Mechanical Mechanisms of Chemical Mechanical Polishing

Advanced Materials Research, 2008
This paper describes a mechanical mechanism of chemical mechanical polishing (CMP) and the model is applied to the polishing of silicon substrates by polyurethane pads and slurries containing fumed silica as is typically done in the manufacture of integrated circuits.

Mechanical mechanisms for thrombosis in microvessels

2007 IEEE 33rd Annual Northeast Bioengineering Conference, 2006
The hypothesis that thrombus can be induced in curved vessels due to mechanical stimuli was tested both experimentally and computationally. Our in vivo experiments on the mesentery of Sprague-Dawley rats (250-300 g) showed that thrombi were formed in non-injured curved microvessels (post-capillary venules, 20-50 micrometer in diameter), and they were ...

Models and Mechanisms of Stomatal Mechanics

Trends in Plant Science, 2018
The mechanism of stomatal function (control of gas flux through the plant surface via regulation of pore size) is fundamentally mechanical. The material properties of the pore-forming guard cells must play a key role in setting the dynamics and degree of stomatal opening/closure, but our understanding of the molecular players involved and resultant ...

The mechanism of mechanical alloying

Metallurgical transactions, 1974
The mechanical alloying process is a new method for producing composite metal powders with controlled microstructures. It is unique in that it is an entirely solid state process, permitting dispersion of insoluble phases such as refractory oxides and addition of reactive alloying elements such as aluminum and titanium.

Mechanisms and Mechanical Philosophy

2015
The past twenty years have seen a resurgence of philosophical interest in mechanisms, an interest that has been driven both by concerns with the logical empiricist tradition and by the sense that a philosophy of science that attends to mechanisms will be more successful than traditional alternatives in illuminating the actual content and practice of ...

Molecular mechanisms of cellular mechanics

Physical Chemistry Chemical Physics, 2006
Mechanical forces play an essential role in cellular processes as input, output, and signals. Various protein complexes in the cell are designed to handle, transform and use such forces. For instance, proteins of muscle and the extracellular matrix can withstand considerable stretching forces, hearing-related and mechanosensory proteins can transform ...

Mechanisms of Mechanical Alloying

1998
Unlike conventional processes in which materials are produced either by melting or sintering at high temperature, synthesis of different types of materials using the mechanical alloying or milling process is generally carried our at room temperature although temperature may rise during milling.

Mechanics without mechanisms

Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 2018
Abstract At the time of Heinrich Hertz's premature death in 1894, he was regarded as one of the leading scientists of his generation. However, the posthumous publication of his treatise in the foundations of physics, Principles of Mechanics, presents a curious historical situation. Although Hertz's book was widely praised and admired, it was also met

Mechanisms of hypoxemia

Intensive Care Medicine, 2005
A fundamental aspect of cardiopulmonary homeostasis is the adequate delivery of oxygen to meet the metabolic demands of the body. Cardiac output, O2-carrying capacity (i.e., hemoglobin concentration and quality), and arterial PO2 (PaO2) determine O2 transport.
