Atomic spectrometry update. Advances in atomic emission, absorption, and fluorescence spectrometry, and related techniques

, 2004
This is a new review covering developments in 'atomic spectrometry'. It combines the content of the previously separate ASU reviews on 'atomic emission, absorption and fluorescence spectrometry'1 and 'atomic mass spectrometry',2 but excluding material on

Microstructure‑Dependent Phase Transformations Under High‑Pressure Laser Heating in Additively Manufactured AlCrFe2Ni2

Advanced Engineering Materials, EarlyView.
Additively manufactured AlCrFe2Ni2 with contrasting BCC/B2‐dominant and lamellar FCC + BCC/B2 microstructures exhibits the same pressure‐induced BCC/B2 → HCP transformation. Under laser heating at high pressure, HCP is destabilized, and a cubic BCC/B2 + FCC assemblage is recovered, while the lower‐scan‐speed microstructure transforms at a lower ...

Use of energy dispersive X-ray fluorescence (EDXRF) spectrometry to determine external markers in animal intake estimation trials

The study evaluated the accuracy of EDXRF spectrometry for measuring titanium (Ti) and chromium (Cr) in fecal and dietary samples as markers for fecal output and forage intake in grazing animals. Standard addition calibrations were performed using Tifton

Characterization of ceramic seeds with samarium-153 for use in brachytherapy

Materials Research, 2011
Ceramic seeds were synthesized by the sol-gel technique with Si:Sm:Ca. One sample was irradiated in the TRIGA nuclear reactor IPR-R1. After irradiation, the seeds were submitted to instrumental neutron activation analysis to determine the 153Sm ...

Microstructural, Mechanical, and Textural Evolution of Dissimilar Combination of Laser‐Welded Maraging Steel and 4340 Steel

Advanced Engineering Materials, EarlyView.
The present work reports the microstructural, mechanical, and texture evolution of a dissimilar combination laser‐welded maraging steel with 4340 steel. This is important for aerospace applications. The demand for dissimilar welding is growing rapidly with the requirement of efficient and durable joints.

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Green Synthesis of 8‐Hydroxyquinoline Barium as Visible‐Light‐Excited Luminescent Material Using Mechanochemical Activation Method

Global Challenges, 2019
Using high‐energy UV‐light to excite 8‐hydroxyquinoline barium (BaQ2) is a short slab for this emerging area of organic luminescent materials. However, using visible light to excite BaQ2 has not been reported.

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed
