The Li4Ti5O12 (LTO) compound has been investigated as an alternative negative electrode material for lithium ion batteries (LIBs), which are being used as energy storage devices in stationary systems as well as for electric vehicles due to their many interesting features. LTO compound has shown a remarkable Li-ion intercalation/de-intercalation reversibility, demonstrating also zero-strain volume change

The changes in aerosol physical properties were studied by applying Nanoparticle-Enhanced Laser Ablation Inductively Coupled Plasma Mass Spectrometry (NE-LA-ICP-MS). This approach was compared to conventional LA-ICP-MS method. Analyte signal enhancement was related to particle number concentration of aerosol for three sizes of Au nanoparticles (NPs) applied on the metal sample surface in form of droplets

The calorific value of coal mainly depends on the content of combustible organic elements and ash, which is a comprehensive indicator of coal quality. It is of great significance to quickly obtain the calorific value of coal into the boiler for the optimal control of coal blending and combustion in thermal power generation. However, the measurement repeatability of LIBS for coal calorific value has

Increased demand for improving ultra-low background detection capabilities for rare-event fundamental physics applications has resulted in the need for fast, convenient and clean assay methodologies that either preclude or reduce chemical sample pre-processing. A novel technique for the measurement of ultra-trace concentrations (fg·g-1 level) of natural 232Th and 238U and non-natural tracer isotopes

The technological advances in lasers enabled the wide applications of laser-induced breakdown spectroscopy (LIBS) as a powerful analytical mean for elemental analyses. Rather than commonly used lasers that operates at several to several-tens of Hz, the high repetition rate ones that operates at tens of kHz suggested superior analytical advantages while implying unique excitation pathways. Specifically

Throughout the recent years, laser-induced breakdown spectroscopy (LIBS) has gained significant attention as a mean for simple elemental analyses. The suitability of LIBS for contactless analysis allows it to be a perfect candidate for underwater applications. While the majority of LIBS systems are still relying upon sub-kHz pulsed lasers, this contribution introduces 10s-kHz low pulse-energy lasers

Total reflection X-ray fluorescence (TXRF) spectrometry is a very effective multi-elemental analytical technique for the measurements of metal ions at ultra trace concentration in aqueous samples. In this work a novel and simple TXRF based method has been developed for the quantification and speciation of arsenic (As) at ultra trace levels in water samples. The quartz supports used for TXRF measurements

Copper matrix-matched calibration samples were prepared by doping the high purity copper powders (99.999%, 500-600μm) with multi-element standard solutions with total 72 elements, and then relative sensitivity factors (RSFs) of 72 elements in both microsecond-pulsed and direct current (dc) mode were determined by using Element GD type glow discharge mass spectrometry (GD-MS). The ability of pulsed-GD-MS

Pulsed laser deposition (PLD) can be used as a sampling tool for chemical characterization of irradiated nuclear fuel, when coupled with mass spectrometry analysis. The quantity of sample obtained by PLD is too small (typically a few nanograms), thereby reducing the radiation exposure to a considerable extent and still provides spatial profile of irradiated pellet accurately (uncertainty error ~ 1

A novel sensitive vapor generation sampling method of nebulized film dielectric barrier discharge (NFDBD) coupled with inductively coupled plasma mass spectrometry (ICP-MS) was developed for noble metals (Rh, Pd, Ir, Pt, and Au) determination simultaneously in this work. In the presence of formic acid, a 5-11 fold sampling efficiency of Rh, Pd, Ir, Pt, and Au by NFDBD was improved compared with the

Single particle ICP-mass spectrometry (spICP-MS) has been used to define size and number concentration of nanoparticles (NPs). In this study, we have developed a new analytical approach to extend the analytical size range of NPs toward a larger region. To achieve this, signal intensities of Au related polyatomic ions such as 197Au12C+, 197Au14N+, 197Au16O+, and 197Au40Ar+, instead of 197Au+, were used
