Microreactors for the Production of Hydrogen From Ammonia
… especially in mobile applications where monolithic structures are advantageous. The best-performing microreactor converts approximately 99% of ammonia at 600°C into the equivalent of 60 W of hydrogen, which is enough to power a laptop computer if the reactor is coupled to a PEM fuel …

Topology optimization with manufacturable multi-material primitives
… Traditionally, optimization focuses mainly on monolithic structures but recently, developments have been made toward determining algorithms for multi-material optimization. A preexisting algorithm is modified to broaden the type of design possible with the method. The algorithm uses a …

Pharmaceutical tablet compaction : product and process design
… fracture at strains less than 5%, forming monolithic structures with no evidence of initial granule shape or size. Pore size decreases as compaction force is increased for DCL 11 tablets. A decreasing pore size corresponds to increasing THz refractive index, tablet hardness and dissolution …

Modification of glasses and optical waveguides using high electric fields
… poled novel high-index bismuth-borate glass structures. According to the rectification model, glass with higher χ(3) values than silica would permit χ(2) to scale up proportionally, for a given frozen-in electric field strength. The fundamental research on poling induced nonlinearity has been …

Nanophosphor-based Photonics
… The work addresses the fabrication of photonic structures with these nanoparticles to modify their emission properties. From a processing point of view, three novel techniques are covered. First, thermal treatment using ultrafast annealing methods is studied, which significantly reduces the time …

Analysis and design of rapid prototyped mechanisms using hybrid flexural pivots
… complexity require them to be manufactured as monolithic structures using conventional precision machining and electro discharge machining (EDM). However, such an approach is expensive and not practical for mass production. They can only be used for custom and high-value added applications. …

Review of codes of practice for the design of box culverts for recommendation for South African Bureau of Standards (SABS)
… the analysis. Box culverts are designed as rigid monolithic structures to withstand the maximum bending moment and shear force. The design involves the analysis of the various loads acting on the culvert with the weight of the overhead earth embankment being the most significant. The vertical …

Preparation, characterisation and modification of porous carbon monolithic materials for chromatographic and electrochemical applications
… attention in recent years is the use of monolithic columns. Monolithic stationary phases for use in liquid chromatography possess unique characteristics, the most significant of which is a relatively high flow through porosity leading to low column pressure drops, with the potential for …

Partial and Total Oxidation of Methane in Monolithic Catalysts at Short Contact Times
… catalysts exhibiting a simple geometry such as monolithic structures are used. The reactor consists of a 40 cm long quartz tube with varying inner diameters. Honeycomb catalysts coated with Rh, Pd, or Pt are placed inside. The gas temperature at the exit of the catalytic monolith and outside the …
