“Writing” Crystal Phases in Amorphous Calcium Carbonate via Laser‐Induced Patterned Transformations
Advanced Functional Materials, EarlyView.Laser‐induced crystallization enabling the patterning of amorphous calcium carbonate into various distinct phases is introduced. This approach provides spatial control over polymorph selection, both crystalline and amorphous, inspired by biomineralization pathways.

Identification of a Simplest Hypervalent Hydrogen Fluoride Anion in Solid Argon
Scientific Reports, 2017 Hypervalent molecules are one of the exceptions to the octet rule. Bonding in most hypervalent molecules is well rationalized by the Rundle–Pimentel model (three-center four-electron bond), and high ionic bonding between the ligands and the central atom ...

A new ordering parameter of spectral energy distributions from synchrotron-self-Compton emitting blazars [PDF]
, 2011 The broadband SEDs of blazars exhibit two broad spectral components, which in leptonic emission models are attributed to synchrotron radiation and synchrotron self-Compton (SSC) radiation of relativistic electrons. During high state phases, the high-frequency SSC component often dominates the low-frequency synchrotron component, implying that the ...

Advanced Materials, EarlyView.The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Advanced Materials, EarlyView.This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

The Spin Contribution to the Synchrotron Light [PDF]
arXiv, 2012 In order to detect the spin contribution to the synchrotron radiation, the so-called spin light, we propose to compare the characteristics of the radiation emitted by a spin-less charged particle with the huge crop of data regarding the synchrotron light, i.e. the radiation emitted by a particle endowed with a magnetic moment.

Iodine‐Doped Sodium Vanadate Cathode for Improved Zn Ion Diffusion Kinetics
Advanced Materials, EarlyView.An iodine‐doping strategy is developed to modify the Na2V6O16·3H2O cathode for aqueous zinc‐ion batteries, effectively reducing the electrostatic interaction between zinc ions and the host structure. This modification enables faster diffusion and higher storage capacity of zinc ions. Abstract The electrostatic interaction between zinc ions and the host
