Passive water control at the surface of a superhydrophobic lichen [PDF]
, 2011 Some lichens have a super-hydrophobic upper surface, which repels water drops, keeping the surface dry but probably preventing water uptake. Spore ejection requires water and is most efficient just after rainfall.

Passive thermal control systems in spacecrafts
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2023 A spacecraft is a vehicle designed for accomplishing a mission for military, scientific and commercial purposes. While designing a spacecraft, scientists face some challenges, one of which is the design of a thermal subsystem. A spacecraft is exposed to internal and external thermal loads during its lifetime.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Passively Controllable Smart Antennas [PDF]
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010 We recently introduced passively controllable smart (PCS) antenna systems for efficient wireless transmission, with direct applications in wireless sensor networks. A PCS antenna system is accompanied by a tunable passive controller whose adjustment at every signal transmission generates a specific radiation pattern.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
