Abstract: An apparatus for the manufacture of synthetic diamonds includes a pressure vessel having a chamber therein, and a body located in the chamber. The pressure vessel and the body are formed of materials having different coefficients of expansion. The coefficient of expansion of the body is greater than the coefficient of expansion of the pressure vessel. The pressure vessel is formed from a material having a melting point in excess of 1327° C. and capable of withstanding a pressure of at least 4.4 Gpa at a temperature of at least 1327° C. The chamber is configured to receive the body, and a carbon source, the apparatus further comprising a heating means configured to heat at least the body to a temperature at least of 1327° C. The coefficient of expansion of the body is selected such that upon heating thereof to at least 1327° C. the pressure exerted on the carbon source is at least 4.4 Gpa.

Abstract: The present invention relates to new products and processes for making and using hop extract products comprising hop oils present in amounts between about 6 mL/100 g to about 40 mL/100 g, or more. The oil enriched hop extracts of the present invention also contain higher proportions of oil relative to other hop components typically found in hop extracts. Production of the oil enriched hop extracts may comprise a partial or a first extraction of hop materials. In one preferred embodiment, such extraction may occur under pressures of 1700 psi to about 3700 psi for less than three hours. The enriched oil extracts of the present invention can be used to produce beers having enhanced aroma and flavor profiles. The present invention also relates to products and processes for making and using second extractions of hop materials comprising alpha acids present in amounts of, for example, about 50% to about 70% (w/w).

Abstract: The invention relates to a method for obtaining synthetic diamonds from sucrose, and to a device for carrying out said method, the method comprising: introducing sucrose or a solution of water and sucrose into a hermetic capsule without air, which is surrounded by an external container that keeps the volume of the capsule constant during the entire process; increasing the pressure inside the capsule by breaking down the sucrose inside the capsule, either by increasing the temperature or by combining the sucrose with sulfuric acid, until the carbon resulting from said pressure conditions of the capsule is transformed into diamond; and controlling the pressure generated inside the capsule, using containing means that apply pressure externally around the container of the capsule. In addition, extra carbon is added, increasing the dimensions of the diamond.

Abstract: The present disclosure relates to a system and method for synthesis of condensed, nano-carbon materials to create nanoparticles. In one embodiment the system may have a source of liquid precursor, a flow control element and a shock wave generating subsystem. The flow control element is in communication with the source of the liquid precursor and creates a jet of liquid precursor. The shock wave generating subsystem drives a shock wave through at least a substantial portion of a thickness of the jet of liquid precursor to sufficiently compress the jet of liquid precursor, and to increase a pressure and a temperature of the jet of liquid precursor, to create solid state nanoparticles.
