Thin Ceramic Coatings and Their Suitability Towards Scale Reduction in Heat Exchangers

Santos O., Nilsson M., Jensen A.H., Christiensen, A.B., Alfa Laval AB, SE

Scaling of heat exchangers in the chemical industry, district heating, power plants, etc results in a loss of performance which leads to production stops for cleaning and therefore increased operation costs. One approach to mitigate [...]

Multiple gate approach – solution of scaling and nano MOSFETS

Lamba V.K., Engles D., Malik S.S., Haryana College of Technology & Management,Kaithal, IN

In the sub-50nm scale, the aggressive scaling of MOSFETs is expected to culminate in dual-gate (DG) architectures on SOI substrates. DG MOSFETs are widely accepted to be the ultimate design that silicon can deliver in [...]

Nano-structure or nano-system: opportunities and pitfalls

French P., Delft University of Technology, NL

Scaling down has revealed many new effects leading to new devices able to measure faster and more accurately than traditional devices. They also present challenges in terms of connecting to the macro-world and in reliability. [...]

The Relationship Between Nanoscale AFM Adhesive Force Measurements using Calcite Crystals with Macroscale contact angle and Scaling Characteristics

Boyd R.D., Bargir S., Dunn S., Jefferson B., Cranfield University, UK

The growth of scale, which primarily consists of calcite crystals, is a major problem in water systems. AFM probes have been modified with calcite crystal in order to measure the strength of adhesion between the [...]

Compact, Physics-Based Modeling of Nanoscale Limits of Double-Gate MOSFETs

Chen Q., Wang L., Murali R., Meindl J.D., Georgia Institute of Technology, US

Compact, physics-based models of subthreshold swing and threshold voltage are presented for double-gate (DG) MOSFETs in symmetric, asymmetric, and ground-plane modes. Applying these device models, threshold voltage variations in DG MOSFETs are comprehensively and exhaustively [...]

Scaling of Electroosmotic Flow and Ionic Conductivity in Nanochannels

Qiao R., Aluru N.R., Beckman Institute for Advanced Science and Technology, US

Electrokinetic transport is widely encountered in many nanofluidic systems, and understanding its scaling as a function of various operating conditions, e.g., bulk concentration, is important for establishing design rules and for exploring the design space. [...]

Numerical Simulation of Microfluidic Flow Using a Combination of Micro and Macro Computational Techniques: Scaling Issues

Mautner T., SPAWAR Systems Center San Diego, US

Recent literature has demonstrated the possibilities of using configurable surfaces to enhance the flow of fluids in MEMS devices. Not only are surface properties important in fluid delivery, the inherent problems of mixing by diffusion [...]

Scaling Behavior of Pressure-Driven Micro-Hydraulic Systems

Tas N.R., Lammerink T.S.J., Berenschot J.W., Elwenspoek M.C., van den Berg A., University of TWente, NL

This paper presents a lumped network approach for the modelling and design of micro-hydraulic systems. A hydraulic oscillator has been built consisting of hydraulic resistors, capacitors and transistors (pressure controlled valves). The scaling of micro-hydraulic [...]

New Numerical Techniques and Tools in SUGAR for 3D MEMS Simulation

Bai Z., Bindel D., Clark J., Demmel J., Pister K., Zhou N., University of California Davis, US

SUGAR is a modified nodal analysis package for 3D MEMS simulations that owes its heritage and its name to the SPICE family of circuit simulation. SUGAR has undergone the stage of proof-of-concept which showed that [...]
