Plasmonic Effect of Au Nanoparticles Deposited onto TiO₂-Impact on the Photocatalytic Conversion of Acetaldehyde

Molecules
A comparison of two synthesis methods for depositing Au nanoparticles onto TiO2 was performed: (1) impregnation with HAuCl4 followed by thermal treatment in argon, and (2) magnetron sputtering from a Au disc.

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

European Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Derivation and Validation of a Predictive Model for Advanced Colorectal Neoplasia Among Average‐Risk Adults in China

International Journal of Cancer, EarlyView.
Efficient pre‐colonoscopy risk stratification tools are needed, especially in China. Using multicenter colorectal cancer screening data from Shandong Province, the authors developed and validated a risk prediction model for advanced colorectal neoplasia in asymptomatic individuals using sociodemographic characteristics, lifestyle factors, and medical ...

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

Macromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...

LowCOST‐HSQC Variants for Fast‐Pulsing High ω1$$ {\omega}_1 $$‐Resolved 2D Experiments

Magnetic Resonance in Chemistry, EarlyView.
The LowCOST‐HSQC is a sensitivity‐enhanced HSQC version that retains unused proton polarization for subsequent scans in correlations to low natural abundance nuclei like 13$$ {}^{13} $$C or 15$$ {}^{15} $$N. Together with fast polarization distribution via isotropic mixing, it allows the acquisition of fast‐pulsing 2D experiments.
