Nanotubular highways for intercellular organelle transport
2004年2月13日 · Here, we describe highly sensitive nanotubular structures formed de novo between cells that create complex networks. These structures facilitate the selective transfer of membrane vesicles and organelles but seem to impede the flow of small molecules.
Isoreticular Covalent Organic Pillars: Engineered Nanotubular …
2024年7月20日 · In our ongoing pursuit, we have successfully engineered a novel class of single-molecule nanotubes─isoreticular covalent organic pillars (iCOPs)─by stacking formylated macrocycles through multiple dynamic covalent imine bonds, guided by …
Membrane nanotubes are ancient machinery for cell-to-cell …
Nanotubular connections between mammalian cell types came into the focus only two decades ago, when “live cell super-resolution imaging” was introduced. Observations of these long-time overlooked structures led to understanding mechanisms of their growth/withdrawal and exploring some key genetic and signaling factors behind their formation.
Construction of dendritic Pt–Pd bimetallic nanotubular …
2024年8月23日 · Herein, we report a novel design of one-dimensional (1D) Pt–Pd dendritic nanotubular heterostructures (DTHs) by controlling the degree of Pt 2+-Pt reduction reaction and Pd-Pt galvanic replacement reaction with uniform Pd nanowires as sacrificial templates. The obtained Pt–Pd bimetallic DTHs catalyst exhibited uniform and dense Pt dendritic ...

2012年7月17日 · Here we report a strategy for enforcing the nanotubular assembly of rigid macrocycles in both the solid state and solution based on the interplay of multiple hydrogen-bonding and aromatic π−π ...
Here, we describe highly sensitive nanotubular structures formed de novo between cells that create complex networks. These structures facilitate the selective transfer of membrane ves-icles and organelles but seem to impede the flow of small molecules.
Bottom-up realization of a porous metal–organic nanotubular …
2011年2月27日 · Here, we demonstrate a bottom-up approach for the fabrication of well-defined nanotubes with high tunability using metal ions and organic molecules as building blocks. We succeeded in rationally ...
Nanotubular metal–insulator–metal capacitor arrays for ... - Nature
2009年3月15日 · Iron oxides nanobelt arrays rooted in nanoporous surface of carbon tube textile as stretchable and robust electrodes for flexible supercapacitors with ultrahigh areal energy density and remarkable...
Fabrication of Chiral‐Selective Nanotubular Heterojunctions …
2016年6月29日 · Novel, chiral-selective linear nanotubular heterojunctions were achieved by living supramolecular polymerization of perylenediimide (PDI) derivatives. We demonstrate that the chiral seed can effectively bias achiral PDI molecules to polymerize on its …
Progress in supercapacitors: roles of two dimensional nanotubular ...
Due to their unique hierarchical architecture, excellent electrical and mechanical properties, and high specific surface area, nanotubular networks have been widely investigated as efficient electrode materials in supercapacitors, while maintaining their inherent characteristics of high power and long cycling life.
