Abstract The issue of plastic pollution has attracted widespread social attention. Gelatin is valued as a degradable bio-based
material, especially as an edible active packaging material. However, the commonly used solution-casting filmforming technology limits the mass production of gelatin films. In order to improve the production efficiency
and enhance the commercial value of gelatin films, in this study, fish gelatin (FG) particles were successfully
blended with essential oils (EOs) to prepare active films by melt extrusion technique, a common method for commercial plastics, and applied to bread preservation. FG and EOs showed good compatibility with each other. The

Abstract The development and utilization of biomass and agroforestry processing byproducts for high-value applications
have been an important topic in the field of renewable materials research. Based on this, a two-step microwave
hydrothermal pre-carbonization and KOH activation method was proposed to synthesize tannin-based activated
carbons with a high specific surface area, hierarchical pore structure, and good electrochemical performance. The
microstructure, texture properties, and physicochemical characteristics were investigated. The results show that
the prepared tannin-based activated carbons presented a hierarchical pore structure (micro- and mesopores) with
a specific surface area as high as 997.46 m3 g−1

Abstract Melamine-dialdehyde starch resins used for wood surface finishes have been developed. The reaction of melamine
with dialdehyde starch has been shown to occur by FTIR and MALDI ToF spectrometry, with several oligomer
species due to the reaction of the two materials being identified, and the resin thermal stability was studied by
thermogravimetric analysis. The resins were prepared by two different procedures when it was realized that dialdehyde starch is sensitive to too high a temperature for prolonged times. The melamine-dialdehyde starch resins
were applied on particleboard supports as a direct liquid surface finish and a resin-impregnated paper. The surface finishes… More >

Abstract All-inorganic CsPbI3 perovskite has attracted wide attention due to its desirable optical bandgap (Eg: ∼1.7 eV) as
well as high chemical stability. Nevertheless, the photovoltaic performance of CsPbI3 perovskite solar cells (PSCs)
was limited by severe nonradiative charge recombination due to high defect density at the grain boundary and
surface of perovskite films. To address this issue, a pyrrolidinium iodide (PyI) molecule was introduced to modify
the surface and grain boundary of CsPbI3 perovskite films to passivate defects, which improves the quality of
CsPbI3 perovskite films as well as induces the generation of a quasi-2D Py2CsPb2I7 capping layer between perovskite… More >

and antioxidant properties. Compared with pure tung oil, the lubricating and antioxidant performance of tung
oil is significantly improved after adding additives. Adding the 1.0 wt% additive to the tung oil reduced the friction wear coefficient and the volume, and the… More >

Abstract Three-dimensional C/SiOx nanofiber anode was prepared by polydimethylsiloxane (PDMS) and polyacrylonitrile

In contrast to conventional carbon covering Si-based anode materials, the C/SiOx structure is made up of PAN-C, a 3D carbon substance, and SiOx loading steadily on PAN-C. The PAN carbon nanofibers and loaded SiOx from pyrolyzed PDMS give increased
