Veterinary antibiotics can be released to environment by the animals' excretions, which thereby poses human health and ecological risks. Six (tetracycline, oxytetracycline, chlortetracycline, sulfamethazine, sulfamethoxazole, sulfadimethoxine) at three concentrations (5, 10, 20 mg kg–1 soil) were employed in pots filled with a loamy sand upland soil. Three types of vegetable seedlings, including cucumber (Cucumis sativus), cherry tomato (Solanum lycopersicum), lettuce (Lactuca sativa), also...
We report protoporphyrin IX (PpIX) encapsulated pH-responsive micelles for cancer treatment. This system showed micellization/demicellization transition at tumoral acidic pH and enabled in vivo tumor diagnosis therapy simultaneously.
The nanoscale interactions of room temperature ionic liquids (RTILs) at uncharged (graphene) and charged (muscovite mica) solid surfaces were evaluated with high resolution X-ray interface scattering fully atomistic molecular dynamics simulations. At graphene surfaces, the imidazolium-based RTIL ([bmim(+)][Tf(2)N(-)]) exhibits a mixed cation/anion layering strong interfacial densification first layer. layer density observed via experiment is larger than that predicted by simulation apparent...
The screening of surface charge by dissolved ions at solid–liquid interfaces—in the region interfacial fluid known as electrical double layer (EDL)—plays a recurrent role in science, from ion adsorption to colloidal mechanics transport properties nanoporous media. A persistent unknown theories EDL-related phenomena is structure Stern layer, near-surface portion EDL where water molecules and adsorbed form specific short-range interactions with atoms. Here, we describe set synchrotron X-ray...
Charged materials in aqueous systems interact according to their interfacial properties, typically described by the electrical double layer (EDL). Distributions of divalent metal cations at muscovite (001)-solution interface observed using resonant anomalous X-ray reflectivity demonstrate an unexpected complexity with respect EDL structure. Three forms adsorbed can coexist: classical inner-sphere and outer-sphere complexes a third "extended" complex located farther from surface. Their...
The interfacial structure between the muscovite (001) surface and aqueous solutions containing monovalent cations (3 × 10(-3) m Li(+), Na(+), H(3)O(+), K(+), Rb(+), or Cs(+), 3 10(-2) Li(+) Na(+)) was measured using in situ specular X-ray reflectivity. element-specific distribution of Rb(+) also obtained with resonant anomalous results demonstrate complex interdependencies among adsorbed cation coverage speciation, hydration structure, relaxation. Electron-density profiles solution near...
