Characterization of a novel personal aerosol measurement device

Fine particulate air pollution is recognized as causing health problems globally, but health researchers are just starting to understand where people receive their exposure, which will influence policies and regulations. There is a need for size-resolved particle measurements using a device that can be carried easily by a person. Nanozen has built such a device, and it could be used also for workplace ventilation control. However, first the sensor response to a wide range of particle sizes and compositions must characterized.

Powder Morphology Effect Assessment on Cold Spray Process for Repair and Additive Manufacturing Applications

Cold Spray is a coating additive manufacturing process relying on the particle kinetic, with particles plastically deforming upon impact with the substrate and adhering to it. While the production of thin aluminum/aluminum alloys coatings (below 1mm) by Cold Spray is fairly common, the production of thick coatings (> 1mm) and large net-shape parts has been more challenging. Equispheres patent-pending atomization technology produces free-flowing, uniform spherical metal powders, with narrow particle size distribution, excellent sphericity and flowability.

Framework Design and Prototyping of a Personal Task and Time Management Mentor Package with A Dynamic, Multi-facet, Data-oriented and Associative Engineering Management Method

There have been many new operational drivers that require changes to the traditional training processes in small and medium companies, i.e. the advancement of technology, the mass retirement of the baby boomer generation, and the ever more dynamically-changing values of the web-generation workforce. Dealing with bridging the skill gaps may deem to uproot the company paradigm and demand for a new and more efficient model. Is there a solution to reduce the growing pain of workforce renewal?

Structural design of aerospace composites with Hybrid Fibre Architectures

Continuous fibre (CF) aerospace preforms exhibiting excellent mechanical performance possess low formability characteristics and are confined to simple shell-like geometries with minimal curvatures. On the other hand, short fibre preforms such as randomly oriented strands (ROS) offer high formability but exhibit low mechanical performance. The manufacturing of composites involves time and huge costs.
