“…It is noteworthy that, in spite of the total N content of Co@ N ‐C(g)‐H was as high as 11.5 %, it only achieved a low activity in the oxidative esterification, indicating that the acid treatment of CoO x @ N ‐C(g) caused the decrease of the amount of basic sites. In previous studies, furan, pyrrole, and thiofuran derivative heterocyclic compounds can be polymerized via oxidative dehydrogenation under acidic conditions or using acidic catalysts . In our case, the oxidative esterification of furfural was performed without any alkali or acid additives, avoiding the polymerization of furfural.…”

It is an attractive and challenging topic to endow non‐noble metal catalysts with high efficiency via a nitrogen‐doping approach. In this study, a nitrogen‐doped carbon catalyst with high nitrogen content encapsulating cobalt NPs (CoOx@N‐C(g)) was synthesized, and characterized in detail by XRD, HRTEM, N2‐physisorption, ICP, CO2‐TPD, and XPS techniques. g‐C3N4 nanosheets act as nitrogen source and self‐sacrificing templates, giving rise to an ultrahigh nitrogen content of 14.0 %, much higher than those using bulk g‐C3N4 (4.4 %) via the same synthesis procedures. As a result, CoOx@N‐C(g) exhibited the highest performance in the oxidative esterification of biomass‐derived platform furfural to methylfuroate under base‐free conditions, achieving 95.0 % conversion and 97.1 % selectivity toward methylfuroate under 0.5 MPa O2 at 100 °C for 6 h, far exceeding those of other cobalt‐based catalysts. The high efficiency of CoOx@N‐C(g) was closely related to its high ratio of pyridinic nitrogen species that may act as Lewis basic sites as well as its capacity for the activation of dioxygen to superoxide radical O2.−.

“…Light attenuation within the material due to absorption by monomers and photoinitiators, scattering by filler particles and refraction at the filler/monomer interface is the cause of this limitation. As preponderant phenomenon, the light scattering jeopardizes light transmission and consequently, affects the conversion and depth of cure . Experimental results have demonstrated that the scattering coefficient decreases and the transmission efficiency improves when the refractive index difference between resin and filler narrows .…”

Photopolymerization of an Epoxy Resin: Conversion and Temperature Dependence of its Refractive Index

Obtaining photocomposite materials with predefined optical properties requires a good knowledge of the refractive index evolution of the photopolymerizable media. In this aim, relationships between refractive index and conversion in the course of an epoxy resin photopolymerization are first established due to real time refractometric and infrared spectroscopic techniques. Refractive index value increases with conversion as long as the photocured material is not in glassy state. A shift of the relationship toward lowest refractive index values is observed when the reaction temperature increases. Second, the final photocured materials previously obtained are characterized. It is highlighted that the higher the photocuring temperature, the higher the epoxy conversion but the lower the material density at room temperature. This unusual result can be explained by the evolution of the material thermo‐optic coefficient, dn/dT. Indeed, the higher the conversion, the lower this coefficient.

Plasmonic color filtering has provided a range of new techniques for "printing" images at resolutions beyond the diffraction-limit, significantly improving upon what can be achieved using traditional, dye-based filtering methods. Here, a new approach to high-density data encoding is demonstrated using full color, dual-state plasmonic nanopixels, doubling the amount of information that can be stored in a unit-area. This technique is used to encode two data sets into a single set of pixels for the first time, generating vivid, near-full sRGB (standard Red Green Blue color space)color images and codes with polarization-switchable information states. Using a standard optical microscope, the smallest "unit" that can be read relates to 2 × 2 nanopixels (370 nm × 370 nm). As a result, dual-state nanopixels may prove significant for long-term, high-resolution optical image encoding, and counterfeit-prevention measures. over their microscale, dye-based counterparts. Chief among these are their subwavelength dimensions (leading to ultradense, ultrathin pixel arrays), and their long-term environmental stability (they do not degrade or fade over time due to radiation exposure). As a result, plasmonic filters have been positioned as new technological solutions for subwavelength color printing, [1,4,[7][8][9]12] anticounterfeiting measures, [19,20] and RGB splitting for image sensors; [2,17,21,22] thus representing one of the most promising, technologically relevant areas of current plasmonic research activity. Here, we explore a new application of polarizationcontrolled plasmonic filters: dual output, full-color optical image encoding. Recent developments in the engineering and manipulation of materials on the nanoscale have given rise to a number of new techniques with the potential for physically encoding data and images into optically readable volumes and surfaces. [23,24] Using semiconductor quantum dots, [25][26][27] graphene, [28] and various super-resolution lithography techniques, [29][30][31][32][33][34] researchers are demonstrating novel 2D and 3D techniques that may enable the next generation of optical storage and encoding technologies. Plasmonic particles and filters have also seen applications in these research areas, with the aforementioned image encoding examples having been joined by demonstrations of their use in optical data storage. [23,24,[35][36][37] Here, we show a new utilization of image encoding using polarization multiplexed plasmonic filters, where, unlike previous studies that employed color or position switching in fixed images, [14,38] we show that two arbitrary, full-color images can be encoded into a single array of pixels. Our individual pixels are comprised of asymmetric cross-shaped nanoapertures in a thin film of aluminum. Each aperture is engineered to exhibit two independent plasmonic resonances which can be tuned across the sRGB (standard Red Green Blue) color-space (a single pixel can be encoded with any two arbitrary colors). We go on to show that by using the smallest visible unit ...
