Summary: The study investigated the impact of electron beam irradiation on the atomic-level features of doped lithium transition metal oxide cathodes using the high-precision technique of STEM-EDX. It was found that the susceptibility of the materials to electron beam irradiation significantly depends on the energy of the accelerated electrons, with higher energy beams causing structural changes. The addition of a small amount of Ti doping into the material increased its tolerance to electron beam irradiation, while STEM probe-based monitoring at atomic resolution proved to be a potential indicator of battery stability and life.

Summary: A cadmium-based metal-organic framework (CdMOF) with a cuboid-shaped morphology was synthesized at ambient temperature. The CdMOF exhibited electroactivity and a specific capacitance of 647 F g-1 at 4 A g-1 with a retention of approximately 78% over 10,000 successive cycles without any binder. By exploring different electrolytes, NaOH showed a higher capacitive response due to its combined effect of ionic and hydrated ionic radii. An asymmetric supercapacitor (ASC) device was fabricated using CdMOF as the positive electrode and activated carbon (AC) as the negative electrode, which successfully powered a LED bulb.

Summary: This paper focuses on the study of titanium silicate's adsorption capacity for Ba2+ cations. Titanium silicate can be synthesized from waste produced in titanium production, which is beneficial for environmental protection. The surface area of the adsorbent was determined using low-temperature N2 adsorption-desorption isotherm. The elemental composition of titanium silicate was analyzed using XRF and EDS. The study investigated the factors affecting the adsorption values of Ba2+, including duration of interaction, equilibrium concentration, and solution acidity. The experiment measured a maximal adsorption value of 144 mg/g for Ba2+ ions. The adsorption mechanism was determined to be physical adsorption with an adsorption energy value of 0.947 kJ per mole, calculated using the D-R equation. This study has potential implications for adsorbent regeneration.

Summary: MXenes are two-dimensional materials with high conductivity, redox activity, and compositional diversity and have shown great potential in energy storage applications. However, their energy storage capability is limited by a narrow electrochemically stable potential window. Transition metal oxides (TMOs) have high redox activity but suffer from poor cyclability and rate performance. Combining MXenes with TMOs can enhance the charge storage capacity of MXenes while improving the cyclability and rate performance of oxides, making MXene/TMO heterostructures promising for energy storage.

Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
