Synchronizing Tunable Luminescence and Shape Morphing in a Metal Nanocluster–Enabled Hydrogel Platform

open access: yesAdvanced Materials, EarlyView.
A nanocluster–gel platform is developed to synchronously integrate tunable luminescence and shape morphing under a single stimulus, with emission programmability encoded through cluster size modulation (Au10 → Au18). Solvent‐induced shape–optical transitions are visualized in a lotus‐shaped gel that dynamically folds and dims, enabling rapid (< 5 s ...

Positive association between urinary levels of 8-hydroxydeoxyguanosine and the acrylamide metabolite N-acetyl-S-(propionamide)-cysteine in adolescents and young adults

open access: yes, 2014
Acrylamide is present in mainstream cigarette smoke and in some foods prepared at high temperatures. Animal studies have shown that acrylamide exposure increases oxidative stress; however, it is not known if this also occurs in humans.

Thiolated Polymers in 3D Bioprinting: Control of Gelation

open access: yesAdvanced Materials, EarlyView.
Thiolated polymers are established as programmable bioinks for 3D bioprinting, integrating versatile crosslinking chemistries with redox‐responsive control. This work demonstrates how molecular design and external triggers define gelation kinetics, printability windows, and structural fidelity, enabling stable, high‐resolution constructs and advancing ...

Relationship between alkylpyrazine and acrylamide formation in potato chips

open access: yes, 2016
Levels of acrylamide and fourteen alkylpyrazines were measured in chips made from twenty cultivars of potato, which had been stored for two and six months. While a significant correlation existed between acrylamide and total pyrazines (r 2 = 0.609; p = 0.

Engineering Strain‐Stiffening Granular Hydrogels for 3D‐Printed Tissue‐Mimicry

open access: yesAdvanced Materials, EarlyView.
A 3D‐printable strain‐stiffening double‐network granular hydrogel (SDGH) enables independent, region‐specific tuning of toe (EToe) and heel (EHeel) moduli through control of microgel packing and network composition. This platform replicates tissue‐like nonlinear mechanics and allows fabrication of high‐fidelity, multilayered aortic valves with ...

Association of acrylamide dietary intake with glycation and oxidative status biomarkers and intakes of advanced glycation end-products or alpha-dicarbonyls

open access: yesScientific Reports
Acrylamide, advanced glycation end products (AGEs), and alpha-dicarbonyls are formed during the thermal processing of foods. Their dietary intake raises potential health concerns.

Soft Hardware, Flowing Software: Reconfigurable Microfluidics for Adaptable Chemical Computation

open access: yesAdvanced Materials, EarlyView.
A reconfigurable microfluidic platform based on soft, photo‐printable, and chemically erasable hydrogel structures printed and erased in situ is used to control flow routing, mixing, chemical patterning, and even chemical computing. Using hardware to control chemical computations decouples logic function from molecular composition, demonstrated via ...

Dietary Maillard reaction products: implications for human health and disease

open access: yes, 2009
When foods are heat processed, the sugars and lipids react with the proteins they contain via the Maillard and related reactions to form a wide range of products.
