TL;DR: The magnetic chitosan nanoparticles of 13.5nm were prepared as a magnetic nano-adsorbent by the carboxymethylation of chitosa and the followed binding on the surface of Fe 3 O 4 nanoparticles via carbodiimide activation as discussed by the authors.
Abstract: The magnetic chitosan nanoparticles of 13.5 nm were prepared as a magnetic nano-adsorbent by the carboxymethylation of chitosan and the followed binding on the surface of Fe 3 O 4 nanoparticles via carbodiimide activation. Their saturation magnetization, remanent magnetization, coercivity, and squareness were 62 emu/g, 1.8 emu/g, 6.0 Oe, and 0.029, respectively, reflecting their superparamagnetic property. The binding reaction of carboxymethyl chitosan on the surface of Fe 3 O 4 nanoparticles was much faster than the self-crosslinking of carboxymethyl chitosan, and the appropriate reaction time was 1 h. At low carboxymethyl chitosan concentrations, the binding efficiency could be as high as 100%. The maximum amount of chitosan bound on the Fe 3 O 4 nanoparticles was 4.92 wt%. In addition, magnetic chitosan nano-adsorbent was shown to be quite efficient for the fast removal of Co(II) ions at pH 3–7 and 20–45 °C. The maximum adsorption capacity for Co(II) ions occurred at pH 5.5, and the adsorption process was exothermic in nature with an enthalpy change of −12.04 kJ/mol. The equilibrium was achieved within 1 min, and the adsorption data obeyed the Langmuir equation with a maximum adsorption capacity of 27.5 mg/g (557 mg/g based on the weight of chitosan) and a Langmuir adsorption equilibrium constant of 0.034 l/mg at 25 °C. Such fast adsorption rate and high adsorption capacity could be attributed to the absence of internal diffusion resistance and the high specific surface area.

TL;DR: In this paper, it was shown that the logarithmic and linear singularities occurring at small momentum fractions of light meson distribution amplitudes do not exist in a self-consistent perturbative analysis, which includes threshold resummations.
Abstract: We calculate the $B\to\pi,\rho$ transition form factors in the framework of perturbative QCD to leading power of $1/M_B$, $M_B$ being the $B$ meson mass. We explain the basic principle by discussing the pion electromagnetic form factor. It is shown that the logarithmic and linear singularities occurring at small momentum fractions of light meson distribution amplitudes do not exist in a self-consistent perturbative analysis, which includes $k_\perp$ and threshold resummations.

TL;DR: In this article, the authors investigated the thermogravimetric analysis of high-ash sewage sludge using thermodynamic analysis and showed that the activation energy and preexponential factor from mass loss data using five major reaction mechanisms showed positive ΔH except F1.5.

TL;DR: In this article, two novel flame-retardant curing agents for epoxy resins, [ODOPM-PN] and [ ODOPM−MPN], were prepared from phenol formaldehyde novolac (PN), melamine-phenol (MPN) and a reactive 2-(6-oxid-6H-dibenz) 6-methanol methanol (ODOPm) while ODOPm was synthesized through the reaction between 9,10-dihydro-9-oxa-10-ph
