Spontaneous CP Violation [PDF]

open access: yes, 1998
In this talk I begin with some general discussion of the history of CP violation, then move on to aspects of the aspon model including the production of new particles at LHC, implications for B decay, generalized Cabibbo mixing and a reevaluation of kaon

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

open access: yesAdvanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

open access: yesAdvanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

An Inquiry into Juan Ramon's Interest in Walter Pater

open access: yesStudies in 20th & 21st Century Literature, 1983
The evidence for Juan Ramon's interest in Pater, which began around 1920 and was still active twenty years later, is discussed in this paper. Pater's view of death and dying and his attitude toward the decadent persona are described in so far as they ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

open access: yesAdvanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Boosting Seawater Desalination by Ampere‐Level Nitrate Electroreduction On Defect‐Rich Ultrathin RuCu Alloy Nanostructures

open access: yesAdvanced Materials, EarlyView.
Defect engineering of ultrathin RuCu alloy nanostructures has been successfully achieved to enhance ammonia electrosynthesis under indutrial‐level current density. Simultaneously, the stable ampere‐level operation of nitrate electroreduction on defective RuCu nanostructures can drive seawater desalination at an ultrafast salt removal rate, offering an ...

Composition Restoration Enables Recycling of Mixed‐Cation, Mixed‐Halide Perovskites for Solar Cells

open access: yesAdvanced Materials, EarlyView.
Compositional drift during processing prevents the direct recycling of mixed‐cation, mixed‐halide perovskites. This work introduces a framework to quantitatively audit and restore recovered materials, enabling closed‐loop recycling with efficiencies comparable to virgin perovskites.
