The need to increase the productivity and capacity of power transformers has conditioned production insulating papers a higher thermal class. For this purpose, various techniques solid insulation modification were applied, which enable in chemical stability paper during operation transformer. applied additives, primarily dicyandiamide (DICY) polyacrylamide (PAM), are one form cellulose final st...

During a haemodialysis (HD), because of the contact of blood with the surface of the dialyser, the immune system becomes activated and reactive oxygen species (ROS) are released into plasma. Particularly exposed to the ROS are lipids and proteins contained in plasma, which undergo peroxidation. The main breakdown product of oxidized lipids is the malondialdehyde (MDA). A common method for measu...

Understanding the interactions of humid air with ionic liquids (ILs) is critical for predicting how their physicochemical properties are affected by water. Using experimental and theoretical techniques, water vapor's interaction with aerosolized nanoparticles and thin films of [C(2)MIM][Cl] and [C(2)MIM][BF(4)] was studied. Solutions were electrosprayed to produce dry particles. Particles' hygr...

Surgical management of ovarian tumours largely depends on their histo-pathological diagnosis. Currently, screening for ovarian malignancy with tumour markers in conjunction with radiological investigations has a low specificity for discriminating benign from malignant tumours. Also, pre-operative biopsy of ovarian masses increases the risk of intra-peritoneal dissemination of malignancy. Intra-...

tissue engineering is defined as the designing and engineering of structures to rebuild and repair a body damaged tissue. scaffolding poly hydroxy butyrate valraty (phbv) has shown good biocompatibility and biodegradable properties. nanofibers have improved the performance of biomaterials, and could be considered effective. one of the important methods for designing nanofiber scaffold is the el...

ATR-FTIR (Attenuated Total Reflectance Fourier Transform Infrared) spectra of prehardened epoxies with varying amounts of hardener and resin (mix ratio) have been acquired on a Midac FTIR spectrometer. The spectra form a set of training spectra for partial least-squares (PLS) analysis which was then used to analyze a series of epoxies of unknown mix ratio. The PLS model predicted the unknown mi...

We report a family of biocompatible ionic liquids (ILs) which are able to dissolve significant amounts of proteins such as cytochrome c and in which ATR-FTIR spectroscopy results show retention of secondary structure to extreme temperatures.
