The performance of proton exchange membrane fuel cells is heavily dependent on the microstructure electrode catalyst especially at low loadings. This work shows a hybrid electrocatalyst consisting PtNi-W alloy nanocrystals loaded carbon surface with atomically dispersed W sites by two-step straightforward method. Single-atomic can be found surface, which form protonic acid and establish an extended transport network surface. When implemented in assembly as cathode ultra-low loading 0.05 mgPt...
Abstract For Pd‐based alloy catalysts, the selection of metallic alloying elements and construction composition‐gradient surface subsurface layers are critical in achieving superior electrocatalytic activities in, e.g., oxygen reduction reaction (ORR). Based on Pd‐containing alloy, highly monodispersed PdCuNi ternary nanocrystals prepared through a wet‐chemical approach, solution‐based oxidative treatment protocol is utilized to activate nanocrystals. A drastically enhanced ORR activity can...
Abstract Background Archaeological studies have revealed a series of cultural changes around the Last Glacial Maximum in East Asia; whether these left any signatures gene pool Asians remains poorly indicated. To achieve deeper insights into demographic history modern humans Asia Maximum, we extensively analyzed mitochondrial DNA haplogroup M9a'b, specific that was suggested to some potential for tracing migration Eurasia. Results A total 837 M9a'b DNAs (583 from literature, while remaining...
A visual control system is designed for a table tennis robot with five degrees of Freedom (DOFs). It consists four parts such as ball sensing, trajectory predicting, motion planning, and control. highvelocity stereo vision parallel architecture developed to sense the motions ball. The striking parameters including position, velocity, time are predicted according based on several measured positions. computer receives performs planning robot. card embedded in results controls via servo drivers...
Abstract BACKGROUND Patients with basilar invagination and atlas occipitalization usually present abnormal anatomy of the vertebral arteries (VAs) at craniovertebral junction (CVJ). OBJECTIVE To describe further classify different types VA variations CVJ 3D visualization technology. METHODS One hundred twenty patients who had undergone 3-dimensional computed tomographic angiography (3D-CTA) were retrospectively studied. Imaging data processed via separating, fusing, opacifying,...
A ping pong robot with 5 degree of freedoms is designed in this paper. It consists a PC, high speed stereovision system two smart cameras, AC servo motors and step motors. The hitting task the divided into three stages: measurement prediction stage, planning stage execution stage. In we propose series methods to plan paddle trajectory, posture, according information. Experiments versus person are well conducted. experimental results verify effectiveness proposed methods.
Over the years, hydrostatic balance slipper is often used to make hydraulic lubrication film formed between swash plate and slipper. In this paper, a containing powder metallurgy (PM) composite material proposed. The porous characteristics have an automatic damping effect, which can improve tribological of Based on Reynolds equation, Darcy law continuity model PM damper proposed analyze effect in paper. calculated using finite volume method capture water characteristics. Effects length,...
