Nanoparticle Immunoadjuvant Complexes Augment Germinal Center Responses to Vaccination

open access: yesAdvanced Science, EarlyView.
Scaffolding IL‐21 on the surface of a self‐assembling nanoparticle immunogen drives improved germinal center and humoral immune responses. These nanoparticle immunoadjuvant complexes (NICs) functionally modulate the germinal center driving improved somatic hypermutation and antibody maturation, suggesting this platform has potential utility as a ...

Substrate‐Selective Temperature‐Controlled Synthesis of Thiophene Derivatives at Interfaces

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
The deposition of a dithiophene derivative on Ag(111) at room temperature followed by annealing gives rise to molecular wires, whereas the adsorption of the same precursor on a hot substrate affords the formation of benzotrithiophene species. Abstract The temperature‐controlled transformation of organic molecules at interfaces is an incipient yet ...

Root lodging is a physical stress that changes gene expression from sucrose accumulation to degradation in sorghum

open access: yesBMC Plant Biology, 2018
Background Sorghum (Sorghum bicolor L.) is used as a raw material for biofuels because it accumulates sugars at high levels in the stem. Lodging of sorghum occurs when the soil is wet and very high winds blow across the field.
