Herewith, we propose a comprehensive study of the vibrational response of chemical doping of free-standing graphene (Gr). Complementary insights on the increased metallicity have been demonstrated by the emerging plasmon excitation in the upper Dirac cone, observed by inelastic electron scattering and core-level photoemission. The electron migration in the π* upper Dirac band unveils an electron-phonon coupling of contaminant-free K-doped Gr, as evidenced by advanced micro-Raman spectroscopy in ultrahigh vacuum ambient.

Polypharmacy regimens (five or more drugs) are highly prone to unacknowledged prescribing errors, since the complex network of drug-drug interactions, guidelines and contraindications is challenging to be adequately evaluated in the prescription phase, especially if different doctors are involved. Clinical decision support systems aimed at polypharmacy evaluation may be crucial to recognize and correct prescribing errors.

- - Hydrogen is a strong alternative fuel with benefits like high energy density and low environmental impact, but its storage for cars is challenging.
- - A new method using a layered structure made of reduced graphene oxide and organosilica can host tiny MgH nanoparticles, improving their hydrogen storage capabilities compared to bulk MgH.
- - The study shows that this approach allows hydrogen to be released at lower temperatures and maintains stable performance over multiple cycles, suggesting that this method can enhance both hydrogen release and recharging efficiency.
Article Synopsis
- Electrification is crucial for reducing greenhouse gas emissions and combating climate change, but many sectors like aviation, heavy-duty transport, and chemicals will still rely on carbon.
- The Roadmap highlights multidisciplinary strategies to create a circular economy by finding alternatives to carbon and enhancing carbon reuse through advanced separation technologies.
- Emphasizing collaboration and applied scientific research is key to achieving significant reductions in greenhouse gas emissions.
Mercury pollution poses a global health threat due to its high toxicity, especially in seafood where it accumulates through various pathways. Developing effective and affordable technologies for mercury removal from water is crucial. Adsorption stands out as a promising method, but creating low-cost materials with high selectivity and capacity for mercury adsorption is challenging.
