Summary: The use of an ultrathin hBN/PI layer on a commercial PP separator effectively suppresses dendrite growth in lithium-ion batteries and reduces active lithium consumption, while also providing good electrolyte wettability, mechanical strength, thermal conductivity, and high thermal stability. This modification results in stable battery capacity even after long cycling and at high temperatures.

Summary: The study found that in the vapour of lithium, severe cracking along the grain boundary can be observed on the surfaces of aluminium nitride ceramic samples. Possible corrosion failure mechanisms include the dissolution of aluminium nitride in aggregated lithium along the grain boundary. It is expected that high purity aluminium nitride and appropriate doping technology will provide better corrosion resistance under the same conditions.

Summary: In harsh marine environments, organic coatings have poor long-term protection performance. To address this issue, a triple-functional nano-pigment was developed, consisting of zinc oxide (ZnO) grown on boron nitride (BN) with polydopamine (PDA) as an interface layer (PDA-BN@ZnO nano-pigment). The results showed that the PDA-BN@ZnO nano-pigment exhibited improved corrosion inhibition and barrier properties, leading to excellent protective properties in the composite coating.

Summary: A novel molybdenum dioxide/boron nitride heterojunction composite was synthesized using a two-step calcination method, which showed prospective applications in metal corrosion protection. The total impedance values of MoO2/BN-1 and MoO2/BN-2 coatings increased to 314.7% and 163.6%, respectively, compared to an epoxy coating. This increase was attributed to the synergistic effects of physical barrier, electron transport blocking, and photo-induced corrosion protection. These stabilized molybdenum oxide heterojunctions with boron nitride carriers demonstrated feasibility for practical corrosion protection applications.

Summary: Boron nitride nanosheets (BNNSs) exfoliated from hexagonal boron nitride (h-BN) were functionalized with abundant surface hydroxyl groups through the attraction of oxygen radicals decomposed from di-tert-butylperoxide (TBP) induced by electron beam irradiation and then treated with piranha solution. The as-prepared covalently functionalized BNNSs possess reliable structural integrity and demonstrated enhanced compatibility and strong two-phase interactions with the polymer matrix, effectively promoting mechanical properties and breakdown strength of PVA/BNNSs nanocomposites.

Summary: This work investigated the effect of polytetrafluoroethylene (PTFE) on the tribological properties and corrosion resistance of epoxy/hydroxylated hexagonal boron nitride (EP/OH-h-BN) composite coatings. The results showed that the addition of PTFE significantly reduced the friction coefficient and wear rate, and increased the corrosion resistance of the coating. The improvement in coating properties was attributed to the synergistic strengthening effect of OH-h-BN and PTFE.

Summary: The incorporation of NZ/BNNS nanocomposites significantly improves the corrosion protection performance of WEP coating through passive and active protection mechanisms. The two-dimensional structure and impermeability of NZ/BNNS provide enhanced passive protection, while the release of corrosion inhibitors under acidic conditions contributes to active protection by adsorbing on the substrate.

Summary: Composite modulation in the superparaelectric state of the BTBZ-CT system is proposed as an effective strategy to achieve both NTCC and excellent energy storage performance in dielectric ceramics. The addition of BZ and CT to BT ferroelectrics can move the SPE state to the normal use temperature zone, resulting in enhanced NTCC characteristics and energy storage performance. Furthermore, intentional precipitation of CT at grain boundaries can refine the grain size, increase the bandgap, and strengthen the local electric field distribution, thereby enhancing the breakdown electric field.

Summary: This study analyzes the influence of calcia refractory purity on the properties of calcia crucibles. Higher purity calcia results in well-developed grains and improved hydration resistance, leading to better high-temperature strength and thermal shock resistance. In contrast, lower purity calcia crucibles exhibit inferior properties. Therefore, high-purity calcia is considered a potential refractory for manufacturing oxide crucibles.

Summary: To raise the operating temperature of Si-based ceramic matrix composites (CMCs), researchers have applied thermal/environmental barrier coating (T/EBCs) materials, typically rare earth silicates. However, the high thermal conductivity and the mismatch of thermal expansion have been major challenges in developing new materials that can offer thermal insulation and environmental protection to CMCs. In this study, entropy engineering was used to create a multicomponent equi-atomic single-phase pyro silicate with extremely low thermal conductivity and enhanced water vapor corrosion resistance. The research findings show the potential of high entropy disilicates in achieving ultra-low thermal conductivity and low weight loss in corrosive environments.

Summary: This study provides an atomic-scale description of the high-velocity impact of alpha-Al2O3 particles onto an alpha-Al2O3 substrate during Aerosol Deposition (AD). The results suggest that the crystal orientation plays a crucial role in both plasticity and damage of the nanoparticles. Impact velocity has a direct correlation with plasticity and fragmentation, but adhesion efficiency has only a marginal increase. The crucial element lies in the substrate's surface alterations caused by the fragments left on the substrate after impact.

Summary: This study characterized the long-term and repeated ablation properties of modified Cf/HfC-SiC composites with YB4-Al2O3-Si3N4 under an air plasma torch. The structural stability and viscosity of the oxide layer were found to affect the ablation resistance of the composites. By forming nano c-HfO2 grains and high-viscosity Al-Si-Y-O glassy phase, the structural stability of the oxide layer was improved, resulting in enhanced ablation resistance. However, the oxidation of Si3N4 led to the formation of NO, NO2, and excessive SiO2 glassy phase, which resulted in a porous structure and reduced the viscosity of the oxide layer. Therefore, the addition of Si3N4 decreased the ablation resistance of the composites.

Summary: In this study, solid solutions of xBi(Ni1/2Hf1/2)O-3-(1 - x)PbTiO3 (xBNH-PT) were synthesized to investigate their phase boundary behaviors and physical properties. The presence of a tetragonal-pseudocubic phase boundary and a spontaneous ferroelectric-relaxor transition at specific compositions were confirmed. The introduction of a tetragonal-pseudocubic phase boundary improved the piezoelectric properties and suppressed the spontaneous ferroelectric-relaxor transition.
