Co-Developer: BUNTING-DuBois

Permanent magnets, a key component for electrification, are crucial for a sustainable green economy. However, there is a disconnect among presently available permanent magnets as they often fit either high- or low-energy applications. The Cerium Gap Magnet represents the next generation of permanent magnets with affordable pricing and performance that will satisfy a wide range of middle energy applications. The magnet can be processed effectively in the U.S., making it less supply-dependent, and it does not use any critical rare earths. This magnet frees up critical neodymium and dysprosium from their current middle energy applications, mitigating the existing supply risks and accelerating the transition to green energy.

DuPont Styrofoam Plazamate XR Extruded Polystyrene Foam with 30% Higher Thermal Resistivity

DuPont de Nemours, Inc., Water and Protection, Performance Building Solutions

Styrofoam Brand Plazamate XR has the highest thermal resistance (R) per inch of any extruded polystyrene (XPS) roofing insulation (6.7 R/in). This means 30% more thermal resistance in every inch of its thickness compared with typical XPS insulations. This reduces assembly thickness and increases design flexibility while meeting critical needs in height-constrained roof replacement and new construction conditions that require XPS’ moisture resistance. With Plazamate XR, fewer layers and an overall lower volume of insulation may be required to achieve the code-mandated roof insulation (R-values), resulting in labor savings, shipping and handling less material, and waste reduction.

PHAs-based bioplastic: an eco- friendly alternative to mitigate marine plastic pollution

PHAs (Polyhydroxyalkanoates)-based bioplastics are one of the most promising alternatives to traditional petroleum plastics and they are aliphatic polyesters produced from renewable feedstock. Compared to other plastics, PHAs bioplastics has good marine biodegradability and are synthesized directly via fermentation of a carbon substrate inside a microorganism. A variety of PHAs with different struct ures are produced depending on the types of bacterial species and carbon source provided.

NARI (National Atomic Research Institute) uses high-throughput screening system, micro-fermenter and ton-scale fermenters with competitive PHAs fermentation performance to speed up R&D progress. The cell dry weight (CDW) is 65.2 g/L with stable PHAs content of 43.2%, which is better than the results of international literature.

PHAs bioplastics have various applications in industries such as food packaging, agriculture (e.g., mulching film) and medicines (e.g., wound grafts, and artificial membranes for kidneys). With PHAs bioplastics, the reliance on non-renewable resources can be reduced and the carbon footprint can also be minimized.

TRODAT-1 precursor preparation for the diagnosis of Parkinson's disease using AI retrosynthesis

Chemical retrosynthesis analysis is a technique for planning the synthesis of target molecules. The target molecules are first analyzed through recursive analysis with a search tree and are gradually disassembled into precursors with simpler structures until the obtained molecules are commercially available.

The AI (artificial intelligence) system uses a DNN (Deep neural network) model combined with Monte Carlo tree search (MCTS), referred to as 3N-MCTs for chemical retrosynthesis analysis. The chemical reactions and basic molecular database, which proposes a suggested scheme for the retrosynthesis of the target molecule, each of which has a patent or literature basis therefore guarantees the data accuracy.

Parkinson's and Alzheimer's disease are two major neurodegenerative diseases for the elderly, emphasizing the necessity for developing related diagnostic drugs. NARI used the aforementioned AI retrosynthesis to prepare the precursor TRODAT-1 with total yield increased by 4.2% compared with the original process, and purity improved more than 98%. The AI application in chemical retrosynthesis will open up a new direction for NARI in the research and development of nuclear pharmaceutics.
