Tuning the ambipolar behavior in charge carrier transport via defect-engineering is crucial for achieving high mobility transistors for nonlinear logic circuits. Here, we present the electric-field tunable electron and hole transport in a microchannel device consisting of highly air-stable van der Waals (vdW) noble metal dichalcogenide (NMDC), PdSe$_\mathrm{2}$, as an active layer. Pristine bulk PdSe$_\mathrm{2}$ constitutes Se surface vacancy defects created during the growth or exfoliation process and offers an ambipolar transfer characteristics with a slight electron dominance recorded in f...

Controlling charge transport through molecules is challenging because it requires engineering of the energy of molecular orbitals involved in the transport process. While side groups are central to maintaining solubility in many molecular materials, their role in modulating charge transport through single-molecule junctions has received less attention. Here, using two break-junction techniques and computational modeling, we investigate systematically the effect of electron-donating and -withdrawing side groups on the charge transport through single molecules. By characterizing the conductance ...

Mechanical vibrations are being harnessed for a variety of purposes and at many length scales, from the macroscopic world down to the nanoscale. The considerable design freedom in mechanical structures allows to engineer new functionalities. In recent years, this has been exploited to generate setups that offer topologically protected transport of vibrational waves, both in the solid state and in fluids. Borrowing concepts from electronic physics and being cross-fertilized by concurrent studies for cold atoms and electromagnetic waves, this field of topological transport in engineered mechanic...

Training of new transportation engineers at the technical universities, constitution of transportation engineering organisations in large and medium-sized cities and an effective state support for the organisation and management measures adopted by these agencies helped to relieve the situation. A survey is given of tasks devolving upon transportation engineering organisations. The transportation poli...

This chapter describes how the bicycle is a flexible mode of transportation that can be used for a variety of trips within the intermodal transportation system and by a wide range of people. Creative designs have been required in many cases to retrofit our auto-dominated road system to promote and encourage bicycling. However, over the last decade strong progress has been made throughout the United States in order to reintroduce well-engineered bicycle transportation facilities into cities, towns, and rural areas. A wide range of guidance is available for designers who may not be cyclists or b...

This chapter describes how previous research conducted by Pouliot (2002) indicates that transportation represents one of the most important human activities worldwide. Furthermore, he maintains that transportation is a multidimensional service that affects many aspects of daily life. While transportation is complex and multifaceted, it could be viewed as simply the movement between two or more points. According to Wood and Johnson (1996), transportation is the physical movement of people and goods between points. Therefore, transportation is a very broad, generic term and it consists of three ...

Internal Combustion Engines (ICE) are experiencing a transition era in which research and innovation are mainly pushed by environmental issues: emission reduction and fuel saving are indispensable requirements of the new technologies, otherwise the end of ICE is proposed in Europe. Modifications, in reality, are under discussion by 2026 but the environmental issues are anyway welcomed. In the transportation sector, today dominated by ICEs, it appears that the reduction in the propulsion power, hybridization at various degrees, and exhaust post-treatment improvements will guarantee technologica...

This chapter describes how diesel-electric locomotives and electric locomotives are classified by wheel arrangement with letters representing the number of axles in a rigid truck (A for one axle, B for two axles, C for three axles, etc.). Idler axles between drivers may be numerals. A plus sign indicates articulated trucks or motive power units. A minus sign indicates separate nonarticulated trucks. This nomenclature is explained in RP-5523, issued by the Association of American Railroads (AAR). Virtually all modern locomotives are of either B-B or C-C configuration. The high efficiency of the...

The method of mathematically modelling a physical phenomenon involving fluid flow and solving it numerically using analytical prowess is known as computational fluid dynamics (CFD). Aerodynamics plays an important part in the manufacturing phase when an architect is tasked with developing a new vehicle, such as a winning racing car for the coming season. Aerodynamic processes, on the other hand, are difficult to quantify during the concept stage. Physical checks on product samples are typically the only way for an inventor to refine his designs.

The premise of this review is that the nature of the time-dependent phase transitions in dynamic electrochemical environments serves as an important design parameter, orthogonal to the intrinsic mixed conducting properties of the active materials in battery electrodes, and that successful suppression of the tendency of extrinsic resistances to accumulate over time is a requirement for practical rechargeable batteries and an important target for rational design.

Anomalous transport of topological semimetals has generated significant interest for applications in optoelectronics, nanoscale devices, and interconnects. Understanding the origin of novel transport is crucial to engineering the desired material properties, yet their orders of magnitude higher transport than single‐particle mobilities remain unexplained. This work demonstrates the dramatic mobility enhancements result from phonons primarily returning momentum to electrons due to phonon‐electron dominating over phonon–phonon scattering. Proving this idea, proposed by Peierls in 1932, requires ...

Charge‐transport layers are essential for achieving electrically pumped perovskite lasers. However, their role in perovskite lasing is not fully understood. Here, the role of charge‐transport layers on the lasing actions of perovskite films is explored by investigating the amplified spontaneous emission (ASE) thresholds. A largely reduced ASE threshold and enhanced ASE intensity is demonstrated by introducing an additional hole transport layer poly(triaryl amine) (PTAA). It is shown that the key role of the PTAA layer is to accelerate the hot‐carrier cooling process by extracting holes in pero...
