Pumping liquids at small scales is challenging because of the principle of reversibility: in a viscous regime, the flow streamlines through a fixed geometry are the same regardless of flow direction. Recently we developed a class of microfluidic pump designs based on tilted flexible structures that combines the concepts of cilia (flexible elastic elements) and rectifiers (e.g., Tesla pump). We ...

An analysis to quantify the effects of packed bed channeling in the narrow passages of the ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Each CO2 adsorbent bed is paired with an upstream desiccant bed to condition the inlet air (i.e. remove water vapor) prior to entry ...

Mixing is an important process in a microfluidic system such as micro total analysis systems. In this paper, design and analysis of various micro-mixers for enhancing the mixing performance is presented. At first, the basic principles of mixing along with the mixing length and mixing time calculations are discussed. In general, macro-scale mixing is achieved with turbulence while mixing in micro ...

In this work, a piezoelectric tactile sensor will be designed and simulated using COMSOL Multiphysics®. The sensor is designed in order to assess the pressure exerted on the human body while the robotic surgery is performed. The sensor consists of a rigid and compliant cylindrical element. A circular PDMS (Polydimethylsiloxane) film is sandwiched between the rigid cylinder and the base plate to ...

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding with analytes in patient samples in order to generate a visual signal if disease-specific antigen is ...

Catalytic fast pyrolysis is a process by which biomass may be converted into liquid hydrocarbon transportation fuels and chemical co-products that are alternative to their petroleum-derived counterparts. Chemical compounds in raw pyrolysis vapor have high oxygen content and therefore must be deoxygenated in order to meet specifications for hydrocarbon fuels. One strategy to accomplish this is ...

Ocean is the cornerstone in Earth’s system because the surface of the Earth is covered by ocean about 71%. Ocean also holds approximate 97% of the Earth’s water. Ocean is always moving and continuous. This study is focusing on the ocean movement in Southern Ocean which is located in the southernmost of the Earth. It can be called as Antarctica Ocean because it consists of the waters extending ...

Abstract: A 3.2V/10Ah LFP aluminum-laminated batteries are chosen as the target of the present study. A three-dimensional thermal simulation model is established based on finite element theory and proceeding from the internal heat generation of the battery. The study illustrates a three-dimensional relationship among the total internal heat generation rate of the battery, the discharge rate ...

The novel concept of distributing the food super chilled (partially frozen) in order to prolong the shelf life has been suggested in the project. The temperature of the distribution chain is envisaged to be +5C. The suggested application has the following advantages: 1) Partial thawing of the product in the distribution chain makes it easier to handle. 2) The unhealthy and labour-demanding ...
