Fabrication of a high quality quantum dot (QD) film is essentially important for high-performance QD light emitting diode display (QLED) device. It normally high-cost and multiple-step solution-transfer process where large amounts QDs were needed but with only limited usefulness. Thus, developing simple, efficient, low-cost approach to fabricate high-quality micropatterned urgently needed. Here, we proposed that the Chinese brush enables controllable transfer solution directly onto...

Stress shielding ​(SS) is considered the main mechanical cause of femoral stem loosening after total hip arthroplasty (THA). This study introduces an auxetic lattice structure with negative Poisson's ratio that can expand laterally, intent transferring more load to surrounding bone and thereby reducing SS. aims evaluate how geometry profile different stems structures affects level Different re-entrant angles for unit cells were also evaluated.This assessed three commercial designs (Mayo, CLS...

Introduction Medial Opening-wedge High Tibial Osteotomy (HTO) is an effective treatment for medial compartment osteoarthritis and knee varus in relatively young active patients. While it can effectively correct lower limb alignment the coronal plane, may also affect posterior tibial slope (PTS) sagittal plane. However, factors influencing PTS methods maintaining stability remain controversial. Methods A geometric model was constructed based on CT data from a patient with knee. Multiple...

Occlusal forces cause stress which morphologically affects the supporting tissues of implants. The aim this study was to examine effects occlusal on distribution neurofilament protein (NFP)-positive nerve fibers in tissue peri-implant bone. bilateral 2nd, 3rd and 4th mandibular premolars 1st molars were extracted from three mongrel dogs. After 4 months healing, screw-type implants inserted oral cavity. Three after insertion, molar site loaded by forces, while those premolar unloaded. a...

Both forelimbs of rats were amputated, and these kept in the custom-made cages that prolonged upright posture. Pathologic changes observed lumbar spine at different time points after surgery.To investigate effect posture on intervertebral discs rat spine.Previous studies have shown increased axial forces can decrease height disc, but there are no data to indicate whether or not long-term repeated assumption could result degenerative changes.The 30 amputated when they 1-month old. These...

Abstract Micro‐patterning silver nanowires (AgNWs) via solution processes is vital in making high‐performance transparent flexible electrodes (TFE) that have been widely used optoelectronic devices. However, it has suffered from the limitation of a trade‐off relationship between coverage and arrangement AgNWs, which determine transparency conductivity, respectively. Here, unique AgNWs micro‐patterns, featuring as crossing‐grid high‐resolution highly‐aligned micro‐lines, enable micro‐pattern...

Most chronic neck pain is the result of degeneration cervical spine. IL-1beta may play an important role in intervertebral disc degeneration. This being case, inhibiting could provide a therapeutic approach for reducing or preventing Muscone reportedly relieves and suppresses inflammation. Therefore, we asked whether muscone, potent antiinflammatory agent, reduce proinflammatory cytokines vitro (end-plate cartilage cultures) end-plate vivo (a rat model that induces degeneration). In vitro,...

Aseptic loosening of the glenoid component is one main reasons for high revision rates reverse total shoulder arthroplasty (RTSA). It has been reported that bulky implant designs may lead to stress shielding. However, it uncertain whether shielding effect severe enough bone resorption and loosening. The purpose this study was evaluate level stress-shielding assess plays a role in aseptic following RTSA. A cadaveric vitro test model used validate finite element (FEM) scapula. FEM scapula,...

Background: The prevalence of nonunion after the Latarjet procedure remains high. purpose present study was to investigate healing and clinical outcomes a novel arthroscopic coracoid process transfer procedure. Methods: Sixty-three patients who underwent inlay Bristow combined with Bankart repair were identified, 51 met inclusion criteria enrolled in this study. key feature technique that trimmed fixed into trough (5 10 mm deep) glenoid neck metal screw. Bone graft union positioning accuracy...

The mechanical and tribological properties of a new biomaterial, an ultra high molecular weight polyethylene-hyaluronan (UHMWPE-HA) microcomposite, were investigated in this article, which is Part II two-part study. I presented the synthesis physical/chemical characterization novel microcomposites. microcomposite was developed for bearing surfaces total joint replacements designed to enhance lubrication improve wear resistance compared noncrosslinked UHMWPE. Pin-on-flat tests with cross-path...

Summary An improved nanocomposite‐based packaging material (NCP) was prepared by blending polyethylene with nano‐Ag, nano‐TiO 2 and attapulgite. And its effect on preservation quality of green tea (Biluochun Qingfeng) during one‐year ambient storage investigated. The results showed that adding nanoparticles to the could significantly improve barrier property. After storage, moisture Biluochun Qingfeng NCP decreased 10.3% 6.1% compared normal material. Meanwhile, contents amino acid,...

In this paper, a novel joint hybrid time–frequency (TF) analysis method based on the Hadamard product of Choi–Williams transform and smoothed pseudo Wigner–Ville distribution has been proposed in interference detection for Global Navigation Satellite System (GNSS) receivers. The tested by experiments interfered GPS L1 signals comparison with state-of-the-art approaches. results show that effectively eliminates cross-terms present bilinear TF and, at same time, provides much improved...

Based on the coffee ring effect, we have reviewed recent progress in controllable patterning of nanoparticles using solution transfer approaches, as well mechanism involved and applications various fields.

For a magnetically suspended control moment gyro (MSCMG), the high-speed rotor is actively by magnetic bearings of 5-DOF, but nonlinearity suspension force one main reasons for poor accuracy radial translation (MSR). To solve this problem, here, characteristics are analyzed, and nonlinear dynamic model MSR established. A sliding mode (SMC) based on neural network presented, basis function (RBF) adopted to approximate displacement stiffness current weaken chattering in SMC improve MSR. The...
