A novel multi-functional plate-like lamination that combines a thermal energy storage capability with a structural capability is described. The lamination consists of a paraffin impregnated porous graphitic core (the energy storage volume) encapsulated between rigid graphite/epoxy composite skins. Heat storage is via solid-liquid phase transition of the paraffin. Stacked laminations form a sand...

170 patients admitted to shariaty hospital pulmonary ward were studied for pulmonary nocardiosis during 17 months (aug 1990-jan 1992). paraffin baiting was used and nocardia asteroides isolated in five cases from sputum, pleural fluid and bronchial washing. the technique used in this study inhibits growth of other organism and yeast and is reliable, simple and cheap for isolation of nocardia fr...

Hybrid propellants are of great interest in space propulsion for combining desirable characteristics of solid and liquid propulsion technologies: simplicity and operational readiness (from solid) with variable thrust and high performance (from liquid), minimizing the disadvantages associated with each one. However, a hybrid propulsion was always limited to the low rate of burning of its solid f...

To substitute for petroleum, Fischer-Tropsch synthesis (FTS) is an environmentally benign process to produce synthetic diesel (n-paraffin) from syngas. Industrially, the synthetic gasoline (iso-paraffin) can be produced with a FTS process followed by isomerization and hydrocracking processes over solid-acid catalysts. Herein, we demonstrate a cobalt nano-catalyst synthesized by physical-sputter...

OBJECTIVE Mutation status of the KRAS gene in tumors has been shown to be a predictive biomarker of response to anti-epidermal growth factor receptor antibody therapy in patients with metastatic colorectal cancer. This retrospective analysis examined the association between efficacy and safety of the fully human anti-epidermal growth factor receptor antibody panitumumab and KRAS mutation status...

Autophagy assures cellular homeostasis, and gains increasing importance in cancer, where it impacts on carcinogenesis, propagation of the malignant phenotype and development of resistance. To date, its tissue-based analysis by immunohistochemistry remains poorly standardized. Here we show the feasibility of specifically and reliably assessing the autophagy markers LC3B and p62 (SQSTM1) in forma...

We have micromachined and tested the first paraffin–PDMS composite thermal microactuator having multi shot large vertical displacement capabilities (~160 μm for 1 mm diameter device). A solid to liquid phase change of trapped paraffin into the PDMS is used to create a large volume dilatation of the composite (18%, for a temperature varied from 20 to 80 °C). The elasticity of the PDMS ensures th...

Titanium dioxide (TiO2) nanofibers have been widely applied in various fields including photocatalysis, energy storage and solar cells due to the advantages of low cost, high abundance and nontoxicity. However, the low conductivity of ions and bulk electrons hinder its rapid development in lithium-ion batteries (LIB). In order to improve the electrochemical performances of TiO2 nanomaterials as...
