Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

The motion of a singular vortex near an escarpment [PDF]

, 2001
McDonald (1998) has studied the motion of an intense, quasi-geostrophic, equivalent barotropic, singular vortex near an infinitely long escarpment. The present work considers the remaining cases of the motion of weak and moderate intensity singular ...

An experimental investigation on elliptical instability of a strongly asymmetric vortex pair in a stable density stratification [PDF]

Nonlinear Processes in Geophysics, 2006
We investigate the elliptical instability of a strongly asymmetric vortex pair in a stratified fluid, generated by the acceleration and deceleration of the rotation of a single flap.

Biomimetic Core–Shell Liposome Nanoparticles Deplete Lipoproteins and Enhance the Purity of Extracellular Vesicles from Human Blood

Advanced Functional Materials, EarlyView.
Lipoprotein‐mimicking nanoparticles (SL‐NPs), comprising Fe3O4@SiO2 cores coated with liposomal bilayers, selectively capture lipoproteins through protein corona formation. The resulting SL‐NP‐lipoprotein complexes can be removed by low‐speed centrifugation, thereby enhancing the purity of small extracellular vesicles (sEVs) isolated from human serum ...

ATP‐Mediated Bidirectional Communication Between Natural and Artificial Cells for Controlled Bioreactions

Advanced Functional Materials, EarlyView.
Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...

Efficient approach for generating vortex sources with arbitrary orbital angular momentum in acoustic experiments

New Journal of Physics
In theoretical research framework of acoustics or optics, how to provide stable and efficient experimental vortex sources with arbitrary orbital angular momentum (OAM) (especially with larger OAM) is a highly challenging research topic.

Three-dimensional characteristics of separation vortex generated by crossing shock/boundary layer interaction

AIP Advances
Three-dimensional shock/boundary layer interactions (SBLIs) in the hypersonic inlet generate the separation vortex, which affects the flow uniformity of the inlet and can even cause the inlet to unstart.
