The designed peptides are amphipathic with an alternating hydrophilic−hydrophobic side chain pattern (Extended Data Fig.1d). Beyond the backbone β-strand hydrogen bonding, the peptide−binder interaction consists of somewhat separable solvent-exposed and solvent-shielded interfaces. The solvent-inacces...
Samples were submitted to tension perpendicular to the surface in order to quantify the adhesion of the fibers (Figure 11). The results (Table 3) indicate higher internal bonding for nanoclay-based mycelium composites (0.023 MPa) compared to the control sample (0.007 MPa). These results contrast...
This results in the relatively high sensitivity of ν [C(2)−H] to an increased participation of the imidazolium cation in the hydrogen bonding during the complexation. However, it is possible that β-CD also has OH vibrations that may overlap with H2O, and complicate the interpretation. In...
Six-year-old moso bamboo was used in this work. Bamboo was harvested in JiangXi Provience, China. The arc-shaped bamboo sheets were 1050 mm × 11 mm × 120 mm, and the surfaces of the bamboo sheets were smooth and no defects. The bamboo sheets were directly transformed by heat treatment...
As shown in Figure 20, we observed that Gly molecules associate with the SDS polar head of SDS via hydrogen bonding (shown by dashed lines), effectively increasing the size of the hydrophilic head of SDS molecules, which shifts the effective HLB. As found by Usol’tseva et al. [111], ...
Compounds with an LD50 between 2000 and 5000 mg/kg are considered potentially harmful if ingested (GHS hazard class V), while those with an LD50 between 300 and 2000 mg/kg are classified as harmful if ingested (GHS hazard class IV). Based on the LD50 values provided in Table 11, the ma...
Hydrogen bonding is the core of the action of NADESs, and the water content in the system will affect the viscosity of the NADES, which will have a significant impact on its extraction efficiency [28,30]. With the increase in the water content in the NADES, the extraction yields first ...
Versions Notes Abstract The formation of amyloid-like structures by metabolites is associated with several inborn errors of metabolism (IEMs). These structures display most of the biological, chemical and physical properties of protein amyloids. However, the molecular interactions underlying the assembly ...
. The most poignant spectral change caused by irradiation is the change in the intensity ratio of the amide I and amide II bands from 0.82 in the keratin/riboflavin sample to 1 in the keratin/riboflavin/irradiated sample. This change evidences the disruption of the intrinsic hydrogen bonding ...
Chemical bonding in nanotubes is composed entirely of sp2 bonds, which are stronger than the sp3 bonds found in alkanes and provide nanotubes with unique strength [40]. Interestingly, CNTs have much higher length-to-diameter ratio than other existing materials (i.e., up to 132,000,000:1) ...
