Biomimicry (bio- meaning life in Greek, and -mimesis, meaning to copy) is a growing field that seeks to interpolate natural biological mechanisms and structures into a wide range of applications. The rise of interest in biomimicry in recent years has provided a fertile ground for innovation. This review provides an eco-system based analysis of biomimicry inspired technology and product innovation. A multi-disciplinary framework has been developed to accomplish this analysis and the findings focus on the areas that have been most strikingly affected by the application of biomimicry and also highlight the emerging trends and opportunity areas. © 2014 Elsevier Inc.

Gut microbes | Year: 2013
Certain randomized, placebo-controlled trials of oral supplementation with B. infantis 35624 have demonstrated the amelioration of symptoms of irritable bowel syndrome. Potential GI colonization by B. infantis 35624 or effects of supplementation on resident GI microbiota may pertain to these clinical observations. In this study, fecal excretion of B. infantis 35624 before, during and after 8 weeks of daily treatment was compared in subjects with IBS who received either the encapsulated oral supplement (n = 39) or placebo (n = 37) and in healthy subjects who received the supplement (n = 41). Secondarily, changes in assessed fecal microbiota and IBS symptoms were determined. Supplementation significantly increased fecal B. infantis 35624 excretion vs. placebo in IBS subjects; excretion in healthy subjects receiving supplement was quantitatively similar. Fecal levels of the probiotic declined and approached baseline once dosing ceased, documenting that colonization is transient. Although supplementation increased numbers of B infantis 35624 within the GI tract, limited changes in 10 other fecal taxa were observed either in healthy subjects or those with IBS. No impact on IBS symptoms was observed. Detection of bacterial DNA in fecal samples suggests that the probiotic is able to survive transit through the GI tract, although strain selective culture techniques were not performed to confirm viability of B. infantis 35624 in the feces. Continuous probiotic administration was necessary to maintain steady-state transit. Given the complex spectrum of GI microbiota, however, monitoring perturbations in selected taxa may not be not a useful indicator of probiotic function.

Vibrational Spectroscopy | Year: 2012
Inner working mechanisms of two-dimensional (2D) correlation spectroscopy, including sometimes overlooked but important details, were reviewed to clarify how and why this technique works for a broad range of applications. The role of external perturbation in 2D correlation spectroscopy and the importance of clearly defining the observation interval of data collection are discussed. The underlying concept of synchronicity based on phase relationship is described for simple sinusoidal signals and for generalized waveforms without heavily relying on mathematical formalism. The effect of band frequency shift on 2D correlation spectra turned out to be less significant than previously believed for most experimental data. Careful examination of the soundness of the theoretical ground confirms that 2D correlation spectroscopy is a robust and useful technique broadly applicable to the analysis of spectral data. Thorough understanding of the background makes it possible to further expand of this versatile technique toward various new applications, such as projection 2D correlation spectroscopy. © 2012 Elsevier B.V.

Vesicles are hollow aggregates, composed of bilayers of amphiphilic molecules, dispersed into and filled with a liquid solvent. These aggregates can be formed either as equilibrium or as out of equilibrium meta-stable structures and they exhibit a rich variety of different morphologies. The surprising richness of structures, the vast range of industrial applications and the presence of vesicles in a number of biological systems have attracted the interest of numerous researchers and scientists. In this article, we review both the thermodynamics and the kinetics aspects of the phenomena of formation of vesicles. We start presenting the thermodynamics of bilayer membranes formation and deformation, with the aim of deriving the conditions for the existence of equilibrium vesicles. Specifically, we use the results from continuum thermodynamics to discuss the possibility of formation of stable equilibrium vesicles, from both mixed amphiphiles and single component systems. We also link the bilayer membrane properties to the molecular structure of the starting amphiphiles. In the second part of this article, we focus on the dynamics and kinetics of vesiculation. We review the process of vesicles formation both from planar lamellar phase under shear and from isotropic micelles. In order to clarify the physical mechanisms of vesicles formation, we continuously draw a parallel between emulsification and vesiculation processes. Specifically, we compare the experimental results, the driving forces and the relative scaling laws identified for the two processes. Describing the dynamics of vesicles formation, we also discuss why non equilibrium vesicles can be formed by kinetics control and why they are meta-stable. Understanding how to control the properties, the stability and the formation process of vesicles is of fundamental importance for a vast number of industrial applications. © 2009 Published by Elsevier B.V.

This paper describes some data analyses for the TDS data used in the workshop at the 2014 Sensometrics meeting, employing flavored fresh cheese. An initial statistical significance test for the data of both the panel and the consumers shows that the consumer data is much richer in terms of discriminating between the products. This might be attributed to the lower sample size for the trained panel, but even increasing the significance level to 20% (rather than 5% as for the consumer data) did not give similarly rich information. The panel primarily discriminated the products on a single attribute. Adding the temporal hedonic data to the difference TDS curves between products suggests that absence of cooked herbs and the presence of fresh herbs seem to be main drivers of liking. For an alternative approach, the data was split into 4 time periods, and considered as check-all-that-apply (CATA) per period. The resulting Penalty-lift analysis supports the above findings and indicates that garlic and salty are the next most important positive, with pepper being another negative driver of liking. The respective correspondence analysis (CA) shows a clear separation between the products. Results suggest that it might be worth exploring repeated CATA as an alternative to TDS, offering the possibility to check more than just one attribute at a time. Finally, consumer (temporal) liking was added to the CA in a biplot way, showing substantial heterogeneity among the assessors. © 2015 Elsevier Ltd.
