European railway reforms and efficiency: Review of evidence in the literature

Review of Economic Perspectives, 2017
The objective of the European railway reforms which started in the 1990s was to enable the entry of competition to raise the efficiency of railway transport. This was undertaken because the level of services, particularly in former Eastern Bloc countries,

Negative polarity of phenyl-C61 butyric acid methyl ester adjacent to donor macromolecule domains [PDF]

Applied Physics Letters, 2015
Interfacial fields within organic photovoltaics influence the movement of free charge carriers, including exciton dissociation and recombination. Open circuit voltage (Voc) can also be dependent on the interfacial fields, in the event that they modulate the energy gap between donor HOMO and acceptor LUMO. A rise in the vacuum level of the acceptor will

Neuromorphic Motor Control with Electrolyte‐Gated Organic Synaptic Transistors

Advanced Electronic Materials, EarlyView.
Electrolyte‐gated organic synaptic transistor (EGOST)‐based neuromorphic motor control systems integrate sensing, processing, and actuation by mimicking biological synapses. With advantages such as low power consumption, tunable synaptic plasticity, and mechanical flexibility, they are emerging as next‐generation core technologies for real‐time ...

Role of dynamical particle-vibration coupling in reconciliation of the $d_{3/2}$ puzzle for spherical proton emitters [PDF]

, 2001
It has been observed that decay rate for proton emission from $d_{3/2}$ single particle state is systematically quenched compared with the prediction of a one dimensional potential model although the same model successfully accounts for measured decay ...

Modular Electronic Microrobots With Onboard Sensor‐Program‐Steered Locomotion

Advanced Intelligent Systems, EarlyView.
Modular electronic smartlet microrobots integrate ambient‐light energy harvesting, photodetection, programmable CMOS control, and bubble‐based actuation within a sub‐millimeter fold‐up architecture. A 58‐bit on‐board CMOS chiplet enables sensor–program steered switching between independently addressable actuators, achieving closed‐loop 2D navigation in

Morphologically Uniform Electron Transport Layer Incorporating Conjugated Polymer for Efficient Charge Extraction in Tin Perovskite Solar Cells

Carbon Energy, EarlyView.
A compact and morphologically uniform electron transport layer is created by blending PC61BM with a small amount of P3HT. The optimized architecture enables efficient charge extraction and suppresses interfacial recombination, which enhances power conversion efficiency and strengthens long‐term operational stability in tin‐based perovskite solar cells,
