High resolution nanoparticle size determination by vapor condensation and the verification of classical heterogeneous nucleation theory
Published: September 30, 2022

Abstract: The phenomenon of heterogeneous nucleation in the gas phase is briefly introduced, as well as a related instruments referred to as a condensation particle counter (CPCs). CPCs are widely used to detect single nanometer particles and molecular ions, by growing them into visible sizes. We review prior use of sheathed CPCs, where nanoparticles are […]

Functionality through multistability: from soft robots to deployable structures
Published: September 30, 2022

Abstract: Inflating a rubber balloon leads to a dramatic shape change: a property that is exploited in the design of soft robots and deployable structures. On the one hand, fluid-driven actuators capable of complex motion can power highly adaptive and inherently safe soft robots. On the other hand, inflation can be used to transform seemingly […]

Growth and morphogenesis of confined bodies
Published: September 14, 2022

Abstract: Natural phenomena, such as growth, instability, and failure, can be highly dependent upon activation of stochastic mechanisms at the microscale, such as the existence of microscopic imperfections, the action of molecular motors, and the diffusion of constituents. Yet, at the macroscale, astonishing order is often observed. In this talk, I will discuss our recent […]

Dynamics of Flow Past Shark-Inspired Textured Surfaces
Published: September 14, 2022

Abstract: Skin of fast swimming shark species such as Mako are packed with overlapping micro-scale denticles where each denticle is covered with 3-7 ribs. These textures allow sharks to swim faster than other animals in the ocean. Inspired by this capability, two-dimensional symmetric and periodic textures have been considered for the purpose of drag control […]

Wave propagation in meta-structures: beyond conventional limitations
Published: April 11, 2022

http://s.uconn.edu/meseminar4.22.22 Abstract: Meta-structures are artificially engineered structures designed to exhibit properties not found in conventional materials. By careful design, one can obtain unprecedented control over various physical properties. Examples in mechanics includes structures having unique static and dynamic properties like negative Poisson’s ratio, zero shear modulus and non-reciprocal wave propagation.  Waveguides transporting energy and information […]

Tissue engineering with soft matter
Published: February 22, 2022

http://s.uconn.edu/meseminar3/11/22 Abstract: The extracellular matrix (ECM) guides cells through mechanical and soluble signals among others. We guide cell behaviors using these two aspects of ECM.  Even the bone ECM is soft after de-mineralization. Thus, we are interested in soft polymeric materials. Many tissues in our body are elastic including blood vessels, our target tissue. We […]

On the stability and structure of turbulent premixed bluff-body stabilized flames at elevated pressure
Published: February 21, 2022

http://s.uconn.edu/meseminar2/25/22 Abstract: Energy conversion and propulsion systems operating with a lean, premixed mode of combustion are advantageous in terms of both emissions and economics. This is because fully premixing fuel and oxidizer prior to combustion can reduce harmful exhaust levels, while operating fuel lean ensures complete fuel consumption, providing superior fuel economy. In fact, it […]

The mechanical behaviors of bone across multiple length scales
Published: January 18, 2022

http://s.uconn.edu/meseminar1/28/22 Abstract: Bone is strong, tough yet lightweight, which can be attributed to its complex hierarchical structures across multiple length scales. The factors contributing to these superior properties are still not completely understood, especially its structure at the sub-micron- and nano-scales. The morphology and mechanical properties of bone are also affected by diseases and treatment. This […]
