Unfolding and Degradation of Micellar Immunodrug Carriers Derived From End Group Modified Aliphatic Poly(Carbonate)s with Acid‐Responsive Ketal Side Groups

Advanced Materials, EarlyView.
An acid‐responsive polymeric micelle system based of aliphatic poly(carbonate)s with benzyl ketal side chains is designed for targeted immunodrug delivery. It can disassemble in endosomal environments, enabling site‐specific immunoactivation and enhanced biodegradability.

Stable isotope studies [PDF]

, 1989
The research has been in four general areas: (1) correlation of isotope effects with molecular forces and molecular structures, (2) correlation of zero-point energy and its isotope effects with molecular structure and molecular forces, (3) vapor pressure isotope effects, and (4) fractionation of stable isotopes. 73 refs, 38 figs, 29 tabs.

Arresting Microphase Separation Encodes Material Mechanics by Sculpting Microarchitectures and Local Polymer Enrichment

Advanced Materials, EarlyView.
Microarchitecture sculpting via phase separation programs hydrogel mechanics by creating globular, inverse globular, and spinodal structures. Spinodal architectures deliver superior toughness and energy dissipation, while ionic modulation through single polymer phase separation offers a simple, scalable route to tune mechanical properties ...

Investigating the effects of animal-specific δ15N-NH3 values volatilized from livestock waste on regional NH3 source partitioning

Atmospheric Environment: X
The natural 15N abundance of ammonia (δ15N-NH3) emitted from livestock waste within a specific area (δ15N-NH3-LW) can be used to estimate its contribution to atmospheric NH3 through an isotope mixing model. However, the limited availability of reports on

Electrochemical Carbon Dioxide Reduction to Methanol on Copper‐Based Catalysts: Mechanistic Insights and Industrial Prospects

Advanced Materials, EarlyView.
This review presents a focused and integrated perspective on copper‐based catalysts for the selective electrochemical reduction of CO2 to methanol. It elucidates active site dynamics, mechanistic pathways, and structure–activity relationships, while connecting fundamental insights with catalyst design, reactor engineering, and techno‐economic ...

Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions

Advanced Materials, EarlyView.
Using multimodal operando spectromicroscopy, the frustrated phase transition responsible for selective oxidation over cobalt oxide spinel catalysts is identified, corresponding to combined surface reaction and Mars‐van Krevelen (MvK) dynamics. This regime is disrupted by the formation of mobile vacancies and the depletion of active oxygen at high ...

Habitat-based variation in the trophic ecology of the world’s highest-altitude self-sustaining population of invasive rainbow trout

Knowledge and Management of Aquatic Ecosystems
Rainbow trout (Oncorhynchus mykiss) have been widely introduced outside of their natural range and are one of the World’s most invasive species. Illegally introduced into the isolated, high-altitude (4520 m) Chungará catchment of northern Chile, rainbow ...
