Technologies to Stabilize and Deliver RNA Strands

An organization is looking for technologies that can stabilize and deliver fragile RNA strands to plants and animals outside of a laboratory-controlled environment. The RNA strands may include dsRNA (double-stranded RNA) and shRNA (short hairpin RNA). A proposed solution must provide a method to make stable dsRNA or shRNA, and/or deliver the RNA to plants, animals, bacteria, fungi, or viruses at the organism level. The technology must maintain stability in a liquid, sprayable formulation, and have a shelf life of at least one or two years.

Lightweight Building System Eases Construction

A silicate-based, lightweight construction system features building blocks that are already covered by insulating material. After the concreting process, the formed, reinforced concrete tissue grid becomes load-bearing. There is no need for applying any subsequent heat or sound insulation.

Plastic Production System Controls Directional Forces and Tearing

To achieve exacting performance requirements, “Smittie” technology produces predictable bi-axial or mono-axial orientation in polymer materials. The system eliminates expensive equipment, curbs energy use, reduces the need for highly skilled labor, and shortens setup times.

Small-Droplet, Emissions-Control Nozzle Ensures Consistency

Macrospray® nozzles produce highly uniform spray patterns and droplet sizes (in the size range of 10-30μm Sauter Mean Diameter/SMD). The nozzles are created from digital tools with the flow features chemically etched into bonded substrates, resulting in a monolithic structure. Hydraulically smooth internal surfaces reduce flow losses. Nozzle passages, metering slots, spin chambers, and exit orifices are designed to minimize pressure drops.

Steel Alternative Features Higher Usability Strength

A new material offers a lighter weight and at least 30% higher usability strength compared to traditional steel. The equipment necessary for the production of the new technology is identical to equipment used for the manufacturing of conventional steel. It does not require other machinery, and the steel can be cast in molds as well as in closed continuous casting machines.

Controlled Delivery of Liquid

A customer seeks a range of technologies that will allow controlled delivery of liquid products over a wide viscosity range. Proposed technologies must work for liquids with low viscosity (such as floor cleaners) and/or very high viscosity (such as thick bleaches and body washes). Technologies will be evaluated based on added functionality to the product and optimization of delivery mechanism. Potential solutions include electro-sprays, ionizers, diffusers, piezotechnology, microfluidics, dosing caps, monodose/soluble pouches, orientable/ adjustable nozzles, and automatic spray heads. Technologies such as controlled dosing or automated dispensing are of high interest.

Spray Coating Systems

Current spray designs coat the exposed surface of the top layer of fibers, while fibers in the interior do not get treated. Fibers also move around when transported during processing, leading to exposure of untreated surfaces. An organization seeks novel technologies that can apply a spray coating to the entire surface area of a collection of fibers. New spray systems and designs must treat the underlying surface area of fibers. Spray systems that can be installed in a confined space are not required, but of additional interest. The invention must be compatible with water-based solutions.
