Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

Advanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

XRISM Observations of the Prototypical Cold Front in A3667

The Astrophysical Journal Letters
We present high-resolution X-ray spectroscopy of the merging galaxy cluster A3667 with XRISM/Resolve. Two observations, targeting the cluster X-ray core and the prototypical cold front, were performed with exposures of 105 and 276 ks, respectively.

Numerical simulation of mesoscale structures in the northern alpine foreland during front passages: A precipitating cold front without pre-frontal foehn

Meteorologische Zeitschrift, 1993
Supplementing a previous study of a dry cold front with pre-frontal foehn (Heimann 1992c) this paper documents the numerical simulation of a precipitating cold front approaching the Alps from northwest without pre-frontal foehn.

Mechanoluminescent HOF Nanotransducers Enabled Sono‐Optogenetics in Parkinsonian Rats

Advanced Functional Materials, EarlyView.
We present a mechanoluminescent system utilizing porous hydrogen‐bonded organic frameworks (HOFs) as a toolkit for focused ultrasound‐triggered, non‐invasive light delivery to the deep brain in rats. This approach enables the specific activation of PV‐GPe neurons in dopamine‐depleted Parkinson's disease rat models, resulting in a comparable alleviation

Wave–Tide–Surge Interaction Modulates Storm Waves in the Bohai Sea

Journal of Marine Science and Engineering
Typhoons, extratropical cyclones, and cold fronts cause strong winds leading to storm surges and waves in the Bohai Sea. A wave–flow coupled numerical model is established for storm events observed in 2022 caused by three weather systems, to investigate ...

Interaction of a cold front with a sea-breeze front Observations [PDF]

Tellus A: Dynamic Meteorology and Oceanography, 1995
On 9 May 1989, during the field experiment FRONTEX, a synoptic-scale cold front was observed which moved from the North Sea to Northern Germany and interacted with a sea-breeze front. The modification of the cold front is documented by satellite images and measurements over the sea, at the coast and further inland.
