The Mechanical Properties of the Cell Surface
نویسندگان
چکیده
In the first paper of this series (Mitchison & Swann, 1954), we have discussed the problems of measuring the mechanical properties of the cell membrane and described both the construction and use of the 'cell elastimeter', and the method of analysing the results by means of model experiments. The present paper is concerned with measurements made on the unfertilized eggs of five species of sea urchin, with the object of determining Young's modulus for the membrane and the internal pressure of the cell. Future papers will describe the changes in the membrane of the fertilized egg up to the time of cleavage, and the influence of chemical agents and electric currents on the membrane of the unfertilized egg.

Influence of Different Foaming Conditions on the Mechanical, Physical, and Structural Properties of Polypropylene Foam
In this article, the effects of different foam production times and temperatures on the mechanical, physical, and structural properties of polypropylene (PP) foam has been investigated. The microcellular PP foams were carried out using supercritical carbon dioxide (sc-CO2) as a physical foaming agent in a batch process. The samples were placed in a pressure vessel and were saturated ...
متن کاملThe Impact of Wettability on Effective Properties of Cathode Catalyst Layer in a Proton Exchange Membrane Fuel Cell
The produced liquid water in cathode catalyst layer (CCL) has significant effect on the operation of proton exchange membrane fuel cell (PEMFC). To investigate this effect, the transport of oxygen in CCL in the presence of immiscible liquid water is studied applying a two-dimensional pore scale model. The CCL was reconstructed as an agglomerated system. To explore the wettability effects, diffe...
متن کاملCure Characteristics and Physico-mechanical Properties of the Stearic Acid Surface of Modified Calcium Carbonate Reinforcement NR/SBR Compounds
Calcium carbonate is a cheap and readily available filler used in rubber industry. This material is not compatible with rubber matrix, so many researchers have tried to modify its surface with various materials in order to increase its hydrophobicity and improve compatibility with the rubber matrix. In this effort, surface modification of calcium carbonate was carried out by 1.5%, 3% and 4% ste...
متن کاملEvaluating the effect of pH on mechanical strength and cell compatibility of nanostructured collagen hydrogel by the plastic compression method
Objective(s): One of the main constraints of collagen hydrogel scaffolds for using in tissue engineering is mechanical weakness. Plastic compression (PC) is a physical method to overcome the mechanical limitation of collagen hydrogel. Materials and Methods: In this study, the effects of pH on mechanical and biological properties of PC hydrogels were investigated. Collagen hydrogels were fabrica...
متن کاملThe effect of increasing the multiplicity of flow fields contact surface on the performance of PEM fuel cell
In this paper, three innovative 3-D geometries for flow fields of cathode and anode have been developed to investigate the comparative impact of increasing the multiplicity of the involved anode-cathode channel surface contact on the efficiency of electrochemical reaction via the same membrane electrode assembly (MEA) active area. In the introduced new models, each anode channel includes two, t...

Coating plays a significant role in surface engineering, which leads to the improvement of the mechanical and metallurgical properties of products. It also brings about economic benefits thanks to the cost savings of the improved properties of the surface of a product in particular. Friction surfacing is a relatively new way to create a homogeneous, fine-grained coating with amended resistance ...
