A method of preparing a porous sheet includes mixing a matrix material dispersion including a matrix material dispersed in a first dispersion medium with a microorganism dispersion including microorganisms in a second dispersion medium, to form a mixture. The first and the second dispersion media are removed from the mixture to form a matrix sheet, and the microorganisms are decomposed from the matrix sheet to form the porous sheet.

Methods of forming a battery include forming a thin graphene cathode on a substrate. A lithium anode is formed and an electrolyte is formed between the thin graphene cathode and the lithium anode.

Thin cathode for micro-battery

Batteries include an anode, an electrolyte having a high solubility for lithium ions and oxygen, and a cathode formed on a substrate. Lithium ions migrate from the anode through the electrolyte to form LiOat a surface of the cathode. A current collector positioned in the electrolyte, the electrolyte separating the anode from the cathode.

Porous sheets

A crosslinked self-assembled monolayer (SAM), comprising surface groups containing a nitrogen-heterocycle, was formed on an oxygen plasma-treated silicon oxide or hafnium oxide top surface of a substrate. The SAM is covalently bound to the underlying oxide layer. The SAM was patterned by direct write methods using ultraviolet (UV) light of wavelength 193 nm or an electron beam, forming a line-space pattern comprising non-exposed SAM features. The non-exposed SAM features non-covalently bound DNA-wrapped carbon nanotubes (DNA-CNT) deposited from aqueous solution with a selective placement efficiency of about 90%. Good alignment of carbon nanotubes to the long axis of the SAM features was also observed. The resulting patterned biopolymer features were used to prepare a CNT based field effect transistor.

Nitrogen heterocycle-containing monolayers on metal oxides for binding biopolymers

The present invention relates to a water-soluble polymer complex that includes a water-soluble block copolymer and a magnetic nanoparticle, wherein the water-soluble polymer complex has a nonzero net magnetic moment in the absence of an applied magnetic field at ambient temperatures. The water-soluble block copolymer is preferably a diblock or triblock copolymer and the magnetic nanoparticle is preferably a ferrimagnetic or ferromagnetic nanoparticle. The water-soluble complexes may be derivatized with reactive groups and conjugated to biomolecules. Exemplary water-soluble polymer complexes covered under the scope of the invention include PEG-b-PAAmodified CoFeO; NH-PEG-b-PAAmodified CoFeO; PNIPAM-b-PAAmodified CoFeO; and mPEG-b-PCL-b-PAA modified CoFeO.

Aqueous soluble ferrimagnets stabilized by block copolymers

Batteries and methods of forming the same include a lithium anode, an electrolyte having a high solubility for lithium ions and oxygen, and a thin graphene cathode formed on a substrate. Lithium ions migrate from the lithium anode through the electrolyte to form LiOat a surface of the thin graphene cathode.

A thermo-responsive shear-thinning photo-curable composition comprises water, a linear amphiphilic polyether ABA triblock copolymer comprising at least one pendent ene group (*&#x2014;CH&#x2550;CH) capable of undergoing a thiol-ene reaction, a water-soluble crosslinking agent comprising two or more methylenethiol groups (*&#x2014;CHSH), and a photoinitiator. Under non-shear conditions and a triblock copolymer concentration suitable for direct-write printing, the composition is a viscoelastic solid (hydrogel) at a temperature of about 15&#xb0; C. to about 45&#xb0; C., and is a free-flowing liquid (sol) between 0&#xb0; C. and about 10&#xb0; C. The hydrogel form can be shear-thinned at about 15&#xb0; C. to about 45&#xb0; C. to form a sol suitable for a direct-write printer using an extruding print-head. The compositions covalently crosslink when flood-exposed to ultraviolet radiation. The compositions have utility in forming three-dimensional scaffolds for growing living cells.

A method of preparing particles comprises forming by optical lithography a topographic template layer disposed on a surface of a substrate, which is suitable for spin casting. The template layer comprises a non-crosslinked template polymer having a pattern of independent wells therein for molding independent particles. Spin casting a particle-forming composition onto the template layer forms a composite layer comprising the template polymer and the particles disposed in the wells. The composite layer is removed from the substrate using a stripping agent that dissolves the template polymer without dissolving the particles. The particles are then isolated.
