Polycyclic aromatic hydrocarbons (PAHs) commonly coexist in contaminated sites, posing a significant threat to ecosystem. Strains that degrade a wide range of substrates play important roles in bioremediation of contaminated environment. In this study, we reveal that Pseudomonas brassicacearum MPDS was able to remove 31.1% naphthalene of 500 mg/kg from soil within 2 d, while its relative abundance decreased significantly on Day 20, indicating its applicable potential in soil remediation . In addition to naphthalene, dibenzofuran , dibenzothiophene, and fluorene as reported previously, strain MPDS is able to degrade carbazole , phenanthrene , pyrene, and 2-bromonaphthalene. Moreover, NahA from strain MPDS has multi-substrate catalytic capacities on naphthalene, dibenzofuran, dibenzothiophene, phenanthrene, and 2-bromonaphthalene into dihydrodiols, while converts fluorene and carbazole into monohydroxy compounds according to GC–MS analysis. This study provides further insights into the exploration of soil remediation by strain MPDS and the mining of enzymes involved in the degradation of PAHs.

Boron nitride nanosheets (BNNS) were used to anchor bimetallic Pd–Fe nanoparticles for Suzuki–Miyaura coupling catalysts. The bimetallic nanoparticles were found to be core–shell in structure, and their formation was likely facilitated by their interactions with the BNNS. The Pd–Fe/BNNS catalysts were highly effective in representative Suzuki–Miyaura reactions, with performances matching or exceeding those of the state-of-the-art methods. Specifically, the superior catalytic activities were characterized by generally shortened reaction times, minimal Pd usage, excellent reusability of the catalysts and high or nearly quantitative conversion yields in a benign solvent system without the need for any special conditions, such as ligands and surfactants or inert gas protection. The obvious advantages of the Pd–Fe/BNNS over similar catalysts based on other supports, such as reduced graphene oxide (rGO), suggest that BNNS may be developed into a versatile platform for many other important catalytic reactions.

The residual tensile strain, which is induced by lattice and thermal expansion coefficient difference between upper perovskite film and underlying charge transporting layer, significantly deteriorates the power conversion efficiency (PCE) and stability of a halide perovskite solar cell (PSC). To overcome this technical bottleneck, herein, we propose a universal liquid buried interface (LBI) by introducing a low melting-point small molecule to replace traditional solid–solid interface. Arising from the movability upon solid-to-liquid phase conversion, LBI plays a role of “lubricant” to effectively free the soft perovskite lattice shrinkage or expansion rather than anchoring onto the substrate, leading to the reduced defects due to the healing of strained lattice. Finally, the inorganic CsPbIBr 2 PSC and CsPbI 2 Br cell achieve the best PCEs of 11.13 % and 14.05 %, respectively, and the photo-stability is improved by 33.3-fold because of the suppressed halide segregation. This work provides new insights on the LBI for making high-efficiency and stable PSC platforms.

In this paper, we designed and synthesized a novel TBET-based ratiometric fluorescent chemodosimeter, RH-Au, for Au3+. It was found that the probe RH-Au displayed highly selective, sensitive and naked-eye detection upon the addition of Au3+. The probe RH-Au can be used in the pH range 6.0–7.5 and the detection limit was determined to be as low as 2.91 nM (0.57 ppb). We also demonstrated a successful application of imaging Au3+ in living cells using RH-Au.

Healing charge-selective contact interfaces in perovskite solar cells (PSCs) highly determines the power conversion efficiency (PCE) and stability. However, the state-of-the-art strategies are often static by one-off formation of a functional interlayer, which delivers fixed interfacial properties during the subsequent operation. As a result, defects formed in-service will gradually deteriorate the photovoltaic performances. Herein, a dynamic healing interface (DHI) is presented by incorporating a low-melting-point small molecule onto perovskite film surface for highly efficient and stable PSCs. Arising from the reduced non-radiative recombination, the DHI boosts the PCE to 12.05% for an all-inorganic CsPbIBr 2 solar cell and 14.14% for a CsPbI 2 Br cell, as well as 23.37% for an FA 0.92 MA 0.08 PbI 3 (FA = formamidinium, MA = methylammonium) cell. The solid-to-liquid phase conversion of DHI at elevated temperature causes a longitudinal infiltration into the bulk perovskite film to maximize the charge extraction, passivate defects at grain boundaries, and suppress ion migration. Furthermore, the stability is remarkably enhanced under air, heat, and persistent light-irradiation conditions, paving a universal strategy for advanced perovskite-based optoelectronics.
