Additive “4D” Rheoprinting for the Manufacture of Enhanced Biomaterial Products

Duhduh A., Jaafar I.H., Coulter J.P., Lehigh University, US

A novel additive manufacturing technique, which we have coined as the “4D Rheoprinter”, has been developed. This technique enables 3D printing of polymers with tunable material properties for optimized performance in wide range of applications. [...]

Numerical and Experimental Investigation in Replicating a Micro-Featured Surface with the Injection Molding Process

Rajhi A., Jaafar I.H., Coulter J.P., Lehigh University, US

This paper describes current efforts to numerically and experimentally investigate micro and nanoscale features replication using the injection molding process. A silicon (Si) insert with micro–features is fabricated via photolithography followed by deep reactive ion [...]

An Integrated Biometric Platform for Evaluation of Targeted Drug Delivery

Liu Y., Thomas A., Uhl C., Wang S., He R., Lehigh University, US

In order to develop in vitro methods, which more closely resemble in vivo environments, a novel technology involving the use of microfluidic devices, which more closely mimic blood vessels has been developed. The technology has [...]

Transformative Design of Medical Oxygen Concentrator by Rapid Pressure Swing Adsorption

Vemula R.R., Kothare M.V., Sircar S., Lehigh University, US

The goal of this research work is design of a miniature medical oxygen concentrator (MOC) using a novel, single-bed rapid pressure swing adsorption (RPSA) process for personal use of chronic obstructive pulmonary disease (COPD) patients. [...]

Cell Detection and Discrimination by a Microfluidic-Integrated Broadband Microchamber

Denzi A., Apollonio F., Liberti M., Caterina M., Ning Y., Multari C., Palego C., Cheng X., Hwang J.C.M., Lehigh University, US

In the last years, the development of broadband microwave sensors for cell detection has become a great challenge. In this work, a broadband microchamber integrated with microfluidics is used for cell detection in the GHz [...]

A Five Input Majority Gate in Quantum-Dot Cellular Automatta

Akeela R., Wagh M.D., Lehigh University, US

We present a five input majority gate (MAJ5) designed in the quantum-dot cellular automata (QCA) technology. Unlike previous designs, our design is planer, uses integral cell placement and allows inputs and outputs from the peripheral [...]

A Fan-in Bounded Low Delay Adder for Nanotechnology

Sun Y., Wagh M.D., Lehigh University, US

This paper presents an adder designed specifically for nanoelectronics. It exploits the basic characteristics of nanoelectronic technologies such as the RTD, SET and QCA to provide an adder that has a very low delay and [...]

Implementation of Comparison Function Using Quantum-Dot Cellular Automata

Wagh M.D., Sun Y., Annampedu V., Lehigh University, US

Quantum-Dot cellular automata (QCA) architectures represent the future of computing. But it can only implement an inverter and a three input majority gate directly. Consequently very few QCA architectures are available in literature. By fixing [...]

The Influence of DNA Wrapping on SWNT Optical Absorption in Perpendicular Polarization

Snyder S.E., Rotkin S.V., Lehigh University, US

Single-walled carbon nanotubes (SWNTs) hold great promise for the next generation of electronic devices due to their small, biologically compatible size, exceptional electronic properties, and the range of bandgaps accessible with variations in diameter and [...]
