Hierarchically Engineered Multi‐Enzyme Nanoreactors for in vitro Drug Biosynthesis and Pathway Transplantation Into Cells

open access: yesAdvanced Materials, EarlyView.
A hierarchically structured metal–organic framework (eMIL) is shown to host the complete six‐enzyme biosynthesis pathway for the anti‐cancer pigment violacein, reshaping reaction dynamics and multiplying in vitro yields. eMIL nanoreactors deliver this reconstituted bacterial multi‐protein system into mammalian cells, where cell‐derived substrates and ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

open access: yesAdvanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Backbone Engineering of Carbon‐Centered NHC‐Derived Diradicals: From Electronic State Tuning to High‐Performance Organic Field‐Effect Transistors

open access: yesAdvanced Materials, EarlyView.
The open‐shell nature of diradicals facilitates charge separation, and compounds with moderate diradical character demonstrate remarkable potential in organic field‐effect transistors (OFET) applications due to their low reorganization energies for hole and electron transport.

A Comparative Study on Early‐Stage Icing Evaluation Techniques for Passive Ice Protection Systems

open access: yesAdvanced Materials Interfaces, EarlyView.
This study addresses the lack of standardized methodologies for evaluating the early‐stage icing performance of passive ice protection systems. A unified experimental protocol is proposed and applied to representative hydrophilic and hydrophobic surfaces under controlled conditions.

Interregional interactions and population mobility [PDF]

open access: possibleJournal of Economic Behavior & Organization, 2004
The institutional level at which policies should be determined is an important issue that has been extensively treated in the economics literature. In particular, the literature has discussed to what extent decentralization of policy decisions give an inefficient outcome.

Populism and mobilization

2017
Abstract There are three different types of populist mobilization: personalist leadership, social movement, and political party, although some populist actors have aspects of two or three. Personalist leadership is more prevalent in certain regions, such as Latin America. Social movements are more common in America, and political parties

Evacuation as Population Mobility

International Journal of Mass Emergencies & Disasters, 1983
An analytical perspective is used to examine the relationship of human evacuation and migration. The first part of the paper focuses on the variables of distance, permanence and voluntarism used to distinguish evacaution from migration, to point out that the lack of interest in evacuation by students of migration, partly on the basis of the assumed ...
