The formation of porous nanostructures on surfaces and the control their size shape is fundamental for various applications. creation nanotubes particularly difficult to implement without aid hard rigid templates. Recently, methods that form nanotubular structures in a straightforward manner direct templating, e.g. soft have been highly sought after. Here we propose use “soft templating” via se...

About ten years ago Ryoo and co-workers [1,2] reported the hard-templating (HT) synthesis of ordered mesoporous carbons (OMCs) by using ordered mesoporous silicas (OMSs) as hard templates. Five years afterward the soft-templating (ST) synthesis of OMCs has been discovered [3-6]. Significant progress has been made in both hardand soft-templating synthesis of OMCs [7-10]. Major advances in the sy...

BACKGROUND The purpose of our investigation was to compare a digital templating system to conventional templating techniques when preoperatively planning for total hip arthroplasty. METHODS We included 18 consecutive patients with primary osteoarthritis undergoing uncemented total hip arthroplasty in our study. At separate sittings, we independently conducted preoperative templating. They per...

Templating processes for creating polymerized hydrogels are reviewed. The use of contact photonic crystals and of non-contact colloidal crystalline arrays as templates are described and applications to chemical sensing and device fabrication are illustrated. Emulsion templating is illustrated in the formation of microporous membranes, and templating on reverse emulsions and double emulsions is ...

Water-insoluble organic compounds are often used in aqueous environments in various pharmaceutical and consumer products. To overcome insolubility, the particles are dispersed in a medium during product formation, but large particles that are formed may affect product performance and safety. Many techniques have been used to produce nanodispersions-dispersions with nanometre-scale dimensions-th...

DOI: 10.1002/admi.201600621 orientations in thin films. First of all, elucidating the effect of excited state delocalization, including singlet excitons, triplet excitons, and charge transfer states, on charge generation and recombination processes in crystalline thin films and molecular heterointerfaces requires controlled access to varied molecular orientations. A lying-down orientation provi...

Elaborate one-dimensional photonic crystals are constructed from a variety of organic and biopolymers, which can be dissolved or melted, by templating the solution-cast or injection-molded materials in porous silicon or porous silicon dioxide multilayer (rugate dielectric mirror) structures. After the removal of the template by chemical dissolution, the polymer castings replicate the photonic f...

Chiral surfaces are of growing importance as a result of their potential for use in enantioselective chemical processes. By far the most widely used and commonly studied chiral surfaces are those prepared by templating of achiral surface with chiral organic ligands. It is possible, however, to prepare naturally chiral surfaces by a number of means. This paper describes the various types of chir...

with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...

As digital radiography becomes more prevalent, several systems for digital preoperative planning have become available. The purpose of this study was to evaluate the accuracy and efficiency of an inexpensive, cloud-based digital templating system, which is comparable with acetate templating. However, cloud-based templating is substantially faster and more convenient than acetate templating or l...
