The nanostructure of a peptide amphiphile in commercial use in anti-wrinkle creams is investigated. The peptide contains a matrikine, collagen-stimulating, pentapeptide sequence. Self-assembly into giant nanotapes is observed and the internal structure was found to comprise bilayers parallel to the flat tape surfaces.

Wrinkle ridges are the largest and most morphologically complex contractional landforms found on Moon. They occur exclusively in mare basalt thought to result from load induced subsidence flexure of lunar lithosphere. The displacement-length (Dmax/L) relations wrinkle ridge thrust faults mascons, where basalts generally thickest, non-mascon settings compared. results show no statistically signi...

The processing of thin-structured materials in a fluidic environment, from nearly inextensible but flexible graphene sheets to highly extensible polymer films, arises many applications. So far, little is known about the dynamics such thin freely suspended fluid. In this work, we study soft uniaxial extensional flow. Elastic are modeled with continuum model that accounts for in-plane deformation...

It is generally recognized that Caucasians and Asians have different skin aging features. The aim of this study was to develop a facial wrinkle grading scale for Chinese women. Standard photographs were taken of 242 Chinese women. Six sets of 0 to 9 wrinkle scales with reference photographs and descriptions were selected, including grading scales for resting and hyperkinetic crow's feet, fronta...

BACKGROUND AND OBJECTIVE Ablative fractional lasers were introduced for treating facial rhytides in an attempt to achieve results comparable to traditional ablative resurfacing but with fewer side effects. However, there is conflicting evidence on how well this goal has generally been achieved as well as on the comparative value of fractional CO(2) and Er:YAG lasers. The present study compares ...

We present a general analytical model for determining the location and pattern of wrinkles in thin membranes and for making preliminary estimates of their wavelength and amplitude. A rectangular membrane under simple shear and a square membrane subject to corner loads are analysed. In the first problem, our model predicts the wavelength and the wrinkle amplitude to be respectively inversely pro...
