Hidehito Asaoka focuses on impacts of surface stress on reconstruction and nano-structural formation using molecular beam epitaxy (MBE), X-ray photoelectron sectroscopy (XPS), scanning tunneling microscopy (STM).


It is clear that surface stress and surface morphology have a strong relationship. The surface stress results from the microscopic bonding configuration at the surface. The Si reconstructed surface has unique structure based on dangling bonds reduction and adatom formation. Although the rearrangement of the surface atoms largely reduces the electronic energy of surface by reducing the number of surface dangling bonds, the surface reconstruction increases the surface stress and the surface energy as well. Complex arrangements of the surface atoms, such as adatoms, dimers, and stacking faults are formed on Si(111) 7×7, and pair of pentagons are formed on Si(110) 16×2. Despite the importance of the surface energy of Si, the experimental knowledge on the impacts of reconstruction on the Si surface has been quite limited. We have focused on stress measurements during desorption and adsorption process of hydrogen on the Si(111) 7×7 and Si(110) 16×2 surfaces. In order to obtain information on both the surface stress and the surface structure simultaneously, we have combined the surface-curvature and the reflection high-energy electron-diffraction instrumentations in an identical ultrahigh vacuum system.

Metamaterials are rationally designed artificial materials composed of tailored functional building blocks densely packed into an effective (crystalline) material. While metamaterials historically are primarily thought to be associated with negative refractive indices and invisibility cloaking in electromagnetism or optics, it turns out that the simple metamaterial concept also applies to many other areas  of physics namely the thermodynamics, classical mechanics (including elastostatics, acoustics, fluid dynamics and elastodynamics) and in principle also to the quantum mechanics. This lecture will review the basic concepts and analogies behind the thermodynamic, acoustic, elastodynamic/elastostatic, and electromagnetic metamaterials and differences among them. It will provide an overview of the theory, the current state of the art and example applications of various types of metamaterials. The review will also discuss the homogeneous as well as inhomogeneous metamaterial architectures designed by coordinate-transformation-based approaches analogous to transformation optics. The application examples will include laminates, thermal cloaks, thermal concentrators and inverters, anisotropic acoustic metamaterials, acoustic free-space and carpet cloaks, and mechanical metamaterials with negative dynamic mass density, negative dynamic bulk modulus, or negative phase velocity. Finally an example of quantum-mechanical matter-wave cloaking will be provided.

In any manufacturing environment, defects resulting in rework or rejection are directly related to product cost and quality, and indirectly linked with process, tooling, and product design. Thorough of product defects is therefore integral to any attempt at improving productivity, efficiency, and quality. Commercial aluminum extrusion is generally a hot working process and consists of a series of different but integrated operations: billet preheating and sizing, die set and container preheating, billet loading and deformation, product sizing and stretching/roll-correction, age hardening, and painting/anodizing. Product defects can be traced back to problems in billet material and preparation, die and die set design and maintenance, process variable aberrations (ram speed, extrusion pressure, container temperature, etc), and post-extrusion treatment (age hardening, painting/anodizing, etc). The current paper describes some major press-area extrusion product defects, traces their origins and causes, and proposes remedial majors for their prevention and mitigation. Sources of information are published articles from research and trade journals, extensive discussions with practicing engineers in regional extrusion plants, and extrusion research conducted over roughly two decades.

Introduction: Aluminum extrusion is primarily a hot working process with high productivity and low rejection rates. From a defects viewpoint, an extruded profile may either be reworked or rejected. Rejected product is highly undesirable as it leads to material and manhour/ processing loss, in addition to the extra cost required to make up for the rejected items. This rejection may be traced to defective billets, faulty or unsuitable tooling, processing anomalies, post-extrusion defects, and surface finishing defects. For ease of quality assurance and costing activities, the entire setup can be divided into three major cost centers: press area (all activities up to and including age hardening furnaces), anodizing, and painting.

For both extrusion research and industrial practice, it is important to study product defects: their detailed breakdown, their mechanics-based and activity-based classification, their causes and origins, and their preventive/remedial measures. The current paper briefly describes those extrusion product defects that are commonly encountered in the press area of a commercial enterprise.

Defects included in this review are: Die lines. Black Lines. White lines. Scales or blisters. Pick-up defect. Silicon marks. Runout marks. Graphite lines. Die stop marks. Billet-to-billet weld or transverse weld. Stains/oil patches. Twists and bends. Scratches. Damages. Dents. Hot rub marks. Rough surface. Out of angle. Concave or convex or uneven surface. Off dimensions. Uneven wall thickness.
