A self-complexing and self-assembling pillar[5]arene

Nathan L. Strutt、Huacheng Zhang、Marc A. Giesener 等 5 位作者2011-12-21Chemical Communications

A monofunctionalised pillar[5]arene derivative carrying a viologen side chain which exhibits self-complexation in dilute dichloromethane solutions forms supramolecular daisy chain polymers and eventually organogels as its concentration is increased three-fold over the range from 0.1 to 100 mM.

Flexible and Iridescent Chiral Nematic Mesoporous Organosilica Films

Kevin E. Shopsowitz、Wadood Y. Hamad、Mark J. MacLachlan2011-12-21Journal of the American Chemical Society

Nanocrystalline cellulose (NCC) has been used to template ethylene-bridged mesoporous organosilica films with long-range chirality and photonic properties. The structural color of the organosilica films results from their chiral nematic ordering, can be varied across the entire visible spectrum, and responds to the pr…

Atomic Oxygen Effects on POSS Polyimides in Low Earth Orbit

Timothy K. Minton、Michael Wright、Sandra J. Tomczak 等 11 位作者2011-12-21ACS Applied Materials & Interfaces

Kapton polyimde is extensively used in solar arrays, spacecraft thermal blankets, and space inflatable structures. Upon exposure to atomic oxygen in low Earth orbit (LEO), Kapton is severely eroded. An effective approach to prevent this erosion is to incorporate polyhedral oligomeric silsesquioxane (POSS) into the pol…

Organometallic Cages as Vehicles for Intracellular Release of Photosensitizers

Frédéric Schmitt、Julien Freudenreich、Nicolas P. E. Barry 等 6 位作者2011-12-21Journal of the American Chemical Society

Water-soluble metalla-cages were used to deliver hydrophobic porphin molecules to cancer cells. After internalization, the photosensitizer was photoactivated, significantly increasing the cytotoxicity in cells. During the transport, the photosensitizer remains nonreactive to light, offering a new strategy to tackle ov…

Easy Synthesis and Imaging Applications of Cross-Linked Green Fluorescent Hollow Carbon Nanoparticles

Youxing Fang、Shaojun Guo、Dan Li 等 7 位作者2011-12-21ACS Nano

We propose an ingenious method for synthesizing cross-linked hollow fluorescent carbon nanoparticles (HFCNs) with green emission by simply mixing acetic acid, water, and diphosphorus pentoxide. This is an automatic method without external heat treatment to rapidly produce large quantities of HFCNs, in contrast to othe…

Analyse d'un processus pédogénétique par une approche expérimentale : le lessivage des argiles dans le sol

Laurence Quénard2011-12-20OpenAlex

Le lessivage, compris comme la translocation de particules fines dans les sols à partir d’un horizon dit éluvié vers un horizon d’accumulation dit illuvié, est considéré comme un processus pedogénétique majeur. Il a été décrit dans de nombreux sols mais reste assez peu connu, mal caractérisé et son existence même est…
