Soap based thermal insulation as an environmental alternative to petroleum based thermal insulation
… an alternative to petroleum based thermal insulations, by using natural and recycled materials. The methodology used is centered on the use of the basic ingredients of waste animal fats, waste oils and a potash derived lye mixture, combined to create a crude soap. This soap is aerated to …

Biomass Characterization and Insulation Optimization Studies
… used as naturally sustainable alternatives to insulation materials. Barley grains and oak leaves, straw, and jute are collected, and crushed into powders/ chopped pieces. The physical characteristics are measured to characterize each powder. The biomass powder reinforced composites are …

A Novel Switchable Thermal Insulation Technology
Switchable thermal insulation, in the form of an opaque panel that alternates between thermally conductive and insulated states, can be an effective means of regulating the thermal environment by selectively transferring heat between the indoor and outdoor environments. Pioneering work has been …

Thermal properties of advanced aerogel insulation
… windows, under doors, etc and blowing more insulation into the attic. Deep retrofits are those that involve costly renovation and typically include adding insulation to the walls and replacing windows. A new, easily installable, inexpensive, and thin insulation would move insulating the …

Phosphorylation based insulation devices design and implementation
… presents the analysis of a phosphorylation based insulation device implemented in Saccharomyces cerevisae and the minimization of the retroactivity to the input and retroactivity to the output of a single cycle phosphorylation device by means of optimal substrate and phosphatase concentration …

Truss core sandwich panels with compacted aerogel insulation
… are often used in a granular form in thermal insulation, with some increase in their thermal conductivity, to about 24 mW/in-K, from the air between the granules. Here, we describe a technique for compacting granular silica aerogel that reduces the thermal conductivity to 13 mW/m-K, roughly …

Retroactivity, modularity, and insulation in synthetic biology circuits
A central concept in synthetic biology is the reuse of well-characterized modules. Modularity simplifies circuit design by allowing for the decomposition of systems into separate modules for individual construction. Complex regulatory networks can be assembled from a library of devices. However, …

Insulation of Processes Across the Hemispheres Modulates Attentional Processes
… some factors that may affect the efficiency of insulation. In a spatial selective attention task one of two hierarchical letters, presented one in each visual field, was to be identified at a pre-assigned level (i.e., global or local). A first experiment showed that the likelihood of insulation …
