It won the Best New Journal 2011 award from the Association of Learned an... | https://en.wikipedia.org/wiki?curid=30929442 |
Anthraquinone process The anthraquinone process is a process for the production of hydrogen peroxide, which was developed by BASF. The industrial production of hydrogen peroxide is based on the reduction of oxygen, as in the direct synthesis from the elements. Instead of hydrogen itself, however, a 2-alkyl-anthrahydroq... | https://en.wikipedia.org/wiki?curid=30932321 |

Short-path distillation is a distillation technique that involves the distillate travelling a short distance, often only a few centimeters, and is normally done at reduced pressure. A classic example would be a distillation involving the distillate travelling from one glass bulb to another, without the need for a conde... | https://en.wikipedia.org/wiki?curid=30942109 |
Thermoporometry and cryoporometry are methods for measuring porosity and pore-size distributions. A small region of solid melts at a lower temperature than the bulk solid, as given by the Gibbs–Thomson equation. Thus, if a liquid is imbibed into a porous material, and then frozen, the melting temperature will provide i... | https://en.wikipedia.org/wiki?curid=30950746 |
Thermoporometry and cryoporometry They are both particular cases of the Gibbs Equations (Josiah Willard Gibbs): the Kelvin equation is the constant temperature case, and the Gibbs–Thomson equation is the constant pressure case. This technique uses differential scanning calorimetry (DSC) to detect the phase changes. The... | https://en.wikipedia.org/wiki?curid=30950746 |
Thermoporometry and cryoporometry To make the measurement it is common to just measure the amplitude of an NMR echo at a few milliseconds delay, to ensure that all the signal from the solid has decayed. The technique was developed at the University of Kent in the UK, by Prof. John H. Strange. NMRC is based on two equat... | https://en.wikipedia.org/wiki?curid=30950746 |
Thermoporometry and cryoporometry Similarly the freezing and melting curvatures (typically spherical on ice intrusion, and cylindrical on ice melting), result in a difference in freezing and melting temperature even in cylindrical pores where there is no "ink-bottle" effect. It is also possible to adapt the basic NMRC ... | https://en.wikipedia.org/wiki?curid=30950746 |
