were prepared by soft chemical exfoliation of layered lepidocrocite-type titanate crystals57,58. As illustrated in Fig.2a, the nanosheet is a single-crystal-like 2D ultrathin monolayer (0.75 nm thickness) with a high density of Ti vacancies59. The Ti atomic vacancy is ...
yield strength (73 MPa) and Young’s modulus (1 GPa). These values are similar to those of thermoplastics such as polyethylene, yet unlike thermoplastics, the glassy gels can be deformed up to 670% strain with full and rapid recovery on heating. These transparent materials form by a one-s...
In case of POM-d2, the left and right figures show the density distribution in the higher and lower height region, respectively. Structure Analysis using WAND Data Figure 4(a) and 4(b) show, respectively, the full- rotation WAND diagrams taken for POM-h2 and POM-d2 at room temperature...

A couple of slides ago, we showed a phase image differentiating the layers of low and high density polyethylene, where the topography image did not. On this slide, we have a 10 µm x 5 µm image of a tire tread with topography on top and phase on bottom. In the topography image...
LRL Helios nuclear pulse unit segment of the spherical unit The nuclear pulse units were one meter in diameter. The core is a 2 kg sphere of weapons-grade uranium. It is coated by 5 kg of high density chemical explosive, and the entire clanking mess is jacketed by 15.7 kg of low dens...
A composite high density concrete, or alternatively, a laminated graded-Z shield, 24 units thick of which 16 units are iron and 8 units are polyethylene containing boron (BPE), and additional mass behind it to attenuate neutron capture gamma rays, is more effective than just 24 units of pure...
transformations result in gradually increased bandgap, which is confirmed by scanning electron microscope cathodoluminescence (SEM-CL) experiments and validated by density functional theory (DFT) calculations. The direct visualization of the structure and degradation process at the atomic scale provides ...
However, as Gray points out, the exact mechanism of ion conduction in a solventless polymer is as yet unknown. Recent events have highlighted the importance of safety for high energy density batteries, such as lithium and magnesium rechargeable systems. To date such batteries involve the use of...
