D‐stroi – a uniaxial load frame for X‐ray diffraction and imaging

Journal of Synchrotron Radiation, EarlyView.
A remote miniature load frame for X‐ray diffraction and imaging applications is presented. The load frame has been assessed for mechanical stability and suitability for various synchrotron X‐ray‐based techniques.We present a remotely controlled miniature load frame for in situ tensile deformation of millimetre‐sized metal samples in synchrotron X‐ray ...

Microstructure‐Resolved Modeling to Predicting and Regulating Lithium Plating‐Stripping Dynamics on Graphite Electrodes

Advanced Science, Volume 13, Issue 30, 28 May 2026.
ABSTRACT The lithium plating reaction in graphite electrodes acts as a root cause for the accelerated degradation and the internal short circuits in lithium‐ion batteries. Here, an electrochemical model based on multi‐scale microstructural images was established to identify lithium plating‐stripping processes, thereby supporting the predictive outcomes

Fuel Consumption and Emissions Reductions of Hybrid Electric Regional‐Haul Trucks Equipped with a High‐Pressure Direct Injection Natural Gas Engine in Real‐World Driving Conditions

Energy Technology, Volume 14, Issue 4, April 2026.
Integrating powertrain electrification with efficient engines using low‐carbon fuels like natural gas (NG) improves energy conversion efficiency and mitigates greenhouse gas (GHG) emissions in heavy‐duty (HD) trucks. High‐pressure direct injection (HPDI) NG engines, using less than 5% diesel (energy basis) as pilot fuel, offer diesel‐like efficiency ...

Planetary gearbox fault diagnosis using an on-rotor MEMS accelerometer [PDF]

2017 23rd International Conference on Automation and Computing (ICAC), 2017
Conventional accelerometers installed on housing often give out less accurate diagnostic results for planetary gearbox because the mesh excitation of planet gears change with carrier movement. Recent significant advancements in low-power and low-cost Micro-Electro-Mechanical Systems (MEMS) technologies make it possible and easier to mount MEMS ...

Enabling High‐Fidelity Wave‐Particle Interaction Studies: A Novel Filtering for Isolating Whistlers From Spacecraft Noise

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Resolving the mixture of natural plasma waves and persistent spacecraft interference is a fundamental challenge in space physics, as it obstructs the analysis of wave‐particle interactions and energy transport processes. Traditional signal decomposition methods often fail to adequately separate these components due to their time‐varying ...

Parametric oscillations in planetary wheel gearboxes

Bulletin of the National Technical University «KhPI» Series: Engineering and CAD, 2018
Разработана математическая модель параметрических колебаний в планетарных колесных редукторах (ПКР) троллейбусов. Модель учитывает циклические деформации тонкостенного обода и зубьев в зацеплении эпицикла с сателлитами. Дифференциальное уравнение колебаний эпицикла приведено к виду уравнений Матье-Хилла с переменными периодическими коэффициентами.
