Abstract Hydrogen (H 2 ) sensors are of great significance in hydrogen energy development and safety monitoring. However, achieving fast effective detection low concentrations is a key problem to be solved sensing. In this work, we combined the excellent gas sensing properties tin(IV) oxide (SnO zinc (ZnO) with outstanding electrical reduced graphene (rGO) prepared palladium (Pd)-doped rGO/ZnO-SnO nanocomposites by hydrothermal method. The crystal structure, structural morphology, elemental...
Acetone is a biomarker found in the expired air of patients suffering from diabetes. Therefore, early and accurate detection its concentration breath such extremely important. We prepared Tin(IV) oxide (SnO2) nanospheres via hydrothermal treatment then decorated them with bimetallic PtAu nanoparticles (NPs) employing approach situ reduction. The topology, elemental composition, as well crystal structure materials were studied field emission scanning electron microscopy, transmission X-ray...
In this work, SnO2 nanoflowers were prepared by a simple one-step hydrothermal process. The morphology and structure of characterized SEM, TEM, Raman spectroscopy, XRD, which demonstrated the good crystallinity tetrahedron as-synthesized materials. addition, sensing properties studied in detail. It was found that nanoflower-based gas sensor exhibits excellent response (9.2 to 120 ppm), fast recovery (2/15 s 6 linearity correlation between (S) vs. concentration (C) (lgS = 0.505 lgC - 0.147,...
Hydrothermal carbonization (HTC) is an efficient conversion process that treats solid digestates from anaerobic digestion plants and converts it into valuable products. In this study, of swine manure (DS_M) rice straw (DS_S) were HTC-treated at 190 °C with biomass-to-water ratios 1:4 1:9. The hydrochars characterized physically chemically to elucidate their potential as a resource. the acidic, dissolved organic carbon (DOC), nitrogen (DON), Brunauer-Emmett-Teller surface area (SBET)...
In modern societies, the air quality in vehicles has received extensive attention because a lot of time is spent within indoor compartment vehicles. order to further understand level under different conditions new vehicles, vehicle interior (VIAQ) with three brands was investigated static and driving conditions, respectively. Air sampling analysis are conducted requirement HJ/T 400-2007. Static tests demonstrate that increasing temperature sunshine higher concentration types volatile organic...
Air microfluidic circuits have been widely concerned in the separation of atmospheric particulate matter, especially for portable matter detection devices. Currently, no systematic approach design and optimization an air-microfluidic system PM has reported literature. In this paper, a two-stage air circuit is designed. The process divided into two stages: first, preliminary structure completed according to aerodynamic theory. Then, influences various factors (such as flow channel width, tilt...
氮素利用效率用于反映当季作物从肥料中同化的氮量, 这在农业生产实践中至关重要。不合理的氮肥施用将导致土壤板结、地下水污染以及作物品质下降等一系列问题, 因此近年来备受关注。本文以中国农业大学曲周试验站日光温室有机蔬菜生产长期定位试验为基础, 借鉴前人对于氮素平衡的研究方法, 即氮盈余=氮输入(肥料氮+移栽苗带入氮+灌水带入氮) 氮输出(收获物带出氮), 研究2011年春季有机、无公害和常规3种温室茄子种植模式下土壤氮素表观平衡的盈余变化。结果表明: 有机、无公害、常规3种种植模式下, 土壤耕层0~20 cm土壤全氮含量差异极显著, 其中有机生产模式最高, 为2.6 g·kg<sup>-1</sup>, 无公害生产模式为1.7 常规生产模式最低, 为1.3 g·kg<sup>-1</sup>; 3种种植模式下氮素的总输入分别为1 150 kg·hm<sup>-2</sup>、1 182 kg·hm 2、1 433 kg·hm<sup>-2</sup>, 总输出分别为178 kg·hm<sup>-2</sup>、135 kg·hm<sup>-2</sup>、116...
The act of standing up is one the most important movements in daily life, but it often poses challenges for elderly individuals with declining physical functions. To address this issue, we have designed an assistive device sit-to-stand (STS) movement. This aids upper limbs, allowing them to bear some weight during STS movement, thereby improving force distribution on lower limbs and enhancing stability body connection user very straightforward; simply needs place their hands arms lifting...
Abstract We prepared Pt-Ni high-index crystalline nanoparticles with various molar ratios to study the microscopic morphology and electrochemical properties of these catalysts. The results demonstrated that when Pt: Ni is 1:1, catalyst has most uniform optimal catalytic activity, as evidenced by an active area 8.546 m 2 /g, current density 1.544 mA/cm for ethanol oxide 1100 s steady state 1.132 . nanocatalysts have such high efficiencies due abundance step atoms doping non-precious metal nickel.
Compared with lever-type amplification mechanisms, bridge-type flexible mechanisms have advantages in terms of ratio and structural compactness. Therefore, they can effectively replace the mechanism existing hair-like sensors realize development miniature high sensitivity. With that mind, a highly sensitive sensor based on distributed flexibility is presented to measure airflow rate. First, composition operating principle are described. Then, detailed design analysis carried out, focusing...
