Food aroma compounds by Capillary Electrophoresis

open access: yes, 2019
The concept of aroma includes all the volatile substances responsible for odors, in terms of key odorants, but also of off-flavors, developed during food processing and storage, and derived from degradation, oxidation or fermentation reactions.

3D Printing Innovations in Polymeric Porous and Patterned Architecture

open access: yesAdvanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Synthesis of wine aroma compounds: precursors and labelled standards

open access: yes, 2023
Pinot noir is one of the oldest wine cultivars, which has quickly grown to become the second most important variety among red grapes in New Zealand. By expanding our understanding of which compounds contribute to the Pinot Noir’s wine aroma and how ...

Facile Preparation of Carbon Membranes Derived from a Fluorenyl‐Containing Polyimine for Selective Hydrogen Separation

open access: yesAdvanced Functional Materials, EarlyView.
A fluorenyl‐containing polyimine is introduced as a simple, scalable precursor for high‐performance carbon membranes. The precursor's intrinsic kinked structure enables defect‐free membrane formation with enhanced hydrogen permeance and excellent ideal selectivities for key industrial gas pairs (H2/N2, H2/CH4, and H2/CO2), offering a practical route ...

Aroma Potential of German Riesling Winegrapes during Late-Stage Ripening

open access: yesBeverages
The “aromatic maturity” of winegrapes is not fully understood, particularly during the later stages of ripening. The contribution of grapes to wine aroma has historically been challenging to determine, given most aroma compounds originate from ...

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...

Tailoring Li‐ion Storage and Transport in Two‐Dimensional Conjugated Metal‐Organic Frameworks via Precise Nitrogen Incorporation

open access: yesAdvanced Functional Materials, EarlyView.
Two nitrogen‐doped 2D conjugated metal‐organic frameworks (2D c‐MOFs, namely Cu‐Nx‐OHBA, x = 2 or 4) are synthesized, featuring precise nitrogen incorporation via rational ligand design. The Cu‐Nx‐OHBA 2D c‐MOFs are largely tailorable by varying skeletal nitrogen density, with respect to electrical conductivity, Li‐storage capacitance, and Li‐transport

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.
