Newly discovered sheets of nanoscale “cubes” make excellent catalysts Two-dimensional materials are a breakthrough in nanotechnology, realizing materials with exotic electronic and physical properties which are specific to their sheet-like nature. While graphene is well known, there has also been a lot of focus on transition metal chalcogenides (TMCs), composed of a transition metal and a group 16 element like sulfur or selenium. For example, nanosheets of TMCs have been shown to be able to emit light and show excellent performance as transistors. https://lnkd.in/gDqSQnAC #nanotechnology #materialsscience #advancedmaterials #engineering #electronics #chemistry #science

In this research, the team utilized triazacoronene, possessing a chemical structure similar to graphene, and introduced bulky pendant functional groups to its periphery. By introducing steric hindrance from these pendant groups, the team successfully suppressed the stacking of two-dimensional polymer intermediates during the polymerization of triazacoronene monomers. This led to increased solubility of the intermediates and facilitated the synthesis of two-dimensional polymers with higher degree of polymerization and fewer defects, resulting in outstanding electrical conductivity after p-type doping. #nanotechnology #graphene #materialsscience #electronics #semiconductor #engineering #innovation #scienceandtechnology

In a recent breakthrough, researchers have successfully developed semiconducting epigraphene (SEG) on single-crystal silicon carbide #substrates, addressing the longstanding challenge of creating viable semiconducting #graphene. This SEG exhibits a band gap of 0.6 eV and impressively high room temperature mobilities exceeding 5,000 cm2 V−1 s−1, significantly surpassing the performance of traditional silicon and other two-dimensional semiconductors. By employing a quasi-equilibrium annealing method, the researchers achieved the formation of well-ordered SEG on macroscopic atomically flat terraces, with the lattice aligned with the SiC substrate. Crucially, SEG demonstrates robust chemical, mechanical, and thermal properties, allowing for seamless integration with conventional semiconductor fabrication techniques. This development holds promise for advancing nanoelectronics due to the pivotal role semiconducting graphene plays in graphene-based electronic devices. Read more https://lnkd.in/eaxUWXsb

https://lnkd.in/gCbmpAvH Article Title: LiF-MO (M=Co, Fe, Ni) Nanocomposite Thin Film as Anode Materials for Lithium-ion Battery Author(s): Wenyuan Liu, Changfeng Ke, Xuehai Yan, Li Duan, Lin Li and Chong Liu Journal: International Journal of Nanomaterials, Nanotechnology and Nanomedicine Journal ISSN: 2455-3492 Abstract: To investigate the electrochemical performance of MO (M=Co, Fe, Ni) nanostructures on lithium insertion and extraction, size-controlled LiF-MO nanocomposite thin-film electrodes, consisting of metallic M and M oxide (MO) nanoparticles in an amorphous, inert LiF matrix, were designed and fabricated using a RF sputtering system with metallic M and LiF mixture targets. The structural and electrochemical properties of nanocomposite thin-film electrodes were characterized using TEM, SAED, XRD, XPS, and electrochemical measurements. The results showed that MO particles with average particle sizes of ca.10nm were well-dispersed in LiF matrix to form a kind of homogeneous LiF-MO nanocomposite by the sputtering method. The inert medium of LiF provides an effective matrix to prevent the crystallization and agglomeration of MO during the deposition and electrochemical cycling of the thin film electrode, and then the well-formed nanophase structure in the nanocomposite thin-film electrodes leads to an excellent electrochemical cycling performance with the stable discharge specific capacity above 300mAh/g. #TiO2Thinfilmbatteries #Lithiumionbatteries #Nanocompositematerials #Anode #Electrochemicalproperties #Chemistry #OrganicChemistry #InorganicChemistry #PhysicalChemistry #AnalyticalChemistry #Biochemistry #TheoreticalChemistry #EnvironmentalChemistry #ChemicalEngineering #Peertechz #PeertechzPublications #PolymerChemistry #MedicinalChemistry #IndustrialChemistry #GreenChemistry #ChemicalSynthesis #ChemicalKinetics #Spectroscopy #Electrochemistry #Nanochemistry #SurfaceChemistry #QuantumChemistry #ChemicalBonding #Thermodynamics #ChemicalCatalysis #SupramolecularChemistry #MaterialsChemistry

There have been so many significant publications from Prof. Chrisey's (Doug Chrisey) lab over the years on photonic curing.  In the latest one, titled "Synthesis of Silicon and Germanium Oxide Nanostructures via Photonic Curing: a Facile Approach to Scale-Up Fabrication" published in ChemistryOpen  they focus on the potential of silicon oxide (SiOx) and germanium oxide (GeOx) nanostructures in transforming the landscape of energy storage technologies. Photonic curing with its rapid heating and cooling of the materials, enables the creation of nanostructures with unique properties. Combining the significant advantages in terms of speed, efficiency, and the ability to control the structural characteristics of the nanostructures  makes it a pivotal development for production-scale manufacturing in the field of energy storage and beyond.
