In a recent study, nanocrystalline Ti-based alloys were synthesized using mechanical alloying (MA) followed by annealing. The alloying elements Nb or Nb and Zr were added to titanium. The mechanical properties and the corrosion resistance of these materials were investigated and compared with microcrystalline Ti and the TiAl6V4 alloy. An enhancement of the properties due to nanoscale structures...

The percolation theory is established as a useful tool in the field of pharmaceutical materials science. It is shown that percolation theory, developed for analyzing insulator–conductor transitions, can be applied to describe imperfect dc conduction in pharmaceutical microcrystalline cellulose during densification. The system, in fact, exactly reproduces the values of the percolation threshold ...

Paper/polyacrylic acid (PAA) composites were prepared using a microcrystalline cellulose (MCC)-reinforced PAA hydrogel. The MCC-reinforced PAA hydrogel was prepared by in-situ UV light-induced polymerization of acrylic acid in the presence of MCC. The experimental results showed that the presence of MCC improved the water absorption capacity of the resulting PAA hydrogel. The addition of 1 wt% ...

The main contribution of this article is to present hard evidence on hedging strategies and relate it to behavioural and agency problems resulting from speculation with derivatives. We focus on the case of Aracruz Celulose. We show how the real hedge position of Aracruz – that lost US$2.1 billion in currency derivatives – deviated from its optimal hedge as the result of speculation with Over-th...

Microcrystalline MoO 3 powder, possessing supercapacitive energy storage capability, shows interesting HF sensing performance with a high sensitivity of 6656 mF mM −1 g and low limit detection 1.2 μM.

The aim of the study was to investigate the physical stability of the semi-solid dispersions into the hard gelatine capsules prepared with Gelucire 44/14, Labrasol and different additives such as microcrystalline cellulose (MCC), mannitol and lactose (alpha-monohydrate) used for enhancing the stability of the formulations. The master dispersion prepared with only Gelucire 44/14 (20% w/w) and La...
