A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Structural Research on Surface Layers: A Focus on Stability, Surface Layer Homology Domains, and Surface Layer–Cell Wall Interactions

Journal of Structural Biology, 1998
Surface layers (S-layers) from Bacteria and Archaea are built from protein molecules arrayed in a two-dimensional lattice, forming the outermost cell wall layer in many prokaryotes. In almost half a century of S-layer research a wealth of structural, biochemical, and genetic data have accumulated, but it has not been possible to correlate sequence data

The endothelial surface layer

Pflügers Archiv - European Journal of Physiology, 2000
The endothelial lining of blood vessels presents a large surface area for exchange of materials between blood and tissues, and is critically involved in many other processes such as regulation of blood flow, inflammatory responses and blood coagulation.

Multiple angle ellipsometric analysis of surface layers and surface layer contaminants

Applied Optics, 1982
A multiple angle ellipsometric method is used for the measurement of substrates covered by contaminant layers and for the measurement of thin film layers on substrates. The method evaluates the fundamental optical constants N and K of the substrate and film layers deposited on it.

Layer-by-layer surface modification of lipid nanocapsules

European Journal of Pharmaceutics and Biopharmaceutics, 2010
Lipid nanocapsules (LNCs) were modified by adsorbing sequentially dextran sulfate (DS) and chitosan (CS) on their surface by the layer-by-layer (LBL) approach. Tangential flow filtration (TFF) was used in intermediate purifications of the LNC dispersion during the LBL process. The surface modification was based on electrostatic interactions between the

Layer by layer nanoarchitectures for the surface protection of polycarbonate

European Polymer Journal, 2013
Abstract The layer by layer (LbL) technique has been exploited for depositing a completely inorganic silica coating on 0.2 and 1 mm thick polycarbonate (PC) films. The modification of the surface of the polymer substrate has been assessed by contact angle measurements, SEM and FT-IR analyses.

Functionalisation of surfaces with S-layers

IEE Proceedings - Nanobiotechnology, 2004
Two-dimensional bacterial surface layer protein crystals (S-layers) are the most commonly observed cell surface structures in prokaryotic organisms (bacteria and archaea). Isolated S-layer proteins have the intrinsic tendency to self-assemble into two-dimensional arrays in suspension and at various interfaces. Basic research on the structure, genetics,

Surface layers of methanotrophic bacteria

Microbiology, 2013
Structural and functional characteristics of the regular glycoprotein layers in prokaryotes are analyzed with a special emphasis on aerobic methanotrophic bacteria. S-layers are present at the surfaces of Methylococcus, Methylothermus, and Methylomicrobium cells.
