Paramagnetic Colloids in Rotating Fields: From Chains through Chaos to Clusters

We present computer simulations and experiments on dilute suspensions of superparamagnetic particles subject to rotating magnetic fields.  We focus on short chains of particles and their decay routes to stable structures.  At low rate, the chains track the external field.  At intermediate rate, the short chains break up, but perform a periodic (albeit complex) motion. … See More

Brain-Computer Interface using EEG signals

There are currently various forms of interactions with machines and robots that simplify the interface between the system and the user. We are currently looking for a method to directly control electronic systems using our brain waves as a means of communicating with said systems. Electroencephalography (EEG) has attracted the eye of thousands of researchers and … See More

Physiological Closed-Loop Control For Smart Medical Systems

Recent advances in medical sensing devices have enabled the accurate measurement of physiological signals; however, the long-standing patient-clinician-device paradigm still remains largely unaffected and/or in its infancy stage. The cause for this is quite simple; that is, most modern medical devices are not capable of performing self-regulation of applied therapeutic actions. By designing self-regulating, self-adapted … See More

Magnesium Oxide Nanoparticles as a Regenerative CO2 Sorbent

Metal Organic Frameworks (MOFs), constructed by the assembly of metal-containing units with appropriate organic linking groups, are a class of crystalline porous materials.  In recent years, MOFs have captured widespread research interest due to their intriguing structural topologies and potential applications as functional materials in wide fields such as gas storage, separation, catalysis, drug delivery, … See More

Use of Ozone to Remove Soluble Organic Nitrogen and Soluble Organic Phosphorus from Wastewater

Nutrient pollution in surface waters can lead to eutrophication. Since a significant source of nutrients in water comes from wastewater discharges, increasingly stringent limits have been imposed on wastewater treatment plants. To meet these limits, higher-level treatments are needed to remove soluble organic nitrogen (SON) and soluble organic phosphorus (SOP) compounds which are resistant to … See More

Endothelial Glycocalyx Conditions affect Cellular Uptake of Gold Nanoparticles

Cardiovascular diseases are facilitated by endothelial cell (EC) dysfunction and coincide with EC glycocalyx coat shedding. These diseases may be deterred by targeting medications to affected vascular regions using circulating nanoparticle drug carriers.  The objective of the present study was to observe how EC-targeted delivery of 10nm polyethylene glycol-coated gold nanoparticles (PEG-AuNP).  Rat fat pad … See More

A 10-Gb/s Serial-Link Receiver Design for USB 3.1 with a Continuous-Time Linear Equalizer and 1-Tap DFE

This paper presents a wire-line receiver design of CMOS I/O at 10-Gb/s data rate for USB 3.1 standard. A power efficient continuous time linear equalizer (CTLE) and 1-tap look-ahead decision feedback equalizer (DFE) are designed and implemented in a 45nm CMOS technology. The DFE employs a sampler including a current injection section that makes no use of summer as a separated … See More

Aminopolymer Impregnated MCM-36 and the Effect of Pore Structure on CO2 Capture

Porous solid adsorbents are currently being studied for their potential use as an effective way to capture carbon dioxide. These absorbents are known to have high surface areas and low heats of adsorption, making them ideal for capturing carbon dioxide. The perfect adsorbent would possess high amine loading abilities and high adsorption capacity. A 2-dimensional … See More

Developing Plant Tissue Cultures for the Production of Pharmaceuticals

As long as humans have been getting ill, they have been using plants as medicine. Today, plants can be used as production platforms for a range of pharmaceuticals. The plant Catharanthus roseus, or the Madagascar periwinkle, produces the anti-cancer drugs vincristine and vinblastine which cost from $4 – $20 million dollars per kilogram. The overall … See More

Low-Cost Robotic Actuator

Many mobile robots require compact drive systems (actuator/transmission/joint) that deliver high torques through stiff mechanical ports. Conventional drive systems are made from off-the-shelf actuators and transmissions, which are coupled together to power the robot’s joints. This approach has several benefits such as short development time because of the available mechanical components, however, lacks a system-level … See More
