Neutron Activation Analysis: A Primary (Ratio) Method to Determine SI-Traceable Values of Element Content in Complex Samples

CHIMIA, 2009
The metrological principles of neutron activation analysis are discussed. It has been demonstrated that this method can provide elemental amount of substance with values fully traceable to the SI. The method has been used by several laboratories

Interlaboratory Comparison of Radioimmunological Calcitonin Determination [PDF]

cclm, 1982
An interlaboratory study for the radioimmunological determination of calcitonin was performed within the European PTH Study Group (ESPG), to improve comparability using external quality control. Twelve laboratories determined calcitonin in 21 deep frozen samples using their respective calcitonin radioimmunoassay systems. The samples included a standard

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Interlaboratory comparison of magnetic thin film measurements

Journal of Research of the National Institute of Standards and Technology, 2003
A potential low magnetic moment standard reference material (SRM) was studied in an interlaboratory comparison. The mean and the standard deviation of the saturation moment m s, the remanent moment m r, and the intrinsic coercivity H c of nine samples were extracted from hysteresis-loop measurements. Samples were measured by thirteen laboratories using

Harnessing the nonthermal effects of ultrasound for cancer treatment: From mechanisms to applications

Smart Molecules, EarlyView.
Nonthermal ultrasound transforms acoustic energy into diverse therapeutic bioeffects through cavitation, mechanical stimulation, and physicochemical activation. This review discusses how acoustic parameters, biological mechanisms, and responsive materials interact to influence nonthermal ultrasound‐enabled cancer therapies. Mechanism‐guided engineering

Evaluation of cold joint effects on the microstructure and mechanical behavior of three‐dimensional printed concrete specimen

Structural Concrete, EarlyView.
Abstract 3D concrete printing (3DCP) is an automated construction technique that uses an extrusion process to fabricate structures efficiently. However, the layer‐by‐layer process can create interlayer weaknesses, and interruptions during printing can result in cold joints, which can negatively affect the structural behavior.

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

Environmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.
