Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Fast separation of two trapped ions

New Journal of Physics, 2015
We design fast protocols to separate or recombine two ions in a segmented Paul trap. By inverse engineering the time evolution of the trapping potential composed of a harmonic and a quartic term, it is possible to perform these processes in a few ...

Interfacial Mn‐Carbon Nitride Synergy Enables Selective Photocatalytic C─H Chlorination via Single‐Atom Catalysis

Angewandte Chemie International Edition, EarlyView.
A manganese single‐atom photocatalyst on functionalised carbon nitride enables selective visible‐light‐driven C(sp2)─H chlorination. DFT‐supported mechanistic studies indicate that photoinduced charge separation activates NCS, while isolated Mn sites stabilize Mn─Cl intermediates at the catalyst interface.

Efficient associative ionization of ultracold lithium and the long-lived Li_{2}^{+}

Physical Review Research
We report on the efficient production of Li_{2}^{+} ions in a magneto-optical trap (MOT) of Li atoms prepared in an ensemble of 2S, 2P, and 3S states. A linear Paul trap surrounding the MOT is used to trap and investigate the time evolution of the ion ...

Fiscal Deficits, Debt, and Monetary Policy in a Liquidity Trap [PDF]

The macroeconomic response to the economic crisis has revived old debates about the usefulness of monetary and fiscal policy in fighting recessions. Without the ability to further lower interest rates, policy authorities in many countries have turned to ...

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

Arthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Solutions of the Mathieu–Hill Equation for a Trapped-Ion Harmonic Oscillator—A Qualitative Discussion

Mathematics
We investigate solutions of the classical Mathieu–Hill (MH) equation that characterizes the dynamics of trapped ions. The analytical model we introduce demonstrates the equations of motion are equivalent to those of a harmonic oscillator (HO).

Ion accumulation in a Paul trap for the Canadian Penning Trap Mass Spectrometer

, 1998
The Canadian Penning trap Mass Spectrometer (CPTMS) was reassembled and commissioned at Argonne National Laboratory. It consists of three systems: a laser desorption ion source, used for stable isotope production; a radio-frequency quadrupole ion trap ...

Green Entrepreneurship Research: A Review of the Domain and Future Research Agenda

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examined the evolving landscape of green entrepreneurship (GE) research through a comprehensive analysis that combined bibliometric and systematic literature reviews. Analysis of 88 articles retrieved from the Web of Science (WoS) mapped the research trajectory, identifying key authors, journals and research themes.
