Development of a novel flat pneumatic artificial muscles with minimal normal expansion: An explorative design study

Artificial Muscles (AMs) are often used as the actuation source for soft robots. AMs demonstrate great power-to-weight ratios, are generally compliant and therefore a safe mode of actuation in human-machine interfaces. Flat Pneumatic Artificial Muscles (FPAMs) are a subgroup of AMs and are designed to contract once pressurized. They are low...

Modeling the M2 and M4 tidal wave propagation subjected to deepening, widening and friction change in an one dimensional basin system

River estuaries are strongly modified by human interventions, such as dredging. For example the Ems river (Germany and Netherlands) has been deepened between in 1965 and 2005. As a result the sediment (sand and dirt) concentration has increased enormously \cite{Ems_data}. The muddiness of this sediment blocks sunlight and decreases the friction...

Engineered cell culture microenvironments for mechanobiology studies of brain neural cells

The biomechanical properties of the brain microenvironment, which is composed of different neural cell types, the extracellular matrix, and blood vessels, are critical for normal brain development and neural functioning. Stiffness, viscoelasticity and spatial organization of brain tissue modulate proliferation, migration, differentiation, and...

Flavin-dependent N-hydroxylating enzymes: Distribution and application

Amino groups derived from naturally abundant amino acids or (di)amines can be used as “shuttles” in nature for oxygen transfer to provide intermediates or products comprising N-O functional groups such as N-hydroxy, oxazine, isoxazolidine, nitro, nitrone, oxime, C-, S-, or N-nitroso, and azoxy units. To this end, molecular oxygen is activated...

Precise and reversible band gap tuning in single-layer MoSe2 by uniaxial strain

We present photoluminescence (PL) spectroscopy measurements of single-layer MoSe2 as a function of uniform uniaxial strain. A simple clamping and bending method is described that allows for application of uniaxial strain to layered, 2D materials with strains up to 1.1% without slippage. Using this technique, we find that the electronic band gap...

An integrated approach for efficient biomethane production from solid bio-wastes in a compact system

Background Solid bio-wastes (or organic residues) are worldwide produced in high amount and increasingly considered bioenergy containers rather than waste products. A complete bioprocess from recalcitrant solid wastes to methane (SW2M) via anaerobic digestion (AD) is believed to be a sustainable way to utilize solid bio-wastes. However, the...
