The industrialization of perovskite solar cells (PSC) require processes to efficiently deposit the constituent layers over large areas. In this work we optimized the use of slot die coating process for both sheet-to-sheet (S2S) and roll-to-roll (R2R) manufacturing. Particular focus have been put on the control of the uniformity of perovskite...

The preparations for the design and construction of the Extremely Large Telescope (ELT) are in full swing. One of the most critical components of this enormous telescope is its segmented primary mirror (M1), for which Netherlands Organisation for Applied Scientific Research (TNO), in collaboration with VDL, has designed the mechanical segment...

Vehicle dynamic simulations require accurate, fast, reliable, and easy-to- parameterize tire models. For this purpose, TNO developed MF-Swift in close cooperation with the technical universities of Delft and Eindhoven. MF-Swift is based on the well-known magic formula model of Pacejka but extending to higher frequencies (60-100 Hz), shorter...

Miniaturization of biosensors is envisaged by the development of biochips consisting of parallel microarray patterns of binding sites on rigid substrates, such as glass or silicon. Thin plastic substrates are promising flexible alternatives because of the possibility for large-area roll-to-roll manufacturing of disposable chips at lower costs....

Background: Damage to articular cartilage is one of the features of osteoarthritis (OA). Cartilage damage is characterised by a net loss of collagen and proteoglycans. The collagen network is considered highly important for cartilage function but little is known about processes that control composition and function of the cartilage collagen...

The effect of ovalbumin net charge on aggregate morphology and visual properties was investigated using chromatography, electrophoresis, electron microscopy, and turbidity measurements. A range of differently charged ovalbumin variants (net charge ranging from -1 to -26 at pH 7) was produced using chemical engineering. With increasing net charge...

Jacketed penetrators of mid calibre type have been produced by explosive cladding of various jackets on two different kinds of tungsten heavy alloy (WHA) rods. The jackets, of different thicknesses, were made of steel-37, stainless steel 316L, titanium grade (2, 3) and pure titanium grade 2. The jacket increased the flexural rigidity of the core...

In this paper, an overview of the TNO MF-SWIFT model is given. After an historical overview of the model development and the intended range of application, the model is described briefly. Next, the implementation in multibody and other simulation software is discussed, including also the available road models. After that, the parameterization of...

Objective: Examine effects of insulin-like growth factor 1 (IGF1), transforming growth factor β2 (TGFβ2) and fibroblast growth factor 2 (FGF2) on proteoglycan and collagen network and biomechanical properties of the newly formed cartilage matrix. Methods: Bovine articular chondrocytes were cultured in alginate beads for 3 weeks with or without...

Fibroblast growth factor (FGF) receptor 3 has been identified as a key regulator of endochondral bone development and of post-natal bone metabolism through its action on growth plate chondrocytes and osteoblasts, respectively. It has also been shown to promote chondrogenesis and cartilage production by cultured pre-chondrogenic cells in response...

Central and peripheral fatness seem to confer opposite (i.e. adverse vs. protective) effects on cardiovascular risk, but how this occurs is not clear. In addition, the role of peripheral lean mass needs to be elucidated. We therefore investigated, in 336 (175 women) 36-yr-old and apparently healthy adults, the relationship between trunk fat,...

Objective: To determine whether avoidant coping in ankylosing spondylitis (AS) is independent of disease status and whether it is stable over time. Methods: 658 patients with AS completed a postal questionnaire on health status, including pain and stiffness (BASDAI), physical function (BASFI), and coping (CORS). In CORS, "decreasing activities...

Purpose of review: Across the world, osteoarthritis is the most commonly occurring musculoskeletal disease of the elderly, affecting more than 25% of the population older than 60 years of age. By far the single greatest risk factor for the development of osteoarthritis is age, but a mechanism to explain this relation has not yet been identified....

Formation and structure of glycinin gels were studied in relation to protein conformation for two pH values and three ionic strengths. While at I = 0.03 the gels were found to be fine stranded, gel coarseness increased when the ionic strength was higher. At I = 0.03 finer gel network structures were formed at pH 3.8 than at pH 7.6, whereas for I...

Objective. To determine whether increasing advanced glycation end products (AGEs) in bovine articular cartilage to levels present in aged human cartilage modulates the tensile biomechanical properties of the tissue. Methods. Adult bovine articular cartilage samples were incubated in a buffer solution with ribose to induce the formation of AGEs...

The purpose of this study was to explore the relationship between the integrity of collagen and biomechanical properties of bone. In this study, age (range, 5-26 years old) and gender related changes in cortical bone samples from 33 baboon femurs (15 males and 18 females) were examined. The percentage of denatured collagen was determined using a...

Mathematical modelling of the human body is widely used for automotive crash safety research and design. Simulations have contributed to a reduction of injury numbers by optimisation of vehicle structures and restraint systems. Currently such simulations are largely performed using occupant models based on crash dummies. These models inherit the...

We have studied the relationship between the apolipoprotein E gene (APOE) and the development of myoclonus, tremors, rigidity and seizures in 168 patients with probable early-onset Alzheimer's disease (AD). There was a statistically significantly lower risk of tremor for carriers of the ε4 allele of APOE. This allele was also associated with an...

When holography is applied outside the laboratory, problems are encountered such as vibrations, rigid-body motion, and stray daylight. Pulsed holography can overcome the difficulties with vibrations, but the other problems are less easily solved. When the object area to be holographically tested is small, a simple and convenient method may be...
