	abstract = {CdS incorporated Si-MCM-48 and Ti-MCM-48 cubic phased mesoporous photocatalysts were prepd. by a two-step modification synthetic approach under relatively mild conditions.  A highly efficient (24.8\%, apparent quantum yield (AQY)) photocatalyst for visible light (λ > 400 nm) enabled solar hydrogen evolution can be realized by assembling CdS with Ti-MCM-48 cubic mesoporous materials in the absence of a noble metal co-catalyst.  The photocatalytic mechanism was thoroughly investigated and demonstrated by conducting a wealth of characterization techniques such as powder X-ray diffraction (XRD), nitrogen adsorption isotherm, transmission electron microscopy (TEM), UV-visible diffuse reflectance spectroscopy (DRS), XPS, UPS (UVPS), at. absorption spectroscopy (AAS), photoluminescence (PL) spectroscopy, time-resolved fluorescence emission decay, and ESR (EPR) spectroscopy studies.  This work is the first to unambiguously identify the band positions of both CdS and TiO2 encapsulated in porous materials.  The photocatalytic activity of the CdS incorporated Ti-MCM-48 mesoporous photocatalysts was found to be dependent on the content of both CdS and TiO2.  A correlation between the electron injection efficiency and the photocatalytic activity was established as well in the CdS incorporated Ti-MCM-48 mesoporous photocatalysts. [on SciFinder(R)]},

	abstract = {Given the increased use of iron-contg. nanoparticles in a no. of applications, it is important to understand any effects that iron-contg. nanoparticles can have on the environment and human health.  Since iron concns. are extremely low in body fluids, there is potential that iron-contg. nanoparticles may influence the ability of bacteria to scavenge iron for growth, affect virulence and inhibit antimicrobial peptide (AMP) function.  In this study, Pseudomonas aeruginosa (PA01) and AMPs were exposed to iron oxide nanoparticles, hematite (α-Fe2O3), of different sizes ranging from 2 to 540 nm (2 {\textpm} 1, 43 {\textpm} 6, 85 {\textpm} 25 and 540 {\textpm} 90 nm) in diam.  Here we show that the greatest effect on bacterial growth, biofilm formation, and AMP function impairment is found when exposed to the smallest particles.  These results are attributed in large part to enhanced dissoln. obsd. for the smallest particles and an increase in the amt. of bioavailable iron.  Furthermore, AMP function can be addnl. impaired by adsorption onto nanoparticle surfaces.  In particular, lysozyme readily adsorbs onto the nanoparticle surface which can lead to loss of peptide activity.  Thus, this current study shows that co-exposure of nanoparticles and known pathogens can impact host innate immunity.  Therefore, it is important that future studies be designed to further understand these types of impacts. [on SciFinder(R)]},

The authors detailed surface investigation revealed that the overall degrdn. of RhB is enhanced due to the high surface percentage content of Ti-O-Si species, high crystallinity of titania phase, and its effective dispersion on a high surface area porous silica support.
