PERFECTA Loaded Lipid Cubosomes for 19F‐MRI: Physico‐Chemical Characterization

Chemistry – A European Journal, EarlyView.
Phytantriol‐based cubosomes loaded with PERFCTA, a fluorinated MRI probe, were developed as promising systems for imaging and drug delivery. The nanoparticles showed high PERFECTA encapsulation efficiency, strong fluorine MRI signals, and optimal colloidal stability in biological media.

Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

From Mn(II)3 to Mn(IV)3: Controlled Multielectron Oxidation and Hydrocarbon Oxygenation Within a 7‐Dipy Trinuclear Scaffold

Journal of the Chinese Chemical Society, EarlyView.
A trinuclear manganese complex supported by the 7‐Dipy scaffold undergoes controlled multielectron oxidation from Mn(II)3 to high‐valent Mn(IV)3 states. Spectroscopic signatures, including 16‐line and geff ≈ 5 EPR features, reveal stepwise redox accumulation. The oxidized Mn3 cluster mediates efficient oxygen‐atom transfer to strong CH bonds, enabling

Enabling Quantitative Benchtop 13C NMR Spectroscopy in Fast Continuous Flow

Magnetic Resonance in Chemistry, EarlyView.
Paramagnetic relaxation enhancement (PRE) accelerates polarization buildup in continuous‐flow benchtop 13$$ {}^{13} $$C NMR spectroscopy by the use of an immobilized PRE agent. By combining PRE with PENDANT polarization transfer, weak 13$$ {}^{13} $$C signals are enhanced even at high flow rates, enabling robust quantitative analysis of solvent ...

A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.

Synthesis and Characterization of Acrylate‐Based Block and Block‐Graft Copolymers Using Polyester‐Based Macro‐RAFT Agents Through Two‐Step Polymerization and Assessment of One‐Pot Epoxy Group Ring‐Opening Modification

Polymer Engineering &Science, EarlyView.
Schematic diagram of RAFT polymerization of acrylate monomers. ABSTRACT This study reports the synthesis of a macro‐RAFT agent based on poly(ɛ‐caprolactone) (PCL) via ring‐opening polymerization (ROP), which was subsequently used to prepare acrylate‐based block and block‐graft copolymers through RAFT polymerization.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

An Inimer Approach Based on Photo Iniferter RAFT Polymerization Toward One‐Pot Bottlebrush Copolymers Featuring Grafts From Less Activated Monomers

Journal of Polymer Science, EarlyView.
We present a stepwise one‐pot synthesis of bottlebrush copolymers using the inimer approach for less activated monomers (LAMs). Under the irradiation of wavelength 1 (λ1), an acrylamide‐based inimer was polymerized to create a backbone with active sites for grafting.
