Article Abstract
The covalent functionalization of synthetic peptides allows the modification of different biomaterials (metallic, polymeric, and ceramic), which are enriched with biologically active sequences to guide cell behavior. Recently, this strategy has also been applied to decellularized biological matrices. In this study, the covalent anchorage of a synthetic peptide (REDV) to a pericardial matrix decellularized via Schiff base is realized starting from concentrated peptide solutions (10 M and 10 M). The use of a labeled peptide demonstrated that as the concentration of the working solution increased, the surface density of the anchored peptide increased as well. These data are essential to pinpointing the concentration window in which the peptide promotes the desired cellular activity. The matrices were extensively characterized by Water Contact Angle (WCA) analysis, Differential Scanning Calorimetry (DSC) analysis, geometric feature evaluation, biomechanical tests, and preliminary in vitro bioassays.

Carbonized wood has great potential as a self-supported electrode for energy storage/conversion applications. However, developing efficient and economical bifunctional electrodes by customizing the surface structure remains a challenge. This study proposes a novel multifunctional electrode design strategy, using N/P co-doped carbonized wood (NPCW) as carriers and in situ grows copper nanoparticles (Cu NPs) as nucleation centers to induce vertical growth of CuCo-layered double hydroxid (LDH) nanosheets along the substrate.

Achieving a crack-free, high-surface-area photoanode is essential for maximizing the efficiency of dye-sensitized solar cells (DSSCs). In this work, rutile titanium dioxide (rTiO) nanoflowers were synthesized hydrothermally and then conformally coated with copper(I) oxide (CuO) by RF magnetron sputtering to seal pre-existing cracks and to create a nanothorn surface favorable for dye adsorption. Systematic control of the sputtering time identified 60 min as optimal condition, yielding a photoanode thickness of about 6.

In the stable cone-jet regime, liquid usually presents the shape of a cone extended by a jet at its apex, with jet breakup yielding fine drops. The dynamics of the Taylor cone critically affect the stability of the jet and further determine the jet and/or drop size. In the present work, the morphology of the Taylor cone, cone length, and cone angle were studied through experimental and numerical means, where the operating parameters and liquid properties are considered.

Lithium metal batteries (LMBs) offer exceptional energy density and output voltage. However, their practical application remains hindered by sluggish ion transport and uncontrolled lithium dendrite formation, particularly under fast-charging conditions. Here, we report a facet-engineered anion-regulating separator based on zeolitic imidazolate framework-8 (ZIF-8) with preferentially crystal-exposed (110) facets.

Developing solid electrolytes with high ionic conductivity, a high voltage window, low flammability, and excellent interface compatibilities with both the anode and cathode for lithium-metal batteries is still a great challenge but highly desirable. Herein, we achieve this target through an in situ copolymerization of vinyl ethylene carbonate (VEC) together with acrylonitrile (AN) under fitting ratios inside a porous polyacrylonitrile (PAN) fiber membrane doped with flame-retardant decabromodiphenyl ethane (DBDPE) molecules. The received fiber-reinforced polycarbonate-based composite electrolyte with an ultrathin thickness of 13 μm exhibits good internal interfacial compatibility because of the same AN structure and superior flame-retardant performance due to the doped DBDPE molecules.
