Probing the Energy Landscape of α‐Synuclein Amyloid Fibril Formation by Systematic K‐to‐Q Mutagenesis

Advanced Science, EarlyView.
We use lysine‐to‐glutamine mutations to study the effect of electrostatics on the kinetics and thermodynamics of alpha‐synuclein amyloid fibril formation. We find that mutational effects map on their structural context within fibrils and identify residues that modulate the energy landscape of alpha‐synuclein self‐assembly. Our work outlines a scalable,

Self‐Propelled HPB@Lip@AB Nanomotors Ameliorate Dry Eye Disease

Advanced Science, EarlyView.
A self‐propelled HPB@Lip@AB nanomotor system is developed for dry eye disease (DED) therapy, facilitating rapid penetration across ocular surface barriers while integrating hydrogen therapy with multi‐enzyme‐like antioxidant activity. The nanoplatform restores mitochondrial function, suppresses oxidative stress, inflammation, and apoptosis, and ...

Influence of ammonium sulfate on the corrosion behavior of AZ31 magnesium alloy in chloride environment

Journal of Magnesium and Alloys
Electrochemical corrosion of AZ31 magnesium alloy in the NH4+-SO42−-Cl− environment is studied. Effect of NH4+ overshadows that of Cl− as the (NH4)2SO4 concentration is 0.005 M or higher, yielding an evolution from localized corrosion to uniform ...

Developing Metal–Polyphenol Network‐Based Single‐Protein Particle Encapsulation System for Sustained Release of Whey Protein to Mitigate Sarcopenia

Advanced Science, EarlyView.
Sarcopenia has emerged as a major health challenge in the aging population. Developing a sustained‐release system for whey protein may enhance its effectiveness in mitigating sarcopenia. Herein, a novel “single‐protein particle encapsulation” (SPPE) system is developed to protect whey protein and control its release.

Metal–Phenolic Complexation Governs Soil Mineral Crystallinity to Enhance Crop Growth

Advanced Science, EarlyView.
A coordination‐driven, coprecipitation approach is presented to obtain polyphenolic‐incorporated minerals with tunable crystallinity, offering insights into how plants may influence soil mineral structures. Soil minerals can incorporate polyphenolic secondary metabolites and enhance plant nutrition by facilitating the formation of amorphous metal ...

Solid state transformations of (NH4, Pb)-clinoptilolite through heating

, 2018
Three clinoptilolite-based materials, having Pb2+/NH4+ ratios of 1.60, 0.56 and 0.16, were prepared starting from a powder containing ≈90% of NH4-clinoptilolite. The samples were submitted to a set of thermal treatments of 2 hours up to 1000 °C.

Soil pH Amelioration Synergizes Carbon Accrual with Yield Gains Under Organic Substitution

Advanced Science, EarlyView.
Soil pH shifts towards neutrality in both acidic and alkaline soils under organic substitution. A global synthesis links pH amelioration to soil organic carbon accrual through enhanced microbial biomass after accounting for added organic carbon and its interaction with pH. This pH amelioration‐shared soil organic carbon accrual accounts for 5.1–8.6% of

Reorientational Motions and Ionic Conductivity in (NH4)2B10H10 and (NH4)2B12H12

, 2018
We investigated molecular dynamics in two ammonium borane systems from the group of promising ion conductors. The investigation was performed by means of 1H and 11B NMR spectroscopy and spin-lattice relaxation techniques.
