Rapid prototyping bacterial spore hygro-actuators for soft robotics and adaptive materials

Cavusoglu A.‐H., Chen X., Tatem K., Sahin O., Columbia University, US

Over the past decade, rapid prototyping has migrated from the research and industrial labs into the homes of consumers. However, these solid models are limited in demonstrating dynamic actuation. A large range of soft materials [...]

Adsorption of Cd (II) Ions from Aqueous Solution Using Activated Carbon Prepared from Vitellaria paradoxa Shell

Adebayo G.B., Adekola F.A., Jimoh A.A., Alao F.O., Adegoke H.I., University of Ilorin, NG

Activated carbon prepared from vitellaria paradoxa shell using ortho-phosphoric acid as activating agent was used for the removal of Cd (II) ions from aqueous solution. The adsorbent sample was characterized by some physicochemical and spectroscopic [...]

Bioabsorbable Anti-inflammatory Material: A Novel Protein-Conjugated Polymer with Applications in the Implantable Medical Device Field

Rapier C.E., Chen E., Liu W.F., Lee A.P., University of California Irvine, US

Biodegradable/bioabsorbable materials are a relatively new movement in the implantable medical device field. Despite the promise of non-permanent implants, bioabsorbable materials can induce a localized inflammatory immune response. To overcome this limitation, we are combining [...]

Plasmonic Nanocages as Photothermal Transducers for Laser Induced Heating and Bubble Generation

Karampelas I.H., Alali F., Furlani E.P., SUNY-Buffalo, US

A series of new computational models is introduced to demonstrate several photonic and thermo-fluidic details of the photothermal process associated with nanosecond-pulsed, laser-heated gold nanocages. Such models can be used to simulate energy conversion within [...]

Guidelines for choosing an appropriate turbulence model when simulating blood flows in cardiovascular devices

Simpson B.A.F., Tansley G.D., Griffith University, AU

A systematic and detailed comparative study of computational results with validating experimental data has helped define the turbulence models that are most appropriate for predicting the velocity fields and shear forces in blood flows. The [...]

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 [...]

Low-cost spin-coatable, Transferable, and High-k Ion Gel Dielectric for Flexible Eletrowetting

Narasimhan V., Sanjairaj V., Park S.Y., National University of Singapore, SG

Electrowetting-on-dielectric (EWOD) is an emerging liquid-handling technology, enabling the wettability modulation of a liquid on a solid surface with an applied electric field. Recently, EWOD has been attractively used on flexible substrates to show potential [...]

Bottom-up Nanofabrication of Crystalline Structures of Magnetic Nanoparticles

Xue X., Furlani E.P., SUNY at Buffalo, US

A bottom-up approach to the nanofabrication of three-dimensional (3D) crystalline structures of magnetic core-shell nanoparticles is presented. The approach is based on self-assembly and involves the use of soft-magnetic template elements to guide the assembly [...]

Microfluidics for multiplexing of core needle biopsies

Mojica W.D., Oh K.W., Lee H., Xue X., Furlani E.P., University at Buffalo, US

Image guided biopsies for the procurement of diagnostic tissue has proven to be safe, cost effective and useful. However, the amount of tissue obtained is often diminutive and may be exhausted for conventional diagnostic purposes. [...]

On the dynamic contact angle in spontaneous capillary flow

Berthier J., Gosselin D., Delapierre G., CEA-LETI, FR

Capillary actuation of fluids is an interesting solution when the gravitational forces are small: this is the case in space , or in microfluidic systems where gravity is negligible. The onset of spontaneous capillary flow [...]
