Elasticity, an often-overseen parameter in the development of nanoscale drug delivery systems
Beilstein J. Nanotechnol. 2023, 14, 1149–1156, doi:10.3762/bjnano.14.95
- -mediated uptake mechanisms, whereas hard NLGs are predominantly internalized via the clathrin-mediated pathway [32]. Another example of the enhanced tumor accumulation of softer nanoparticles is presented by Tao et al. Even though the hyaluronic-acid-modified mesoporous organosilica nanoparticles (MMONs
The role of sulfonate groups and hydrogen bonding in the proton conductivity of two coordination networks
Beilstein J. Nanotechnol. 2022, 13, 437–443, doi:10.3762/bjnano.13.36
- materials are currently being discussed as potential alternatives. These include coordination polymers (CPs), covalent organic frameworks (COFs), polyoxometalates (POMs), hydrogen-bonded organic frameworks (HOFs), and mesoporous organosilica materials (MPOs) [3][9][10][11]. In particular, proton-conducting
pH-mediated control over the mesostructure of ordered mesoporous materials templated by polyion complex micelles
Beilstein J. Nanotechnol. 2019, 10, 144–156, doi:10.3762/bjnano.10.14
- , we have been developing an original route for the synthesis of ordered mesoporous materials based on the use of non-conventional structure-directing agents. Ordered mesoporous silica and organosilica materials were prepared under mild acidic conditions by using polyion complex (PIC) micelles as
First examples of organosilica-based ionogels: synthesis and electrochemical behavior
Beilstein J. Nanotechnol. 2017, 8, 736–751, doi:10.3762/bjnano.8.77
- transport. A new preparation process using an organic linker, bis(3-(trimethoxysilyl)propyl)amine (BTMSPA), yields stable organosilica matrix materials. The second ionogel component, the ionic liquid 1-methyl-3-(4-sulfobutyl)imidazolium 4-methylbenzenesulfonate, [BmimSO3H][PTS], can easily be prepared with
- near-quantitative yields. [BmimSO3H][PTS] is the proton conducting species in the ionogel. By combining the stable organosilica matrix with the sulfonated ionic liquid, mechanically stable, and highly conductive ionogels with application potential in sensors or fuel cells can be prepared. Keywords
- : ionic liquids; ionogels; organosilica; proton conductivity; Introduction Ionic liquids (ILs), that is, substances solely composed of ionic species have been studied for virtually every application from organic synthesis to lubrication and battery technology [1][2][3][4]. A particularly promising field
Controlled synthesis and tunable properties of ultrathin silica nanotubes through spontaneous polycondensation on polyamine fibrils
Beilstein J. Nanotechnol. 2013, 4, 793–804, doi:10.3762/bjnano.4.90
- reports on the carbonization of porous silica–polymer [47] and organosilica/surfactant composites [48][49]. However, the synthesis of silica–carbon composite nanotube materials is still very rare. Liu and co-workers [50] have recently reported the fabrication of silica–carbon nanotubes by carbonization of
- organosilica nanotubes, which were synthesized by using expensive ethylene- or phenylene-bridged alkoxysilanes through the soft-template assembly method mediated by commercially available P123 in dilute solution. We found that the direct carbonization of synthesized LPEI@silica hybrid nanotubes under N2
Distribution of functional groups in periodic mesoporous organosilica materials studied by small-angle neutron scattering with in situ adsorption of nitrogen
Beilstein J. Nanotechnol. 2012, 3, 428–437, doi:10.3762/bjnano.3.49
- easily identify functional groups but is limited in its ability to analyze the local distribution of them. Combined techniques help to overcome these limits. Morell et al. studied the formation process of a mesoscopically ordered biphenylene-bridged organosilica with crystal-like pore walls by in situ
