Energy dependence of He-ion-induced tungsten nanofuzz formation at non-normal incidence angles
Nuclear Materials and Energy, 2017 We report measurements of He-ion-beam induced tungsten nanofuzz formation for normal and non-normal incidence angles in the energy range 218eV–10keV. At 218eV, the fuzz tendrils are fine and grow randomly away from the interface in the direction of the ...

Combining the Pitcher and Lotus Plant: Supericephobic and Superhydrophobic Silicone Films
Advanced Science, Volume 13, Issue 23, 23 April 2026.Based on bench‐top nanomolding of polydimethylsiloxane (PDMS) with optimized silicone oil content, we developed hierarchically structured silicone films by essentially combining the properties of the lotus and pitcher plant; particularly we are able to achieve water contact angle as high as 171° and ice adhesion strength as low as 11.5 kPa (i.e ...

Morphologically Chiral Crystals From Achiral Dyes
ChemistryEurope, Volume 4, Issue 4, April 2026.Twisted crystals with varied and beautiful morphology appear when grown from solution for a dye family—the diketopyrrolopyrroles whose structure is shown in the picture. The morphology depends on the R group, where all twisting arises from an auto‐deformation mechanism of the growing crystals that unwind as they get thicker.

Transcriptomic regulation of juvenile-to-adult vegetative phase transition in grapevine
OENO OnePlants go through two distinct stages in their vegetative phase, with the juvenile stage being characterised by a lack of maturity to respond to flowering induction stimuli and the adult stage marked by the presence of this capacity.

Interfaces and the edge percolation map of random directed networks
, 2007 The traditional node percolation map of directed networks is reanalyzed in terms of edges. In the percolated phase, edges can mainly organize into five distinct giant connected components, interfaces bridging the communication of nodes in the strongly ...
