“…It is well known that the surface morphology and crystallinity affect the physical and electrical properties of PANI . According to the SEM imaging and the X‐ray diffraction, the surface morphology and diffraction pattern of the PANI samples were observed almost identical before and after deprotonation (Figure S1 and S2, Supporting Information).…”

The photo-responsive characteristics of polyaniline (PANI) thin films are investigated as a function of the doping states. The doping levels are controlled by treating as-prepared, acid-doped PANI with aqueous ammonia solutions. Spectroscopic analyses confirm the changes in the doping states by evolution or decrease of characteristic peaks. The electrical and photoresponsive properties are significantly affected by the doping states of the PANI thin films. The photocurrent and photovoltage under irradiation of controlled wavelengths from various laser sources are measured. While the photocurrent follows the trends of electrical conductivity upon dedoping, the photovoltage is related to the absorption and photocharge generation of the PANI samples.

“…CTAB CTAB (C 16 H 33 N(CH 3 ) 3 Br), molecular weight 364.45 g/mol) is a quaternary ammonium surfactant that is one of the main components of some buffers for the extraction of DNA. CTAB is widely used in the synthesis of gold nanoparticles (spheres and rods) and mesoporous silicate materials [43]. As other surfactants, CTAB forms micelles in aqueous solutions when a temperature of 30 • C is reached.…”

“…For these properties, CTAB has been the first template used for the synthesis of mesoporous materials. The products of sol–gel synthesis combined with CTAB possess regular arrays of uniform channels, the dimensions of which can be tailored tuning different factors, as the choice of surfactant, auxiliary chemicals, and reaction conditions [ 43 ].…”

Bioactive glasses (BGs) are traditionally known to be able to bond to living bone and stimulate bone regeneration. The production of such materials in a mesoporous form allowed scientists to dramatically expand the versatility of oxide-based glass systems as well as their applications in biomedicine. These nanostructured materials, called mesoporous bioactive glasses (MBGs), not only exhibit an ultrafast mineralization rate but can be used as vehicles for the sustained delivery of drugs, which are hosted inside the mesopores, and therapeutic ions, which are released during material dissolution in contact with biological fluids. This review paper summarizes the main strategies for the preparation of MBGs, as well as their properties and applications in the biomedical field, with an emphasis on the methodological aspects and the promise of hierarchical systems with multiscale porosity.

“…Conducting polymers have continuously attracted worldwide attention of researchers owing to their metallic conductivity and semiconductor properties [1][2][3][4], since polyacetylene (PA) was fabricated by H. Shirakawa, A. G. Macdiarmid, and A. J. Heeger in the 1970's [5]. Moreover, they have found a broad range of applications in sensors or electronic junctions [6], optical equipment [7], electrode materials [8], electrochromism [9], and ion transport [10]. Polypyrrole (PPy), one of the most popular polymers among the family of conducting polymers, has superior performance such as environmental stability and biocompatibility [11].…”

is synthesized via in situ chemical oxidative polymerization in the presence of acid fuchsin (AF) which works as both the dopant and structure-guiding agent for polymerization of pyrrole. The electronic conductivity is measured in detail, showing that the addition of AF plays a key role in regulating and even deciding the morphology and the electronic conductivity of the resulting PPy. In addition, the effects of some polymerization conditions including temperature, reaction time, kinds of doping acid and oxidant on the electronic conductivity are investigated. And the reason for the changes of performance are also explained.
