The drastic temperature variation has almost no influence on the diffusion and transfer rate of electrolyte ions, further evidencing the advanced feature of the hierarchical pore structure. Additionally, HPC//Li4Ti5O12 LIC assembled with the Li-based electrolyte also presents a superior Ragone performance. The coexistence of micro- and mesopores for the HPC makes it an attractive electrode material for various capacitive-energy-storage devices. This work provides a promising way to realize the plasticity of pore channels and mass production of high capacitive storage ability of electrode material via the combination of template-directing and chemical activation strategies.The development and application of natural antibacterial materials have always been the focus of biomedical research. Borneol as a natural antibacterial compound has received extensive attention. However, the hydrophobicity caused by its unique structure limits its application range to a certain extent. In this study, we combine zwitterionic 2-methacryloyloxyethyl phosphorylcholine (MPC) with a complex bicyclic monoterpene structure borneol compound and prepare an excellent antifouling and antibacterial surface via the Schiff-base bond. The prepared coating has excellent hydrophilicity verified by the contact angle (CA), and its polymer layer is confirmed by X-ray photoelectron spectroscopy (XPS). The zwitterion MPC and borneol moieties in the copolymer play a coordinating role, relying on super hydration and the special stereochemical structure to prevent protein adsorption and inhibit bacterial adhesion, respectively, which are demonstrated by bovine serum albumin (BSA) adsorption and antibacterial activity test. Moreover, the water-soluble borneol derivative as the antibacterial surfaces we designed here was biocompatible toward MRC-5 (lung fibroblasts), as showed by in vitro cytotoxicity assays. Such results indicate the potential application of the as-prepared hydrophilic surfaces in the biomedical materials.The control over the amount of psychoactive THC (Δ-9-tetrahydrocannabinol) in commercial cannabidiol (CBD) products has to be strict. A fast and simple semiquantitative Ag(I)-impregnated paper spray mass spectrometric method for differentiating between THC and CBD, which show no difference in standard single-stage or tandem MS, was established. Because of a different binding affinity to Ag(I) ions, quasi-molecular Ag(I) adducts [THC + Ag]+ and [CBD + Ag]+ at m/z 421 and 423 give different fragmentation patterns. The product ions at m/z 313 for THC and m/z 353 and 355 for CBD can be used to distinguish THC and CBD and to determine their ratio. Quantification of THC/CBD ratios in commercial CBD oils was accomplished with a low matrix effect (-2.2 ± 0.4% for THC and -2.0 ± 0.3% for CBD). After simple methanol extraction (recovery of 87.3 ± 1.2% for THC and 92.3 ± 1.4% for CBD), Ag(I)-impregnated paper spray analysis was employed to determine this ratio. A single run can be completed in a few minutes. This method was benchmarked against the UHPLC-UV method. Ag(I)-impregnated paper spray MS had the same working range (THC/CBD = 0.001-1) as UHPLC-UV analysis (R2 = 0.9896 and R2 = 0.9998, respectively), as well as comparable accuracy (-2.7 to 14%) and precision (RSD 1.7-11%). The method was further validated by the analysis of 10 commercial oils by Ag(I)-impregnated paper spray MS and UHPLC-UV analysis. Based on the determined relative concentration ratios of THC/CBD and the declared CBD concentration, 6 out of 10 CBD oils appear to contain more THC than the Dutch legal limit of 0.05%.Molecular organization plays an essential role in organic semiconductors since it determines the extent of intermolecular interactions that govern the charge transport present in all electronic applications. The benefits of hydrogen bond-directed self-assembly on charge transport properties are demonstrated by comparing two analogous pyrrole-based, fused heptacyclic molecules. The rationally designed synthesis of these materials allows for inducing or preventing hydrogen bonding. Strategically located hydrogen bond donor and acceptor sites control the solid-state arrangement, favoring the supramolecular expansion of the π-conjugated surface and the subsequent π-stacking as proved by X-ray diffraction and computational calculations. The consistency observed for the performance of organic field-effect transistors and the morphology of the organic thin films corroborate that higher stability and thermal robustness are achieved in the hydrogen-bonded material.UV254 disinfection strategies are commonly applied to inactivate pathogenic viruses in water, food, air, and on surfaces. There is a need for methods that rapidly predict the kinetics of virus inactivation by UV254, particularly for emerging and difficult-to-culture viruses. We conducted a systematic literature review of inactivation rate constants for a wide range of viruses. Using these data and virus characteristics, we developed and evaluated linear and nonlinear models for predicting inactivation rate constants. Multiple linear regressions performed best for predicting the inactivation kinetics of (+) ssRNA and dsDNA viruses, with cross-validated root mean squared relative prediction errors similar to those associated with experimental rate constants. We tested the models by predicting and measuring inactivation rate constants of a (+) ssRNA mouse coronavirus and a dsDNA marine bacteriophage; the predicted rate constants were within 7% and 71% of the experimental rate constants, respectively, indicating that the prediction was more accurate for the (+) ssRNA virus than the dsDNA virus. Finally, we applied our models to predict the UV254 rate constants of several viruses for which high-quality UV254 inactivation data are not available. Our models will be valuable for predicting inactivation kinetics of emerging or difficult-to-culture viruses.Combinatorial and high-throughput experimentation (HTE) is achieving more relevance in material design, representing a turning point in the process of accelerated discovery, development, and optimization of materials based on data-driven approaches. The versatility of drop-on-demand inkjet printing (IJP) allows performing combinatorial studies through fabrication of compositionally graded materials with high spatial precision, here by mixing superconducting REBCO precursor solutions with different rare earth (RE) elements. The homogeneity of combinatorial Y1-xGd x Ba2Cu3O7 samples was designed with computational methods and confirmed by energy-dispersive X-ray spectroscopy (EDX) and high-resolution X-ray diffraction (XRD). AZD1656 Carbohydrate Metabolism activator We reveal the advantages of this strategy in the optimization of the epitaxial growth of high-temperature REBCO superconducting films using the novel transient liquid-assisted growth method (TLAG). Advanced characterization methods, such as in situ synchrotron growth experiments, are tailored to suit the combinatorial approach and demonstrated to be essential for HTE schemes.
