Abstract The measurement of static physico-chemical properties oil-water interfaces provides a useful method indicating where problem emulsion stability areas arise for water-in-crude oil emulsions and the effectiveness chemical demulsifiers in resolving these problems. paper includes discussion interfacial tension, shear viscosity film compressibility, particularly as applied to complex crude systems, deals with modification on addition demulsifier. Introduction Stable occur at many stages...
Abstract Purpose: Following cytotoxic therapy, 70% of patients with human papillomavirus (HPV)-positive oropharyngeal head and neck squamous cell carcinoma (HNSCC) are alive at 5 years compared 30% those similar HPV-negative cancer. Loss TGFβ signaling is a poorly studied consequence HPV that could contribute to patient outcome by compromising DNA repair. Experimental Design: Human HNSCC lines (n = 9), patient-derived xenografts tissue microarray 194), TCGA expression data 279), primary...
Deployable structures capable of significant geometric reconfigurations are ubiquitous in nature. While engineering contraptions typically comprise articulated rigid elements, soft that experience material growth for deployment mostly remain the handiwork biology, e.g., when winged insects deploy their wings during metamorphosis. Here we perform experiments and develop formal models to rationalize previously unexplored physics deployable using core-shell inflatables. We first derive a...
The interplay between thin film hydrodynamics and solidification produces formidably intricate geophysical structures, such as stalactites icicles, whose shape is a testimony of their long growth. In simpler settings, liquid films can also produce regular patterns. When coated on the underside flat plate, these are unstable yield lattices drops following Rayleigh-Taylor instability. While this interfacial instability well-studied in Newtonian fluids, much less known about what happens when...
We study the wrinkle patterns obtained when applying a thin polymeric film on uniaxially prestretched soft foundation. The is coated onto substrate where it drains under action of gravity, thereby introducing continuous variation in its thickness. first fluid mechanics component problem and derive coating profile as function curing properties solution. Upon polymerization, prestretch released yields formation wrinkles, which are arranged organized patterns, including fractals. variety...

From the pragmatic to symbolic, textiles play a prominent role in some of most demanding yet ubiquitous scenarios, such as covering complex and dynamic geometries human body. Textiles are made by repeated manipulations slender fibers into structures with emergent properties. Today, these ancient metamaterials being examined new light, propelled idea that their geometric can be leveraged engineer functional soft materials. However, per inherent softness, other compliant materials cannot...
Active systems of self-propelled agents, e.g., birds, fish, and bacteria, can organize their collective motion into myriad autonomous behaviors. Ubiquitous in nature across length scales, such phenomena are also amenable to artificial settings, where brainless robots orchestrate movements spatio-temportal patterns via the application external cues or when confined within flexible boundaries. Very much like natural counterparts, these approaches typically require many units initiate that...

Deployable structures, essential across various engineering applications ranging from umbrellas to satellites, are evolving include soft, morphable designs where geometry drives transformation. However, a major challenge for soft materials lies in achieving reliable actuation and stable shape retention their deployed state. Drawing inspiration biological growth processes, we demonstrate that irreversible plastic deformations can be leveraged create cellular metamaterials with permanent...
