Investigation of Ion Facilitation Using Corrugated Membrane in Electrodialysis

Priyabrata Mandal [1], Priya Goel [1], Anusha Chandra [1], Dr. Sujay Chattopadhyay [1]
[1] Indian Institutes of Technology Roorkee Saharanpur Campus, Saharanpur, Uttar Pradesh, India

Electrodialysis(ED) is an electrochemical separation process in which charged membranes are used to separate ionic species in presence of electrical potential. The efficiency of ED depends on polar membranes, flow hydrodynamics of electrolytes, concentration polarization arising due to ... Read More

MEMS Based Mass Sensor with Uniform Sensitivity for Biological Applications

Aditya Algn [1], Dr. Elizabeth Rufus [1],
[1] VIT Vellore, Vellore, Tamlinadu, India

MEMS sensors exhibit rapid response with minimum sample volume at higher sensitivities. This makes them suitable for detection of Micro/nanoparticles and can also use to monitor their physical process at that scales. Micro-cantilevers based sensing is widely used in the detection of mass ... Read More

Investigation on Quiet Zones Created by Remote Impedance Control

T. Laurence [1], R. Boulandet [1], H. Lissek [1],
[1] LTS2 - Acoustics Group, EPFL, Switzerland

Quiet zones and other sound zones have been a strong topic of research for some time, due to the interest of creating separate sound environments in a same room, in a large open-space office for example. A number of solutions have been proposed over the last years. This paper further ... Read More

Simulating Approaches for Heating Process in Continuous Furnaces

G. Petrone [1], R. Sinatra [1], C. Barbagallo [1],
[1] BE CAE & Test, Italy

Heating of pieces evolving in tunnel furnaces is an argument of high interest in several industrial processes such as thermal treatment of metals, glass production and food industry.Because of pieces move into the furnace, heat flux they receive from fixed heat sources is variable in ... Read More

Simulating Survival and Insulin Secretion in Pancreatic Islet Tissue Constructs

E. Han [1], L. E. Niklason [1],
[1] Department of Biomedical Engineering, Yale University, New Haven, CT, USA

Type I diabetes results from the autoimmune destruction of pancreatic islets and is a growing and cost intensive chronic health problem throughout the world. Monitoring blood sugar levels and recurrent intervention with exogenous insulin allows many patients to lead relatively normal ... Read More

Numerical Study of Membrane Polarization for a Network of Connected Pores

N. Rezaii [1], A. Hördt [1],
[1] Braunschweig University of Technology, Institute for Geophysics and Extraterrestrial Physics, Braunschweig, Germany

Spectral Induced Polarization (SIP) is a geophysical technique that measures the frequency dependence of the electrical conductivity of a material. The potential of using SIP to predict the hydraulic conductivity of the ground has been investigated since 1950s. However, the dependency of ... Read More

Knowledge and Skills Acquisition via a “Parallel” Problem Solving Approach

J. R. Sanders [1], S. N. Jorgensen [1],
[1] Tennessee Technological University, Cookeville, TN, USA

To be competitive in today’s workforce, students in STEM undergraduate programs are expected to develop problem-solving skills. Often, this occurs through guidance and practice in the form of assignments, labs, experiential learning opportunities, teamwork, and other means. The concept ... Read More
