Alpha spectrometry applications with mass separated samples [PDF]

Applied Radiation and Isotopes, 2016
(241)Am has been deposited using a novel technique that employs a commercial inductively coupled plasma mass spectrometer. This work presents results of high-resolution alpha spectrometry on the (241)Am samples using a small area passivated implanted planar silicon detector. We have also investigated the mass-based separation capability by developing a

Identification of bile alcohols in urine from healthy humans.

Journal of Lipid Research, 1984
Bile alcohols present in urine from healthy adults were studied. Urine was extracted with octadecylsilane-bonded silica gel, and a neutral fraction and a glucuronide fraction were isolated by ion exchange chromatography on piperidinohydroxypropyl ...

Design by numerical simulation of an in situ alpha spectrometer operating at ambient air pressure [PDF]

EPJ Web of Conferences, 2020
Alpha emitters are usually identified and quantified by alpha spectrometry measurements in a vacuum chamber performed in laboratory environments. This study shows that transuranic elements can be distinguished under ambient conditions using a grid ...

Sequential separation of uranium and plutonium in urine sample using UTEVA resin

Radiation Protection and Environment
This article describes the process of separating uranium (U) and plutonium (Pu) sequentially in urine samples through the use of UTEVA resin. The manuscript optimizes several parameters, including the concentration of nitric acid in the loading solution,

Structure of the side chain of the C29 dicarboxylic bile acid occurring in infants with coprostanic acidemia.

Journal of Lipid Research, 1982
The structure of the side chain of the 3 alpha, 7 alpha, 12 alpha-trihydroxy-5 beta-C29 dicarboxylic bile acid occurring in body fluids of infants with coprostanic acidemia was investigated by means of mass spectrometry and nuclear magnetic resonance ...

Alpha-1-antitrypsin: a novel human high temperature requirement protease A1 (HTRA1) substrate in human placental tissue. [PDF]

PLoS ONE, 2014
The human serine protease high temperature requirement A1 (HTRA1) is highly expressed in the placental tissue, especially in the last trimester of gestation. This suggests that HTRA1 is involved in placental formation and function.

The Effects of High-Energy Carbon Co-Doping on IMB-CNM LGAD Fabrication and Performance

Sensors
Over the past few years, Low-Gain Avalanche Detectors (LGADs) have demonstrated excellent timing performance, showing great potential for use in 4D tracking of high-energy charged particles. Carbon co-doping is a key factor for enhancing LGAD performance,

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
