Photoelectron spectroscopy is used to investigate aluminum dideuteride cluster anions, AlnD2- (n=3,6-15), produced by laser vaporization of a pure Al target with a D2-seeded helium carrier gas. Comparison between the well-resolved photoelectron spectra of AlnD2- and Aln- reveals the nature of interactions between D2 and Aln-. Depending on the size of the Aln- clusters and their electronic struc...

To determine if protein expression in primary breast cancers can predict axillary lymph node (ALN) metastasis, we assessed differences in protein expression between primary breast cancers with and without ALN metastasis using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS). Laser capture microdissection was performed on invasive breast cancer frozen ...

BACKGROUND Axillary lymph nodes (ALN) are the most commonly involved site of disease in breast cancer that has spread outside the primary lesion. Although sentinel node biopsy is a reliable way to manage ALN, there are still no good methods of predicting ALN status before surgery. Since morbidity in breast cancer surgery is predominantly related to ALN dissection, predictive models for lymph no...

objective(s): studies have reported that whole body vibration (wbv) played a vital role in bone remodeling. circulating serotonin is also involved in negative regulating bone mass in rodents and humans. however, both wbv and inhibition of serotonin biosynthesis may suppress receptor activator of nuclear factor-kappab ligand (rankl)-induced osteoclastogenesis in vitro . the purpose of the curren...

PURPOSE This study assessed the axillary lymph node (ALN)-to-primary tumor maximum standard uptake value (SUVmax) ratio (ALN/T SUV ratio) in invasive ductal breast cancer (IDC) on preoperative (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) to determine the effectiveness in predicting recurrence-free survival (RFS). METHODS One hundred nineteen IDC patie...

This study was designed to experimentally measure the thermal and electrical conductivities of Aluminium Nitride/Ethylene Glycol (AlN/EG) nanofluids. Transmission electron microscopy (TEM) was used to characterize the shape of AlN nanoparticles. Nanofluids with different particle volume concentrations of 0.5%, 1%, 2%, 3%, 4%, and 5% were utilized. The thermal and electrical conductivities of the...

Aluminum nitride (AlN) thin films have potential applications in microelectronic and optoelectronic devices. In this study, AlN thin films with different thicknesses were deposited on silicon substrate by single ion beam sputtering method. The X-ray diffraction (XRD) spectra revealed that the structure of films with thickness of - nm was amorphous, while the polycrystalline hexagonal AlN with a...

An effective passivation technique for AlGaN/GaN HEMTs is presented. This technique features ultrathin AlN film grown by atomic layer deposition (ALD). With in-situ remote plasma pretreatment prior to the AlN deposition, atomic sharp interface between ALD-AlN and III-nitride can be obtained. Significant current collapse suppression and dynamic ON-resistance reduction are demonstrated in the ALD...
