Designing efficient organic solar cells is limited by the energy required to overcome the mutual Coulomb attraction between electron and hole. Here, the authors reveal long-lived and disorder-free charge-transfer states enable efficient endothermic c

Modern MEMs gyros/accelerometers allow the angular velocity of pendula to be precisely measured and the angular acceleration to be calculated. For a compound pendulum, [Formula: see text], where a is the distance of the center of mass from the pivot,

10.1119/10.0005889.1The toppling motion of a uniform rectangular block is investigated as a function of the friction between its pivot edge and the horizontal surface on which it rests. Initially, the edge of the block remains stationary, but it inev

With developments in modern instrumentation such as microelectromechanical gyro/accelerometers, high speed video analysis, and precision shaft encoders, there is an increased interest in the study of the large angle oscillations of pendulums as an ex

Covalent organic frameworks (COFs) are a highly versatile group of porous materials constructed from molecular building blocks, enabling deliberate tuning of their final bulk properties for a broad range of applications. Understanding their excited-s

Oscillatory motion with damping proportional to the velocity is part of all upper-class physics courses and some introductory courses; however, the emphasis is primarily on the free amplitude decay. Microelectromechanical (MEMs) accelerometers allow

The variation of the period of oscillation of a pendulum with the amplitude is known as “circular error” to clockmakers, and can easily be observed even without modern laboratory instruments. There have therefore been many approximate formulae fo

The acceleration, velocity, and displacement of a glider on an air track undergoing oscillatory motion subject to viscous and dry frictional damping are investigated using an accelerometer, which allowed a detailed investigation of the dynamics, expe
