Highly dispersed SiO/BiVO hybrid pigments with a spherical structure and high near-infrared (NIR) reflectance have been successfully fabricated by a facile sol-gel method followed by calcination. The dispersed and uniformly spherical particles of the hybrid pigments were caused by the support provided by SiO microspheres, and their color was adjusted via the band-gap energy, which was changed with the incorporation of SiO microspheres. The SiO/BiVO-3 hybrid pigment presented higher yellow hues (b* = 91.42) and more dispersed spherical particles than other as-prepared hybrid pigments and commercially available BiVO-based yellow pigment. This strategy could save 72 wt% resource of BiVO while yielding the same amount of yellow pigment with high color performance. Therefore, the prepared hybrid pigments not only dramatically decreased the cost of expensive pigments, but also saved scarce resources and reduced environmental pollution. In addition, the SiO/BiVO-3 hybrid pigment also presented high NIR reflective performance, which demonstrated that it would be a favorable candidate for colorful NIR reflective pigments with wide applications in heat insulation.

A novel aerobic marine bacterium, FRT2, isolated from surface water of a fishing port in Fukui, Japan, was characterised based on phylogenomic and phylogenetic analyses combined with classical phenotypic and chemotaxonomic characterisations. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FRT2 clustered with genus Leeuwenhoekiella. Closest relatives of FRT2 were Leeuwenhoekiella palythoae KMM 6264 and Leeuwenhoekiella nanhaiensis G18 with 16S rRNA gene sequence identities of 95.

Carbon-based polymer composites are widely used in wearable devices due to their exceptional electrical conductivity and flexibility. However, their temperature-dependent resistance variations pose significant challenges to device safety and performance. A negative temperature coefficient (NTC) can lead to overcurrent risks, while a positive temperature coefficient (PTC) compromises accuracy.

Introduction: Recent findings show that visible light, particularly blue light, stimulates melanogenesis in human skin, though the underlying mechanisms remain debated. This study aimed to determine the cell damage threshold of non-ionizing blue light on keratinocytes while preserving their ability to stimulate melanogenesis.
Methods: Human keratinocytes (N = 3) and melanocytes (N = 3) were isolated from skin samples of varying Fitzpatrick skin phototypes and irradiated with blue light (λpeak = 457 nm) and UVA light (λpeak = 385 nm).
