Kinematically Redundant Octahedral Motion Platform for Virtual Reality Simulations
, 2017 We propose a novel design of a parallel manipulator of Stewart Gough type for virtual reality application of single individuals; i.e. an omni-directional treadmill is mounted on the motion platform in order to improve VR immersion by giving feedback to ...

Surface magnetism in ZnO/Co3O4 mixtures [PDF]
, 2009 We recently reported the observation of room temperature ferromagnetism in mixtures of ZnO and Co3O4 despite the diamagnetic and antiferromagnetic character of these oxides respectively.

Large tunneling magnetoresistance in octahedral Fe3O4 nanoparticles
AIP Advances, 2016 We have observed large tunneling Magnetoresistance (TMR) in amine functionalized octahedral nanoparticle assemblies. Amine monolayer on the surface of nanoparticles acts as an insulating barrier between the semimetal Fe3O4 nanoparticles and provides ...

Stabilizing hidden room-temperature ferroelectricity via a metastable atomic distortion pattern
Nature Communications, 2020 Previous studies are limited to modulate oxygen octahedral rotation angles within the same pattern, and engineering the pattern remains a challenge. Here, the authors demonstrate a designed nonequilibrium oxygen octahedral rotation pattern leads to room ...

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Advanced Functional Materials, EarlyView.This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

SOME NEW SULFONATO ADDUCT: SYNTHESIS AND SPECTROSCOPIC STUDIES
Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2015 Three new adducts have been synthesized and studied by infrared and NMR spectroscopies. The suggested structures are discrete with a pyridine -3- sulfonate acting as a tri O-chelating and N-donor or as a non σ coordinating ligand, a 4 ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation
Advanced Functional Materials, EarlyView.This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.
