Binder drainage test is widely used to set an upper limit to the design binder content of porous asphalt. However, the presence of high amount of fine particles in the drained binder may affect the accuracy of the test result. This paper presents a study to characterize the composition and particle size distribution of fine particles accumulated in the drained binder. Fine aggregates and filler...

Gas evolved from the thermal decomposition of the binder can greatly deteriorate the quality of sand castings. Binder gas models used in casting simulations require knowledge of the binder gas mass and molecular weight evolution, but available data are limited. In the present study, the mass and molecular weight of gas evolved from phenolic urethane no-bake (PUNB) bonded sand are measured as a ...

Electrospinning offers a powerful route for building one-dimensional (1D) micro/nanostructures, but a common requirement for toxic or corrosive organic solvents during the preparation of precursor solution has limited their large scale synthesis and broad applications. Here we report a facile and low-cost way to prepare 1D porous carbon microfibers by using an electrospun fiber-like natural pro...

To evaluate whether the increase in serum transcobalamin I, seen in patients with carcinoma, is caused by synthesis of R-binder to tumour cells, the distribution of vitamin B12 R-binder in 125 malignant growths of the digestive tract was studied. Positive staining for R-binder with immunoperoxidase was observed in 85 (70%) carcinomas. Positive staining for R-binder was observed in all four chol...

Zeolite-based catalyst bodies are commonly employed in a range of important industrial processes. Depending on the binder and shaping method chosen, vast differences in the reactivity, selectivity and stability are obtained. Here, three highly complementary micro-spectroscopic techniques were employed to study zeolite ZSM-5-binder interactions in SiO2-, Al2O3-, SiO2 : Al2O3- (2 : 1 mix) and kao...

Porous organic–inorganic materials with tunable textural characteristics were synthesized using the topdown process by intercalating silsesquioxanes and polyhedral oligomeric siloxanes of different types between crystalline zeolite-derived layers. The influence of key parameters such as (i) linker nature (pure hydrocarbon, S-, N-containing); (ii) chain length in alkyland aryl bis(trialkoxysilyl...
