Mechanochemical Phenomena in Pulverizing Operation

Pulverizing Air Dryer

Finite element implementation of mechanochemical phenomena in neutral deformable porous media under finite deformation.

Biological soft tissues and cells may be subjected to mechanical as well as chemical (osmotic) loading under their natural physiological environment or various experimental conditions. The interaction of mechanical and chemical effects may be very significant under some of these conditions, yet the highly nonlinear nature of the set of governing equations describing these mechanisms poses a cha...

Cancer Genomes Evolve by Pulverizing Single Chromosomes

A report in this issue describes "chromothripsis," a new mechanism for genetic instability in cancer cells. Chromothripsis appears to be a cataclysmic event in which a single chromosome is fragmented and then reassembled. The phenomenon raises important questions of how chromosome rearrangements can be confined to defined genome segments.

Mechanochemical Coupling in Flagella

The relation between oxygen consumption and motility of Ciona spermatozoa has been measured by using pH stats to measure the acid production of spermatozoa swimming in dilute suspensions where their motility can be analyzed accurately, and calibrating the acid production by measuring it simultaneously with measurements of oxygen consumption, using more concentrated sperm suspensions. When the m...

Nanoscale Studies on Aggregation Phenomena in Nanofluids

Understanding the microscopic dispersion and aggregation of nanoparticles at nanoscale media has become an important challenge during the last decades. Nanoscale modeling techniques are the important tools to tackle many of the complex problems faced by engineers and scientists. Making progress in the investigations at nanoscale whether experimentally or computationally has helped understand th...
