Mechanisms of reorientation in phytoplankton : fluid shear, surface interactions, and gravitaxis
(Massachusetts Institute of Technology, 2014)
Phytoplankton are a vital part of the ecosystem in oceans and lakes, where they form the base of the food chain and have major global impacts, for example producing 50% of the planet's oxygen. Phytoplankton can also serve ...
Predictive design and fabrication of complex micro and nano patterns via wrinkling for scalable and affordable manufacturing
(Massachusetts Institute of Technology, 2014)
There is a demonstrated need for scalable and affordable manufacturing of complex micro and nano scale structures for applications such as fluidics-based medical diagnostics and photonicsbased sensing. Although high-rate ...
The design and manufacture of immediate-release optimal solid dosage forms
(Massachusetts Institute of Technology, 2014)
Pharmaceutical manufacturing has traditionally been considered largely a matter of regulatory compliance. Consequently, it has been inefficient, but it is now increasingly being recognized as an opportunity for cost ...
A novel means of cardiac catheter guidance for ablation therapy of ventricular tachycardia
(Massachusetts Institute of Technology, 2014)
This work presents a system for identifying the site of origin of ventricular tachycardia (VT) and guiding a catheter to that site in order to deliver radio-frequency (RF) ablation therapy. Myocardial infarction (MI), also ...
Elongated fascicle-inspired 3D tissues consisting of high-density, aligned, optogenetically excitable muscle tissue using sacrificial outer molding
(Massachusetts Institute of Technology, 2014)
The majority of muscles, nerves, and tendons are composed of fiber-like fascicle morphology. Each fascicle has a) elongated cells highly aligned with the length of the construct, b) a high volumetric cell density, and c) ...
The linear and nonlinear rheology of multiscale complex fluids
(Massachusetts Institute of Technology, 2014)
The microstructures of many complex fluids are typically characterized by a broad distribution of internal length scales. Examples of such multiscale materials include physically and chemically cross-linked gels, emulsions, ...
A deviational Monte Carlo formulation of ab initio phonon transport and its application to the study of kinetic effects in graphene ribbons
(Massachusetts Institute of Technology, 2014)
We present a deviational Monte Carlo method for solving the Boltzmann equation for phonon transport subject to the linearized ab initio 3-phonon scattering operator. Phonon dispersion relations and transition rates are ...
Development of a miniature, continuous measurement, stochastic perturbation gas chromatograph
(Massachusetts Institute of Technology, 2014)
Gas chromatography is one of the most widely used analytical chemistry techniques for separating and analyzing chemical compounds. Chromatographic methods are used to identify constituent species within a compound and ...
Multifocal Multiphoton Microscopy for Neurobiological Imaging
(Massachusetts Institute of Technology, 2014)
Observing neuronal structures and monitoring changes in synaptic connectivity with respect to time have a significant impact on understanding the basis of structural brain abnormalities and the development of therapeutics ...
Needle-free interstitial fluid acquisition using a Lorentz-force actuated jet injector
(Massachusetts Institute of Technology, 2014)
Interstitial fluid (ISF) provides information on a patient's health as it contains regulatory molecules that are correlated with disease-related processes. However, current ISF acquisition techniques can be slow, resulting ...
