Surface heterogeneity plays an important role in controlling colloidal phenomena. This study investigated the self-aggregation and bacterial adsorption of self-assembled monolayer coated gold nanoparticles (AuNPs) with different surface compositional and s ...
It has been suggested that amphiphilic amino acids play an important role in the adsorption of proteins on nanostructured surfaces with an ordered, striped domain structure such as those presented by monolayer-protected metal nanoparticles (MPMNs). We have ...
Understanding as well as rapidly screening the interaction of nanoparticles with cell membranes is of central importance for biological applications such as drug and gene delivery. Recently, we have shown that "striped" mixed-monolayer-coated gold nanopart ...
A significant redn. in the energy costs assocd. with the cryogenic sepn. of ethylene-ethane and propylene-propane mixts. could potentially be realized through the use of selective solid adsorbents that operate at higher temps. The metal-org. frameworks M2( ...
The presence of H2O in postcombustion gas streams is an important technical issue for deploying CO2-selective adsorbents. Because of its permanent dipole, H2O can interact strongly with materials where the selectivity for CO2 is a consequence of its quadru ...
We explore the local electronic signatures of molecular adsorption at coordinatively unsaturated binding sites in the metal-organic framework Mg-MOF-74 using X-ray spectroscopy and first-principles calculations. In situ measurements at the Mg K-edge reveal ...
Methane (CH4) is an important greenhouse gas, second only to CO2, and is emitted into the atmosphere at different concentrations from a variety of sources. However, unlike CO2, which has a quadrupole moment and can be captured both physically and chemicall ...

Zeolite adsorbents were evaluated for potential application in post-combustion CO2 capture using a new high-throughput gas adsorption instrument capable of measuring 28 samples in parallel. Among the zeolites tested, Ca-A exhibits the highest CO2 uptake (3 ...
We report on low-temperature scanning tunneling microscopy observations demonstrating that individual Ti atoms on hexagonal boron nitride dissociate and adsorb hydrogen without measurable reaction barrier. The clean and hydrogenated states of the adatoms a ...
Semiconducting single-walled carbon nanotubes (SWCNTs) fluoresce in the near-IR and are promising as optical sensors when functionalized to enable analyte recognition. SWCNT sensors with enhanced fluorescence emission have been hypothesized to have greater ...
