Insulator-metal transition is investigated self-consistently on the frustrated Shastry-Sutherland lattice in the framework of Slave-Boson mean-field theory. Due to the quasi-flat band structure characteristic, the system displays a spin-density-wave (SDW) insulating phase at the weak doping levels, which is robust against frustration, and it will be transited into a SDW metallic phase at high doping levels. As further increasing the doping, the temperature or the frustration on the diagonal linking bonds, the magnetic order $m$ will be monotonically suppressed, resulting in the appearance of a paramagnetic metallic phase. Although Fermi surface of SDW metallic phase may be immersed by temperature, the number of mobile charge is robust against temperature at small doping levels.

We report the observation of electric-voltage induced insulator-metal phase transition in a ruthenate Mott insulator Ca3(Ru0.9Ti0.1)2O7. We show that the electric field effect dominates and leads to a...
We explore the electrical characteristics of TiS nanowire field-effect transistor (FETs), over the wide temperature range from 3 - 350 K. These nanomaterials have a quasi-one-dimensional (1D) crystal ...
By means of first principles schemes based on magnetically constrained density functional theory and on the band unfolding technique we study the effect of doping on the conducting behaviour of the Li...
The metal-insulator phase transition in magnetite, known as the Verwey transition, is characterized by a charge-orbital ordering and a lattice transformation from a cubic to monoclinic structure. We u...
Two-dimensional materials have proven to be a prolific breeding ground of new and unstudied forms of magnetism and unusual metallic states, particularly when tuned between their insulating and metalli...
The primary objectives of this study are to evaluate the performance of StatSeal Advanced used in conjunction with the TR Band (SSA) as compared to the TR Band without SSA (TRB) relative t...
This is a multi-center, randomized study to compare blood and urine cobalt, chromium, and titanium ion levels of a metal-on-metal articular bearing coupled with two different head sizes to...
The aim of this study is to demonstrate the non-inferiority of the ceramic-on-metal articulation using large diameter bearings (38mm to 60mm) compared to the metal on metal articulation us...
A clinical Evaluation to determine metal ion release from 4th generation metal-on-metal hip articulating surfaces in cementless total hip arthroplasty.

The reaction of two molecular entities via oxidation usually catalyzed by a transition metal compound and involving dioxygen as the oxidant.
Phenotypic changes of EPITHELIAL CELLS to MESENCHYME type, which increase cell mobility critical in many developmental processes such as NEURAL TUBE development. NEOPLASM METASTASIS and DISEASE PROGRESSION may also induce this transition.
