“…So far mesoporous silicas including the families of M41S, Santa Barbara Amorphous type material (SBA-n), anionicsurfactant-templated mesoporous silica (AMS), etc., have been reported (Liu et al, 2005;Sun et al, 2007;Chew et al, 2010). However, the CO 2 adsorption capacities are not high enough, especially, at atmospheric pressure, to allow their practicability.…”

Global warming resulting from the emission of greenhouse gases, especially CO 2 , has become a widespread concern in the recent years. Though various CO 2 capture technologies have been proposed, chemical absorption and adsorption are currently believed to be the most suitable ones for post-combustion power plants. The operation of the chemical absorption process is reviewed in this work, together with the use of absorbents, such as the ionic liquid, alkanolamines and their blended aqueous solutions. The major concerns for this technology, including CO 2 capture efficiency, absorption rate, energy required in regeneration, and volume of absorber, are addressed. For adsorption, in addition to physical adsorbents, various mesoporous solid adsorbents impregnated with polyamines and grafted with aminosilanes are reviewed in this work. The major concerns for selection of adsorbent, including cost, adsorption rate, CO 2 adsorption capacity, and thermal stability, are compared and discussed. More effective and less energy-consuming regeneration techniques for CO 2 -loaded adsorbents are also proposed. Future works for both absorption and adsorption are suggested.

“…In recent years, mesoporous silica nanoparticles (MSNs) have been well developed as effective drug storage vehicles in drug delivery systems due to their large pore volume (~1cm 3 /g), high surface area (> 1000 m 2 /g), ease of functionalization, low toxicity and biodegradability [1][2][3]. Exclusively in drug delivery, mesoporous silica is often used with modification to suit treatment needs.…”

Nanotechnology has been utilized in medicine for therapeutic drug delivery and the development of treatments for a variety of diseases and disorders. Mesoporous silica nanoparticles (MSN), which combine both unique properties of nanomaterials and mesostructured substances, have aroused special attention in biomedical research field due to its great advantages in many aspects such as well biocompatible, unique properties of tunable pore size and structure, large surface areas and pore volumes, controllable morphology and modifiable surfaces, high chemical and thermal stabilities. In this study, the microwave was utilized to synthesize MSN under 100 W, 300 W and 450 W heating powers. All MSNs was tested for adsorption and release of an anti-inflammatory and anti-cancer drug, ibuprofen. The characterization revealed that the MSN prepared under 450 W (MSN450) produced the most ordered and prominent mesoporous structure compared to lower power applied. MSN450 exhibited the highest ibuprofen adsorption, followed by MSN300 and MSN100, confirming that more ordered MSN demonstrated higher adsorptivity toward ibuprofen. For the release study, MSN450 showed the slowest release rate of ibuprofen, followed by MSN300 and MSN100. All MSNs was found to exhibit good activity for the ibuprofen adsorption and release.

Partikel nano silika mesoliang, yang menggabungkan kedua-dua ciri-ciri yang unik bahan nano dan bahan struktur meso, telah membangkitkan perhatian khusus dalam bidang penyelidikan bioperubatan kerana kelebihan yang besar dalam banyak aspek seperti bioserasi, ciri-ciri unik bolehubah saiz liang dan struktur, kawasan permukaan dan isipadu liang yang besar, morfologi bolehkawal dan permukaan boleh ubahsuai, serta tinggi kestabilan kimia dan haba. Dalam kajian ini, gelombang mikro telah digunakan untuk mensintesis partikel nano silika mesoliang (MSN) dibawah kuasa pemanasan 100 W, 300 W dan 450 W. Semua MSN telah diuji untuk penjerapan dan pembebasan ubat anti-radang dan anti-kanser, ibuprofen. Pencirian mendedahkan bahawa MSN yang disediakan di bawah 450 W (MSN 450 ) menghasilkan struktur paling tersusun dan terbaik dibandingkan dengan kuasa lebih rendah. MSN 450 telah mencapai penjerapan ibuprofen tertinggi, diikuti dengan MSN 300 dan MSN 100 , mengesahkan bahawa MSN yang lebih tersusun menunjukkan penjerapan ibuprofen lebih tinggi. Untuk kajian

“…Soon, they were utilized in the fields of catalysis, separation, 25 ion exchange, molecular sieving, and adsorption. [5][6][7][8][9][10] It did not take long to realize that the new dimension of the well ordered pores could lead to entirely new types of applications. Mesoporous silicas were used, for example, to catalyze the formation of conductive polymers within their pores, [11][12][13][14][15] or 30 even as templates for some of the first synthetic procedures of conductive carbon nanowires.…”
