Piezoelectric biomaterials are intrinsically suitable for coupling mechanical and electrical energy in biological systems to achieve vivo real-time sensing, actuation, electricity generation. However, the inability synthesize align piezoelectric phase at a large scale remains roadblock toward practical applications. We present wafer-scale approach creating biomaterial thin films based on γ-glycine crystals. The film has sandwich structure, where crystalline glycine layer self-assembles...
The structures and physicochemical properties of acid-thinned corn, potato, rice starches were investigated. Corn, hydrolyzed with 0.14 N hydrochloric acid at 50 °C until reaching a target pasting peak 200—300 Brabender Units (BU) 10% solids in the Visco Amylograph. After modification amylose content decreased slightly all retained their native crystallinity pattern. Acid primarily attacked amorphous regions within starch granule both amylopectin simultaneously by acid. longer chain fraction...
The relationship between a low interlayer lateral force constant and ultrasmall potential energy corrugation in graphene/MoS<sub>2</sub> heterostructure provides another viewpoint to the origin of superlubricity.
Amorphous carbon is one of the most lubricious materials known, but mechanism not well understood. It counterintuitive that such a strong covalent solid could exhibit exceptional lubricity. A prevailing view lubricity amorphous results from chemical passivation dangling bonds on surfaces. Here we show instead arises shear induced strain localization, which, homogeneous deformation, dominates shearing process. Shear localization characterized by bond reorientation, phase transformation and...
The atomic-scale friction of the fluorographene (FG)/MoS2 heterostructure is investigated using first-principles calculations. Due to intrinsic lattice mismatch and formation periodic Moiré patterns, potential energy surface FG/MoS2 ultrasmooth interlayer shear strength reduced by nearly two orders magnitude, compared with both FG/FG MoS2/MoS2 bilayers, entering superlubricity regime. size dependency revealed as being based on relationship between emergence patterns ratio for heterostructures.
Atomic-scale friction in graphene oxide is investigated using density functional theory calculation including a long-range dispersion correction (DFT-D). The sliding behaviors between two layers with different groups or oxidation levels are quantitatively studied based on the constructed potential energy surfaces. Sliding paths minimum corrugations and corresponding static lateral forces shear strengths for systems derived, suggesting moderately higher compared graphene. effects of load...
Commercial maltodextrins derived from corn, potato, and rice starches were characterized for their chemical structures physicochemical properties. Rice maltodextrin consisted of more low molecular-weight (MW) saccharides potato high MW saccharides. Debranched had a significantly higher content with degree polymerization (DP) less than 10. On the other hand, debranched DP greater 20. protein lipid contents exhibited very viscosity at 40% concentration, which might be caused by retrograded...
The effects of the catalyst used in acetylation, including sodium hydroxide (NaOH), potassium (KOH), and calcium (Ca(OH)2), on chemical physicochemical properties acetylated waxy maize starch were investigated. Ca(OH)2-catalyzed exhibited a slightly higher pasting temperature lower β-amylolysis limit compared with prepared under NaOH or KOH catalysis, but no difference was observed for their thermal properties. carbohydrate profiles isoamylase-debranched starches β-limit dextrins...
The atomic-scale friction in fluorographene and graphane is investigated employing the density functional theory calculation including dispersion correction (DFT-D). Fluorographene exhibit low because of interlayer interaction induced by repulsive electrostatic forces between F or H atoms at interfaces. Moreover, owing to less electronegativity than atoms, variation spacing system energy corrugation, which predominantly determined during both loading sliding processes, as elucidated this...
Acetoin, a novel C<sub>4</sub> platform molecule derived from new ABE fermentation system was used as bio-based building block for the production of liquid hydrocarbon fuels.
This paper presents a detailed investigation of out-of-round electric locomotive wheels through extensive measurement conducted at field sites. More than 2000 wheels, seven types locomotives widely used in China, have been measured since April 2013. The results indicate that two freight traffic suffer serious polygonal wear problems with center wavelengths ranging from 160 to 315 mm. dominating wavelength is 200 Therefore, the investigations are mainly focused on types. other types, which...
