Hypervirulent Klebsiella pneumoniae (hvKP) has emerged as a novel variant of K. pneumoniae, exhibiting distinct phenotypic and genotypic characteristics that confer increased virulence and pathogenicity. It is not only responsible for nosocomial infections but also community-acquired infections, including liver abscesses, endophthalmitis, and meningitis, leading to significant morbidity and mortality. HvKP has been reported all over the world, but it is mainly prevalent in Asia Pacific, especially China. Moreover, hvKP can acquire carbapenemase genes resulting in the emergence of carbapenem-resistant hypervirulent K. pneumoniae (CR-hvKP), which possesses both high virulence and drug resistance capabilities. Consequently, CR-hvKP poses substantial challenges to infection control and presents serious threats to global public health. In this paper, we provide a comprehensive summary of the epidemiological characteristics, virulence factors, and mechanisms underlying carbapenem resistance in hvKP strains with the aim of offering valuable insights for practical prevention strategies as well as future research.

As a spontaneous solar-thermal energy conversion technology with high photothermal efficiency, solar-driven interfacial evaporation has attracted enormous attention. However, considering the inadequate light illumination most of the time in a day and the expensive light-concentrating facilities, achieving high energy conversion efficiency under low solar flux is in great demand. In this work, we develop a broadband solar absorber based on graphene hybrid aerogels with MoS2 nanoflower decoration and nitrogen doping (MNGA). Synthesized via a two-step hydrothermal method, the porous MNGA shows self-floating ability, good thermal insulation, and a strong solar absorption of ≈93% in the visible to near infrared range. The nanoflower-like MoS2 decoration and nitrogen doping modulate the surface hydrophilicity jointly. Compared to nitrogen-doped GA , MNGA shows a reduced surface hydrophilicity, while still ensuring good wettability for water transport. Under low solar flux (0.3–1.0 sun), MNGA presents a high energy conversion efficiency (89.7–96.9%) and excellent cycling performance. It is endowed with good salt resistivity and recycling stability, maintaining an average efficiency of 96.6% under 1 sun illumination and stable performance during 10-cycle evaporation tests. These hybrid aerogels with outstanding photothermal performance, self-floating ability, salt resistivity, and durability offer a potential approach to realize water purification and desalination in daily life.
