Ultrastable actinide endohedral borospherenes

Ultrastable neuroendocrine robot controller

The work of a simulated neuroendocrine controller with ultrastable neurons and glands is sketched and tested in terms of stability and adaptability. The artificial neurons connect to each other and to motors, while hormones produced by behaviour-related glands regulate their output. The ultrastable nature of the cells allows them to maintain their homeostasis by random reconfiguration of their ...

Ultrastable nanostructured polymer glasses.

Owing to the kinetic nature of the glass transition, the ability to significantly alter the properties of amorphous solids by the typical routes to the vitreous state is restricted. For instance, an order of magnitude change in the cooling rate merely modifies the value of the glass transition temperature (T(g)) by a few degrees. Here we show that matrix-assisted pulsed laser evaporation (MAPLE...

Ultrastable particle-stabilized foams.

Aqueous foams are important in a variety of different applications, ranging from food and cosmetics to oil recovery, blast mitigation, and fire extinguishing. Well-established and emerging applications that use foams as an intermediate structure to produce macroporous materials are also widely used in the field of engineering to fabricate thermal insulating materials and low-weight structures, ...

Ultrastable Oscillators for Space Applications

The requirements for high-stability ovenized quartz oscillators have been increasing in space applications. These devices provide attractive size, weight, power, and reliability for use in space missions; they also exhibit short-term frequency stability that rivals that of the best atomic-based signal sources. Symmetricom has delivered flight oscillators for the Lunar Reconnaissance Orbiter and...
