Occurrence of so-called "vein greisens" is one of characteristic features of the Variscan peraluminous granites in the western part of the Krusne hory/Erzgebirge area (Nejdek-Eibenstock Pluton, Horni Blatna body). The "veins" actually represent steeply dipping zones consisting of tens to hundreds of individual roughly parallel cm-To dm-Thick stringers of metasomatic greisen reaching total thickness to several meters, and lengths of hundreds of meters. They mostly consist of quartz and Li-bearing mica with some topaz and cassiterite. Greisens of this type were mined at Prebuz, Rolava and Horni Blatna since the 15th century until 1945. The aim of this study is to distinguish magmatic and hydrother- mal quartz in greisen, i.e. to differentiate relics of the original magmatic quartz from quartz originated hydrothermally during greisenization. We studied a series of samples from the historic mine Streitpingen situated in the Horni Blatna granite body near the village of Potucky. The parent rock of greisens is medium-grained alkali-feldspar granite composed of 40 vol.% quartz, 29 vol.% albite, 20 vol.% perthitic K-feldspar and 9 vol.% Li-enriched biotite with small amount of topaz, apatite, rutile, monazite and zircon (Tables 1, 2). The zone of greisenization is up to 5 m thick and enriched with quartz (87 vol.%) and topaz (9 vol.%). The content of mica decreased to 3 vol.% and both feldspars disappear. Greisen is penetrated by monomineralic up to 10 cm thick quartz veins (> 97 vol.% quartz) with abundant tiny cavities. Veins are composed of clear long columnar crystals (5 mm diam., up to 5 cm long) which are coated with a thin layer (∼ 1 mm) of milky white quartz. For comparison, we analyzed also quartz from quartz-Tourmaline fillings of miarolitic cavities (5-10 cm diam.) in granite, traditionally called as "tourmaline suns", which are widespread in the central and northern parts of the Nejdek-Eibenstock Pluton (Schust etal. 1970). Internal structure of analyzed quartz grains visualized by cathodoluminescence (CL) is shown in Figs 1 and 2. Trace elements in quartz were analyzed using laser-Ablation ICP-MS (for detail of the method used see Breiter et al. 2013). Average contents of the analyzed element in selected quartz crystals are shown in Table 3, all the individual analyses of selected elements are shown in Fig. 4. Contents of Al, Ti, and Li across selected crystals are given in Fig. 5; position of these profiles is shown in Figs 2b, c and 3. Aluminum, Li, and Ti are the most abundant trace elements in quartz. The content of Al in phenocysts of magmatic quartz and quartz from tourmaline suns corresponds roughly to 400 ppm (range 300-500 ppm), whereas only 115-270 ppm were found in the greisen quartz. The Al-contents in hydrothermal quartz strongly fluctuate: The clear domains contain 50-340 ppm Al, while 500-2400 ppm were detected in cloudy crystal cores, and 1100-4800 ppm Al in the milky white crystal rims. Content of Ti in magmatic quartz fluctuates between 40 to 100 ppm with extreme values up to 200 ppm near the margins of some crystals. Quartz from tourmaline suns contains 10-40 ppm Ti, while quartz from the greisen approximately 20 ppm Ti, and the hydrothermal quartz from veins generally contains < 1 ppm Ti. The contents of Li in magmatic quartz and quartz from tourmaline suns range between 30-50 ppm. Contents of Li in quartz from greisen and clear domains of hydrothermal quartz are rather smaller, approximately 10-30 ppm. The highest Li-values in the range of 70-170 ppm were found in the milky hydro-Thermal quartz. The contents of Li and Al reveal positive correlation. Our preliminary research has shown that quartz originated dur-ing metasomatic greisenization differs from the primary magmatic quartz by lower intensity of cathodoluminescence and significantly lower concentrations of trace elements Al, Ti, and Li. Quartz from quartz-Tourmaline filling of miarolitic cavities is chemically similar to the magmatic phenocrysts. The low-Temperature hydrothermal quartz shows a strong zonal structure in CL, has low content of Ti, and highly variable concentrations of Al and Li.

The aim of the study was to prepare PLGA microparticles for prolonged release of mirtazapine by o/w solvent evaporation method and to evaluate effects of PVA concentration and organic solvent choice on microparticles characteristics (encapsulation efficiency, drug loading, burst effect, microparticle morphology). Also in vitro drug release tests were performed and the results were correlated with kinetic model equations to approximate drug release mechanism. It was found that dichloromethane provided microparticles with better qualities (encapsulation efficiency 64.2%, yield 79.7%). Interaction between organic solvent effect and effect of PVA concentration was revealed. The prepared samples released the drug for 5 days with kinetics very close to that of zero order (R2= 0.9549 - 0.9816). According to the correlations, the drug was probably released by a combination of diffusion and surface erosion, enhanced by polymer swelling and chain relaxation. © 2014 Informa Healthcare USA, Inc.

The role that organelle analysis has played in understanding biology is studied. Organelle analysis enables a more specific description of the molecular, biochemical, and physiological processes associated with diseases, embryonic development, tissue differentiation, organism aging, disease treatments, and organism response to pathogens. Confocal microscopy has become a routine tool for investigating subcellular organization, organelle networks, and organelle dynamics in cellular and tissue samples. Most organelles have a dynamic, three-dimensional (3D) organization inside the cell, which is tightly connected to their physiological functions. Due to this, a single 2D image inherently limits the information acquired about the distribution of a particular property within the organelle. The combination of subcellular fractionation with 'omic' technologies has become a powerful resource to characterize and catalogue the various subcellular environments in a cell.

A novel field-emission SEM column has been developed that features Beam Deceleration Mode, high-probe current and ultra-fast scanning. New detection system in the column is introduced to detect true secondary electron signal. The resolution power at low energy was doubled for conventional SEM optics and moderately improved for immersion optics. Application examples at low landing energies include change of contrast, imaging of non-conductive samples and thin layers. © 2014 Elsevier B.V.

3D tomography of TSVs was performed by combining Xe plasma FIB milling and lift-out techniques. This approach allows analyzing the structure of TSVs in detail using a method faster than the usual 3D tomography by Ga FIB and more precise than X-ray tomography. Both well-filled TSVs and TSVs with voids were analyzed and the results were compared. The analysis procedure was optimized in order to reduce the analysis time and to increase the throughput. The lift-out of the analyzed block of material was performed to obtain 90° angle between TSV and the ion beam axes, which is critical to reduce the curtaining effect and which allowed to increase FIB beam current significantly, reducing the analysis time.

Tescan, Czechoslovakia, will present a webinar on "Failure analysis of Microelectronic Devices" Wednesday May 4 at 9 am EDT. In this webinar, recent achievements in advanced failure analysis in state-of-the-art microelectronic devices will be presented. The presentation is divided into two parts. The first part will include FA results on integrated circuits based on state-of-the-art 14-nm node technology. The focus will be on well-controlled orthogonal and planar IC delayering using gas-assisted Xe plasma FIB etching The second part will cover FA results on advanced packaging technologies using Xe plasma FIB. It will show how TEM lamellae are prepared with Ga and Xe plasma FIB. Particular attention will be paid to the preparation of front- and back-side artifact-free lamellae. Cross-sections with dimensions exceeding 100 µm will be demonstrated, emphasizing the mitigation of FIB artifacts using the proprietary Rocking stage technology and special masking methods. These approaches allow for processing of even the most challenging packages.
