Characterization of Melt-functionalized Polyolefins

open access: yes
Polyolefins account for nearly 50% of global plastic production and are recycled at a rate of 1-10%. Functionalization and upcycling of waste polyolefins through incorporating polar functional groups is a promising method for turning polymer waste into ...

Optical Durability of Contemporary PV Encapsulants Through Artificial UV Weathering

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Encapsulant choice can be used to mitigate UV‐induced degradation in modern silicon photovoltaic modules, but this strategy is only effective if encapsulants are durable under UV weathering. This study identifies optical changes to 14 commercial encapsulants as a function of UV weathering and identifies that, while changes to material transmittance ...

Impact of Commercial Polyolefin Architecture and Composition on Its Ability to Compatibilize High‐Density Polyethylene/Isotactic Polypropylene Blends

open access: yesJournal of Polymer Science, EarlyView.
This research elucidates the relationship between the molecular structure of commercially available ethylene–propylene copolymers and an ethylene/1‐olefin copolymer and its ability to compatibilize high‐density polyethylene/isotactic polypropylene blends. These findings indicate that the compatibilization of these blends with random copolymers benefits

Exploiting Device Deformability for Fluid and Particle Manipulation

open access: yesSmall, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Phosphorous removal from water by polyolefins: effect of Al2O3 addition

open access: yes, 2008
Phosphorus is the main nutrient responsible for eutrophication of aquatic ecosystems, therefore it is important to develop new processes to remove phosphorus that avoid the formation of precipitates.

Polysulfide Immobilization and Sulfur Conversion Kinetics Promotion via a Tetrathiafulvalene–Crown Ether COF@Graphene Layer for High‐Rate Lithium–Sulfur Batteries

open access: yesSmall, EarlyView.
A polysulfide‐regulating covalent organic framework (TUS‐44) integrating tetrathiafulvalene and crown‐ether linkers forms an electron‐delocalized, ion‐coordinative network that synergistically mediates Li–S redox chemistry. When interfaced with graphene, the TUS‐44@G layer functions as a catalytic and chemisorptive interface, enabling efficient ...

High Throughput Discovery of Grotthuss‐Type Lithium‐Ion Transport Mechanism in Metallosalen Covalent Organic Frameworks

open access: yesTransformative Chemistry, EarlyView.
Through a high‐throughput simulation of 3141 COF/lithium salt systems, we reveal that reducing framework weight universally enhances ionic conductivity. Key to performance is the matching of pore chemistry with specific anions; notably, we discover an anion‐driven “shuttle” cooperative transport mechanism, which proposes new principles for designing ...

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

open access: yesThe Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...
