Abstract: There is a method for forming a three dimensional or porous graphene electrode pattern on a substrate, the method including providing a substrate; coating the substrate with a lignin-polymer composite film; exposing a first part of the coated lignin-polymer composite film to a laser beam for transforming the first part into the graphene pattern; and removing a second part of the coated lignin-polymer composite film, which was not exposed to the laser beam, by placing the second part in water. The lignin-polymer composite film includes (1) a water-soluble alkaline lignin, (2) a polymer having bonding properties, and (3) a solvent, and an amount of the water-soluble alkaline lignin in the lignin-polymer composite film is between 5 and 60% by weight.

Abstract: There is a viscoelastic strain sensor that includes a sensing layer including a viscoelastic material, the viscoelastic material including a viscoelastic hydrogel and a conductive nanofiller. The viscoelastic material has a fractional resistance change that increases with an increase of an applied tensile strain, and the viscoelastic material has a fractional resistance change that decreases with an applied compressional strain.

Abstract: An osmotic energy conversion system includes a housing having a first inlet and a second inlet, an MXene lamellar membrane located inside the housing and configured to divide the housing into a first chamber and a second chamber, and first and second electrodes placed in the first and second chambers, respectively, and configured to collect electrical energy generated by a salinity-gradient formed by first and second liquids across the MXene lamellar membrane. The first chamber is configured to receive the first liquid at the first inlet and the second chamber is configured to receive the second liquid at the second inlet. The first liquid has a salinity lower than the second liquid, and the MXene lamellar membrane includes plural nanosheets of MXene stacked on top of each other.

Abstract: A semiconductor device includes a substrate, a gate arranged on the substrate, a dielectric arranged on the gate, a channel arranged on the dielectric, a source electrically coupled to the channel, and a drain electrically coupled to the channel. Each of the gate, dielectric, channel, source, and drain includes a corresponding mixture of hafnium dioxide (HfCte) and zinc oxide (ZnO) layers and at least two of the gate, dielectric, channel, source, and drain comprise different mixtures of the hafnium dioxide and zinc oxide layers.
