Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Improve Simulation of Plain Bearings in Dry and Mixed Lubrication Regime by Defining Locally Resolved Dry Friction Coefficients [PDF]

Tribology in Industry, 2015
Asperity friction is a main indicator for wear and heat conduction [1]. It occurs when thickness of oil film shrinks due to high load or slow speed. Friction is scientifically well known as long as it is dominated by laminar oil film effects.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Research on Fuel Offset Control of High-Pressure Common-Rail Diesel Engine Based on Crankshaft Segment Signals

Sensors, 2022
This paper studies the fuel supply offset of diesel engines based on the crankshaft segment signal. Engine nonuniformity refers to the crankshaft torque fluctuation caused by cylinder-to-cylinder differences caused by misfiring or differences in the fuel

On the applicability of empirical heat transfer models for hydrogen combustion engines [PDF]

, 2011
Hydrogen-fuelled internal combustion engines are being investigated as an alternative for current drive trains because they have a high efficiency, near-zero noxious and zero tailpipe greenhouse gas emissions.

Analysis of the influence of geometric accuracy on the preload and stress of engine connecting rod bolts

Scientific Reports
The pitch deviation, non-parallel end face, and middle diameter deviation generated during the machining process of connecting rod bolts will lead to changes in bolt preload and stress distribution under ideal conditions, and their effects under ...
