De Obernkirchener zandsteen, in oude bouwrekeningen vaak als Bremer steen aangeduid, is afkomstig van de Bückeberge tussen Minden (Westfalen) en Hannover. De zandsteen is afgezet in het Onder-Krijt (Berriasiaan) en leent zich goed voor fijn geprofileerd werk. De steen wordt sinds de 11e eeuw gebruikt in de eigen regio. Getransporteerd over de...

Additive manufacturing (AM) methods and post processing techniques are promising methodologies considering that it is now possible to print in a wide variety of materials using processes much refined from those originally available twenty years ago. To date the uptake of AM in Astronomy is relatively low compared to other application areas,...

Commercial, ready mix stone repair mortars have often been applied in conservation practice for the restoration of natura! stone, brick and terracotta, over the last decades with varying success in terms of durability of the repair mortar itself and compatibility with the substrate. In this research, four commercial stone repair mortars,...

Although corrosion of reinforcement is a well-known issue for the construction industry, there are still open questions about some fundamentals of corrosion in reinforced concrete. These points include, among others, which are the most sensitive locations of the steel/concrete interface for pitting corrosion to initiate and to propagate. In this...

In recent years, the amount of research being performed in the field of additive manufacturing of energetic materials has increased tremendously. Many institutions across the globe are developing new materials and techniques for 3D-printing of propellants, thermites, explosives, etc. Groven and Metzger [1] provide an excellent overview of recent...

Cement paste is the glue that holds concrete together and any improvements in material performance will come from its microstructure. For better understanding and predicting its elastic properties and fracture performance, more and more studies are carried out based on micromechanics simulations. However, the predicted results can be hardly...

Steenreparatiemortels zijn mortels die in de conserveringspraktijk worden gebruikt om ontbrekende delen van baksteen of natuursteen in metselwerk of beeldhouwwerk aan te vullen. In de Nederlandse conserveringspraktijk worden steenreparatiemortels regelmatig gebruikt met wisselende resultaten, zowel qua compatibiliteit met het bestaande als qua ...

Metallization of the front contact can increase the conductivity. We show the optical benefit by combining nanowire with a texture of the thin film stack. The parallel nanowires are placed in crevices of a texture in the optical model. Texturization reduces the reflection of both the stack and the nanowire. For a period of 500 nm, the reflection...

Unpackaged CIGS solar cells were simultaneously exposed to illumination and either dry heat, damp heat or dry cold followed by thermal cycling. In-situ monitoring of their electrical parameters demonstrated a rapid decrease of the efficiency for the solar cells exposed to damp heat plus illumination. This decrease was mainly driven by changes in...

The proper long term operation of organic electronic devices like organic photovoltaics OPV depends on their resistance to environmental influences such as permeation of water vapor. Major efforts are spent to encapsulate OPV. State of the art is sandwich-like encapsulation between two ultra-barrier foils. Sandwich encapsulation faces two major...

De Noordersluis bij IJmuiden is één van de grote infrastructurele werken in vooroorlogs Nederland, uitgevoerd in beton (Fig. 1). De bouw van de nieuwe sluis was onderdeel van een reeks verbeteringen aan het Noordzeekanaal: In 1909 was een staatscommissie ingesteld '(om)dat opnieuw de vraag rees of de belangen van Nederland in het algemeen en van...

In this manuscript we present the first successful application of a spatial atomic-layer-deposition process to thin film solar cells. Zn(O,S) has been grown by spatial atomic layer deposition (S-ALD) at atmospheric pressure and applied as buffer layer in rigid and flexible CIGS cells by a lab-scale (15x15 cm2) S-ALD set-up. We achieved values of...

Copper-indium-gallium-di-selenide (CIGS) is the present record holder in lab-scale thin-film photovoltaics (TFPV). One of the problems of this PV technology is the scarcity of indium. Multi-junction solar cells allow better spectral utilization of the light spectrum, while the required current generation per layer is much lower, allowing much...

Tribological properties of materials used in biomedical implants will critically affect the performance of the implant. Ultra-high molecular weight polyethylene (UHMWPE) material is popular due to its great properties. Surface texturing is one of the methods to minimize friction and wear. In this study, the effect of surface texturing on the...

In this work we studied the deposition of silver (Ag) by spatial-ALD on molybdenum layers serving as a growth model substrate. Mo-layers were selected for testing the suitability of spatial-ALD in fabricating MoO3/Ag/MoO3 tri-layer transparent conductor (TC) stacks used for light-management optimization in organic-based and perovskites solar...

This workstudies the impingement on the rim of acetabular liner due to wear on the surface of acetabular liner using finite element simulation. A three dimensional contact model between a femoral head and an acetabular liner was developed. There are three steps in this simulation, i.e. creating the virtualwear on the surface of acetabular liner,...

Failures of mooring lines on floating production, storage and offloading systems (FPSOs) raise concern to the offshore industry. Localized corrosion of mooring chain is regarded as one of main failure mechanisms. The project of Localized Mooring Chain Corrosion (LMCC) is aiming at studying the mechanism of local corrosion on mooring chain steel...
