Awards: PURPOSE: THE PURPOSE OF THIS COOPERATIVE AGREEMENT TO PROVIDE UNDERGRADUATE/GRADUATE RESEARCHERS, INDIVIDUALS WITH BACHELORS OR MASTER'S DEGREES, POST-DOCTORAL ASSOCIATES, SENIOR RESEARCH FELLOWS AND ACADEMIC AFFILIATES WITH FELLOWSHIP OPPORTUNITIES AND FINANCIAL ASSISTANCE TO OBTAIN LABORATORY EXPERIENCES AND AID IN DEVELOPING COLLABORATIVE RESEARCH RELATIONSHIPS WITH NIST STAFF WITHIN THE NIST BOULDER LABORATORY.ACTIVITIES TO BE PERFORMED: PREP SEEKS TO ENCOURAGE THE GROWTH AND PROGRESS OF SCIENCE AND ENGINEERING IN THE UNITED STATES, INCLUDING THE ENCOURAGEMENT OF WOMEN AND MINORITY RESEARCHERS SEEKING TO FURTHER THEIR PROFESSIONAL DEVELOPMENT, AND TO NURTURE RESEARCHERS AND POST-DOCTORAL ASSOCIATES CONSIDERED TO BE POTENTIAL FUTURE NIST EMPLOYEES.EXPECTED OUTCOMES: THE OBJECTIVES OF THE PREP PROGRAM ARE TO: 1) ENCOURAGE THE GROWTH AND PROGRESS OF SCIENCE AND ENGINEERING IN THE UNITED STATES BY PROVIDING RESEARCH OPPORTUNITIES FOR PREP RESEARCHERS WITH NIST SCIENTISTS AND ENGINEERS AND EXPOSING THEM TO CUTTING-EDGE RESEARCH AND DEVELOPMENT (R&D); 2) PROMOTE THE PURSUIT OF DEGREES OR PROFESSIONAL DEVELOPMENT, AS APPLICABLE, FOR PREP RESEARCHERS; AND 3) PROMOTE DIVERSITY AND EQUITY IN STEM.INTENDED BENEFICIARIES: NIST AND NIST RESEARCHERS, AND UNDERGRADUATE/GRADUATE RESEARCHERS, INDIVIDUALS WITH BACHELORS OR MASTER'S DEGREES, POST-DOCTORAL ASSOCIATES, SENIOR RESEARCH FELLOWS AND ACADEMIC AFFILIATES, EMPLOYED BY OR AFFILIATED WITH THE UNIVERSITIES.SUBRECIPIENT ACTIVITIES: THE RECIPIENT DOES NOT INTEND TO SUBAWARD FUNDS., G2467384604, PURPOSE: THE PURPOSE OF THIS GRANT IS TO ADVANCE UNDERSTANDING OF THE STRUCTURE-PROPERTY-PROCESS RELATIONSHIPS IN NOVEL IMPACT MITIGATING MATERIALS. THESE MATERIALS ARE IMPORTANT FOR SUCH FIELDS AS SPORTS, MILITARY, AND LAW ENFORCEMENT PROTECTION.ACTIVITIES TO BE PERFORMED: THROUGH THIS RESEARCH, FOUR SPECIFIC ACTIVITIES WILL BE CONDUCTED. THESE ARE ADVANCING METROLOGY FOR IN-SITU MECHANICAL SPECTROSCOPY TO CHARACTERIZE SHEAR THICKENING FLUIDS (STF) FOR USE IN PROTECTIVE APPLICATIONS, UTILIZE HIGH SPEED ULTRASOUND IMAGING OF IMPACT EXPERIMENTS TO UNDERSTAND THE FORMATION OF SHEAR JAMMING FRONTS, PERFORM DROP-TOWER (CLOSE TO REAL WORLD) EXPERIMENTS FOR NOVEL COMPOSITE MATERIAL DESIGNS, AND EXAMINE RESIDUAL STRESS IN THESE COMPOSITE MATERIALS TO BETTER UNDERSTAND ITS EFFECT ON IMPACT MITIGATION. EXPECTED OUTCOMES: THE OVERARCHING EXPECTED OUTCOME OF THIS WORK IS A CLEARER UNDERSTANDING OF HOW THE INCORPORATION OF NOVEL MATERIALS SUCH AS SHEAR THICKENING FLUIDS INTO IMPACT MITIGATING MATERIALS CAN AFFECT THEIR PERFORMANCE, AND THE ESTABLISHMENT OF NEW METROLOGIES TO ASSESS THESE MATERIALS. THIS INFORMATION WILL BE SHARED WITH THE BROADER COMMUNITY THROUGH RESEARCH PRESENTATIONS, PUBLICATIONS, AND RELEASE OF RELEVANT DATA. THE INFORMATION GLEANED FROM THIS WORK MAY HAVE IMPLICATIONS FOR THE DESIGN OF MATERIALS FOR USE IN ARMOR, AEROSPACE, AUTOMOTIVE, AND PROTECTIVE APPLICATIONS. INTENDED BENEFICIARIES: USERS OF PROTECTIVE EQUIPMENT MAY BENEFIT FROM THIS WORK, AS MORE EFFICIENT MATERIAL DESIGN CAN RESULT FROM THE INFORMATION AND DATA DEVELOPED THROUGH THIS PROPOSAL. THIS COULD RESULT IN LIGHTER, SAFER ARMOR MATERIALS FOR USE BY LAW ENFORCEMENT AND MILITARY USERS, AND MORE EFFECTIVE SPORTS PROTECTIVE GEAR FOR USE BY THE GENERAL PUBLIC. SUBRECIPIENT ACTIVITIES: THE RECIPIENT DOES NOT INTEND TO SUBAWARD FUNDS.
