The genesis of Mordenite occurrences: Diagenetic and hydrothermal alteration processes of Paleocene volcanics in Ilıca (Yıldızeli), Türkiye

open access: yesBulletin of the Mineral Research and Exploration
Different geological processes such as weathering, diagenesis in hydrological systems, hydrothermal processes and contact metamorphism have been proposed to explain the genetic relationships of mordenite occurrences.

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Defining Mineral Exploration Works

open access: yesProcedia Earth and Planetary Science, 2015
AbstractWhen mineral exploration starts, a number of problemshave to be dealt with. They refer to the density of sampling (samples, drill-holes, drifts) so as to have a reliable estimation of the reserves, the decision to extend the exploration campaign, especially with works of high cost, when the first results are interesting and, of course, the risk

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

open access: yesAdvanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...
