Electrochemical oxidation of biomass-derived 5-hydroxymethylfurfural (HMF) offers a sustainable route to produce value-added chemicals, yet its efficiency is often limited by sluggish charge transfer and interfacial reaction kinetics. In this work, a CeO₂/β-Ni(OH)₂ heterojunction electrode was constructed via an in situ electrodeposition strategy. The built-in electric field formed at the heterointerface promotes directional charge transfer and accelerates the formation of active NiOOH species, while the introduction of CeO₂ significantly enhances surface hydrophilicity and substrate affinity. The synergistic regulation of interfacial electric field and wettability enables efficient electron–proton transfer, resulting in markedly improved HMF electrooxidation performance. This study highlights an effective interface-engineering strategy for boosting biomass electrocatalysis.

There is a growing demand for high-performance THz shielding and absorbing materials to prevent electromagnetic interference (EMI) or pollution. Inspired by staggered cellular structures, a bioinspired strategy was proposed to fabricate multilayer-MXene (m-Ti₃C₂T_x)/cellulose nanofibrils (CNFs) aerogel frameworks with staggered stacking architectures via direct ink writing (DIW) 3D printing technology for enhanced THz shielding and absorption performance. The framework exhibits an excellent maximum reflection loss (RL) of 54.01 dB in the 0.5-3.0 THz range (100% qualified bandwidth) and a high absorption of 99.40%. It realizes a high green shielding index (g_s), the range of g_s > 9 that meets the standard for excellent green EMI shielding up to 2.5 THz. Meanwhile, it demonstrates high shielding effectiveness (SE) exceeding 40 dB across a broad gigahertz (GHz) frequency range from 3.9 to 18 GHz, particularly reaching an excellent 101.84 dB in the Ku band. This bionic strategy of staggered structures achieved via 3D printing technology demonstrates significant potential for fabricating high-design-freedom shielding components with excellent THz shielding and absorption properties.

In the paper published on Science of Traditional Chinese Medicine (STCM), the authors employed UPLC-MS/MS technology and elucidated the processing principle of rhubarb pieces based on in vivo profile of components. This study comprehensively analyzed the dynamic in vivo changes of prototype anthraquinones and their glucuronide metabolites in rhubarb from the perspectives of absorption, distribution, and excretion. It proposed that processing can reduce the exposure of components, achieve targeted distribution in the intestine, and accelerate the excretion of components, thereby clarifying the processing mechanism of 'raw rhubarb purges while steamed rhubarb moderates'. This provides a solid research perspective for the study of the processing principles of traditional Chinese medicine.
