Efficient Preservation of Perishable Fruits by Erasable Metal‐Organic Frameworks

Advanced Science, EarlyView.
This study presents an erasable Pickering emulsion‐based coating stabilized by metal‐organic frameworks. This washable coating significantly extends fruit shelf life by scavenging ethylene and inhibiting foodborne pathogens, offering a sustainable solution for postharvest.

Ce‐Doped Lignin‐Based Nanozyme with Heat‐Activated Hydrolase Activity

Advanced Science, EarlyView.
A novel Ce‐doped lignin‐based hydrolase nanozyme (Ce‐AL) is synthesized using Ce ions coordinated with aminated industrial lignin. The Ce‐AL effectively hydrolyzes phosphate ester bonds and protein amide bonds, maintain high activity at 100°C, and successfully fights bacteria biofilms.

Ultrafast Dense Immobilization of Noble Metal Nanoparticles on Customizable Multifunctional Polymer Microspheres for Heterogeneous Catalysis and Multiplexed Biodetection

Advanced Science, EarlyView.
This work proposes a facile co‐assembly strategy to achieve highly uniform and dense immobilization of diverse noble metal nanoparticles onto metastable multifunctional (e.g., magnetic or fluorescent) polymer microspheres, enabling fabrication of complex hierarchical superstructures.

Building Molecules by a Self‐Replicator That Catalyzes Acyl Hydrazone Formation

Angewandte Chemie, EarlyView.
A self‐replicator efficiently catalyzes the formation of acyl hydrazone bonds between a set of different substrates. In addition to previously reported (bond‐breaking) catalytic activity, this renders the self‐replicator highly promiscuous, which is a good starting point for Darwinian experiments en route to de‐novo life.

Correlated Ground-based and IUE Observations [PDF]

The value of coordination among different observers particularly, those working in different wavelength regions is highlighted. This coordination is more important among observers of comets than among observers of almost any other class of astronomical ...

An Atlas of Spectrophotometric Landolt Standard Stars

, 2005
We present CCD observations of 102 Landolt standard stars obtained with the R-C spectrograph on the CTIO 1.5 m telescope. Using stellar atmosphere models we have extended the flux points to our six spectrophotometric secondary standards, in both the blue

Wafer Scale III‐Nitride Deep‐Ultraviolet Vertical‐Cavity Surface‐Emitting Lasers Featuring Nanometer‐Class Control of Cavity Length

Advanced Science, EarlyView.
A DUV‐VCSEL strategy featuring the nanometer‐class control of the cavity length is proposed in the DUV optoelectronic framework based on GaN templates. After the sapphire removal, a self‐terminated etching technology is developed, whereby the cavity length can be accurately determined by epitaxy instead of the fabrication process. As such, a record low
