Advanced Nanomaterials and Nanomanufacturing Laboratory

R. Vernon McBroom Professor: Dr. Yuris Dzenis

This unique, $2.1 million multidisciplinary experimental facility on nanomanufacturing, nanomaterials, and nano/micromechanics has been developed by Dr. Yuris Dzenis from 1995-present with funding from NSF, AFOSR, and ARO (Dzenis has served as PI/PD on five equipment grants including NSF ARI, REG, IMR, and DURIP projects). In addition to the equipment below, extensive facilities of UNL's interdepartmental Center for Materials Research and Analysis (SEM, X-ray, metallographic facilities, and others) are available for use at a nominal charge.
  • Multiple electrospinning stations
  • Fume hood and equipment for chemical processing
  • Nanoparticle and nanofiber preparation and functionalization facility
  • Custom-designed multistage high-temperature environmental oven for continuous nanomanufacturing
  • Aerospace-grade composite preparation equipment
  • Ultrahigh-speed video imaging system for observation and analysis of electrospinning jet instabilities and dynamic fracture processes
  • Multiple mini- and micro-stages for miniature specimen testing, including computerized ultrasensitive stages for in-situ mechanical testing inside SEM and FE-SEM chambers or under continuous AFM or SAM observations
  • Comprehensive thermal and thermomechanical materials characterization facility, including TGA, DSC, and multiple DMTAs
  • Two servohydraulic machines for mechanical testing of advanced materials and composites with digital test control and data acquisition systems and thermal chamber
  • Fixtures for tensile, compressive, bending, and fracture mechanics testing; multiple uniaxial and biaxial extensometers, including water-cooled high temperature extensometer
  • Equipment for low- and high-cycle fatigue testing, including isothermal and thermomechanical fatigue evaluation
  • Unique multiscale NDE facility comprising state-of-the-art ultrasonic immersion scanner, leading edge scanning acoustic tomograph, "true" scanning acoustic microscope (SAM) with 1.3 GHz imaging capability, and a universal scanning probe microscope with specimen modulation capability
  • Atomic force microscope (AFM) with environmental and thermal cells and mechanical testing stage for in-situ observations
  • Advanced acoustic emission system with digital transient recorder and extensive signal analysis software
  • Stages and fixtures for interfacial testing of composites
The group also has extensive computing facilities for simulating nanomanufacturing processes and material behavior.
