The Ries Crater impact breccia deposits are accessible through a series of boreholes. In 2008, a further hole was cored near the village of Enkingen (SE Ries), accessing the crater breccias at the inner slope of the crystalline ring. The 100 m drill core comprises 21.2 m crater sediment above suevite to )86.24 m and a rather massive impact melt rock to endof-hole [1]. Downhole, the abundance an...

It has been suggested that surface modification with a thin hydroxyapatite (HA) coating enhances the osseointegration of titanium implants. However, there is insufficient information about the biological processes involved in the HA-induced response. This study aimed to investigate the inflammatory cell response to titanium implants with either amorphous or crystalline thin HA. Human mononuclea...

The use of mass spectrometry imaging for crystallinity detection offers improved matrix selectivity and sensitivity over the techniques, such as X-ray microscopy Raman spectrometry, that are traditionally used with this work. Crystallinity is observed in electrospray laser desorption ionization (ELDI-MSI) a high-intensity agglomeration analyte spatially resolved image. As an indirect method det...

Micro chemical tests have been used to aid in the identification of materials and as rapid screening tools for microscopists and forensic chemists for decades. It is generally understood in the microscopy community that these types of tests, with unique resultant crystalline formations, can be quite specific and used for material identification. However, some consider micro chemical tests as se...

The acoustical macro-behavior of mineral open-cell foam samples is modeled from microstructure morphology using a three-dimensional idealized periodic unit-cell (3D-PUC). The 3D-PUC is based on a regular arrangement of spheres allowed to interpenetrate during the foaming process. Identification and sizing of the 3D-PUC is made from x-ray computed microtomography and manufacturing process inform...

INTRODUCTION Bioactive endodontic sealers have been developed to improve the quality of root canal obturation. EndoSequence Bioceramic (BC) Sealer is amongst calcium silicate-based materials recently developed for permanent root canal filling. The objective of this study was to evaluate the bioactivity of BC Sealer and its micro push-out bond strength to dentin compared to AH-Plus (AH) sealer. ...

To study the effects of warm laser peening (WLP) on the thermal stability and mechanical properties of A356 alloy, the samples were treated by WLP using a Nd:YAG solid-state laser and temperature control device. The residual stress, micro-hardness and microstructures of samples treated by WLP were observed. The result shows that the temperature significantly affects the strengthening effect of ...

In this contribution, we present an electron selective passivating contact metallised with a low temperature process to target front side applications in crystalline silicon (c-Si) solar cells. addition interfacial oxide (SiOx) and in-situ phosphorous doped micro-crystalline (?c-Si(n)) layer, it comprises ultra-thin indium tin (ITO) layer of 15 nm for lateral conductivity hydrogen rich nitride ...

Introduction: The presence of crystalline silicates in the co-mae of comets, inferred through infrared astronomical observations , has been a long-standing puzzle (e.g., [1]). Crystalline silicates are unexpected if comets are composed of pristine interstellar material, since interstellar silicates are almost entirely amorphous[2]. Heating to > 1100K can anneal silicates to crystallinity, but n...
