Mesoporous silica material based drug delivery systems (DDSs) containing curcumin show biocompatibility in normal cells and an effective anti-cancer effect cancer cells.
A mesoporous silica (SBA-15) has been chemically modified with 2-mercaptopyrimidine using the homogeneous route. This synthetic route involved reaction of 3-chloropropyltriethoxysilane prior to immobilization on support. The resulting material characterized by powder X-ray diffraction, nitrogen gas sorption, FT-IR and MAS NMR spectroscopy, thermogravimetry elemental analysis. solid was employed as a Cd(II) adsorbent from aqueous solutions at room temperature. effects several variables...

Mesoporous silicas (SBA-15 and MCM-41) have been functionalized by two different methods. Using the heterogeneous route silylating agent, 3-chloropropyltriethoxysilane, was initially immobilized onto mesoporous silica surface to give chlorinated Cl-SBA-15 or Cl-MCM-41. In a second reaction multifunctionalized N,S donor compound (2-mercaptobenzothiazol) incorporated obtain denoted as MBT-SBA-15-Het MBT-MCM-41-Het. homogeneous route, functionalization achieved via one step of with an organic...

The new title complexes of tantalum are true hydrides whereas the niobium have bonding interactions among three hydrogen atoms, as evidenced by short n.m.r. T1 values and unusual couplings 1J(H,H) which vary with temperature from less than 3 to about 100 Hz.
Abstract In this work, a mesoporous silica has been chemically modified with 5‐mercapto‐1‐methyl‐1‐H‐tetrazol using the homogeneous route (MTTZ‐HMS).
