The growth in situ of isolated mandibular segments
American Journal of Orthodontics, 1978M uch of the present controversy surrounding the study of mandibular growth concerns the role of condylar cartilage. It was once widely assumed that condylar growth is directly responsible for mandibular translation.“. 35-37 The condylar hypothesis was based to a considerable extent on the facile assumption that condylar cartilage serves as an ...

In situ approaches to establish colloidal growth kinetics
Journal of Colloid and Interface Science, 2004A technique based on the back scattering phenomenon of dynamic light scattering has been employed to monitor the kinetics of gold and platinum metal nanoparticle growth and silver nanoparticle oxidation as well as in the determination of particle sizes ranging from 1 to 200 nm in diameter. The systems were chosen to examine the applicability of dynamic

In situ continuous growth formation of synthetic biominerals
Chemical Communications, 2013Continuous self-assembled growth of both the organic and inorganic components of materials with nacre-like structure is achieved upon mineralisation of chitin and chitosan scaffolds using a combined soaking method and the inclusion of poly(acrylic acid) and chitosan oligomers as additives.

In Situ Quantum Dot Growth on Multiwalled Carbon Nanotubes
Journal of the American Chemical Society, 2003The generation of nanoscale interconnects and supramolecular, hierarchical assemblies enables the development of a number of novel nanoscale applications. A rational approach toward engineering a robust system is through chemical recognition. Here, we show the in situ mineralization of crystalline CdTe quantum dots on the surfaces of oxidized ...

In Situ Observation of Oscillatory Growth of Bismuth Nanoparticles
Nano Letters, 2012We study the growth of Bi nanoparticles in an engineered precursor-scarce environment in a liquid cell at an elevated temperature (180 °C) using transmission electron microscopy. Observation reveals dynamics of oscillatory growth of individual nanoparticles, pairwise Ostwald ripening and anti-Ostwald ripening and a global collective oscillation.

In situ growth and characterization of ultrahard thin films
Microscopy Research and Technique, 1998Results concerning the operation of a new ultrahigh vacuum (UHV) ion-beam assisted deposition system for in situ investigation of ultrahard thin films are reported. A molecular beam epitaxy (MBE) chamber attached to a surface science system (SPEAR) has been redesigned for deposition of cubic-boron nitride thin films.

In situ reflectance monitoring of epitaxial growth
2000 Digest of the LEOS Summer Topical Meetings. Electronic-Enhanced Optics. Optical Sensing in Semiconductor Manufacturing. Electro-Optics in Space. Broadband Optical Networks (Cat. No.00TH8497), 2002Epitaxial growth of compound semiconductors is accomplished with MOCVD or MBE. In both these methods, many process variables must be precisely controlled to achieve the proper combination of layer thickness, chemical composition, lattice matching, and doping levels required by modern compound semiconductor devices.

In Situ Study of Noncatalytic Metal Oxide Nanowire Growth
Nano Letters, 2014The majority of the nanowire synthesis methods utilize catalyst particles to guide the nanowire geometry. In contrast, catalyst-free methods are attractive for facile fabrication of pure nanowires without the need for catalyst preparation. Nonetheless, how nanowire growth is guided without a catalyst is still widely disputed and unclear.
