“…Besides displaying applications in semiconductor devices, CO 2 capture, proton conduction, luminescence, catalysis, energy conversion, and energy storage . These materials also display indispensable features such as great selectivity, excellent sensitivity, response and recovery time . The higher affinity and interaction of porous materials with water and boron ester linkers is due to the higher diffusion of nano‐channels.…”

Truxene and its congeners due to its structural, thermal, and optoelectronic properties, has recently became important not only in biological systems but also in the field of material and environmental sciences. The remarkable scope and its applicability ranging from sensory materials to photocatalysts and fluorescent probes, forces the scientific community to think about the design and construction of architecturally simple yet much powerful novel functional materials possessing the truxene scaffold(s) in their structures. Herein, we have focused to assemble a series of ground‐breaking achievements in recent years of truxene‐based functional materials with special emphasis on their applicability in material sciences and technology. We hope that the present review will boost the current scenario of truxene and its various domains.

“…The graphene samples were added to the ZrO 2 solution and held at 30 ℃ for 3 d until a powder had formed. The samples were then calcined in air at 600 ℃ for 2 h. Various ratios of the sensing material (5,10,20,30,40, and 50 wt%) were tested.…”

This paper reports a novel graphene (G)/zirconium dioxide (ZrO 2 ) nanocomposite produced using a sol-gel method with various weight percentages of graphene for use in humidity sensors. The morphological and structural properties of the (G/ZrO 2 ) were characterized using X-ray diffraction (XRD) , Fourier transform infrared (FTIR), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX). The response characteristics of the sensor, including sensitivity, hysteresis, response time, and recovery time, were investigated from theoretical as well as experimental perspectives. Experimental results revealed a linear functional relationship between shifts in the impedance of the sensor and variations in relative humidity. The sensor with 40 wt% G/ZrO 2 nanocomposite demonstrated a sensitivity (S = 4011) exceeding that of the other samples. At all humidity levels, the humidity hysteresis values remained low, and the response and recovery times were very rapid (5 and 20 s, respectively). These results demonstrate the considerable potential of using G/ZrO 2 nanocomposites in the further development of humidity sensors.

“…Presence of Si(Q3) species in initial stage of the synthesis resulted in disordered mesoporous silica. Setoguchi et al (52) studied the effect of various silica sources under strong acidic conditions (pH<1) with C1 6 PyCl surfactant. They found that use of sodium silicate produced high quality mesoporous silica analogous to MCM-41, whereas use of as received colloidal silica resulted in formation of non-mesoporous silica (52) .…”

ILICATE mesoporous materials have received widespread interest …..because of their potential applications. These novel materials, prepared either by soft-or hard-templating syntheses, become more and more important in many fields of science and technology such as adsorption, catalysis, separations, environmental processes, nanotechnology and biotechnology. According to IUPAC definition inorganic solids that contain pores with diameter in the size range of 2-50 nm are considered mesoporous materials, They also possess extremely high surface areas (>700 m 2 g −1) and narrow pore size distributions. This article review shows the current state of art and outlines the recent patents in mesoporous materials research in three general areas: synthesis, various mechanisms involved for porous structure formation and applications of mesoporous materials based on silica and alumina.
