Published: June 2020

In the present work, a method for adjusting a crystal analyzer to separate two characteristic lines from the spectrum of a conventional X-ray tube for simultaneous registration of tomographic projections is proposed. The experimental implementation of this method using radiation of a molybdenum anode (α, β lines) and a silicon Si(111) crystal analyzer in Laue geometry is presented. Projection images at different wavelengths are separated in space and can be recorded independently for further processing. Potential uses of this scheme are briefly discussed.

Quantifying crystallinity of amlodipine maleate in amorphous solid dispersions produced by fluidized bed granulation using PAT tools.

Eur J Pharm Sci

One of the main concerns with formulations containing amorphous solid dispersions (ASDs) is their physical stability. Stability can be compromised if a formulation contains any residual crystallinity of an active pharmaceutical ingredient (API) that could act as seeds for further crystallisation. This study presents four methods for crystalline amlodipine maleate quantification in ASD, which were developed using one Raman and three NIR process analysers.

Simulations of the potential for diffraction enhanced imaging at 8 kev using polycapillary optics.

Conventional x-ray radiography relies on attenuation differences in the object, which often results in poor contrast in soft tissues. X-ray phase imaging has the potential to produce higher contrast but can be difficult to utilize. Instead of grating-based techniques, analyzer-based imaging, also known as diffraction enhanced imaging (DEI), uses a monochromator crystal with an analyzer crystal after the object.

Background: Urinalysis is a commonly performed test for the diagnosis and prognosis of kidney disease in hospitalized patients. It involves examining the chemical composition of the urine and microscopy to examine the cells and casts. In clinical settings, urinalysis is frequently delayed by several hours after sample collection and held at room temperature.

Hematite (α-FeO) nanoparticles have been synthesized from waste source of iron which contains a prominent amount of iron (93.2 %) and investigated the effect of low temperature calcination. The two-step synthesis method involved preparing ferrous sulfate through acid leaching process followed by oxidation and calcination at temperatures ranging from 200 to 400 °C to produce the desired α-FeO in nano form.

Background: To explore the underlying causes of significant fluctuations in creatinine levels within three days due to transient and severe uric acid elevation, and to provide evidence for the interpretation of abnormal test results and clinical diagnosis and management.

Methods: The issues were resolved by retesting the samples, comparing results across different detection platforms, and analyzing the reaction curve. We comprehensively reviewed patients' general conditions, imaging examinations, and treatments.
