Silk’s supercontraction results from its hierarchical structure consisting of water-penetrable amorphous domains crosslinked by stable β-sheet crystalline domains. The highly oriented polymer chains in the amorphous domains are fixed by hydrogen bonds. Water from wetting breaks these bonds and induces ...
First, the copper sheet is cut into the desired pattern (Fig. 3a) using diode-pulsed solid state (DPSS) laser. Next, vertical walls around the foot pad base are manually folded by 90° under a microscope (Fig. 3a). Then we solder the foot pad using 51-gauge quadruple insulated wire ...
3). The ds_dimensions function defines the spatial and temporal dimensions of the WaterpyBal NetCDF dataset, whose boundary conditions can be determined by defining the limits manually, using an array, a datasheet containing all latitude and longitudes, a raster, or a NetCDF dataset as a ...
The absorbent structure of the invention is typically positioned in between the topsheet and backsheet. Preferred backsheets are vapour pervious but liquid impervious. Preferred topsheet materials are at least partially hydrophilic; preferred are also so-called apertured topsheets. Preferred may be that...

(1) Transition metal basic salt consisting of NO3−has a formula of M2(OH)3NO3, which is also known as transition metal nitrate hydroxides (TMNHs) [110]. This type of basic salts have two distinct structures [111]. For the single layered M2(OH)3NO3, its structure consists of brucite...
