Open AccessDirection-dependent dynamics of colloidal particle pairs and the Stokes-Einstein relation in quasi-two-dimensional fluids
Hydrodynamic interactions are important for diverse fluids, especially those with low Reynolds number such as microbial and particle-laden suspensions, and proteins diffusing in membranes. Unfortunately, while...

Relationships between structure, memory and flow in sheared disordered materials
A fundamental challenge regarding disordered solids is predicting macroscopic yield—the point at which elastic behaviour changes to plastic behaviour—from the microscopic arrangements of constituent particles....

Molecular heterogeneity drives reconfigurable nematic liquid crystal drops
With few exceptions1–3, polydispersity or molecular heterogeneity in matter tends to impede self-assembly and state transformation. For example, shape transformations of liquid droplets with monodisperse ingredie...

Open AccessDeposition and drying dynamics of liquid crystal droplets
Drop drying and deposition phenomena reveal a rich interplay of fundamental science and engineering, give rise to fascinating everyday effects (coffee rings), and influence technologies ranging from printing t...

Sodium bicarbonate causes dose-dependent increases in cerebral blood flow in infants and children with single-ventricle physiology
Sodium bicarbonate (NaHCO3) is a common treatment for metabolic acidemia; however, little definitive information exists regarding its treatment efficacy and cerebral hemodynamic effects. This pilot observational ...

Suppression of the coffee-ring effect by shape-dependent capillary interactions
When a drop of coffee dries, a halo of particles accumulates at the drop's edge. This 'coffee-ring effect', first described formally in a Nature paper in 1997, is a common occurrence when a solution of suspended ...

Diffuse Optical Measurement of Hemoglobin and Cerebral Blood Flow in Rat Brain During Hypercapnia, Hypoxia and Cardiac Arrest
Tissue viability and function are often manifest in hemodynamic signatures, because metabolism and vascular regulatory mechanisms modulate the concentration, oxygenation and flow characteristics of blood cells...

Entropic control of particle motion using passive surface microstructures
IN a colloidal suspension containing particles of two different sizes, there is an attractive force between the larger particles. This attraction is due to the extra volume that becomes available to the smalle...

Vibrational Dynamics of Condensed-Phase Molecules Studied by Ultrafast Infrared Spectroscopy
Infrared pump/probe measurements of T1 relaxation and oritentational relaxation of ions in hydrogen bonding solvents are discussed in terms of solvent induced enharmonic coupling.

Pulsed Diffusing-Wave Spectroscopy: Pathlength Specific Observation of Speckle Fluctuation Spectra from Dense Colloids
We introduce a probe of fluctuating dense random colloidal suspensions which uses phase fluctuations of optically gated photons to obtain pathlength specific speckle correlation functions.

Excitation of the 1S-2S Transition in Muonium
Muonium, the bound state of a positive muon and an electron, is one of the simplest systems for testing QED. Spectroscopic measurements in muonium are particularly attractive since the atom does not possess th...

Studies of Two-Level Atoms Identically Prepared by a Phase- and Amplitude-Controlled Excitation Field
While the response of two-level atoms to nearly resonant driving fields is in principle well known, experimental studies of such responses are generally limited to statistical systems where signals from atoms ...

Colliding Without Relaxing: The Suppression of Collisional Dephasing with Strong Optical Fields
Recently, considerable interest has arisen in the effect of relaxation on systems which are being strongly driven by a resonant electromagnetic field [1–6]. While this problem was originally encountered in stu...

Standing-Wave Induced Backward Photon Echoes in Gases
Recent interest in phase conjugation has made the process of degenerate-four-wave-mixing (D4WM) quite familiar.1 In standard D4WM experiments, a standing-and travelling-wave pulse are simultaneously applied to a ...
