Summary: The study used DFT calculations to investigate the interaction between B12N12 and Al12N12 nano-cages with ALP, revealing that the complex formed between B12N12 and ALP is more stable and its stability increases in water. Effective charge transfer was observed from ALP's nitrogen atoms to the boron atoms of the nano-cages, with interactions between Al12N12 and ALP driven mainly by non-covalent forces, while ALP/B12N12 interactions were primarily electrostatic and partially covalent.

Summary: The study investigated the hydrodesulfurization of thiophene compounds using CoMo/gamma-Al2O3 and CoMo/gamma-Al2O3-Nb2O5 catalysts. The addition of Nb2O5 showed positive effects on enhancing the catalyst's surface area and acidity, leading to improved hydrodesulfurization activity for thiophene, 2-ethylthiophene, and benzothiophene. Additionally, a mutual inhibition effect was observed between sulfur compounds in the reaction, with Nb2O5 mitigating this inhibition effect to a certain extent.

Summary: The electronic and optical properties of ultra-small carbon and boron nitride nanotubes were investigated using three different density functional methods. The hybrid functional YS-PBE0 performed the best for calculating the band gap of boron nitride nanotubes, while the PBE and TB-mBJ functionals showed smaller errors for carbon nanotubes. The dielectric function was anisotropic for all nanotubes, with higher static refractive index in the carbon nanotubes and an inverse correlation with diameter.

Summary: This study elucidated and characterized the interaction of heavy metals like nickel, cadmium, and lead with (10,0) zigzag boron nitride nanotubes using first principle method within the density functional theory. The findings showed that the adsorptions of nickel and cadmium are favorable, while the adsorption of lead is not favorable. Nickel has the lowest binding energy and induces major modifications on the electronic structure, while cadmium and lead trigger changes in the magnetism of the nanotube.

Summary: The research found that Cr/BNNT single atom catalyst can simultaneously remove N2O and CO gases with high efficiency and application prospects. In the reaction, the Cr atom acts as an electron bridge through its 3d orbital, playing an important role in activating N2O and CO molecules. Meanwhile, BNNT support with high redox stability can act as an electron reservoir, aiding the overall reaction.

Summary: To investigate the characteristics of certain materials, we employed density functional theory (DFT) with specific parameters. We focused on studying Boron Nitride (BN) cage and BN complexes with super salt (OLi3NO3) and analyzed their response mechanisms using various techniques. The doped complexes showed improved electron transport properties compared to pure BN surface, and the designed complex BN@H2 demonstrated outstanding nonlinear optical (NLO) properties.

Summary: The sensing functions of an iron-doped boron nitride nanocone (FBN) towards acetaminophen and its thio/thiol analogs were investigated using density functional theory calculations. Formation of FBN-ACM complexes was observed through keto/thio and enol/thiol interactions with the Fe-doped region of FBN. The study found significant variations in electronic conductance and recovery time, indicating the potential of FBN as a sensor for ACM and its analogs.

Summary: This study investigates boron nitride nanotubes (BNNTs) synthesized by the high temperature-pressure (HTP) method and compares their properties after different purification processes using advanced electron microscopy techniques. The results show that BNNTs of higher purity form small, ordered domains at lower concentrations and defects do not prevent their nematic alignment. Cryogenic electron microscopy provides direct-imaging evidence of the BNNT liquid crystalline phase, suggesting the potential for the fabrication of highly ordered BNNT-based macroscopic assemblies through liquid-phase processing.

It has structural stability and low cohesive energy, indicating high synthetic possibility. Its mechanical and electronic properties are investigated, and the stacking form of the 3D bi-BN system is discussed. Its physical properties can be manipulated by external stress, showing potential for further development.

Summary: In this study, we investigated the oxidation stability of h-BN by examining different modifications of its structure using an atomistic thermodynamics approach. It was found that oxygen is deposited on the surface of h-BN as peroxide without dissociation up to temperatures of about 1700 K. At higher temperatures, oxygen tends to be incorporated into the lattice of h-BN, except when defects are present. The electronic and magnetic properties of the oxidized h-BN were also analyzed.

Summary: The study reveals that under pressure, strong electrostatic repulsion between π electrons and in-plane sp(2) electrons in graphitic carbon nitride materials may distort intralayer phonon vibrations and affect the increase in resistivity. Moreover, the different pressure responses in resistance of C2N and C3N are attributed to their distinct π electron distributions.

Summary: Novel N-doped ordered mesoporous carbon hollow spheres (N-OMCHS) were successfully synthesized using two different nitrogen sources, N1-OMCHS and N2-OMCHS, and their catalytic activity towards the Oxygen Reduction Reaction (ORR) in alkaline media was evaluated. N2-OMCHS showed the best performance for the ORR, but surprisingly, N1-OMCHS improved in performance after Accelerated Degradation Test (ADT) and exhibited better stability compared to N2-OMCHS. X-ray photoelectron spectroscopy results indicated chemical modifications of nitrogen species on the surface, leading to enhanced ORR performance. Therefore, N-OMCHS are considered as potential non-platinum electrocatalysts for Anion Exchange Membrane Fuel Cells (AEMFC) cathode applications.

Summary: AlxCoCrFeMnNi high-entropy alloys with different aluminum concentrations were synthesized and sintered using different methods. The presence of FCC, BCC, and B2 ordered phases was observed regardless of the sintering method. The morphology of the BCC phase varied with different sintering methods, affecting the hardness values. Different carbides were identified depending on the sintering method used. The HFIHS + CS method resulted in higher densification than the CS method.

Summary: In this study, the Li-silicene system was studied using density functional theory. The electronic and vibrational properties of lithiated silicene were calculated. It was found that there is a dynamically stable intermediate state at a lithium concentration of 0.38, and a metal to semiconductor transition occurs at lithium concentrations of 0.33 and 0.46. Additionally, vacancies in silicene significantly decrease its mechanical properties.

Summary: In this study, chitosan-poly(3-hydroxybutyrate) (CS-PHB) blend films with high apparent piezoelectric coefficient were reported. The structure of CS-PHB blend films, including the dielectric, polarization, and apparent piezoelectric properties, as well as their dependencies on composition, was investigated. The results suggest that the synergistic effects of piezoelectricity and electrostriction contribute to the high value of the apparent piezoelectric coefficient obtained in the blend film.
