Summary: With the development of information technology, the demand for high-performance thermal conductive polymer-based materials used in microelectronic devices is increasing rapidly. However, the dispersion of fillers in composites often fails to form continuous heat transfer pathways due to interfaces, resulting in reduced thermal conductivity. In this study, boron nitride nanosheets (BNNS) were confined in carbon nanofibers using electrostatic spinning, forming a fibrous carbon-boron nitride hybrid skeleton that was combined with silicone rubber to create an elastic composite film. The effects of BNNS content on the hybrid skeleton morphology and composite conductivity were investigated. The study found that the hybrid skeleton consisted of continuous long-stacked carbon fibers with high intrinsic thermal conductivity, and the BNNS were tightly stacked, confined, and oriented along the fibers. The maximum thermal conductivity of the composite film was 4.09 W m-1 K-1, about 16 times higher than that of pure PDMS. A double thermal conductive network mechanism was proposed, where two thermal pathways were formed by overlapped BNNS and carbon fibers. The optimal thermal conductivity was achieved when the two pathways composited together through spinning and carbonization. The study also prepared composite films with vertically aligned hybrid fibers. This work provides an essential and innovative strategy for the preparation of high thermal conductivity composites.

Summary: This paper discusses the optoelectronic properties of metal halide perovskites as an attractive photovoltaic material and focuses on the losses induced by nonradiative recombination processes in the device stack. The study reveals that nonradiative recombination processes at interfaces are more dominant than those within the bulk of the perovskite absorber, but there is still room for improvement in suppressing bulk nonradiative recombination. General routes for suppressing recombination processes within the bulk and at interfaces are also discussed.

Summary: In this study, the optimal timing for biliary drainage in patients with acute cholangitis (AC) with different severity grades and organ dysfunctions was investigated. The results showed that early biliary drainage could decrease in-hospital mortality in certain specific situations, but it also increased hospital length of stay and costs. Neurological, respiratory, renal, and cardiovascular dysfunctions, hypoalbuminemia, and malignant obstruction were significantly associated with in-hospital mortality. Different drainage timings achieved better outcomes for different disease conditions and dysfunctions.

Summary: Four types of polymers were selected as additives to improve the mechanical properties of aramid nanofiber (ANF) film. The results showed that all of these polymers enhanced the strength, elongation, and toughness of the ANF film. The TPU and PAM with amide structures formed ordered hydrogen bond networks and significantly improved the strength, while PAA and PVP showed strong enhancing capacities on toughness. This study also revealed the weak enhancing ability of nonpolar polymer PS on the mechanical properties of ANF film due to poor interfacial compatibility and phase separation.

Summary: Solvothermal techniques are commonly used for exfoliating two-dimensional materials, but the mechanisms behind the formation of these nanomaterials are not well understood. This study revealed the dissociation of hexagonal boron nitride (h-BN) during solvothermal exfoliation, leading to the formation of B(OH)3, NH4B5O8 center dot 4H2O, and (NH4)2B10O16 center dot 8H2O. The size of the resulting boron nitride nanosheets (BNNSs) was found to increase in specific solvents, suggesting different dissolving abilities of the solvents. The inclusion of lithium chloride (LiCl) and cetyltrimethylammonium bromide (CTAB) enhanced the dissociation process and yielded BNNSs with smaller lateral sizes.

Summary: Industrial wastewater affects public health and water ecosystems by causing water pollution, including heavy metal ions and organic matter. Therefore, the development of adsorbents with multiple adsorption effects is crucial for efficient adsorption. In this study, a composite aerogel called ZIF-8@CPA was designed and fabricated by assembling porous zeolitic imidazolate framework-8 (ZIF8) onto cellulose nanofiber (CNF)/poly(vinyl alcohol) (PVA)/aramid nanofiber (ANF) composites. The ZIF-8@CPA composite aerogel exhibited good physical properties and optimal adsorption performance at 20% ZIF-8 content, achieving high adsorption capacity for heavy metal ions and conforming to a pseudo-second-order kinetic model.

Summary: Rational design and modification of the buried interface towards high performance perovskite solar cells (PSCs) were achieved by using guanidinium passivators with multiamine substitutions. The binding geometry of the highly polarized imine moiety in the passivators was found to dominate the passivation effect on the SnO2 surface, resulting in reduced trap density and nonradiative recombination. The PSCs with buried passivators exhibited a champion power conversion efficiency of 24.4%, an advanced open-circuit voltage of 1.197 V, and a prolonged lifetime over 90% of the initial efficiency after 900 hours in ambient conditions.
