Lean manufacturing is playing a key role in helping a molding company to operate and survive under adverse economic conditions, as it eliminates waste from the manufacturing process. Research conducted by the Lean Enterprise Research Center (LERC) reveals that up to 60% of production activities in a manufacturing process are waste. Lean manufacturing follows the total productive maintenance (TPM) approach to identify and maximize the operational efficiency of equipment and employees. A properly implemented TPM program can increase up-time, reduce cycling time and reduce defects, while improving worker safety at the same time. The first step in establishing TPM is to do an overall assessment of the process, ranging from receiving the order to shipping and everything in between. A strategy to implement a TPM is also dependent on the available resources. Source

The growth and optoelectronic properties of core-shell nanostructures are influenced by the strain induced by the lattice mismatch between core and shell. In contrast with planar films, nanostructures contain multiple facets that act as independent substrates for shell growth, which enables different relaxation mechanisms. In this study, X-ray diffraction data are presented that show that InGa1-N shells grown on GaN cores are strained along each of the facets independently. Reciprocal space maps reveal multiple Bragg peaks, corresponding to different parts of the shell being strained along the individual facet planes. The strained lattice constants were found from the positions of the Bragg peaks. Vegard's law and Hooke's law for an anisotropic medium were applied in order to find the composition and strain in the InGaN shells. A range of nanowire samples with different InGaN shell thicknesses were measured and it is concluded that, with an In concentration of around 30%, major strain relaxation takes place when the thickness reaches 2314nm. InGaN shells of 6 and 914nm thickness remain nearly fully strained biaxially along each of the facets of the nanowires and the facets of the nanopyramids. © 2015 International Union of Crystallography.

Method and device for emitting an illuminated water stream. According to one embodiment, the device includes a liquid stream generator for emitting at least one continuous liquid stream and an illumination device for emitting light. The liquid stream generator and the illumination device are arranged relative to one another so that light emitted from the illumination device is directed into at least one of the at least one continuous liquid stream at an angle such that at least one of the at least one continuous liquid stream is illuminated under the principle of total internal reflection. The liquid used to make the at least one continuous liquid stream may include water and at least one additive, such as a viscosity thickener and a light-diffusing agent.

The suggested project aims at developing a nanowire (NW) technology applied to III-nitride and III-V materials to improve the present Solid State Lighting (SSL) solutions. Present white light emitting diode (LED) emitters are based on thin film III-nitride technology, and a combination of violet-blue LEDs and suitable phosphor coatings has yielded a light emission efficacy of > 100 lm/W with an operating lifetime > 50000 hrs in commercial white LEDs. The color rendering is generally unsatisfactory, however, and the cost is so far prohibitive for general market penetration. Our NW approach is based on combining three (blue-green-red) or four (blue-green-yellow-red) single NW LEDs into one white LED package, thereby avoiding the loss in the phosphor downconversion process. Using NW LEDs we also expect to increase the radiative efficiency due to a drastic reduction of the defect density in the active quantum well (QW) regions of the LEDs, and also improve the extraction efficiency of the emitted light. Our suggested employment of large size silicon or sapphire wafers as substrates is predicted to reduce the future fabrication cost by at least a factor 3. To increase the efficiency of white emitters it is necessary to drastically improve the LEDs emitting in the green-yellow part of the spectrum. We suggest to reach the green LED range by the ability to increase the In composition in the radial QWs of the presently grown nitride NW LEDs, and by using AlGaInP materials. The latter material system will also be explored for yellow and red NW LED emission. To realize yellow-red emission quantum dot media will also be employed, either by the SK growth mechanism on the m-plane facets of the NWs, or by separate application of InP/ZnS core-shell dots with red emission. To realize this work a consortium of five partners is suggested, comprising excellent expertise in growth of NWs and in sophisticated studies of structural, electronic and optical properties of the NWs, and also processing into efficient LED structures having long life-times. The safety issues in the growth and handling of NWs are secured in collaboration with the Nano-Safety project at ULUND. The materials used are favorable from the environmental point of view.
