Summary: In recent years, there has been considerable interest in finding new drug-delivery materials. This study conducted a systematic investigation of the interaction between metformin and the surface of pristine B12N12 and group I metals (Li, Na, and K) encapsulation nanoclusters based on DFT calculations. The presence of alkali metals remarkably increased the absorption energy of MF-B12N12, and the addition of alkali metals led to a decrease in Egap and an increase in reactivity.

Summary: Graphene and hexagonal boron nitride have been widely used in water purification and environmental remediation. This study examined the adsorption of pesticides, antibiotics, and microcystin-LR on graphene and hexagonal boron nitride nano-systems. The results showed that the adsorption energy increases as the bond length decreases and the atomic partial charge increases. Hydrogen bonds played a crucial role in stabilizing the co-adsorption of pesticides/antibiotics and microcystin-LR on nano-systems. Graphene nano-systems exhibited excellent electron-accepting ability, making them suitable for sensor materials.

Summary: Nanotube-based drug delivery systems are highly promising for drug encapsulation due to their strong penetration capability and large internal volume. Molecular dynamics simulation revealed that cationic antimicrobial peptide cRW3 was encapsulated in biocompatible boron nitride nanotube through van der Waals interaction, with a decrease in vdW interaction strength over time. This study provides valuable insights into the encapsulation behavior of drugs in nanotubes and their potential applications in drug delivery.

Summary: To enhance the carrier mobility and suppress the intrinsic carrier density of graphene on a silicon dioxide substrate, a potassium-doped nano graphene intermediate layer was introduced. Electrical properties of the fabricated graphene field-effect transistors were measured, and the results showed a shift in the Dirac point and increased carrier density and mobility. The ionized potassium atoms in the intermediate layer shielded the electric force from the negatively charged impurities, resulting in improved field-effect mobilities.

Summary: Carbon aerogels are commonly used in composites to enhance thermal conductivity, but their low density and high porosity limit the amount of filler loading. Constructing carbon aerogels with a compact skeleton remains a challenge. This study proposes an in situ assembled and post-degas strategy to shrink expanded graphite aerogels, resulting in a densified structure that improves phonon/electron transfer and increases thermal conductivity in composites.

Summary: To address challenges in bacterial infection without using antibiotics, a new approach of ionic liquid (IL)-promoted simultaneous exfoliation and conjugation of boron nitride nanosheets (BNNSs) with ammonium dimolybdate (ADM) has been developed. The BNNS-IL-ADM provides sustained release of molybdenum ions, resulting in improved antibacterial efficiency against E. coli and S. aureus. The enhanced antibacterial performance is attributed to the synergistic effect between BN nanocarrier and bioactive ADM, as well as the nanoconfinement capability of BNNS-IL-ADM.

Summary: Portland cement-based nanocomposites with low volume fractions of hBN nanoplatelets were prepared successfully through exfoliation and functionalization of hBN using ball milling and sonicated-assisted dispersion. AFM and Raman analysis were utilized to evaluate the properties of hBN nanoplatelets, while FTIR was used to identify the functional groups on functionalized hBN. The results demonstrated that the functionalization process successfully achieved few-layer thicknesses of hBN nanoplatelets, leading to suspensions with high colloidal stability. The interaction between hydroxyl and carboxyl groups on the hBN surface and Ca2+ ions of CSH improved the load-transfer efficiency, resulting in significant enhancement in flexural strength, compressive strength, Young's modulus, and fracture energy of the hBN reinforced cementitious composites.

Summary: Ultrahigh-temperature ceramics (UHTCs) are highly hard and resistant to oxidative ablation, suitable for hypersonic environments. However, their low fracture toughness limits their use. In this study, zirconium diboride was sintered with high aspect ratio boron nitride nanotubes (BNNTs) to improve fracture toughness. Plasma functionalization effectively disperses the BNNTs in UHTC, increasing the fracture toughness of the UHTC composite.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
