Exploring the Synthesis of Metalloporphyrin Equipped Pd12L24 Supramolecular Spheres

open access: yesChemistry – A European Journal, EarlyView.
We expand the scope of Pd12L24 nanospheres equipped with porphyrins. Focusing on the porphyrin metallation state, synthetic strategies for porphyrin building block (BB)compounds are developed. The compounds are evaluated against nanosphere self‐assembly conditions.

Non‐Invasive Estimation of Systemic Drug Exposure Using Exhaled Breath Metabolomics in Humans: A Translational Proof‐of‐Concept Study

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Accurate assessment of systemic drug exposure in humans remains challenging, as conventional approaches rely on intermittent blood sampling and laboratory‐based assays that are invasive and provide limited temporal resolution. Exhaled breath contains volatile and semi‐volatile compounds arising from drug metabolism and downstream biological processes ...

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Closing the Loop in Agrivoltaics: A Radiative Cooling Coating for Synergistic Self‐Cleaning and Water Harvesting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanostructured photonic‐thermal coating enables radiative‐cooling‐induced condensation and water harvesting, establishing a self‐sustaining agrivoltaics microclimate loop that transforms PV panels into active climate regulators. The integration of photovoltaic (PV) panels into agricultural landscapes (i.e., agrivoltaics) offers a promising path for ...
