage solutions. This technology is currently undergoing significant development to meet industrial applications for portable electronics and provide our society with “greener” electricity. The large increase in LIB production following the growing demand from the automotive sector has led to the establishment of gigafactories worldwide, thus increasing the substantial consumption of fossil-based and non-sustainable materials, such as polyvinylidene fluoride and/or styrene-butadiene rubber as binders in cathode and anode formulations. Furthermore, the use of raw resources, such as Li, Ni, and Mn in cathode active materials and graphite and nanosilicon in anodes, necessitates further efforts to enhance battery efficiency. To foster a global sustainable transition in LIB manufacturing and reduce reliance on non-sustainable materials, the implementation of bio-based binder solutions for electrodes in LIBs is crucial.
