the separation of olefin/paraffin mixtures is an important process in petrochemical industries, which is traditionally performed by low temperature distillation with a high-energy consumption, or complex extractive distillationand adsorption techniques. membrane separation process is emerging as an alternative for traditional separation processes with respect to low energy and simple operation....

Tissue microarrays are becoming a very useful tool for research and immunohistochemistry and in situ hibridization quality control methods. We developed a new technique that allows to build high density paraffin blocks without using a recipient block for the tissue cores and without using a commercial TMA builder instrument. This technique is based on the construction of TMA needles modifying c...

Large and abrupt changes are observed at 38 degrees C in the 1100 cm(-1) region of the Raman spectrum of aqueous dipalmitoyl lecithin multilayers. They correspond to conformational changes due to the melting of the paraffin side chains. The addition of cholesterol to the multilayers broadens but does not abolish these changes. It is suggested that the addition of cholesterol decreases the inter...

This paper presents measurements of the thermal conductivity of paraffins mixtured with zeolites of the type 5A and 13X. Because of their high enthalpy change at the phase transition paraffins are able to store more thermal energy at nearly isothermal conditions than sensible heat materials. The poor thermal conductivity of paraffins is a disadvantage, however. The zeolite provides a structure ...

Growth rings were used to determine the root age of medicinal Paeonia lactiflora from four producing areas, and their corresponding paeoniflorin content were measured based on the identification of ages. Different P. lactiflora root samples of different ages were collected from the four major growing areas in China: Bozhou, Anhui Province; Pan'an, Zhejiang Province; Zhongjiang, Sichuan Province...

DURING the past year muchclinical observation has been' carried out in several. :Casualty Clearing Stations in this Army on the effect of liquid paraffin upon wounds at different stages. The results of these observations enable one to state: 1. That liquid paraffin has, almost without exception, a very beneficial action on the walls of a wound and on the tissues adjacent to the wound. It preven...

Superior encapsulation technology is important for PSCs to prolong their lifetime and realize commercial application. Paraffin/EVA/paraffin composite encapsulated layers were fabricated with the ambient environment under thermal temperature of 80°C, which has advantages simple procedures low cost. paraffin/EVA/paraffin pure EVA maintained 95 45% initial power conversion efficiency (PCE) aged 10...
