Biglycan and chondroitin sulfate play pivotal roles in bone toughness via retaining bound water in bone mineral matrix
(Matrix Biology;Vol. 94, 9/28/2020)
Recent in vitro evidence shows that glycosaminoglycans (GAGs) and proteoglycans (PGs) in bone matrix may functionally be involved in the tissue-level toughness of bone. In this study, we showed the effect of biglycan (Bgn), ...
Influence of Cs Loading on Pt/m-ZrO2 Water–Gas Shift Catalysts
(Catalysts;11(5), 4/29/2021)
Certain alkali metals (Na, K) at targeted loadings have been shown in recent decades to significantly promote the LT-WGS reaction. This occurs at alkali doping levels where a redshift in the C-H band of formate occurs, ...
Hydrocracking of Octacosane and Cobalt Fischer–Tropsch Wax over Nonsulfided NiMo and Pt-Based Catalysts
(9/30/2021)
The effect of activation environment (N<sub>2</sub>, H<sub>2</sub> and H<sub>2</sub>S/H<sub>2</sub>) on the hydrocracking performance of a NiMo/Al catalyst was studied at 380 °C and 3.5 MPa using octacosane (C<sub>28</sub>). ...
Portable Medical Suction and Aspirator Devices: Are the Design and Performance Standards Relevant?
(3/25/2022)
Airway clearance refers to the clearing of any airway blockage caused due to foreign objects such as mud, gravel, and biomaterials such as blood, vomit, or teeth fragments using the technology of choice, portable suction ...
Knockdown Indian Hedgehog (Ihh) does not delay Fibular Fracture Healing in genetic deleted Ihh mice and pharmaceutical inhibited Ihh Mice
(Scientific Reports;8, 7/9/2018)
The objective of this study was to determine if Ihh is required for fracture healing. Fibular fracture was created in adult Col2a1-CreERT2; Ihhfl/fl mice. Ihhfl/fl mice received Tamoxifen (TM) to delete Ihh. WT mice received ...
An improved interfacial bonding model for material interface modeling
(Engineering Fracture Mechanics;169, 2017-01)
An improved interfacial bonding model was proposed from potential function point of
view to investigate interfacial interactions in polycrystalline materials. It characterizes both
attractive and repulsive interfacial ...
Effect of water on nanomechanics of bone is different between tension and compression
(Journal of the Mechanical Behavior of Biomedical Materials;57, 2016-04)
Water, an important constituent in bone, resides in different compartments in bone matrix and may impose significant effects on its bulk mechanical properties. However, a clear understanding of the mechanistic role of water ...
Bioinspired design of hybrid composite materials
(International Journal of Smart and Nano Materials;10(1), 11/24/2018)
Mimicking the natural design motifs of structural biological materials is a promising approach to achieve a unique combination of strength and toughness for engineering materials. In this study, we proposed a 2D computational ...
Design, Modeling, and Control of a Differential Drive Rimless Wheel That Can Move Straight and Turn
(7/19/2021)
A rimless wheel or a wheel without a rim, is the simplest example of a legged robot and is an ideal testbed to understand the mechanics of locomotion. This paper presents the design, modeling, and control of a differential ...
Physics of unsteady cylinder-induced shock-wave/transitional boundary-layer interactions
(Journal of Fluid Mechanics;Volume 918, 2021-05-14)
Given the current lack of experimental data for shock waves interacting with incoming transitional boundary layers, the goal of this study was to characterize the dynamics of such an interaction to better understand the ...
