Crystallization of Polymers with a Reduced Density of Entanglements

open access: yesCrystals
Since methods for reducing macromolecule entanglements have been developed, it has become possible to better understand the impact of polymer chain entanglement on the crystallization process.

Emergent Magnetism, Heavy Electrons, and Pressure‐Induced Reentrant Superconductivity in the Iron Substituted 4d Transition‐Metal Sulfides

open access: yesAdvanced Science, EarlyView.
This work illustrates that magnetic Fe substitution enables systematic modulation of physical properties of the putative unconventional superconductor Rh17S15. Iron doping uncovers delicate competition between weak ferromagnetism, spin‐glass states, heavy‐fermion signatures, and superconductivity.

DYNAMIC SIMULATION OF A NON-ISOTHERMAL MSMPR CRYSTALLIZER

open access: yesChemical Engineering Communications, 1984
The effect of including temperature variations in the dynamic simulation of an MSMPR cooling crystallizer is investigated. Power law nucleation and growth kinetic models incorporating an Arrhenius temperature dependence are used. The effects of changes in the input variables feed temperature, feed flowrate and feed concentration on the output variables

Programmable Guest‐Induced 5‐Phase‐Transition Topological Reconstructions of Cobalt Formate Metal–Organic Frameworks

open access: yesAdvanced Science, EarlyView.
A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.

Sn‐Driven Grain Boundary Elimination for Single‐Crystalline Ni‐Rich Cathodes with Superior High‐Voltage Stability in Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
A low‐temperature synthesis method of single‐crystalline NCA was successfully achieved by Sn doping, employing the same synthetic conditions as its polycrystalline counterparts. This synthesis was conducted at a temperature that was 150 °C lower than that required for synthesizing single‐crystalline NCA without Sn doping.

Nonlinear Quantum Effects Drive Grotthuss Proton Conduction in Structured Electrolytes Based on Deep Eutectic Solvents

open access: yesAdvanced Science, EarlyView.
We demonstrate that the inverse relationship between viscosity and conductivity in structured electrolytes can be circumvented by leveraging their hydrogen bonding networks for Grotthuss proton transport. Using a mixture of imidazole and levulinic acid, we show that the existence of extended hydrogen‐bonded chains that can rapidly reorient result in ...

Tailoring Electronic Structure of NbB2 Nanorods Through Selenium Incorporation for Synergistically Enhanced Hydrogen Evolution and Triboelectric Energy Harvesting

open access: yesAdvanced Science, EarlyView.
Selenium incorporation modulates the electronic structure of niobium diboride (Se‐NbB2) nanorods, enhancing the active site density and resulting in superior hydrogen evolution performance for sustainable energy applications. ABSTRACT The sluggish hydrogen evolution reaction (HER) kinetics of non‐noble‐metal catalysts remain a major challenge for ...

Non-isothermal crystallization kinetics of plasticized poly(Lactic-acid) nanocomposites

open access: yes, 2020
Non-isothermal crystallization kinetics of poly(lactic acid) (PLA) composites consisting of hemp fiber and nanosilica plasticized with tributyl citrate (TBC) was studied by differential scanning calorimetry (DSC) at various scanning rate.
