Evaporation from nanopores : probing interfacial transport
(Massachusetts Institute of Technology, 2018)
Evaporation, a commonly found phenomenon in nature, is widely used in thermal management, water purification, and steam generation as it takes advantage of the enthalpy of vaporization. Despite being extensively studied ...
Flapping wings for dual aerial and aquatic propulsion
(Massachusetts Institute of Technology, 2017)
Ocean sampling for short-transient underwater phenomena, such as harmful algal blooms, necessitates a vehicle capable of fast aerial travel interspersed with an aquatic means of acquiring in-situ measurements. Vehicle ...
Supernumerary robotic fingers for single-handed grasping and manipulation assistance
(Massachusetts Institute of Technology, 2017)
Hemiparetic patients, such as stroke survivors, have limited functionality in one of their hands and must constantly face challenges in completing simple bimanual tasks of daily living. A new type of wearable robot, namely ...
Studying phonon mean free paths at the nanoscale : modeling and experiments
(Massachusetts Institute of Technology, 2016)
Heat conduction in semiconductors and dielectrics involves cumulative contributions from phonons with different frequencies and mean free paths (MFPs). Knowing the phonon MFP distribution allows us to gain insight into the ...
Engineering light-matter interaction using two dimensional materials
(Massachusetts Institute of Technology, 2016)
The recent discovery of a new class of two dimensional(2D) atomic crystals allows the possibility of strong coupling of electromagnetic waves with various collective excitations such as plasmons and phonons, and carries ...
Analytical SLAM without linearization
(Massachusetts Institute of Technology, 2017)
This thesis solves the classical problem of simultaneous localization and mapping (SLAM) in a fashion which avoids linearized approximations altogether. Based on creating virtual synthetic measurements, the algorithm uses ...
Nonlinear acoustics in the presence of an object with sum or difference frequency sensing
(Massachusetts Institute of Technology, 2017)
A general and complete second-order theory of nonlinear acoustics in the presence of an object is derived and shown to be consistent with experimental measurements. The total second-order field occurs at sum or difference ...
Engineered microvasculature platforms to study tumor-host-matrix interactions during metastatic seeding
(Massachusetts Institute of Technology, 2017)
Distant metastases, which result in >90% of cancer related deaths, is enabled by hematogenous dissemination of tumor cells via the circulation. In particular, tumor cell extravasation is thought to be an essential and ...
Electrical impact assessment of dislocations in silicon materials for solar cells
(Massachusetts Institute of Technology, 2015)
Cast multicrystalline silicon (mc-Si) makes up about 60% of the global photovoltaics market production, and is favored due to its lower areal and capex costs relative to monocrystalline silicon. This method, however, ...
Development of bio-inspired distributed pressure sensor arrays for hydrodynamic sensing applications
(Massachusetts Institute of Technology, 2016)
The performance of marine vehicles is largely influenced by interactions with the flow around their hull, both self-generated and environmentally driven. To improve performance through flow control, a detailed, real-time ...
