Highly Crystalline and Semiconducting Imine‐Based Two‐Dimensional Polymers Enabled by Interfacial Synthesis

Verified

Hafeesudeen Sahabudeen, Haoyuan Qi, Marco Ballabio, Miroslav Položij et al.

Journal: Angewandte Chemie International EditionYear: 2020Citations: 165

Abstract Single‐layer and multi‐layer 2D polyimine films have been achieved through interfacial synthesis methods. However, it remains a great challenge to achieve the maximum degree of crystallinity in the 2D polyimines, which largely limits the long‐range transport properties. Here we employ a sur...

Aging effects on airflow distribution and micron-particle transport and deposition in a human lung using CFD-DPM approach

Verified

Md. Mizanur Rahman, Ming Zhao, Mohammad S. Islam, Kejun Dong et al.

Journal: Advanced Powder TechnologyYear: 2021Citations: 63

Understanding the transportation and deposition (TD) of inhaled aerosol particles in human lung airways is important for health risk assessment and therapeutic efficiency of targeted drug delivery. The particle TD into a human lung depends on lung anatomy, breathing pattern, as well as particle prop...

Nanoparticle transport and deposition in a heterogeneous human lung airway tree: An efficient one path model for CFD simulations

Verified

Md M Rahman, Ming Zhao, Mohammad S. Islam, Kejun Dong et al.

Journal: European Journal of Pharmaceutical SciencesYear: 2022Citations: 40

Understanding nano-particle inhalation in human lung airways helps targeted drug delivery for treating lung diseases. A wide range of numerical models have been developed to analyse nano-particle transport and deposition (TD) in different parts of airways. However, a precise understanding of nano-pa...

Numerical study of nanoscale and microscale particle transport in realistic lung models with and without stenosis

Verified

Md. Mizanur Rahman, Ming Zhao, Mohammad S. Islam, Kejun Dong et al.

Journal: International Journal of Multiphase FlowYear: 2021Citations: 33

The transport and deposition (TD) of inhaled aerosol particles in airways of human lungs are important for therapeutically targeted drug delivery in respiratory tracts. The airflow and particle TD depend on various aspects, including breathing pattern, geometry of lungs, particle properties and depo...

Effects of co-exposure to lead and manganese on learning and memory deficits

Verified

Ruili Guan, Tao Wang, Xiaoru Dong, Kejun Du et al.

Journal: Journal of Environmental SciencesYear: 2022Citations: 31

Lead (Pb) and manganese (Mn) are common neurotoxins. However, individuals are subject to co-exposures in real life, and it is therefore important to study these metals in combination. Weaning Sprague-Dawley rats were given ad libitum access to drinking water solutions containing Pb (100 mg/L), Mn (2...

Aerosol Particle Transport and Deposition in Upper and Lower Airways of Infant, Child and Adult Human Lungs

Verified

Md. Mizanur Rahman, Ming Zhao, Mohammad S. Islam, Kejun Dong et al.

Journal: AtmosphereYear: 2021Citations: 28

Understanding transportation and deposition (TD) of aerosol particles in the human respiratory system can help clinical treatment of lung diseases using medicines. The lung airway diameters and the breathing capacity of human lungs normally increase with age until the age of 30. Many studies have an...

A numerical study on sedimentation effect of dust, smoke and traffic particle deposition in a realistic human lung

Verified

Md. Mizanur Rahman, Ming Zhao, Mohammad S. Islam, Kejun Dong et al.

Journal: International Journal of Multiphase FlowYear: 2023Citations: 16

Inhalation of pollutants can be deadly for respiratory health, as toxic pollutants can penetrate the deep lungs which could occur severe respiratory infection and lead to life-threatening respiratory diseases. The excessive presence of pollutants in the environment increases the concern of potential...
