A 1:12 phosphomolybdic anion film modified carbon paste electrode (PMo(12) electrode) is prepared by electrochemical deposition and its application is studied by cyclic voltammetry. The film modified electrode can adsorb PMo(12) selectively and thus be used for the determination of trace phosphorus. In a solution containing 2 mug ml(-1) phosphorus, the relative standard deviation is 4.69% (n=4), the peak height also varies linearly with the concentration of phosphorus over the range 0.4-25 mug ml(-1), and the detection limit is 0.04 mug ml(-1). The method is convenient and rapid. It has been used for the determination of inorganic phosphorus in phytic acid directly with satisfactory results.

Background: Polyether ether ketone (PEEK) was modified by a sulfuric and nitric acid mixed system to improve the solubility of the material and the gas selective permeability of the film. SN1 and SN5, synthesized from mixed acid systems (with ratios of nitric acid and sulfuric acid of 1:1 and 1:5, respectively) were chosen because they had comparable nitro groups but differing sulfonyl groups. To investigate the impact of the type and content of sulfonated and nitrated polyether ether ketone (SNPEEK) on the structure and physicochemical properties of the films, SN1/polyvinyl chloride (PVC) and SN5/polyvinyl chloride films were made by adding varying amounts of SN1 and SN5 (0.

Well-designed artificial scaffolds are urgently needed due to the limited self-repair capacity of bone, which hampers effective regeneration in critical defects. Optimal scaffolds must provide physical guidance to recruit cells and immune regulation to improve the regenerative microenvironment. This study presents a novel scaffold composed of dual-sided centripetal microgrooved poly(D,L-lactide-co-caprolactone) (PLCL) film combined with a dynamic hydrogel containing prednisolone (PLS)-loaded Prussian blue nanoparticles (PB@PLS).

Polymers have been ruling the packaging industry for decades due to their versatility, easy manufacturability, and low cost. The overuse of non-biodegradable plastics in food packaging has become a serious environmental concern. Multi-walled carbon nanotube (MWCNT) reinforced nanocomposites have exceptional electrical, thermal, and mechanical properties.

Formamidinium lead triiodide (FAPbI) has received significant attention in the field of perovskite solar cells (PSCs) owing to its excellent optoelectronic properties and high thermal stability. However, the photoactive α-FAPbI perovskites are highly susceptible to degradation into non-perovskite δ-FAPbI phases, especially under humid conditions, which severely diminishes the device performance of FAPbI PSCs. Here, we propose an interfacial seeding strategy for regulating crystallization and stabilizing α-FAPbI perovskites in humid air.

The insufficient density and discontinuity of solar energy of photothermal superhydrophobic flexible film seriously affect the practical application. Light energy harvesting and heat energy storage are effective ways to solve this problem. Inspired by the viscous temperature-regulating material within the inflorescence of Lobelia telekii and the arrangement of bracts on its surface, a flexible film for photoheat storage is proposed that integrated a three-order photoheat trap and one-order heat storage.
