Abstract:
... Inspired by the phenomenon of water droplets hanging over rose petals, we propose a green interfacial self-assembly strategy to construct amphiphilic particles with controllable compartments for dual-drug encapsulation and controlled release. The method involves fabrication of “sticky” superhydrophobic materials, assembling superhydrophilic hydrogel beads with “sticky” superhydrophobic material in ...

Abstract:
... Aerosol control is a big revolution in production and use of submicronic particles. Developing a novel aerosol control technology in the area is the study objective of this paper. Attributing to the aerosol control potential in acoustics, a normal 16-sided aerosol aggregation chamber (pelletier dish) symmetrically installed with 16 poles of Helmholtz sound source (HSS) is successfully used to aggr ...

Abstract:
... Elaborate petals are present in many flowering plants lineages and have greatly promoted the success and evolutionary radiation of these groups. How elaborate petals are made, however, remains largely unclear. Petals of Nigella (Ranunculaceae) have long been recognized as elaborate and can thus be an excellent model for the study of petal elaboration. Here, by conducting detailed morphological, mi ...

Abstract:
... A widely held hypothesis in evolution is that adaptive specialization constrains the potential direction of future evolutionary change and thus may be irreversible, also known as Dollo's law. However, this hypothesis has long been subject to debate in evolutionary biology. Floral specialization is intriguing as it is usually linked to reproductive isolation and could affect speciation. Here, follo ...
