In this webinar, PANalytical will introduce to you the main features of this instrument and demonstrate its unique capabilities by discussing several application examples.

The Empyrean Nano edition enables a variety of X-ray scattering techniques that can be applied for the structural characterization of nanomaterials on multiple length scales. The instrument is based on a high-resolution goniometer platform and the proven PreFIX concept, thus offering maximum flexibility. Main applications are SAXS/WAXS, bio-SAXS, USAXS and total scattering (PDF analysis).

Webinar – Solving the challenges of Na-ion battery electrodes using PXRD

The Webinar will be displayed on the main monitor in the lobby of the characterization suite in the Marcus Nanotechnology Center at 10:00AM on July 28th.

Sodium layered oxides, NaxMO2 (M = Ti – Cu), show great promises as positive electrode material candidates for Na-ion batteries. However, detailed structural analysis of these materials presents many difficulties owing to their reactivity in ambient conditions, numerous structural transitions as a function of the sodium content and extended stacking fault occasionally resulting in partial amorphization of the sample.

This webinar will cover the study of P2-NaxFe1/2Mn1/2O2 positive electrode material focusing on the powder X-ray diffraction (PXRD) data collection strategies used to address the challenges inherent to sodium layered oxide in general.

XRF Webinar to play in Marcus Lobby – July 14th

We will be presenting a Webinar about XRF (X-ray fluorescence) from Bruker on the large monitor in Marcus on July 14th at 10:00AM.

XRF  is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source.

The webinar will describe how the M4 TORNADO can be used to identify high and low angle grain boundaries as well as twin boundaries in crystalline materials. From polycrystalline silicon wafers to aluminum samples and welding joint, the method presented in this webinar allows the user to obtain information on the crystals such as size and distribution.

Denver X-Ray Conference

Hello everyone!

The 2016 Denver X-ray Conference is heading to Chicago and they are looking for students! The 65th Annual Conference on Applications of X-ray Analysis will be held at the Westin O’Hare Hotel in Rosemont, Illinois from August 1st – August 5th.  They offer many student incentives, including a low student registration fee, reduced cost student housing, Robert L. Snyder Student Travel Grants, the Jerome B. Cohen Student Award, a student pizza lunch with the DXC Organizing Committee, and Best Student Poster awards.

The deadline is June 1st for all Robert L. Snyder Student Travel Grant applications, and for the Jerome B. Cohen Student Award. Visit the ICDD website to read more about the awards, the application requirements, and other opportunities available to students who attend DXC.
