“…After the DES system is formed, an obvious shift in the O–H infrared spectrum occurs due to the influence of hydrogen-bonding interactions. 44,45 Additionally, the impact of hydrogen-bonding interactions on the system can be observed in the 1 H NMR spectrum shown in Fig. 1c and d.…”

“…In FeCl 3 ·6H 2 O, the hydroxyl group interacts with chlorine in the vibrational mode of O–H···Cl, and the absorption peak appears near 3442 cm –1 . After the formation of the solution, the chlorine in FeCl 3 ·6H 2 O interacts with the hydroxyl group of urea to form a new vibrational mode O–H···Cl, which shifted the absorption peak by 8 cm –1 . As a result, the above peak shifts to a lower wavenumber.…”

“…In addition, IR spectroscopy was used to confirm the interaction among the components of DES (Figure 1b). In 36 As a result, the above peak shifts to a lower wavenumber. Similarly, in pure urea, the absorption peak at 1400−1700 cm −1 is a stretching vibration peak of N−H, which changes significantly after the formation of DES, due to the coordination of N−H with Cl or H 2 O in metal chlorides.…”

The epitaxial organization of nano-objects with different compositions and structures into superlattice nanorods holds great promise for photocatalytic biomass oxidation as it can make full use of sunlight and improve carrier transport efficiency. Here, we construct type II photocatalytic heterojunctions using α-Fe 2 O 3 and Nb 2 O 5 , both of which are alternately grown in situ to form superlattice nanorod structures. Due to the interlaced growth of thin layers of α-Fe 2 O 3 and Nb 2 O 5 , the phase interface between α-Fe 2 O 3 and Nb 2 O 5 is greatly increased, which effectively improves the catalytic activity of the catalyst. The selective oxidation of HMF was achieved by superlattice α-Fe 2 O 3 /Nb 2 O 5 /C nanorod photoelectrocatalysts with 96.6% FDCA selectivity, which was 2.3 times higher than that of α-Fe 2 O 3 and 3.5 times higher than that of Nb 2 O 5 , respectively, and the conversion of HMF was close to 100%. This work provides a new idea for the design of catalysts with superlattice structure and used for biomass conversion.

“…Magnetic nanoparticles are 10–100 nanoparticles represented by iron, cobalt, nickel or metal oxides with inherent magnetic properties are the main source of magnetically responsive targeted drug delivery systems ( Shi et al, 2022 ). Superparamagnetic magnetic hematite (γ-Fe2O3) or magnetite (Fe 3 O 4 ) are commonly used magnetic nanoparticles in magnetically responsive drug smart response elements.…”

Topical drug delivery is widely used in various diseases because of the advantages of not passing through the gastrointestinal tract, avoiding gastrointestinal irritation and hepatic first-pass effect, and reaching the lesion directly to reduce unnecessary adverse reactions. The skin helps the organism to defend itself against a huge majority of external aggressions and is one of the most important lines of defense of the body. However, the skin’s strong barrier ability is also a huge obstacle to the effectiveness of topical medications. Allowing the bioactive, composition in a drug to pass through the stratum corneum barrier as needed to reach the target site is the most essential need for the bioactive, composition to exert its therapeutic effect. The state of the skin barrier, the choice of delivery system for the bioactive, composition, and individualized disease detection and dosing planning influence the effectiveness of topical medications. Nowadays, enhancing transdermal absorption of topically applied drugs is the hottest research area. However, enhancing transdermal absorption of drugs is not the first choice to improve the effectiveness of all drugs. Excessive transdermal absorption enhances topical drug accumulation at non-target sites and the occurrence of adverse reactions. This paper introduces topical drug delivery strategies to improve drug effectiveness from three perspectives: skin barrier, drug delivery system and individualized drug delivery, describes the current status and shortcomings of topical drug research, and provides new directions and ideas for topical drug research.
