Guided cold atom inertial sensors with membrane integrated photonics on atom trap integrated platforms
A guided cold-atom inertial sensor system comprises an atom trap integrated platform, a laser system, a magnetic field system, a control system, and a computing system. The laser system and magnetic field system are adapted to form a magneto-optical trap (MOT) about a suspended waveguide of the atom trap integrated platform made of membrane integrated photonics. After loading cold atoms from a MOT, the photonic atom trap integrated platform generates one-dimensional guided atoms with an evanescent field optical dipole trap (EF-ODT) along the optical waveguide to create guided atomic accelerometers/gyroscopes. Motion of atomic wavepackets in a superposition state is created along the guided atom geometry by way of state-dependent momentum kicks. The light-pulse sequence of guided atom interferometry splits, redirects, and recombines atomic wavepackets, which allows measurement of atom interference fringes sensitive to inertial forces via a probe laser. |

Method for producing renewable fuel
A process for preparing hydrocarbons from an oxygenated hydrocarbon feedstock, such as animal fat, having a high nitrogen impurity is described. Hydrotreatment of the oxygenated feedstock occurs in a first hydrotreating bed arranged downstream of a polishing bed. A gaseous phase is removed and the liquid hydrotreated phase is fed to the polishing bed arranged upstream of the first hydrotreating bed together with fresh hydrogen. The process effectively removes nitrogen impurities from the resultant hydrocarbon product causing an improved cloud point after isomerisation, and the arrangement makes efficient use of fresh hydrogen for polishing, providing a polished hydrocarbon product rich in dissolved hydrogen. Part of the product can be used as hydrocarbon diluent in the downstream hydrotreating bed, and/or withdrawn between the polishing and hydrotreating bed and isomerised in an isomerisation reactor. |

Carbon nanofiber-based hydrodesulfurization catalyst with molybdenum oxide and cobalt oxide
Carbon nanofiber doped alumina (Al—CNF) supported MoCo catalysts in hydrodesulfurization (HDS), and/or boron doping, e.g., up to 5 wt % of total catalyst weight, can improve catalytic efficiency. Al—CNF-supported MoCo catalysts, (Al—CNF—MoCo), can reduce the sulfur concentration in fuel, esp. liquid fuel, to below the required limit in a 6 h reaction time. Thus, Al—CNF—MoCo has a higher catalytic activity than Al-MoCo, which may be explained by higher mesoporous surface area and better dispersion of MoCo metals on the AlCNF support relative to alumina support. The BET surface area of Al-MoCo may be 75% less than Al—CNF—MoCo, e.g., 166 vs. 200 m2/g. SEM images indicate that the catalyst nanoparticles can be evenly distributed on the surface of the CNF. The surface area of the AlMoCoB5% may be 206 m2/g, which is higher than AlMoCoB0% and AlMoCoB2%, and AlMoCoB5% has the highest HDS activity, removing more than 98% sulfur and below allowed levels. |

11-arylcinnolino[2,3-f]phenanthridinium salts and method for producing the same
The present invention provides 11-arylcinnolino[2,3-f]phenanthridinium salt compounds and method for producing the same by highly regioselective synthesis of 11-phenylimino[2,3-f]phenanthridin-9-ium salts from 2-azobiaryls and alkenes under catalysis of palladium, through double oxidative C—H coupling of alkenes, to give the polycyclic cinnolinophenanthridinium salts in moderate yields. The reaction mechanism involves ortho C—H olefination of 2-azobiaryls by alkenes, intramolecular aza-Michael addition, β-hydride elimination, electrophilic palladation followed by intramolecular C—H activation and reductive elimination. The prepared quaternary ammonium salts are candidate materials for solution-processable OLED and bioimaging materials. |
