Published: June 2014

We demonstrate the use of a phase-only spatial light modulator for the measurement of transverse spatial distributions of coincidence counts between twin photon beams, in a fully automated fashion. This is accomplished by means of the polarization dependence of the modulator, which allows the conversion of a phase pattern into an amplitude pattern. We also present a correction procedure, that accounts for unwanted coincidence counts due to polarization decoherence effects.

We present the synthesis, structural analysis, and remarkable reactivity of the first carbon nanohoop that fully incorporates ferrocene in the macrocyclic backbone. The high strain imposed on the ferrocene by the curved nanohoop structure enables unprecedented photochemical reactivity of this otherwise photochemically inert metallocene complex. Visible light activation triggers a ring-opening of the nanohoop structure, fully dissociating the Fe-cyclopentadienyl bonds in the presence of 1,10-phenanthroline.

Development of national post-fire restoration system to assess net GHG impacts and salvage biomass availability.

In light of the recent unprecedented wildfires in Canada and the potential for increasing burned areas in the future, there is a need to explore post-fire salvage harvest and restoration and the implications for greenhouse gas (GHG) emissions. Salvage logging and replanting initiatives offer a potential solution by regrowing forests more quickly while meeting societal demands for wood and bioenergy. This study presents a comprehensive modeling framework to estimate post-fire salvage biomass and net GHG emissions relative to a 'do-nothing' baseline for all of Canada's harvest-eligible forests.

Polariton lattices as binarized neuromorphic networks.

Spin-Optics laboratory, St. Petersburg State University, St. Petersburg, 198504, Russia.

We introduce a novel neuromorphic network architecture based on a lattice of exciton-polariton condensates, intricately interconnected and energized through nonresonant optical pumping. The network employs a binary framework, where each neuron, facilitated by the spatial coherence of pairwise coupled condensates, performs binary operations. This coherence, emerging from the ballistic propagation of polaritons, ensures efficient, network-wide communication.

Transmission electron microscopy, especially at cryogenic temperature, is largely used for studying biological macromolecular complexes. A main difficulty of TEM imaging of biological samples is the weak amplitude contrasts due to electron diffusion on light elements that compose biological organisms. Achieving high-resolution reconstructions implies therefore the acquisition of a huge number of TEM micrographs followed by a time-consuming image analysis.

Oxygen, light, and mechanical force mediated radical polymerization toward precision polymer synthesis.

Chem Commun (Camb)

State Key Laboratory of Molecular Engineering of Polymers, Department of Macromolecular Science, Fudan University, Shanghai 200438, China.

The synthesis of polymers with well-defined composition, architecture, and functionality has long been a focal area of research in the field of polymer chemistry. The advancement of controlled radical polymerization (CRP) has facilitated the synthesis of precise polymers, which are endowed with new properties and functionalities, thereby exhibiting a wide range of applications. However, radical polymerization faces several challenges, such as oxygen intolerance, and common thermal initiation methods may lead to side reactions and depolymerization.
