Investigating the Stress–Strain Behavior in Ring-Opening Metathesis Polymerization-Based Brush Elastomers

Here, we show that brush elastomers made by ring-opening metathesis polymerization (ROMP) of norbornene-terminated poly(dimethylsiloxane) macromonomers are less extensible than brush elastomers with the methacrylate backbone yet not as extensible (λmax) as predicted by the strain-stiffening parameter (β) derived from fitting the experimental stress–strain curves.

Taking phototherapeutics from concept to clinical launch

This Review highlights these recent discoveries, along with their limitations and clinical opportunities.

Resolving the Molecular Origin of Mechanical Relaxations in Donor–Acceptor Polymer Semiconductors

This study uses dynamic mechanical analysis (DMA) to probe thermal relaxations of a systematic set of polymers based around the benzodithiophene (BDT) moiety.

Accessing Photoredox Transformations with an Iron(III) Photosensitizer and Green Light

Efficient excited-state electron transfer between an iron(III) photosensitizer and organic electron donors was realized with green light irradiation.

From disposable diapers to adhesives

Now, poly(acrylic acid) from diaper waste has been converted into valuable pressure-sensitive adhesives through an open-loop recycling method that is cost-effective and environmentally competitive.

Inositol polyphosphates and target of rapamycin kinase signalling govern photosystem II protein phosphorylation and photosynthetic function under light stress in Chlamydomonas

We used an in vivo assay for TOR activity together with global proteomic and phosphoproteomic analyses to assess differences between wild-type and vip1-1 in the presence and absence of rapamycin.

Coherent control of asymmetric spintronic terahertz emission from two-dimensional hybrid metal halides

Here we report the observation of asymmetric spintronic-THz radiation in Two-Dimensional Hybrid Metal Halides (2D-HMH) interfaced with a ferromagnetic metal, produced by ultrafast spin current under femtosecond laser excitation.

Stereospecific Nickel-Catalyzed Reductive Cross-Coupling of Alkyl Tosylate and Allyl Alcohol Electrophiles

Herein, we report a nickel-catalyzed reductive coupling of allyl alcohols with chiral, nonracemic alkyl tosylates.

Image-guided selection of Gd@C-dots as sensitizers to improve radiotherapy of non-small cell lung cancer

In this work, two Gd@C-dots formulations were fabricated which bore carboxylic acid (CA-Gd@C-dots) or amino group (pPD-Gd@C-dots), respectively, on the carbon shell.

Seasonal Contribution of Isoprene-Derived Organosulfates to Total Water-Soluble Fine Particulate Organic Sulfur in the United States

In this work, iOSs were quantitively characterized in PM2.5 collected from 20 ground sites within the Interagency Monitoring of Protected Visual Environments (IMPROVE) network during the 2016 summer and winter seasons.

Anodic coulometry of zero-valent iron nanoparticles

Herein, this work is focused on applying the electrochemical method known as anodic particle coulometry (APC) to detect and characterize nZVI.

The Role of Oxygen in the Voltaic Pile

Here, we demonstrate that the oxygen reduction reaction (ORR) contributes to the cathodic half-reaction from pH 0 to 14, suggesting that the true mechanism of the voltaic pile depends on the mixed potential set by the HER/ORR and zinc oxidation.
