Molecular Engineering of Polytriphenylamine: A Fluorinated Cathode for High‐Voltage, Ultrafast, and Stable Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Fluorination of polytriphenylamine lowers the HOMO energy, enabling high‐voltage operation of the PFTPA cathode. Electron‐withdrawing F substituents stabilize the nitrogen redox center and suppress polarization, leading to fast kinetics. The optimized polymer delivers ∼3.75 V vs.

Oxygen‐Tolerant Photo‐Induced Miniaturized Accelerated Atom Transfer Radical Polymerization (OPTIMA‐ATRP) for High‐Throughput Synthesis of Polymer Bioconjugates

open access: yesAngewandte Chemie, EarlyView.
Oxygen‐tolerant photo‐induced miniaturized accelerated atom transfer radical polymerization (OPTIMA‐ATRP) in water was developed for the polymerization of hydrophilic (meth)acrylate monomers under ambient or sub‐ambient (4°C) temperature and atmospheric conditions, without prior degassing, in less than 10 min, at an ultra‐small scale (< 50 µL) in ...

Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus

open access: yesAIChE Journal, EarlyView.
Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).

Enhanced Formation of Dicarboxylic Acids in the Catalytic Oxidation of Polyethylene With O2 and NOx

open access: yesAngewandte Chemie, EarlyView.
The oxidation of polyethylene in the presence of a mixture of O2 and NOx and with Cu2+/V5+ as catalyst yields ∼51 mol% diacids, while retaining ∼80 mol% of the carbon in the oil fraction. The developed method is robust and tolerates several polymer types as well as impurities.

Grain yield and protein concentration relationships in rice

open access: yesCrop and Environment
Grain protein concentration (GPC) is an important aspect of rice grain quality, which contributes to nutritional intake requirements; however, high GPC may also reduce eating quality.

Robot‐Assisted Measurement of the Critical Micelle Concentration

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.

Inverse Vulcanization Through Epoxide Chemistry: A Low Temperature Non‐Olefin Route to Sulfur‐Rich Polymer Networks

open access: yesAngewandte Chemie, EarlyView.
Epoxide monomers undergo base‐catalyzed ring‐opening copolymerization with elemental sulfur to afford sulfur‐rich polymers under mild conditions. The resulting materials exhibit excellent mechanical performance, strong adhesion (up to 10 MPa on stainless steel), and outstanding reprocessability.

A Global Prospective Harmonization Framework for Suicidality, Anhedonia, and Obsessive‐Compulsive Symptoms in Psychiatric Genetic Studies: A Cross‐Continental Study Within the Ancestral Population Network

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT This study aims to prospectively collect harmonized, quantitative, and dimensional psychiatric phenotypes (suicidality, anhedonia, and obsessive‐compulsive symptoms) and information on discrimination, stigma, and unfair treatment in up to 27,500 individuals across diverse ancestries and clinical populations for genetic analysis within the NIMH

Das fehlende Glied der Ferrocenophan‐Chemie: Isolierung eines Carba[1]Ferrocenophans

open access: yesAngewandte Chemie, EarlyView.
Die Synthese und Isolierung eines kristallinen Carba[1]Ferrocenophans wird berichtet. Ein einzelnes Kohlenstoffatom ist das bislang kleinste Verbrückungsmotiv, das in ein Ferrocenophan eingebaut werden konnte. Dies resultiert in einem Diederwinkel der Ebenen der Cyclopentadienylringe von 36.7°, was entsprechend die größte Abwinkelung relativ zu ...
