“…22 Recently, the deposition of silica on the surface of TMV and an E50Q mutant of TMV was also achieved at a higher pH (>7). 35 In both studies, the length of composite fibre was determined by the original template, although some longer fibres were observed. We hypothesize that, under weak acidic conditions, TEOS can accumulate on the surface of TMV due to the non-covalent interactions between TMV and TEOS while the TMV head-to-tail assembly is favored (Scheme 1, pathway A).…”

Inorganic-polymer hybrid nanofibres were prepared by using a rod-like tobacco mosaic virus (TMV) as a template. With tetraethylorthosilicate (TEOS) as a precursor, long silica-coated TMV fibres were formed via a head-to-tail assembly, which showed a substantial increase of the elastic modulus. Furthermore, homogenous titania-TMV hybrid fibres could be prepared using polyaniline-coated TMV fibres as a template, which were used to form a composite film that was able to sense liquefied petroleum gases.

“…In a colloidal system with monovalent (1:1) electrolytes, the P-B equation is expressed as follows; (3) where, F a is faraday constant, is bulk ion concentration in mole/L, is vacuum permittivity, and is relative permittivity of suspending medium. 18 By applying Derjaguin approximation, the P-B equation can be simply expressed in the rectangular coordinates present in equation (4). (4) Above P-B equation can be expressed in the dimensionless form by introducing dimensionless parameters that are defined as ,…”

“…Though many anisotropic particles suspending in an aqueous medium such as synthetic nanorod 1,2 and natural biomolecular suspensions 3,4 have been exploited for the engineering and medical applications, the analysis on the colloidal interaction between these particles has not fully understood yet. There are several difficulties in analyzing the electrostatic interaction of anisotropic particles; firstly, the electrostatic interaction is dependent to the configuration because of the anisotropic structure of interacting particles.…”

The electrical repulsive energy between two model cylinders was calculated by solving nonlinear PoissionBoltzmann (P-B) equation under Derjaguin approximation. Effects of the surface potential, Debye screening length, and configuration of cylinders on the repulsive interaction energy were examined. Due to the anisotropy of the shape of cylinder, the interaction repulsive energy showed dependence to the configuration of particles; cylinders aligned in end-to-end configuration showed largest repulsive energy and crossed particles had lowest interaction energy. The configuration effect is originated from the curvature effect of the interacting surfaces. The curved surfaces showed less repulsive energy than flat surfaces at the same interacting surface area. The configuration dependency of interaction energy agreed with the previous analytical solution obtained under the linearized P-B equation. The approach and results present in this report would be applicable in predicting colloidal behavior of cylindrical particles.

“…have been widely employed as templates to fabricate structural functional inorganic materials. The nano-particles, 12,13 two-dimensional arrays of nanoparticles, 14,15 nanowires, 16,17 nanotubes, 18 nanospheres 19 and other nanostructured complex architectures 20 have been achieved by the facile biotemplate approach. Particularly, some macroscopical bio-templates with micro-/nanoscale structures, such as insect wings, plant leaves, 4,21 and silk fibers, 2,22 have also been used as templates to fabricate functional inorganic materials with novel architectures, which may find potential applications to catalysis, magnetism, separation, gas sensors, electrical and optical devices and so on.…”

Rape-, sweet potato-and camellia-pollen-templated SiO 2 hierarchical structures with species-specific surface morphologies were prepared through a facile surface sol-gel and succedent calcination process. Various-morphology SiO 2 replicas with complex structures, such as about 50-µm-length and 20-µm-width high-fidelity ellipsoidal replicas with about 5-µm uniform meshes, about 40-µm spheres with 2-µm taper-like protuberances and 15-µm spheres with troughs, were obtained from using rape-, sweet potato-and camellia pollen grains as templates, respectively. The results of N 2 adsorption-desorption isotherms indicate that both rape-and camellia-pollentemplated SiO 2 replicas show type IV-like isotherm with the characteristics of mesoporosity and corresponding Brunauer-Emmett-Teller (BET) surface areas are 10.5 and 5.2 m 2 •g -1 , respectively. The Barrett-Joyner-Halenda (BJH) pore size distribution of the rape-pollen-templated SiO 2 replicas presents smaller pores centered at 3.6 nm and bigger pores centered at 8.6 nm with a broad distribution whereas the camelliapollen-templated SiO 2 replicas display narrow BJH pore size distribution centered at 20 nm. The biofabrication procedure using ubiquitous, inexpensive and environment-friendly pollen grains as a biotemplate holds a promise as a simple route to construct controlled complex porous oxides via simple chemical methods.
