Direct Growth of BODIPY‐Based Conjugated Porous Polymer Shell on Upconversion Nanoparticles for NIR‐Driven Photocatalysis

Small, EarlyView.
Monomer prefunctionalization of upconversion nanoparticles directs uniform growth of BODIPY‐based conjugated porous polymers shells, affording precise control over polymer loading and optimized NIR‐triggered photocatalytic activity. ABSTRACT The great applications of upconversion nanoparticles (UCNPs) can be further extended by their encapsulation ...

Hydrogen Bonding Denticity Governs Surface Modulation in Inorganic Perovskite Nanocrystals

Small, EarlyView.
Organic cations with distinct hydrogen‐bonding denticities enable systematic modulation of perovskite nanocrystal surfaces. Increasing denticity from mono‐dentate MA+ to bi‐dentate FA+ and multi‐dentate GA+ strengthens interactions with surface iodides, effectively suppressing surface defects.

Kirigami‐Inspired Deployable Microneedle Robot With Enhanced Conformability for Targeted Oral Drug Delivery

Small, EarlyView.
We have engineered a kirigami‐inspired deployable microneedle robot (KiriBot) capable of remotely controlled attachment to target tissues for sustained drug release. KiriBot incorporates a flexible structure that enhances conformability, improves adherence to irregular tissues, and facilitates microneedle insertion.

Deciphering Molecular Charge Anisotropy: The Case of Antibody Solutions

Small, EarlyView.
Molecular charge anisotropy emerges as a key determinant of antibody solution behavior. A multiscale framework combining electrostatic mapping, coarse‐grained simulations, and machine‐learning‐assisted optimization identifies charge patterns that reproduce experimental structure factors and predict collective properties across concentration, revealing ...

XMM–Newton Observations of Soft Gamma-Ray Repeaters [PDF]

Astrophysics and Space Science, 2007
All the confirmed Soft Gamma-ray Repeaters have been observed with the EPIC instrument on the XMM-Newton satellite. We review the results obtained in these observations, providing the most accurate spectra on the persistent X-ray emission in the 1-10 keV range for these objects, and discuss them in the context of the magnetar interpretation.

A Low-Magnetic-Field Soft Gamma Repeater

Science, 2010
Soft gamma repeaters (SGRs) and anomalous x-ray pulsars form a rapidly increasing group of x-ray sources exhibiting sporadic emission of short bursts. They are believed to be magnetars, that is, neutron stars powered by extreme magnetic fields, B similar
