The influences of annealing temperature in N2 atmosphere on interfacial chemical properties and band alignment of AlN/Si structure deposited by atomic layer deposition have been investigated based on x-ray photoelectron spectroscopy and spectroscopic ellipsometry. It is found that more oxygen incorporated into AlN film with the increasing annealing temperature, resulting from a little residual ...

(111)-oriented cubic polytypes of silicon carbide (3C-SiC) films were grown by chemical vapor deposition on 2H-AlN(0001)/Si(111) and 2H-AlN(0001)/Si(110) templates. The structural electrical properties the investigated. For film thicknesses below 300 nm, 3C-SiC material deposited 2H-AlN/Si presented a better quality than directly Si(111) using well-established two-step carbonization–epitaxy pro...

This study reports piezoelectric properties and crystallographic microstructures of aluminium nitride (AlN, wurtzite structure) thin films on 50 μm thick stainless steel foil. The transverse piezoelectric coefficient d31,f and e31,f of 10 μm thick AlN films were estimated as -1.42 ± 0.08 pm/V and -0.48 ± 0.03 C/m 2 from a tip displacement of the piezoelectric cantilevers. Dielectric constant ε3...

ABSTRACT: This work investigates the fundamental growth of c-axis oriented piezoelectric AlN thin films by RF reactive sputtering on p-type (100) and (110) silicon substrates. Substrates are treated with a 1% HF solution before deposition to remove the native oxide followed by backsputtering using argon ions. X-ray diffraction shows a (0001) oriented columnar texture of AlN grains which is the ...

Long courses of bisphosphonates are widely administered to children with osteogenesis imperfecta (OI), although bisphosphonates do not block mutant collagen secretion and may affect bone matrix composition or structure. The Brtl mouse has a glycine substitution in col1a1 and is ideal for modeling the effects of bisphosphonate in classical OI. We treated Brtl and wildtype mice with alendronate (...

BACKGROUND The node classification outlined in the seventh edition of the TNM classification is based solely on the number of metastasized lymph nodes. This study examined the prognostic value of apical lymph node (ALN) metastasis and the additional value of incorporating ALN status into a risk model based on the seventh edition. METHODS This was a cohort study of patients with stage III colo...

The strength of bone is correlated with bone mass but is also influenced significantly by other factors such as structural properties of the matrix (e.g., collagen mutations) and the mineral. Changes at all levels of this organization could contribute to fracture risk. We investigated the effects of alendronate (Aln) treatment on the density of mineralization and the ultrastructure of the miner...

OBJECTIVE To examine in a major cohort of patients whether or not musculoskeletal adverse effects (MAEs), similar to those seen in intravenous bisphosphonates (BP), might occur also in high dosage oral treatment regimens with alendronate (ALN) and risedronate (RSN). PATIENTS AND METHODS 612 consecutive patients treated in the osteoporosis outpatient clinic at Charite, Campus Benjamin Franklin...

Recent progress in osteoporosis treatment has realized prevention of osteoporotic fractures. However, there is no guideline regarding which agent should be used in an individual patient. In this report, we investigated the effectiveness of several drugs for osteoporosis in a head-to-head comparative study. A total of 776 osteoporotic patients were treated with alendronate (ALN, n=197), etidrona...

A 40-year-old man underwent emergent pulmonary artery thromboembolectomy for pulmonary artery thromboembolism, and an ALN filter was placed in the inferior vena cava immediately after the operation. He had sudden ventricular tachycardia with dyspnea on postoperative day 6. An emergent operation was successfully performed, and the ALN filter was observed at the tricuspid valve with a large amoun...
