Abstract Bone is a hierarchically structured composite material which, in addition to its obvious biological value, has been well studied by the materials engineering community because of its unique structure and mechanical properties. This article will review the existing bone literature, with emphasis on the prevailing theories regarding bone formation and structure, which lay the groundwork for...

The purpose of this research review is to open dialog about quantitative, qualitative, and mixed research methods in engineering education research. Our position is that no particular method is privileged over any other. Rather, the choice must be driven by the research questions. For each approach we offer a definition, aims, appropriate research questions, evaluation criteria, and examples from ...

Biologically mineralized tissues are well recognized for their unusual crystal morphologies and hierarchically organized composite structures. The soluble acidic macromolecules associated with biominerals are thought to play an important role in modulating the mineral morphology. Our in vitro studies, which use acidic polypeptide additives to modify crystal growth of calcium-based minerals, have d...

Abstract Collagen self-assembly in vitro was conducted in the pH range from 6.0 to 10.5 at 30 °C in order to investigate the electrostatic interactions that occur during fibril formation. A sigmoidal curve was observed in the growth rate of fibrils. Collagen fibril morphologies imaged by transmission electron microscopy (TEM) and scanning electron microscopy (SEM) present bundling of fibrils with ...

We have put forth the hypothesis that collagen is mineralized during bone formation by means of a polymer-induced liquid-precursor (PILP) process, in which a liquid-phase mineral precursor could be drawn into the gaps and grooves of the collagen fibrils by capillary action, and upon solidification, leave the collagenous matrix embedded with nanoscopic crystallites of hydroxyapatite. This hypothesi...

Optical limiting of nanosecond laser pulses at 532 nm has been observed in CdxAg1−xS semiconductor nanoparticles within organic solution of polymeric ionic aggregates. Both free-carrier absorption (FCA) and nonlinear scattering contribute to the optical limiting performance. The optical limiting response of CdS nanoparticles, in the diameter range of 2–9 nm, increases with the increase of particle...

With recent calls for expanding the scope and rigor of engineering education research, use of qualitative methods to answer research questions that can not be answered through quantitative methods is taking on increasing significance. Well-designed qualitative studies often build on epistemological consistency across theoretical perspectives, research questions, and research methods. We examine re...

In this paper, two novel methods of preparing CdS nanoparticles within the corona of block copolymer micelles are presented. (1) Corona-embedded CdS nanoparticles were prepared by dropping core-embedded CdS nanoparticles into water with a low pH value. The location change of the CdS nanoparticles was accompanied by a structural change of the micelles, from compound micelles to single micelles. The...

The biomimetic synthesis of patterned mineral thin films, based on a combination of the microcontact printing technique and a novel crystallization process called the polymer-induced liquid-precursor (PILP) process, is demonstrated. The PILP process enables the deposition of smooth and continuous calcitic mineral films (up to 1500 nm in thickness) under low-temperature and aqueous-based processing...

The effect of magnetic fields on the orientation and properties of 4,4‘-bis(2,3-epoxypropoxy)-α-methylstilbene cured with sulfanilamide has been studied. This epoxy system is initially isotropic and forms a smectic A phase upon curing. A magnetic field was applied during the cure reaction, resulting in alignment of the molecules along the direction of the applied field. Measurement of the orientat...
