Radiant panel with varied channel geometries for enhanced retention of tubing
A radiant panel having a U-shaped channel or groove with substantially parallel vertical sides. Because varied diameter tubing pressed into curved channels of varying radius will change their shape from round to oval by different amounts, channel width will be reduced at curved channel areas as appropriate, based on tubing size and channel radius. This reduction in curved channel width compared to straight channel width allows for a consistent friction force to be developed upon pressing the tubing into a channel. The depth of groove may be varied to allow for the increased vertical dimension of tubing which is deformed from round to oval by bending forces, so that tubing can be installed consistently flush with the surface of the radiant panel. Varying width and depth will also tend to maximize the contact area of tube to conductive surface, thereby improving the flow of heat from tube to radiant panel. |

Biosensor for detecting TNT
A biosensor for detecting nitrotoluenes. Two P. putida host populations (H-I and H-II) are engineered. H-1 undergoes fluorescence when a nitrotoluene is detected but it is also engineered to metabolize nitrotoluenes to toluene as its sole nitrogen-source.

In H-II, ACC is the N-source and metabolizes toluene as the sole carbon and energy source available. The H-II cells are engineered to not be able to use medium fructose. The H-II population has a promoter/GFP construct with a promoter sensitive to toluene and thus they fluoresce from that first nitrotoluene metabolite i.e. toluene, produced by the H-I cells.

Functionalized mesoporous silica via an aminosilane surfactant ion exchange reaction: controlled scaffold design and nitric oxide release
Nitric oxide-releasing mesoporous silica nanoparticles (MSNs) were prepared using an aminosilane-template surfactant ion exchange reaction. Initially, bare silica particles were synthesized under basic conditions in the presence of cetyltrimethylammonium bromide (CTAB). These particles were functionalized with nitric oxide (NO) donor precursors via the addition of aminosilane directly to the particle sol, and a commensurate ion exchange reaction between the cationic aminosilanes and CTAB. N-diazeniumdiolate NO donors were formed at the secondary amines to yield NO-releasing silica MSNs. Tuning of the ion exchange-based MSN modification approach allowed for the preparation of monodisperse particles ranging from 30 to 1100 nm. Regardless of size, the MSNs stored appreciable levels of NO (0.4-1.5 μmol/mg) with tunable NO-release durations (1-33 h) dependent on the aminosilane modification. The range of MSN sizes and NO release demonstrate the versatility of this strategy. |
