Trapping and release of cargo molecules from a micro-stamped mesoporous thin film controlled by poly(NIPAAm-co-AAm)

Controlled release of guest molecules from mesoporous silica particles based on a pH-responsive polypseudorotaxane motif.

Laser Micro-Raman Spectroscopy of CVD Nanocrystalline Diamond Thin Film

Laser micro-Raman spectroscopy is an ideal tool for assessment and characterization of various types of carbon-based materials. Due to its special optical properties (CrN) coated stainless steel substrates. NCD films have been investigated by laser micro-Raman spectroscopy. The fingerprint of diamond based materials is in the spectral region of 1000-1600 cm-1 in the first order of Raman scatter...

Trapping and release of CO2 guest molecules by amorphous ice.

Interactions of 13CO2 guest molecules with vapor-deposited porous H2O ices have been examined using temperature-programmed desorption (TPD) and Fourier transform infrared (FTIR) techniques. Specifically, the trapping and release of 13CO2 by amorphous solid water (ASW) has been studied. The use of 13CO2 eliminates problems with background CO2. Samples were prepared by (i) depositing 13CO2 on top...

Plasmonic Light Trapping Transforming Thin-Film Photovoltaics

The photovoltaics (PV) market represents the fastest growing renewable energy technology, with a 35% annual growth rate, which is projected to be worth $150B by 2018.[1] The global cumulative installed PV capacity has exceeded 140 GW in 2013 and is generating 160 TWh/year of electricity, representing 0.85% of worldwide electricity demand. At the present growth rate, it is projected that over 20...

PZT Thin-Film Meso- and Micro Devices

This paper consists of three major topics. The first topic is a review of challenges encountered in PZT thin film fabrication. Currently, sol-gel processing is one of the most promising techniques to fabricate PZT thin films. There are, however, several major challenges, including crack formation, thermally unstable electrodes, and poor piezoelectric properties. The second topic reveals some in...
