The pore geometries also affect their permeability. Imaging the visible pore space provides insights into the physical pore space, pore geometries, and the associated mineral and organic matter phases relevant for storage and transport. For example, organic-matter porosity is an important property of mature organic-rich shales providing storage capacity for liquids and gases, like hydrocarbons. Imaging the microstructure is the only technique which delivers data giving direct insight into the organic matter porosity. However, imaging porosity in fine-grained shale as well as carbonate rocks in a representative way at high resolution is challenging. https://www.leica-microsystems.com//science-lab/macroscale-to-nanoscale-pore-analysis-of-shale-and-carbonate-rocks/ Tue, 04 Sep 2018 22:00:00 +0000 PhD Jop Klaver, PhD Joyce Schmatz, MSc Mingze Jiang, PhD James DeRose https://www.leica-microsystems.com/19763 Metallography Quality Assurance Forensics See the Structure with Microscopy - Know the Composition with Laser Spectroscopy The advantages of a 2-in-1 materials analysis solution combining optical microscopy and laser induced breakdown spectroscopy (LIBS) for simultaneous visual and chemical inspection are described in this report. The basic principles of the 2-in-1 solution and a comparison between it and other common materials analysis methods, such scanning electron microscopy (SEM), are explained to demonstrate how a rapid, efficient workflow is achieved. A 2-in-1 analysis solution can reduce significantly the cost and time for obtaining material image and composition data. Such data are instrumental in assuring quality and reliability to make confident decisions quickly during production, quality control, failure analysis, and research and development in industries and fields, such as automotive and metallurgy. https://www.leica-microsystems.com//science-lab/see-the-structure-with-microscopy-know-the-composition-with-laser-spectroscopy/ Mon, 11 Jun 2018 13:39:00 +0000 PhD James DeRose, Dr. Kay Scheffler https://www.leica-microsystems.com/20117 Metallography Leica is MAD about LIBS When analyzing material for cleanliness testing, users normally just want a simple way to know whether the particle under scrutiny is normal debris or something more risky. Users can now “LIBS” it to acquire rapidly the composition and then move onto the next manufacturing step. https://www.leica-microsystems.com//science-lab/leica-is-mad-about-libs/ Sun, 22 Apr 2018 22:00:00 +0000 Mike Tjepkema, PhD James DeRose https://www.leica-microsystems.com/19722 Digital Microscopy Free Webinar On-Demand: Digital Microscopy in Earth Science Classical polarized light (compound) microscopes can only be used for prepared samples, because the working distance they offer is insufficient for whole samples. This means that thicker and bigger geological samples have to be sectioned and polished to fit under the limited working distance of a compound microscope. The Leica DVM 6 provides outstanding image quality, extra working distance and allows geologists to work with polished and unpolished samples (micro mounts, fossils, drilled cores …), make 3D reconstructions of their surfaces and enables classical petrographic work as well. https://www.leica-microsystems.com//science-lab/free-webinar-on-demand-digital-microscopy-in-earth-science/ Wed, 30 Aug 2017 11:51:00 +0000 MSc Michael Doppler https://www.leica-microsystems.com/18724 Digital Microscopy How to Analyze Prepared and Unprepared Geological Samples with One Digital Microscope Polarized light microscopes have been used in classical earth science studies for the last 100 years. Since then a lot of progress has been made to increase the user friendliness, ergonomy, and optical performance of such microscopes. Still, one thing has not changed: Classical polarized light (compound) microscopes can only be used for prepared samples, because the working distance they offer is insufficient for whole samples. This article explains how earth scientists can analyze prepared and unprepared samples for polarized light applications with one single instrument, namely the Leica DVM6 M digital microscope. With the right choice of accessories it serves as a semi-quantitative polarization microscope. https://www.leica-microsystems.com//science-lab/how-to-analyze-prepared-and-unprepared-geological-samples-with-one-digital-microscope/ Thu, 18 Aug 2016 07:21:00 +0000 MSc Michael Doppler
