Method for Improving the Quality and Quantity of Offspring in Mammals (RFT-494)

Scientists at NDSU have developed a method for predicting and/or confirming the success of pregnancy and/or litter size in mammals as well as devices for field testing of mammal samples for pregnancy success and reproduction prosperity (fecundity).  Measuring hematocrit levels or blood oxygen saturation near the time of insemination of a mammal can indicate the likelihood of a successful pregnancy and also predict litter size.  These methods can also be used to confirm a successful pregnancy sooner than other methods.

Novel Monomers from Biomass (RFT-478)

The majority of biomass polymers, when broken down into their constituents, consist of cellulose derived sugars of 5 or 6 carbon atoms and lignin-derived aromatic building blocks. These building blocks are relatively highly oxidized and thus, without further chemical conversion, are not well-suited for fuels and chemicals. Scientists at NDSU have recently invented novel methods for the conversion of renewable resources to feedstock chemicals. The lignin and cellulose degradation products are converted to higher quality monomers through certain chemical reactions for use in polymer synthesis.

Biodegradable Soil Sensors that can be "Planted" with a Seed Mixture (RFT-428)

Scientists working at NDSU are developing biodegradable sensors capable of directly monitoring and reporting the soil environment in which they are placed. The sensors are constructed by using NDSU’s patent-pending “direct write” electronic printing techniques to print circuit and antenna patterns directly onto renewable, bio-based materials. The circuit patterns are printed with trace amounts of metallic materials such as aluminum that are safe for the soil when the sensors naturally biodegrade over time.

Removal and Recovery of Phosphate from Water Bodies and Reuse as a Fertilizer (RFT-419)

Scientists at NDSU have developed biodegradable iron-containing alginate beads that remove phosphorus from water, and can then be beneficially reused to provide Phosphate fertilization. As a result, this dual-use technology can be used to clean water bodies that are eutrophic due to excess phosphorous, then use the phosphorous for fertilization in agricultural, nursery, and greenhouse settings where phosphorus is a limiting nutrient.

Vegetable Oil-Based Polymers for Nanoparticle Surface Modification (RFT-413)

The extremely high surface area of nanoparticles provides many advantages over conventional particles with dimensions in the micron scale. For a variety of applications, it is necessary to suspend the nanoparticles in a liquid medium. Researchers at NDSU have developed a new plant-oil-based polymer technology focused on the application of nanoparticle suspension in water.

DNA Encoding an Avian E. Coli ISS and Avian E. Coli ISS Polypeptide (RFT-21)

Scientists at North Dakota State University have cloned and sequenced the iss (increased serum survival) gene from virulent avian Escherichia coli strains and expressed its encoded ISS polypeptide sequence. This has enabled them to conduct studies in understanding the gene’s potential and devise strategies to detect and control the colibacillosis infection that the gene is believed to cause.
