ChemFoodChem, EarlyView.Agro‐industrial residues contain dietary fiber and phenolics, but coexistence alone does not establish a phenolic‐bound ingredient. Processing‐dependent identity is verified through fraction‐specific analysis and common‐basis mass balance. Food‐grade translation requires final‐product performance, sensory acceptance, safety, and claim‐matched ...

Chemistry – A European Journal, EarlyView.Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Relationship between inferred penetration depth and the hydrophobicity (log Kow) of the PAHs.
, 2013 Kow = Concentration in octanol phase/Concentration in aqueous phase. The Kow values for the PAHs were retrieved from http://www.env.gov.bc.ca/wat/wq/BCguidelines/pahs/pahs-01.htm.

Illuminating Olympicenes: Insights Into Anti‐Kasha Photophysics in Polycyclic Aromatic Hydrocarbons
Chemistry – A European Journal, EarlyView.Compact olympicene‐based chromophores reveal unexpectedly rich excited‐state behavior, including dual fluorescence, excitation‐dependent emission, and anti‐Kasha‐type emission. Tunable locally excited and intramolecular charge‐transfer states emerge from subtle structural changes, expanding the design rules for polycyclic aromatic chromophores and ...

Study on the sorption/desorption of PAHs and effects of MWCNTs on distribution of PAHs in mangrove sediment aggregates [PDF]
, 2014 红树林是热带、亚热带河口潮间带重要的生态系统。沿岸人类活动加剧，使PAHs大量进入红树林生态系统。红树林沉积物作为该生态系统中PAHs最重要的赋存场所，PAHs在其中的迁移、转化过程引起广泛的关注。吸附/解吸作为PAHs迁移、转化过程中的重要环节，控制生物富集、生物降解等诸多过程。目前实验室中考察吸附/解吸行为多以分散颗粒物为研究对象，然而现实环境中红树林沉积物以团聚体的形式存在，以沉积物团聚体为研究对象，考察PAHs的吸附/解吸行为具有重要的理论和实际意义。 第一部分绪论 ...

Chemistry – A European Journal, EarlyView.Regioisomerism rewires orbital topology and electronic polarity in curved non‐alternant π‐systems, switching both optical response and alkali metal ion recognition from Na+ to Rb+ selectivity. ABSTRACT Herein, we explore the fundamental concept of combining the molecular curvature of a molecular fragment of buckminsterfullerene with the pronounced ...
