A device for producing a concrete includes a cement premixer for mixing a cement suspension, the cement premixer having an ultrasonic probe for preparing a cement suspension, a crystallization tank arrangement with the first crystallization tank, for increasing the early strengths of the concrete, and a concrete mixer for producing a concrete mixture from the premixed cement suspension, in particular with the addition of aggregates.

Methods and systems for fabricating synthetic source rocks with organic materials, for example, using high energy resonant acoustic mixing technology, are provided. An example method includes preparing one or more organic components including kerogen, mixing, by utilizing resonant acoustic waves, the one or more organic components with one or more inorganic components to obtain a mixture, and processing the mixture to fabricate a synthetic source rock. Another example method includes mixing one or more organic components and one or more inorganic components with a kerogen precursor as an organic binder to obtain a mixture including artificial kerogen and processing the mixture to fabricate a synthetic source rock. One or more mechanical or chemo-mechanical properties of the synthetic source rock can be characterized as one or more functions of the one or more organic components and the one or more inorganic components.

A unitary radome layer assembly is provided and includes a first nanocomposite formulation and a second nanocomposite formulation. The first and second nanocomposite formulations are provided together in a unitary radome layer with respective distribution gradients.

An optical window is provided and includes a core layer, a cladding layer and an electromagnetic interference (EMI) layer interposed between the core and cladding layers.

This can be a method of making a high strength composite reinforcing fiber using flat GO flakes coated on a conventional reinforcing fiber. This maintains some the flexibility of the fiber and aligns the flat graphene flakes along the surface of the fiber; this dramatically increases the strength of the fiber. It also allows bonding between overlapping flakes, in contrast to flakes being uniformly dispersed in a host material that is being reinforced and dramatically increases the strength of the host material.
