Due to substantial development of electronics and telecommunication techniques, materials with electromagnetic interference (EMI) shielding performance are significant in alleviating the impacts induced from a remarkable variety devices. In work, we propose novel sandwich structures for manipulating EM wave transport, which holds unique EMI features frequency selectivity. By employing electrical magnetic loss spacers, resultant endowed tunable performance, showing improvements overall...
Ultra-broad-band electromagnetic absorption materials and structures are increasingly attractive for their critical role in competing with the advanced broad-band detection systems. Mechanically soft weak wax-based composites known to be insufficient serve practical applications. To break through such barriers, here we developed an innovative strategy enable robust repairable meta-structures by employing a three-dimensional (3D) printed polymeric patterned shell. Because of integrated merits...
Smart materials and structures with tunable electromagnetic (EM) properties are highly demanded for active environmental sensitive systems. As polar molecules in the environment, this work, water ice utilized as wetting freezing conditions to manipulate response behaviors a graphene-based composite material, aiming achieve smart weather-manipulated EM metamaterial. Owing introduced phase self-assembled porous attenuating networks, energy consumption of waves is significantly altered via...
Dynamic hip screws (DHS) and proximal femoral nail anti-rotation (PFNA) were recommended for basicervical neck fracture (BFNF), however, with high rate of postoperative shortening. The bionic (PFBN) was designed to decrease the complications associated DHS PFNA. aim this study is compare biomechanical characters DHS, PFNA, PFBN fixation BFNF. Using finite element analysis, we created a three-dimensional model BFNF investigation. group, PFNA group + DS our three test groups. For each von...
A resistive metasurface featured by the Rossler chaos reaction-diffusion system patterns is proposed and realized in a wideband electromagnetic absorber. The surface consists of units with both random shapes dimensions. Simulation results show absorption phenomenon, correlation function analysis indicates new wave-absorbing mode can be generated when edges matches geometrical size units. Experimental indicate unconventional bandwidth ratio reflectivity lower than –10, –15, –19 dB reaches...

Objective To observe the effects of boundary conditions and connect on biomechanics predictions in finite element ( FE ) pelvic models. Methods Three models were constructed to analyze effect hip joint: an intact model assumed contact joint both sides (Model I); a connecting surfaces fused together with II or without proximal femurs III ). The was validated by bone surface strains obtained from strain gauges vitro experiment. Vertical load applied specimen, same simulated model. Results...
Cannulated screws (CS) are one of the most widely used treatments for femoral neck fracture, however, associated with high rate complications. In this study, we designed a new type cannulated called degradable magnesium alloy bionic (DMBCS) and our aim was to compare biomechanical properties DMBCS, traditionally titanium (TBCS) (TTCS).A proximal femur model established based on CT data lower extremity from voluntary healthy man. Garden III fracture constructed fixed TBCS, TTCS, respectively....
To compare the stability of sacroiliac joint disruption fixed with three kinds internal fixation using both biomechanical test and finite element analysis. Five embalmed specimens an adult were used. The symphysis pubis rupture left created. was stabilized a five-hole plate. in randomized design. Displacements whole specimen shifts gap recorded. Three-dimensional models pelvis, pelvis disruption, techniques created analyzed. Under vertical load, displacements minimally invasive adjustable...
Objective To compare the biomechanical stability and compatibility of two iliosacral screws (ISS), a tension band plate (TBP), minimally invasive adjustable (MIAP) for treating Tile C pelvic fractures. Methods Three groups finite element models intact pelvis, including main ligament proximal one‐third both femurs, were developed to simulate vertical sacral fractures treated with three abovementioned internal fixation techniques. A 500 N load, load plus 10 Nm moment forward sagittal...
Abstract Background Limited information exists on the incidence of postoperative deep venous thromboembolism (DVT) in patients with isolated patella fractures. The objective this study was to investigate and locations thrombosis lower extremity who underwent fractures identify associated risk factors.

Methods Computed tomography images an adult male volunteer appropriate age in good physical condition were used establish three‐dimensional model proximal femur. Then, type 31A1 fracture femur was established, nails fixation, respectively. The von Mises stress, maximum principal minimum stress calculated...
Purpose: Internal fixation device failure is rare but unavoidable. Fatigue-related mechanisms are responsible for most mechanical failures of orthopedic plates. Plate design needs to be optimized both long fatigue life and bone healing. Only in this way can we reduce the occurrence internal failure. To address issue, aimed provide a theoretical basis improving Material Methods: The finite element method was used conduct computational investigation. Three groups plate models were designed...
Femoral shaft fracture is one of the most common types encountered in clinic. For certain complex femoral fractures, traditional intramedullary nail may not provide sufficient stability. Therefore, novel systems are required. The femur 3D model and internal fixation were designed using Mimics 17.0 (Materialise), Geomagic Studio 2012 (Raindrop) Solidwork 2016 (Dassault) software. validity models was verified through comparison with previous data silico. To further simulate comminuted...
