High‐Entropy Alloy Interlayers Toward Advanced Joining for High‐Performance Structural Applications: Current Progress and Emerging Challenges

open access: yesAdvanced Engineering Materials, EarlyView.
HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

open access: yesAdvanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

open access: yesAdvanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Nuclear Imaging

Veterinary Clinics of North America: Small Animal Practice, 1993
Nuclear imaging (scintigraphy) is a noninvasive diagnostic procedure that can provide complementary information to that obtained by radiography, CT, MRI, or ultrasonography. Nuclear imaging is based on physiologic distribution of radiopharmaceutical compounds within the body so that it allows assessment of organ functions. When digital image processing

Nuclear Imaging in Urology

Urologic Clinics of North America, 1979
Over the past 10 years nuclear renal imaging has proved to be a valuable diagnostic tool. The information derived from such studies must be correlated with all other imaging procedures now available, i.e., ultrasound and computed tomography. Prior to performing a study, the physician should focus carefully on what information is desired and whether or ...

Nuclear Imaging of Osteoma

Clinical Nuclear Medicine, 2008
Abstract: Osteomas are benign osteogenic tumors that arise fromthe proliferation of cancellous or compact bone. Osteomas areusually found in craniofacial bones. Surgery is indicated only whenthe lesions exhibit cosmetic changes, become symptomatic, or growactively.

Nuclear cardiac imaging

Current Opinion in Cardiology, 1991
Important developments in the field of nuclear cardiac imaging include increasing use of single-photon emission computed tomography; the availability of pharmacologic stress testing; the introduction of newer technetium-labeled perfusion imaging agents; and a number of other newer imaging agents and imaging techniques.

Nuclear Imaging in Sarcoidosis

Seminars in Nuclear Medicine, 2018
Sarcoidosis is a multisystem granulomatosis which may result in a wide variety of clinical and biological presentations. Symptoms are often nonspecific, and incidental abnormal findings on chest radiography is rather common. Although sarcoidosis resolves favorably in most cases, some localizations can provoke functional impairment or even impact on ...

NUCLEAR HEPATOBILIARY IMAGING

Radiologic Clinics of North America, 1993
Recent improvements in hepatobiliary radiopharmaceuticals and the high prevalence of biliary tract disease have resulted in a larger role for hepatobiliary imaging in clinical applications. The use of hepatobiliary imaging in assessing hepatic blood flow, hepatocyte function, biliary drainage, and complications in patients with jaundice or abdominal ...
