Topographical analysis of the primer cup of both fired and unfired ammunition was done. The ammunition was fired from revolvers in 3 orientations: horizontal, vertically upwards, and vertically downwards. The degree in variability of flattening on the primer cup, of depth of the firing pin impression, and the discernibility of individual characteristics in the three firing conditions were determined. https://www.leica-microsystems.com/topographic-analysis-of-firing-pin-impressions-on-cartridge-cases/ Fri, 29 Jan 2021 12:32:00 +0000 MSc Valentina Manzalini, PhD James DeRose, Giancarlo Parma, PhD Valerio Causin https://www.leica-microsystems.com/11641 Surface Metrology Quality Assurance Brief Introduction to Surface Metrology This report briefly discusses several important metrology techniques and standard definitions commonly used to assess the topography of surfaces, also known as surface texture or surface finish. With the advent of nanotechnology, thin coatings, and the miniaturization of circuits and devices, surface metrology has become an extremely important field of science and engineering. https://www.leica-microsystems.com/science-lab/brief-introduction-to-surface-metrology/ Wed, 06 Nov 2019 08:27:00 +0000 PhD James DeRose, M.S.

Barbero https://www.leica-microsystems.com/13490 Surface Metrology Characterization of Thin Films Using High Definition Confocal Microscopy Thin film characterization technologies are in high demand, given the wide-spread use of coatings in all engineering and science fields. The properties of thin films can vary dramatically, i.e. thickness, optical and electrical properties, hardness, etc., that is difficult to find a general purpose characterization technique. https://www.leica-microsystems.com/science-lab/characterization-of-thin-films-using-high-definition-confocal-microscopy/ Thu, 05 Jun 2014 10:52:00 +0000 MSc Marco Renzelli, PhD Edoardo Bemporad https://www.leica-microsystems.com/13105 Surface Metrology Digital Microscopy An Innovative Non-contact Method to Determine Surface Free Energy on Micro-areas Surface free energy (SFE) is a property which depends on the chemical state and roughness of the surface and it is necessary to develop a reliable method to evaluate SFE value on a small area, taking into account these two different contributions. Today contact angle methods are the most used and they allow to evaluate the global mean value of SFE on areas of mm2 size. https://www.leica-microsystems.com/science-lab/an-innovative-non-contact-method-to-determine-surface-free-energy-on-micro-areas/ Mon, 28 Apr 2014 16:41:00 +0000 https://www.leica-microsystems.com/12785 Surface Metrology Digital Microscopy Quality Assurance Surface Roughness of Flowable Resin Composites eroded by Acidic and Alcoholic Drinks Acidic beverages, such as soft drinks (orange juice, and cola), or ethanol (whisky), can produce erosion of resin composites. The surface degradation of resin materials is related to the content and distribution of the fillers, the composition of the matrix resin, and the effect of silane surface treatment on the fillers. https://www.leica-microsystems.com/science-lab/surface-roughness-of-flowable-resin-composites-eroded-by-acidic-and-alcoholic-drinks/ Thu, 24 Apr 2014 20:51:00 +0000 https://www.leica-microsystems.com/12648 Surface Metrology Quality Assurance Digital Microscopy The Effects of Peri-implantitis Decontamination Treatments on the Surface Roughness and Chemistry of a Titanium Alloy Used for Dental Implants: Implications for Bone Reintegration Titanium (Ti) alloys are biocompatible materials which are often used for human implants, especially in dentistry. For this study, different types of odontological (dental) treatments for peri-implantitis, an infection of the gum and dental tissue around the implant, were performed on a Ti-6Al-4V (TAV) alloy, typically used for implants, to study the effect on its surface roughness and chemistry. https://www.leica-microsystems.com/science-lab/the-effects-of-peri-implantitis-decontamination-treatments-on-the-surface-roughness-and-chemistry-of-a-titanium-alloy-used-for-dental-implants-implications-for-bone-reintegration/ Wed, 19 Feb 2014 11:22:00 +0000 PhD Jordi Diaz-Marcos, MSc Joan Vilana Balastegui, DDS, MS, PhD Angel F.
