Poly(ethylene oxide) (PEO) oligomers are employed extensively in pharmaceutical and biomedical arenas mainly due to their excellent physical and biological properties, including solubility in water… (More)
This work was performed as a continuation of ablative laser propulsion (ALP) research recently revived by the authors. An ALP-based space vehicle would be driven by high-energy, short-duration (10… (More)
This paper represents a review of studies devoted to Ablative Laser Propulsion and conducted by the Laser Propulsion Group (LPG) at the University of Alabama in Huntsville.
Specie c impulse, thrust, and other dynamic characteristics of solid elemental propellants for ablative laser propulsion are studied experimentally with the aid of a piezoelectric force sensor. This… (More)
This work summarizes the combination of experimental and digital image processing technique developed for determination of plasma expansion velocity angular profiles. Such profiles were used further… (More)
The compression properties of an aluminium foam containing a nonuniform density gradient have been examined. Specimens were taken from various locations within the foam slab, and were tested in two… (More)
Phase explosions (PEs) have been observed at tens of microseconds delay after laser pulse arrival on carbon, aluminium, silicon, iron, copper, zinc, tin and lead targets ablated at an irradiance… (More)
We report a novel, noncovalent hydrogel system crosslinked solely by receptor-ligand interactions between biotin and avidin. The simple hydrogel synthesis and functionalization together with the… (More)
The syntheses, crystal structures and magnetochemical characterization are reported for two new Fe complexes [Fe18O6(OH)8(pdm)10(pdmH)4(H2O)4](ClO4)10 (3) and [Fe9O4(OH)2(O2CMe)10(pdm)(pdmH)4](NO3)… (More)
This paper presents an updated review of studies on Ablative Laser Propulsion conducted by the Laser Propulsion Group (LPG) at the University of Alabama in Huntsville. In particular, we describe the… (More)
