Abstract Recovery of bioactive compounds from biowaste is gaining more and interest in circular economy models. The oilseed cakes are usually insufficiently exploited by most technologies since they represent valuable matrices abundant proteins, minerals, phytochemicals, but their use mostly limited to feed ingredients, fertilizers or biofuel production. This study was thus focused on the explo...

The biological flux and lifetime of methanol in anoxic marine sediments are largely unknown. We herein reported, for the first time, quantitative methanol removal rates in subsurface sediments. Anaerobic incubation experiments with radiotracers showed high rates of microbial methanol consumption. Notably, methanol oxidation to CO2 surpassed methanol assimilation and methanogenesis from CO2/H2 a...

We discuss recent results on the scattering/blow-up dichotomy below the ground state threshold for the focusing nonlinear Schrödinger equation with an inverse-square potential and a nonlinearity that is mass-supercritical and energy-subcritical.

We generalize previous uniqueness results on a semilinear elliptic equation with zero Dirichlet boundary condition and superlinear, subcritical nonlinearity. Our proof is based on a bifurcation approach and a Pohozaev type integral identity, which greatly simplifies the previous arguments.

We report an example of subcritical wave instability in a model of a reaction-diffusion system and discuss the potential implications for localized patterns found in experiments on the Belousov-Zhabotinsky reaction in a microemulsion.

Wheat bran is a major by-product of cereal production that still has limited use for advanced nutritional and material applications. A sequential process using subcritical water, membrane filtration and selective enzymatic treatments has been designed for the combined fractionation of functional high molar mass hemicelluloses (over 10 g mol) and oligosaccharides from wheat bran. This process no...

Subcritical water is an alternative and environmentally friendly processing medium with interesting applications in many fields of research1. Its ability to degrade natural biopolymers2 (cellulose, protein etc.) into smaller, usually water-soluble products (sugars, amino acids etc.) has been found to be quite useful, especially in waste and biomass processing technologies. Nevertheless, for foo...

Most criticality safety calculations are performed using Monte Carlo techniques because of Monte Carlo’s ability to handle complex three-dimensional geometries. For Monte Carlo calculations, the more histories sampled, the lower the standard deviation of the resulting estimates. The common intuition is, therefore, that the mo re histories, the better; as a result, analysts tend to run Monte Car...

The critical conditions for vigorous burning of spherical carbón partióles are derived using asymptotic techniques for large Zel'dovich numbers. The particle liíetime and the temperature history are obtained for both supercritical and subcritical regimes, when a carbón particle is suddenly exposed to a stagnant high temperature oxidizing atmosphere. For Damkóhler numbers below a critical number...

effect of methanol concentration and channel depth of bipolar plates on the performance of single direct methanol fuel cell was investigated experimentally. the membrane used in this experiment was nafion117. dimension of the single cell were 10cm 10 cm. methanol concentrations of 0.50, 1.0, 1.5, 2.0, 3.0 molar were used. channel depth of the bipolar plates were chosen to be 1.0, 1.5, 2.0 mm, a...
