Olefin Polymerizations Oriented by Rational Designs of Group-13 Compounds. [PDF]

Chem Rec
In coordination olefin polymerization chemistry, boron and aluminum compounds play important roles in both catalyst components and monomers. This personal account introduces our recent progress on the development of catalyst systems featured by the design of group‐13 counteranions, as well as the application of boronic acid‐crosslinked polyolefins to ...

Large‐Scale In Situ Formation Perovskite Quantum Dots/Elastomer Composite for High‐Performance White Light‐Emitting Diodes

Advanced Science, EarlyView.
A solvent‐free, open‐mill shear protocol nucleates 2.6 nm CsPbBr3 QDs uniformly within brominated butyl rubber. The emitters showed 91% PLQY, 1189 ns lifetime, and > 90% retention after 30‐day ambient storage and water immersion, respectively. Board‐to‐board forms 17 × 17 cm2 flexible films for 132% NTSC white LEDs, scintillators, and stretchable ...

Methanol and isoprene emissions from the fast growing tropical pioneer species Vismia guianensis (Aubl.) Pers. (Hypericaceae) in the central Amazon forest [PDF]

Atmospheric Chemistry and Physics, 2016
Isoprene (Is) emissions by plants represent a loss of carbon and energy resources leading to the initial hypothesis that fast growing pioneer species in secondary tropical forests allocate carbon primarily to growth at the expense of isoprenoid ...

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Flexible organic room‐temperature phosphorescent materials

FlexMat, EarlyView.
This review highlights recent advances in flexible organic room‐temperature phosphorescent (RTP) materials, covering both organic crystal and polymer systems. It discusses strategies to overcome the inherent rigidity and enhance the mechanical flexibility of organic RTP materials, aiming to enable their practical applications in anti‐counterfeiting ...

Diterpenoid Diversity across Land Plants

Helvetica Chimica Acta, EarlyView.
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

Geranyl Diphosphate Synthase (CrtE) Inhibition Using Alendronate Enhances Isoprene Production in Recombinant Synechococcus elongatus UTEX 2973: A Step towards Isoprene Biorefinery

Fermentation, 2023
A hemiterpene, isoprene, is commercially produced from crude oil refining processes. As a result of fossil fuel depletion, isoprene production process development is gaining attention from recombinant cyanobacteria and other microbial systems for its ...

Post‐Additional Proteins into Rubber Matrices Behave as Filler to Reinforce Rubber

Macromolecular Materials and Engineering, EarlyView.
The post‐additional proteins exhibit a reinforcement effect regardless of the origin of the rubber. The proteins are lyophilized to obtain a powder, which is then incorporated into the rubber matrices using a solution‐mixing process. These findings suggest that protein can function as a reinforcing filler depending on the rubber preparation process ...

Isoprene-Emitting Tobacco Plants Are Less Affected by Moderate Water Deficit under Future Climate Change Scenario and Show Adjustments of Stress-Related Proteins in Actual Climate

Plants, 2023
Isoprene-emitting plants are better protected against thermal and oxidative stresses, which is a desirable trait in a climate-changing (drier and warmer) world.

Latex Serum‐Derived Supramolecular Networks Enable Toughening of Natural Rubber

Macromolecular Rapid Communications, EarlyView.
Latex‐serum addition enhances strain‐induced crystallization (SIC) toughening in natural rubber, increasing tearing strength and extending the SIC activation window. Supramolecular networks form via bifurcated hydrogen bonding between polyol components (e.g., quebrachitol) and end‐functionalized polyisoprene chains, serving as effective crystallization
