Environmentally adaptive hydrogels have great potential as soft robotics but achieving self-regulated reversal shape deformation in homogenous hydrogels under a constant stimulus is challenging. Here, the authors report responsive hydrogels functionalized with two photoswitchable spiropyrans that exhibit self-reg...
atom first (Fig.1b) [39]. After the generation and release of distant NH3, the nitrogen atom bound on the catalyst surface begins to form the second NH3in a similar route. Regarding the alternative path, protons are introduced successively onto the two nitrogen atoms and the two NH3molecules...
The C27-C29 regular steranes in mass chromatograms (m/z = 217) were distributed in a similar “V” shape (Fig. 13A, E, G, I). These results demonstrate that the oil in the SSFL was sourced from the thermal evolution of organic matter in the adjacent ORL. The same result was ...
Unfortunately, the amorphous nature of these materials can yield significant pore size dispersities, inhibiting their utilization in certain applications such as size- and shape-based gas separation and storage2,11. Crystallinity, in contrast, is characterized by ordered structure and uniform porosity,...
Technology has and continues to shape how we view teaching, learning, and assessing students. The fourth industrial revolution has pushed us to look beyond traditional sources of knowledge to see how we can enhance student capacity to make them future-ready. Where artificial intelligence is ...

The coherence length was calculated using the Scherrer equation: CL = 2πK/Δq, where Δq is the full width at half-maximum of the peak and K is a shape factor (0.94 was used here). The azimuthal angle was defined to be ω, which is the angle with respect to the qz axis. The ...
7, Fig. 8 respectively with a Pure Lorentzian band shape. The computed and experimental wavenumbers and their assignments are presented in Table 7. The title molecule has 26 atoms leading to 72 fundamental vibrations which show CS and C1 point group symmetry with all the vibrations active in ...

X-ray study showed the tendency to form lamellas in the case of SL2 as an effect of the presence of two terminal perfluorinated alkyl chains connected to a polar mobile aromatic core, which resulted in microsegregation. Additionally, TiO2 influences the energy gap and HOMO–LUMO levels of ...
