The mechanism of the asymmetric hydrogenation of methyl (Z)-2-acetamidocinnamate (mac) catalysed by [Rh(MonoPhos)(2)(nbd)]SbF(6) (MonoPhos: 3,5-dioxa-4-phosphacyclohepta[2,1-a:3,4-a']dinaphthalen-4-yl)dimethylamine) was elucidated by using (1)H, (31)P and (103)Rh NMR spectroscopy and ESI-MS. The use of nbd allows one to obtain in pure form the rhodium complex that contains two units of the liga...

Intra-caecal fermentation parameters in caecally ®stulated ponies offered ®brous diets of diverse botanical origin were examined in two experiments, A and B. In Experiment A three ponies were offered ca. 4 kg dry matter (DM) per day of either ground, pelleted hay cubes (HC), a 67:33 mix of oat hulls:naked oats (OH:NO) or a 75:25 mix of unmolassed:molassed sugar beet feed (SBF), whilst in Experi...

Motivated by the environmentally driven energy transition we live in, valorization of biomass residues from agro-industry as renewable can play an essential role in GHG emissions mitigation. To overcome debate on production and use solid biofuels (SBF), this study, apply integrated multicriteria tool for assessment sustainability agro-industrial (AIR) biofuels. Mexico has a vast AIR production,...

This work studied the corrosion behaviour of Ti-12Mo-6Zr-2Fe alloy with different surface conditions: untreated and chemically treated (CST), anodised nanotubes (Nt) nanopores (NP). These samples were immersed in simulated body fluid (SBF) for 1, 7, 14 days. Samples Nt NP displayed higher resistance lower passivation current (ipass) than CST after days resting SBF. Furthermore, traditional equi...

This paper presents a case study in which a middle school science teacher modifies her classroom instruction and teaching materials using the Structure, Behavior, and Function (SBF) representational framework to transfer her reasoning about one natural system (an aquarium ecosystem) to another natural system (human cells and body systems). Promoting an understanding of complex systems is a diff...

We compare infrared surface brightness fluctuation (IR SBF) distances measured in galaxies that have hosted type Ia supernovae (SNIa) to estimated from SNIa light curve fits. show the properties of found IR SBF hosts are very different those exploding Cepheid calibrators, therefore, this is a direct test systematic uncertainties on estimation Hubble constant (Ho) using supernovae. The results J...

Dense, polycrystalline, synthetic hydroxyapatite (HA) was incubated for 36 days in modified simulated body fluid (SBF) with increased HCO3 and reduced Cl ion concentrations (27 and 120 mM, respectively) closer to actual blood plasma than typical SBF. The resulting precipitated apatite layer was characterized by X-ray photoelectron spectroscopy (XPS) and contact angle measurements and found to b...
