Forskning på Institut for Naturvidenskab og Miljø

Vi underviser og forsker anvendelsesorienteret og innovativt i virkelighedens naturvidenskab og miljø. Vi arbejder samtidig med  grundvidenskab, der forklarer og udvikler de teorier, naturvidenskaben bygger på.

Grundforskning og anvendt forskning går hånd i hånd på INM. Vi har gode eksempler på, at vores forskning fører til både ny viden, nyttig innovation, udvikling af patenter og indtjeningspotentiale til erhvervslivet.

Institut for Naturvidenskab & Miljø forsker bl.a. inden for:

  • Bløde og amorfe materialers fysik
  • Grøn - bæredygtig kemi
  • Matematik- og naturfagsdidaktik
  • Matematisk modellering
  • Miljødynamik og økologi
  • Sundhed og sygdom

    Other instruments

    The section is also equipped with a number of other instruments, such as infrared and UV spectrometers, preparative and analytical chromatographic equipment (HPLC, radial LC, size exclusion), rheometers (Bohlin VOR and Haake RS100), calorimeters (ITC and DSC), photochemical lamps (400 and 125 W medium pressure Hg) and reaction vessels, and chemical computation facilities (Gaussian and Macromodel).

    Miljøbiologi

    The Environmental Dynamics Section is equipped with modern analytical facilities, as well as with facilities for growing plants and algae and assessing their physiological status. The latter include:

    • Photobioreactors (PBRs) for the production of microalgae
      The PBRs include two bubble-column PBRs, each of 50 L, and two tubular PBRs, each of 250 L.
    • Equipment for PAM fluorometry
      This equipment include a basic Hansatech FMS-1, as well as a Walz Image-Pam and a Walz Microscopy-PAM.
    • IRGAs
      We have two infrared gas analyzers, a CIRAS-3 single channel system for absolute measurement and a CIRAS-3 dual channel system for differential measurements.
    • Field spectroradiometer
      For field as well as laboratory measurements of plant and vegetation light reflection, we have an ASD FieldSpec spectroradiometer.
