Catalytic conversion of 5-hydroxymethylfurfural (5-HMF) over Pd-Ru/FAU zeolite catalysts
(Elsevier, 2021)"We present this study on FAU-type zeolites were prepared varying the Si/Al ratio (4, 5 and 6) and crystallization time (4, 6 and 8?h) to produce a highly pure and homogeneous material with enhanced surface area values. ... -
Biodegradation of diisononyl phthalate by a consortium of saline soil bacteria: optimisation and kinetic characterisation
(Springer, 2021)"Diisononyl phthalate (DINP) is one of plasticisers most employed in the production of plastic materials and belongs to the most important environmental contaminants. In this work, a consortium of saline soil bacterial ... -
Multifractal analysis of the symmetry of a strictly isospectral energy landscape on a square lattice
(Elsevier, 2021)"We use the Höder regularity analysis to study the symmetry breaking and recovery due to a parametric potential generated via the strictly isospectral factorization method. The initial potential is two-dimensional and ... -
Biocompatibility of nitrogen-doped multiwalled carbon nanotubes with murine fibroblasts and human hematopoietic stem cells
(Springer, 2019)Chemical vapor deposition (CVD) methods to create carbon nanotubes (CNTs) with specific dopant atoms have been of interest in biomedical applications due to the relative ease of synthesis of doped CNTs with controlled ... -
Diminution of migration of phthalic acid esters in tequila beverage by the year of production
(Taylor & Francis, 2020)"The presence of diethyl-phthalate (DEP), dibutyl-phthalate (DBP), butylbenzyl-phthalate (BBP), diethylhexyl-phthalate (DEHP) and diisononyl-phthalate (DINP) was determined in 295 tequila samples. They were grouped by age ... -
Consensus Stability of a Large Scale Robotic Network under Input and Transmission Delays
(IEEE, 2021)"A large scale network of differential-wheeled robots seeking consensus is considered in the presence of input and transmission delays. Consensus stability of this nonlinear network dynamics holds if its linear part can ... -
Coproduction of hydrogen, ethanol and 2,3-butanediol from agro-industrial residues by the Antarctic psychrophilic GA0F bacterium
(Elsevier, 2020)"In this study, the simultaneous production of hydrogen, ethanol, and 2,3-butanediol was assessed using three agro-industrial residues: cheese whey powder (CWP), wheat straw hydrolysate (WSH) and sugarcane molasses (SCM), ... -
Autodisplay of an endo-1,4-?-xylanase from Clostridium cellulovorans in Escherichia coli for xylans degradation
(Elsevier, 2021)"In this work, the scale-up from 0.01 to 10 L process for the co-production of hydrogen (H2) and ethanol (EtOH) by a genetically engineered Escherichia coli that utilizes hemicellulosic hydrolysates from wheat straw ... -
Scale-up of hydrogen and ethanol co-production by an engineered Escherichia coli
(Elsevier, 2021)"In this work, the scale-up from 0.01 to 10 L process for the co-production of hydrogen (H2) and ethanol (EtOH) by a genetically engineered Escherichia coli that utilizes hemicellulosic hydrolysates from wheat straw ... -
Autodisplay of alpha amylase from Bacillus megaterium in E. coli for the bioconversion of starch into hydrogen, ethanol and succinic acid
(Elsevier, 2020)"In this work, the expression of an alpha-amylase from Bacillus megaterium on the cell surface of Escherichia toll strains WDHA (Delta hycA and Delta ldhA) and WDHFP (Delta hycA, Delta frdD and Delta pta) by the autodisplay ... -
Superfluid Rayleigh–Plesset extension of FLRW cosmology
(Elsevier, 2021)"Guided by the analogy with the Rayleigh–Plesset dynamics of multielectron bubbles in superfluid He-4, we consider the cosmological FLRW evolution equation with additional cubic and sixth powers of the inverse of the scale ... -
