The microscale magnesium metal organic framework-74 (m-MgMOF74) and its nano-modified particles (n-Mg-MOF74) were successfully synthesized. The n-Mg-MOF74 exhibited better biocompatibility and could act simultaneously inside and outside the cell while m-Mg-MOF74 only stayed extracellularly. Further, in vitro and in vivo angiogenic and osteogenic studies of m/n-MgMOF74 were evaluated and provided evidence that n-Mg-MOF74 was worthy of applications in tissue engineering.

This work reveals the thickness dependence of the wrinkling behaviors of plasma-treated polydimethylsiloxane (PDMS) films. For thick films, the wrinkles can be predicted by the classic nonlinear finite mechanics, giving rise to brilliant structural colors. For thin films, the wrinkles are large and random. These observations provide new opportunities for understanding the wrinkling mechanics and have promising applications in smart optical materials.

The stability of Li@atomic layer deposition (ALD)-carbon nanotube sponge (CNTS) electrodes relies on both the high-surface-area conductive framework and the robust ALD-Al2O3 surface protection layer, which decreases the effective areal current density and stabilizes the electrode/electrolyte interface for Li nuclei,respectively.

Near-infrared (NIR)-controlled cell adhesion: We constructed an NIR-responsive nano-biointerface by introducing a thermal responsive polymer onto a silicon nanowire array with photothermal property. The prepared nano-biointerface showed NIR-controlled reversible cell adhesion and release without the assistance of photosensitive moieties.
