A homogenization result is given for a material having brittle inclusions arranged in a periodic structure. According to the relation between the softness parameter and the size of the microstructure, three different limit models are deduced via Γ-convergence. In particular, damage is obtained as limit of periodically distributed microfractures.

The size-dependence of different local reactivity descriptors of dimer A2 and AB type of systems is discussed. We derive analytic results of these descriptors calculated using finite difference approximation. In particular, we studied Fukui functions, relative electrophilicity and relative nucleophilicity, local softness and local philicity. The results are explained using the example of the di...

We present a new experimental system (the “atom-optics billiard”) and demonstrate chaotic and regular dynamics of cold, optically trapped atoms. We show that the softness of the walls and additional optical potentials can be used to manipulate the structure of phase space.

A homogenization result is given for a material having soft inclusions arranged in a periodic structure, under the requirement that the interpenetration of matter is forbidden. According to the relation between the softness parameter and the size of the microstucture, three different limit models are deduced via Γ-convergence.

Introduction: One of the limitations of tissue conditioners (TC) is gradual hardening of the material in a short time period after insertion in the mouth, due to the loss of their viscoelastic properties. The aim of this study was to determine the softness of two different tissue conditioners with and without the Monopoly

To provide realistic tactile sensations in a virtual environment, it is necessary to stimulate both the cutaneous and proprioceptive senses. This study focuses on method of presenting softness through use electro-tactile stimulation. Our system combines force-feedback device with an electric stimulator create soft sensation by applying reaction force spreading based amount indentation. We measu...

Fat hardness/softness directly affects efficiency of processing and fat also contributes to the desirable eating attributes of meat. In terms of meat quality, fat quality attributes of colour, hardness and texture are important for certain markets. The quality of fat can markedly affect the carcase value at the wholesale level—particularly that for the Japanese market, which prefers soft white ...

A resorufin–dinitrophenyl ether conjugate (1) shows emission enhancement for aromatic thiols in aqueous media with a neutral–basic pH, while being nonemissive for aliphatic thiols. This is achieved by two electrophilic sites with different local softness on compound 1; the respective sites selectively react with aromatic or aliphatic thiolate anions.

Correction for 'Towards the rationalization of catalytic activity values by means of local hyper-softness on the catalytic site: a criticism about the use of net electric charges' by Jorge Ignacio Martínez-Araya et al., Phys. Chem. Chem. Phys., 2015, DOI: 10.1039/c5cp03822g.

This study aims to understand the effect of micro- and nanofibrillated cellulose (MNFC) on tensile index, softness, water absorbency tissue paper. MNFC was produced from four different fiber sources. The results show that acts as an effective strength enhancer at expense a reduced softness. impact source manufacturing cost trade-off with performance also investigated. MNFCs southern bleached ha...
