The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals
A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

Bio‐Inspired Nanoarchitected LiFePO4 Cathodes
Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...

Tensile properties of in-situ precipitated polydimethylsiloxane networks
Tensile propertiesof polydimethylsiloxane (PDMS) networks filled with in-situ precipitated silica were investigated. Experimental results showed that increasing the swelling time of cured rubber sheets in tetraethoxysilane (TEOS) solution or elevating ...

Minimizing heterogeneity of sugarcane bagasse ash by silica extraction via sol gel process
This work proposes to extract silica via the sol-gel process using molecular precursors from four distinct sugarcane bagasse ashes. The process comprised cleaning, silica extraction using sodium silicate, and gel formation by lowering the solution pH ...

Chiral Nanohoops as an Efficient Spin Polarization System
Chiral conjugated nanohoops with a central dibenzopentalene unit exhibit 90% spin polarization at low voltage and high conductivity. These properties make them ideal components in molecular spintronics applications. Abstract A central challenge in molecular spintronics is to achieve a high spin polarization at low operating voltages and ambient ...
