Negative Heat Capacity for a Cluster of 147 Sodium Atoms
... energy can be added to a star or star cluster which then cools down. A similar effect has been calculated for melting atomic clusters [3,4] and fragmenting nuclei [5]; in the latter case it has been observed as well [6]. We have recently developed a method to study thermal properties of free, mass s ...

Chapter 7 Neutron Stars - Ira-Inaf
... gravitational potential energy of an electron at the surface of such a star would be less than 0.1% its rest mass energy. This tells us that general relativistic effects are not important to white dwarf physics. 7.2 Neutron stars The above discussion points out the the final state of a star that has ...

Elasticity and Fluid Physics
... Bose-Einstein Condensates, also known as BEC’s, are clusters of millions of atoms that merge under conditions of extreme cold. BEC’s can form in some gases when they are cooled to within a few billionth of a Celsius degree of absolute zero. When a BEC forms, million of atoms stop moving in differe ...

pH meters and their electrodes: calibration, maintenance and use
... The glass electrode can be used with strong acids; however, it is attacked by strong alkaline solutions. Therefore, glass electrodes should never be left in alkaline solutions for longer than is necessary to measure the pH. The glass electrode responds rapidly to large pH changes in buffered solutio ...

Microplasma
Microplasmas are plasmas of small dimensions, ranging from tens to thousands of micrometers. They can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.
