This review highlights the major advances in gecko‐inspired bioadhesives that relies mostly on van der Waals bonding forces. These are challenged by the moist environment of surgical settings that weaken adherence to tissue. The incorporation of nanoparticles in biomatrices and their role in tissue repair and drug delivery is also reviewed with an emphasis on procedures involving adhesives that are laser‐activated. Nanostructured adhesive devices have the advantage of being minimally invasive to tissue, can seal wounds, and deliver drugs in situ. All these tasks are very difficult to accomplish by sutures or staples that are invasive to host organs and often cause scarring.

Dramatic changes in molecular structure, degradation pathway and porosity of biochar are observed... more Dramatic changes in molecular structure, degradation pathway and porosity of biochar are observed at pyrolysis temperatures ranging from 250-550 °C, when bamboo biomass is pretreated by iron-sulfate-clay slurries (iron-clay biochar), as compared to untreated bamboo biochar. Electron microscopy analysis of the biochar reveals the infusion of mineral species into the pores of the biochar and formation of mineral nano-structures. Quantitative 13C Nuclear Magnetic Resonance (NMR) spectroscopy shows that the presence of the iron-clay prevents degradation of the cellulosic fraction at pyrolysis temperatures of 250 °C, whereas at higher temperatures (350-550 °C), the clay promotes biomass degradation, resulting in an increase in both the concentrations of condensed aromatic, acidic and phenolic carbon species. The porosity of the biochar, as measured by NMR cryo-porosimetry, is altered by the iron-clay pretreatment. In presence of the clay, at lower pyrolysis temperatures, the biochar deve...

Biocompatible adhesives are at the forefront of this “surgical revolution” as fi brin, polyethylene glycol and cyanoacrylate glues are currently used in clinical procedures. Other experimental adhesives appear to be very promising; in particular, those that mimic natural mechanisms of adhesion and are light-activated or incorporate nanoparticles and nanostructures

Solid-state 27 Al multiquantum MAS NMR experiments proved unambiguously that most of the Al V species formed independently from the alumina phase are accessible for guest molecules on the surface and are mainly transferred to Al VI species after water adsorption, which are structurally similar to surface Al IV species. The NMR chemical shifts and their coordination transformation with and without water adsorption are confirmed by DFT calculations of the predicted clusters. The Al Vrich ASA has been examined in the dehydration of glucose to 5-hydroxymethylfurfural (HMF). It provided two times higher HMF yield than Al VI-rich ASA, and an even higher one than metaldoped zeolites. This remarkable performance is attributed to a high Al V content promoting the surface Brønsted and Lewis acidity in the ASA. Therefore, the discovery presented here not only provides fundamental knowledge of the nature of aluminum coordination, but also paves the way for developing highly efficient catalysts.

Solid state NMR provided insight into the structural features of the POPs, while in situ solid state Vis-NIR and electron paramagnetic resonance spectroelectrochemistry showed that the distinct redox states in POP-S could be reversibly accessed. The development of redox-active porous organic polymers with heterocyclic linkers affords their potential application as stimuli responsive materials in gas storage, catalysis, and as electrochromic materials.
