Methods of forming a hierarchical porous monolith are provided. The methods include mixing a monomer, a silica precursor and a catalyst in a solvent to form a mixture. The methods also include adding a gelling agent to the mixture to form a polymer-silica composite gel. The polymer-silica composite gel undergoes a phase separation to separate from the solvent and the unreacted silica precursor. The method further includes drying the polymer-silica composite gel to evaporate the solvent to form a polymer-silica monolith and processing the polymer-silica monolith to form at least one of a polymer monolith, a carbon monolith, a silica monolith and a carbon-silica monolith.

Hierarchical porous monoliths and methods for their preparation and use

A metal nanoparticles-doped porous carbon bead having an average size of about 0.4 millimeter (mm) to about 0.6 mm is provided. The metal nanoparticles-doped porous carbon bead is doped with silver, copper, or combinations thereof.

Metal nanoparticles-doped antibacterial agents and methods of preparation and use

Bi-metal nanoadsorbents and methods for their preparation and use are provided. Methods of using bi-metal nanoadsorbents to remove contaminants from samples, such as water, are also provided.

Bi-metal nanoadsorbents and methods for their preparation and use

A pressure-sensitive adhesive material including a visco-elastic layer and an elastic layer is provided. In some embodiments, a reusable pressure-sensitive adhesive material exhibiting high adhesive strength after repeated cycles of adhesion and detachment is provided. In some embodiments, methods of making a pressure sensitive adhesive material are provided.

Composite reusable adhesive

Methods and devices for preparing microscale polymer relief structures from a thin polymer layer on an absorbing substrate are described. The described methods are ultrafast (about 8 nanoseconds) and allow formation of patterned microstructures having complex morphologies and narrow line widths that are an order of magnitude smaller than the masks used in the methods.

Micropattern generation with pulsed laser diffraction

Techniques related to miniature lenses and lens arrays are generally described herein. The described techniques may be embodied in apparatuses, systems, methods and/or processes for making and using such lenses. In some examples, the various techniques may be utilized for miniature lenses such as nanometer to micron sized spherical lenses or lens arrays. An example process may include dewetting polymer films to form such lenses. The resulting lens-size may be tunable from about 200 nm to a few tens of microns, and more particularly in a range from about 200 nm to about 10 &#x3bc;m with spherical shapes of contact angles ranging from about 30&#xb0; to about 150&#xb0;. The resulting lenses may be tunable polymeric structures formed generally by self-organized room temperature dewetting of ultrathin polymer films by reducing the surface tension.
