Microwave synthesis of LTN framework zeolite with no organic structure directing agents
We present a new microwave synthesis method of Linde Type N zeolite without organic structure directing agents (OSDAs). Linde Type N zeolite (framework type LTN) is one of the most complex zeolite structures with a very large...
Effect of mono- and divalent extra-framework cations on the structure and accessibility of porosity in chabazite zeolites
Chabazite (CHA), one of the most common zeolite framework types, has a remarkable capacity to accommodate a wide range of different cations within the unique CHA framework. This has led to CHA being applied extensively in ion...

Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are members of the voltage-gated cation channel family known to be expressed in the heart and central nervous system. Ivabradine, a small molecule HCN...
Discrete mineralisation of the acetabular labrum
Femoroacetabular impingement (FAI) is increasingly thought to play a role in the development of hip osteoarthritis, but is difficult to define clinically and on imaging. This study investigates mineralisations of the acetabular...

Oct 03, 2018
Glacial-state greenhouse gas concentrations and Southern Hemisphere climate conditions persisted until ∼17.7 ka, when a nearly synchronous acceleration in deglaciation was recorded in paleoclimate proxies in large parts of the...
Study of an overmoded structure for megawatt Ka-band extended interaction klystron
Yifan Zu, Xuesong Yuan, Xiaotao Xu, Qingyun Chen, Matthew T. Cole, Yong Yin, Hailong Li, Bin Wang, Lin Meng, Yang Yan
Oct 31, 2023
For most applications in the millimeter wave band, corresponding to Ka and higher-frequency bands, relatively high atmospheric absorption necessitates the use of high-power sources. Here, a new approach for projecting an...

A Carbon Nanotube-based Hundred Watt-level Ka-band Backward Wave Oscillator
Carbon nanotube (CNT) cold-cathodes hold much promise in a variety of millimeter-wave and terahertz vacuum electronic radiation devices due to their inherent near instantaneous temporal turn-on and near-ideal ideal field...

Femoroacetabular impingement
Femoroacetabular impingement (FAI) is a clinical syndrome in which the anatomical abnormalities of the femoral ead and/or the acetabulum result in abnormal contact between the femur and acetabulum during normal hip motion...
Over one third of patients with symptomatic femoroacetabular impingement display femoral or acetabular version abnormalities.

Aug 26, 2021
PURPOSE: The aim of this study was investigate the relationship between version and torsional abnormalities of the acetabulum, femur and tibia in patients with symptomatic FAI. METHODS: A systematic review was performed...
The history of femoroacetabular impingement.
AIMS: Femoroacetabular impingement (FAI) describes abnormal bony contact of the proximal femur against the acetabulum. The term was first coined in 1999; however what is often overlooked is that descriptions of the morphology...
