This study investigated the inhibition of enzymatic hydrolysis by unbound lignin (soluble and insoluble) with or without addition metal compounds. Sulfonated, Organosolv, Kraft were added in aqueous enzyme−cellulose systems at different concentrations before hydrolysis. The measured substrate digestibility (SED) cellulose was decreased 15% when SL to a concentration 0.1 g/L due nonproductive adsorption enzymes onto lignin. Cu(II) Fe(III) found inhibit presence Ca(II) Mg(II) reduce eliminate...
Abstract Thermal and rheological properties of various blends gelatinized starch biodegradable polyester, polycaprolactone (PCL) or poly(butylene succinate adipate) (PBSA), were studied by DSC, TGA rheometry. Methylenediphenyl diisocyanate (MDI) was used as a compatibilizer distributed in different phases through controlled processing. The addition MDI showed stronger effect on thermal when it mainly the polyester phase prior to blending. Starch shown increase shear viscosity both types...
Abstract Starch-based superabsorbent polymers (SAPs) were produced by graft copolymerization of starch-g-acrylamide using a twin-roll mixer as reactor. This work focused on the effect starch microstructure (amylose/amylopectin contents) from same source (corn starch) ratio (GR), efficiency (GE) and Add-on (AO), well water absorption capability (WAC) SAPs, which investigated FTIR, NMR, gravimetric TGA. The torque variation represented all processing in reactor, including compress,...
The role of the macrophage in destruction virulent treponemes is disputed. A major obstacle has been inability to demonstrate quantitative phagocytosis by macrophages. Treponema pallidum pertenue was attached polycarbonate filters for assessment treponemal disappearance due measured enumeration with immunofluorescence. Resident and lipopolysaccharide-activated macrophages were found phagocytize equally well. killed enhanced opsonization immune serum. Macrophages successfully phagocytized...
Scanning tunneling microscopy and optical spectroscopy techniques have been utilized to investigate the formation of ordered organic monolayer films on (001) face silicon.Cyclopentene 1,5-cyclooctadiene both produce that are translationally rotationally.The rotational orientations molecules arise from directional interaction π orbitals starting alkene with orbital dimers comprising reconstructed Si(001) surface, surface acting as a template for determining directionality in subsequent...
Summary To solve the problem of annular gas channeling in natural well cementing, isoprene rubber was used as graft matrix material, absorbing methyl methacrylate and octadecyl acrylate were functional monomers, a gas-inspired expansion polymer prepared by copolymerization, gas-triggered self-repair cementing slurry developed. The structure gas-sensitive grafted characterized Fourier transform infrared (FTIR) 1H nuclear magnetic resonance (NMR), effects monomer concentration copolymer feed...
This paper reports an imaging system inspired from the eyes of elephantnose fish for detection objects in low-light environment. Our bioinspired approach realizes broad-spectrum (wavelength 350 nm ~ 1000 nm) micro-photocollectors onto image sensors to increase their overall sensitivity by more than 3.5 times. The novel fabrication process that creates on curved surfaces can be applied fabricate other 3D microstructures.
