Abnormal wear analysis of straddle-type monorail vehicle running wheel tire

open access: yesAdvances in Mechanical Engineering, 2019
On the Chongqing’s straddle-type monorail train in China, serious abnormal wear of running wheel tires occurs in its routine use, leading to a series of safety, environmental, and economic concerns. To analyze the causes of abnormal wear, a dynamic model

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

open access: yesAdvanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Development and Validation of a Wear Model to Predict Polyethylene Wear in a Total Knee Arthroplasty: A Finite Element Analysis

open access: yesLubricants, 2014
Ultra-high molecular weight polyethylene (UHMWPE) wear in total knee arthroplasty (TKA) components is one of the main reasons of the failure of implants and the consequent necessity of a revision procedure.

A novel measuring technique to evaluate frictional characteristics of roll-slip contacts in polymer-metal pairs [PDF]

open access: yes, 2011
Tribology research is aimed for desirable frictional characteristic; especially in rolling/sliding of polymer-metal contacts which helps smooth operations and energy savings. Conventional roll-slip tests for few million cycles have significant deposit of

Prediction of metal pm emission in rail tracks for condition monitoring application [PDF]

open access: yes, 2011
Exposure to particulate material (PM) is a major health concern in megacities across the world which use trains as a primary public transport. PM emissions caused by railway traffic have hardly been investigated in the past, due to their obviously minor ...

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

open access: yesAdvanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Developing an optimised method for accurate wear testing of dental materials using the ‘Rub&Roll’ device

open access: yesScientific Reports
Dental materials are challenged by wear processes in the oral environment and should be evaluated in laboratory tests prior to clinical use. Many laboratory wear-testing devices are high-cost investments and not available for cross-centre comparisons ...
