A series of ZnO: Sm films with Sm content of 0-1.0 at.% were deposited by a chemical solution deposition. The deposited films were characterized by X-ray diffraction, field emission scanning electron microscopy, UVVis and luminescent spectrophotometry, and electrical resistance measurement. The experiments revealed that the Sm doping first increased and then decreased the optical transmittance, band gap, and n-type conductivity with increasing Sm content. The film with the Sm content of 0.75 at.% showed optimal optical and electrical properties. The maximal band gap widening was about 0.19 eV. The resistance decrease of *20 times was observed. The photoluminescence measurement indicated that the films showed a strong near band gap emission and a blue-green emission related to intrinsic defect. The refractive index, extinction coefficient, and dielectric constant of the films were calculated with the transmittance and reflectance spectra.

“…The self-healing behavior of AgNP@GCOL/PAA was further confirmed by a conductivity test (Figure d). First, the effect of AgNPs on the conductivity of the hydrogels was investigated using the four-probe method, and the results can be referred to Table S2. Because of the dissociation of carboxyl groups, the pristine PAA hydrogel exhibited a weak conductivity, while AgNP@GCOL/PAA with an AgNO 3 dose of 50 mg/mL possessed a conductivity more than three times that of pristine PAA, and also higher than those of chitosan/polyacrylamide and gelatin/polyvinyl alcohol (∼4 mS/cm), , which indicated that the presence of AgNPs greatly promotes the electrical conductivity.…”

Recently, versatile hydrogels with multifunctionality have been widely developed with emerging applications as wearable and implantable devices. In this work, we reported novel versatile hydrogels by self-catalyzing the gelation of an interpenetrating polymer network consisting of acrylic acid (AA) monomers and GA-modified collagen (GCOL) in situ decorated silver nanoparticles (AgNPs). The resultant hydrogel, namely AgNP@GCOL/PAA, has many desirable features, including good mechanical properties (such as 123 kPa, 916%, and 1961 J m−2 for the fracture stress, strain and tearing energy) that match with those of animal skin, excellent self-healing performance, favorable conductivity and strain sensitivity as a flexible biosensor, and excellent antibacterial and anti-UV properties, as well as the strong adhesiveness on skin. Moreover, AgNP@GCOL/PAA showed excellent biocompatibility via in vitro cell culture. Remarkably, AgNP@GCOL/PAA displayed superior hemostatic properties with sharply decreasing blood loss for a mouse liver incision, closely related to its strong self-adhesion which produced anchoring strength to the bleeding site and thus formed a network barrier with liver tissue. This study provides new opportunities for the facile preparation of widely used multifunctional collagen-based hydrogels based on a simple pyrogallol-Ag system.

“…However, we did not observe remarkable crystallization for Al 9.00 ZnO even after annealing at 500 • C. The extra peaks that can be attributed to deviation from single crystal phase were not observed. In the literature, as a negative effect of annealing process some peaks such as the ones that originate from (1 0 0) and (1 0 1) planes of polycrystalline structured Würtzite ZnO lattice [17,18] or Al 2 O 3 and metallic Al phase characteristic peaks [19] were registered from annealed samples.…”
