The development of green approaches for the biosynthesis of silver nanoparticles (AgNPs) is of prime significance in the field of nanotechnology research. A fast and eco-friendly protocol for the biosynthesis of extracellular AgNPs using culture supernatant (CS) from the fungus Cunninghamella phaeospora was studied in this work. This CS was proved as a potential new source for the extracellular...

This study aims to determine the optimum parameters for the invert sugar obtaining, using the acid hydrolysis at t oC. The inversion reaction has been applied to 3 samples of sugar solution of different concentration (P1: SU = 70%, P2: SU = 75%, P3: SU = 80%). For obtaining the invert sugar syrup, different inversion temperatures have been used (t1 = 80oC, t2 = 90oC, t3 = 100oC). The inversion ...

“Bloat”, a term that has existed in the technical community for many years, has recently received attention in the popular press. The term has a negative connotation implying that human, or system performance is diminished in some way when “bloat” exists. Yet “bloat” is seldom clearly defined and is often a catch-all phrase to suggest that software is filled with unnecessary features. However, ...

in this paper, we study spacelike dual biharmonic curves. we characterize spacelike dual biharmonic curves in terms of their curvature and torsion in the lorentzian dual heisenberg group . we give necessary and sufficient conditions for spacelike dual biharmonic curves in the lorentzian dual heisenberg group . therefore, we prove that all spacelike dual biharmonic curves are spacelike dual heli...

We present the effect of thermal treatments on the transduction behaviors of HCl-doped polyaniline (PANI) nanofibers integrated in conductometric devices upon exposure to 1% H2 (carried by N2). After drying in N2 at 25oC for 12 hours, devices showed a ~10% decrease in electrical resistance upon exposure to 1% H2. However, devices subject to 12-hour drying in N2 at 25oC followed by further therm...
