The development of a Single Photon Source (SPS) prototype is discussed here which has the ability to efficiently produce polarized single photons on demand. The SPS prototype is to be of a relatively moderate size in order to be mass produced industrially and marketed as a ”Single Photon Gun” (SPG). The size and reliability of the SPG is of critical importance in meeting the needs of the curren...

Behaviour in a Dynamic In Vitro Dissolution Model A. Goyanes, H. Chang, A. Buanz, J. Wang, S. Gaisford, A. W. Basit University College London Purpose 3-dimensional printing (3DP) is a new technology which could potentially revolutionise the future of pharmaceutical manufacturing. In fused-deposition modelling (FDM) printing, a polymer filament is heated and extruded through a small tip and soli...

As an atomically thin sheet of carbon atoms packed in a twodimensional (2D) honeycomb lattice with excellent electronic, thermal, and mechanical properties, graphene has shown great potential for a wide range of applications. Examples include the use of graphene and its derivatives as transparent conductive electrodes or active materials in solar cells, counter electrodes in dye-sensitized sola...

This study presents a new decision making method for scheduling paper mill processes, especially for the paper converting process. The optimal scheduling is analyzed with the multiobjective optimization programming (MOOP) using the summation of weighed objective functions (SWOF) [Ko and Moon, 2002]. In the production planning for the paper converting mill, making the strategy for the cutting pa...

The goal of this work is to demonstrate that high performance solar reflective material can be produced in a roll format using vacuum deposition techniques. The material consists of a multilayer thin film stack on a substrate. The essential feature of the film stack is an alumina film several microns thick deposited over a silver film. The alumina film is deposited under high vacuum using a phy...

Image-based particle tracking methods have numerous applications in biological studies at the cellular and molecular level. For example, tracking thermal motions of micron-sized spherical particles embedded in the cell cytoplasm reveal microheterogeneity of cellular rheology (1). Fluorescent microspheres conjugated with protein analogs as well as colloidal gold beads have been used to study mob...

A laser opto-microactuator has been proposed as an Optical Micro-Electro-Mechanical-Systems (OMEMS). The rotational or twisting mechanisms of the microactuator have been discussed. For increasing the sensitivity of the actuator, the temperature difference between the front and rear blade surfaces of the actuator should be increased. Therefore, high absorption rates on the blade surface with las...

b adsorbed on surfaces that can enhance the absorption and emission of electromagnetic radiation. Surface-enhanced Raman scattering (SERS) is a wellinvestigated phenomenon and an established surface analytical tool (1). The surface enhancement of infrared spectra was first observed and investigated by Hartstein et al. in 1980 (2a), but it is still developing and has not yet matured into a relia...

A computational method is presented for analyzing free surface flows of polymer solutions with the conformation tensor. It combines methods of computing Newtonian free surface flows [J. Comp. Phys. 99 (1992) 39; V.F. deAlmeida, Gas–Liquid Counterflow Through Constricted Passages, Ph.D. thesis, University of Minnesota, Minneapolis, MN, 1995 (Available from UMI, Ann Arbor, MI, order number 961516...
