The implementation of cost-effective and sustainable biorefineries to substitute the petroleum-based economy is dependent on coupling production bioenergy with high-value chemicals. For this purpose, US Department Energy identified a group key target compounds be produced from renewable biomass. Among them, 5-hydroxymethylfurfural (HMF) can obtained by dehydration hexoses present in biomass an ...

In 1991 Ferri, Faccio and D’Amico introduced and investigated two numerical triangles, called the DFF and DFFz triangles. Later Trzaska also considered the DFF triangle. And in 1994 Jeannin generalized the two triangles. In this paper, we focus our attention on the generalized Fibonacci, Lucas, Pell, Pell-Lucas, Jacobsthal and Jacobsthal-Lucas polynomials, and several numerical triangles deduce...

• An electrochemical method for sensitive and selective determination of 2,5-diformlyfuran. Accurate in situ monitoring the photocatalytic oxidation 5-hydroxymethylfurfural to A platform improved reforming processes by means sensor technology. As need methods convert biomass into value-added compounds increases, so too does requirement complementary rapid methods. In this study, first time, an ...

We describe the low energy excitations of the diquark condensates in the color-flavor locked phase of QCD with three massless flavors, at high baryon densities, in terms of a non-linear effective lagrangian. Such a lagrangian is formally seen to correspond to the lagrangian for the hidden gauge symmetry description of the effective low energy chiral lagrangian, the role of the hidden symmetry b...

Reductive amination of 2,5-diformylfuran (DFF) was used to implement the transition from bio-derived 5-hydroxymethylfurfural (HMF) to pharmaceuticals. The synthesized bis(aminomethyl)furans were utilized as building blocks for the construction of new derivatives with structural cores of naturally occurring biologically active compounds. Using the one-pot procedure, which included the Diels-Alde...

I present a theoretical discussion of the uncertainties related to the QCD analysis of the proton structure function F2(x,Q) at small x. The role played by the ‘unphysical’ gluon density is pointed out. It is shown how the study of more observables can reduce the theoretical uncertainty and, in particular, an alternative method of analysis, based on the introduction of physical anomalous dimens...

BACKGROUND Although extensive caspase-3 activation has been demonstrated in experimental brain ischemia produced in neonatal rat, the role this caspase plays in the focal ischemia of adult brain is not clear, as the levels of caspase-3 in adult rat brain are extremely low. This raises the question whether caspase-3 synthesis and activation are essential for execution of the apoptotic program an...

We analyze the free energy and construct the Gibbs-KMS states for a class of quantum lattice systems, at low temperature and when the interactions are almost diagonal in a suitable basis. We study systems with continuous symmetry, but our results are valid for discrete symmetry breaking only. Such phase transitions occur at intermediate temperatures where the continuous symmetry is not broken, ...

Left-right asymmetries have been noted in tasks requiring the classification of many visual stimuli, including Navon figures, spatial frequency gratings, and faces. The Double Filtering by Frequency (DFF) model (Ivry & Robertson, 1998), which postulates asymmetric frequency filtering on task-relevant frequency bands, has been implemented to account for asymmetric processing of each stimulus typ...
