How the Carrier Mobility and Seebeck Coefficient of Doped Semiconducting Polymers Are Controlled by Counterion Interactions and Mesoscale Order

open access: yesAdvanced Functional Materials, EarlyView.
Conventional doping of P3HT with F4TCNQ results in poor charge transport. However, when F4TCNQ is exchanged with LiTFSI, the transport characteristics are greatly enhanced. We find the increase in charge transport is directly related to an increase in the mesoscale ordering of P3HT, resulting in longer and better‐connected transport pathways.

Understanding the welfare implications of preferential trade agreements [PDF]

open access: yes, 1999
This paper examines various implications of Preferential Trade Agreements (PTAs), namely Customs Unions (CUs) and Free Trade Areas (FTAs), in the context of a multi-country general equilibrium model based on comparative advantage considerations.

Cyclic Olefin Copolymers as Versatile Materials for Advanced Engineering Applications

open access: yesAdvanced Functional Materials, EarlyView.
Cyclic olefin copolymers (COCs) are presented as highly versatile materials combining tunable synthesis, excellent optical properties, and mechanical robustness. Their potential spans microfluidics, bioengineering, and advanced electronics, while emerging self‐healing and sustainable solutions highlight future opportunities.

Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Light‐Actuated Fiber‐Climbing Inchworm Robot Toward Endoluminal Navigation

open access: yesAdvanced Functional Materials, EarlyView.
A kirigami‐inspired soft inchworm robot harnesses optical energy from a customized side‐emitting optical fiber, guaranteeing its propulsion along the fiber body. The wavelength‐selective responsiveness of dye‐functionalized liquid crystal elastomers and the application of temporal illumination patterns enable sequential control of robot components. The

The impact of North-South and South-South trade agreements on bilateral trade. [PDF]

open access: yes
Free trade agreements (FTAs) lead to a rise in bilateral trade even if the signatories include developing countries. Furthermore, the percentage increase in bilateral trade is higher for South-South agreements than for North-South agreements. the results

Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation

open access: yesAdvanced Functional Materials, EarlyView.
A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.

The endogenous formation of sustanaible trade agreements [PDF]

open access: yes
This paper addresses the endogenous formation of trade agreements in a three - country model of imperfect competition. While the requirement of sustainability of preferential trade areas has often been ignored in the literature, I construct a framework ...
