We will highlight the main achievements made recently in preparation and application of 3D graphene porous materials lithium-ion batteries, super-capacitors, solar cells, catalysis, thermal management, environment pollution enrichment separation, chemical sensors, <italic>etc</italic>.
Background Asthma is a complex pulmonary inflammatory disease, which characterized by airway hyperresponsiveness, variable airflow obstruction and inflammation in the airways. The majority of asthma allergic asthma, disease caused type I hypersensitivity mediated IgE. Exposures to number environmental chemicals are suspected lead one such pollutant di-(2-ethylheyl) phthalate (DEHP). DEHP manufactured chemical that commonly added plastic products make them flexible. Epidemiological studies...
There has been increasing interest in the concept that exposure to environmental chemicals may be contributing factors epidemics of diabetes mellitus (DM). Triclocarban and triclosan (TCs) are synthetic antibacterial widely used personal care products. Studies have shown TCs endocrine disruptors alter metabolic conditions. However, it remains unclear whether is a risk factor for impaired glucose tolerance (IGT) type 2 (T2DM). We explored hypothesis associated with an increased IGT T2DM. To...
Background The great advances of nanomaterials have brought out broad important applications, but their possible nanotoxicity and risks not been fully understood. It is confirmed that exposure environmental particulate matter (PM), especially ultrafine PM, are responsible for many lung function impairment exacerbation pre-existing diseases. However, the adverse effect nanoparticles on allergic asthma seldom investigated mechanism remains undefined. For first time, this work investigates...
In this letter, two simple and novel circular slot antenna systems to generate OAM waves are proposed. Special feeding networks, which can be used modes, designed at 2.4 GHz feed the antenna. Furthermore, fabricated tested. Both simulation measurement results demonstrate effectiveness of for generating waves.
A bstract We study the quantum coherence in de Sitter space for bipartite system of Alice and Bob who initially share an entangled state between two modes a free massive scalar field. It is shown that space-curvature effect can produce both local correlated coherence, leading to increase total system. These results are sharp different from Unruh or Hawking effect, which, single mode approximation, cannot at same time destroy decrease systems. Interestingly, we find has opposite behavior...
Abstract Leaf photosynthetic nitrogen‐use efficiency (PNUE) diversified significantly among C 3 species. To date, the morpho‐physiological mechanisms and interrelationships shaping PNUE on an evolutionary time scale remain unclear. In this study, we assembled a comprehensive matrix of leaf morpho‐anatomical physiological traits for 679 species, ranging from bryophytes to angiosperms, comprehend complexity underpinning variations. We discovered that mass per area (LMA), mesophyll cell wall...
Remote sensing of HDO and CH4 could provide valuable information on environmental climatological studies. In a recent contribution, we reported 3.53 μm distributed feedback (DFB) inter-band cascade laser (ICL)-based heterodyne radiometer. the present work, details measurements inversions at Dunhuang, Northwest China. The instrument line shape (ILS) radiometer (LHR) is discussed firstly, spectral resolution about 0.004 cm−1 theoretically according to ILS. Furthermore, retrieval algorithm,...
Toroidal dipole resonance can significantly reduce radiation loss of materials, potentially improving sensor sensitivity. Generally, toroidal response is suppressed by electric and magnetic dipoles in natural making it difficult to observe experimentally. However, as 2D metamaterials, metasurfaces weaken the dipole, enhancing response. Here, we propose a new graphene-integrated metasurface an ultra-sensitive chemical sensor, capable qualitative detection chlorothalonil terahertz region, down...
A passive optical fiber laser heterodyne radiometer prototype with a semiconductor near 1.316 μm as the local oscillator was built, parameters of have been optimized. Using prototype, water vapor concentration in atmospheric column measured spectral resolution 0.009 cm −1 late October and early November 2020, collection time approximately 3 min, signal-to-noise ratio better than 120. The profiles were inversed based on optimal estimation method. Compared measurement Fourier transform...
As one of the main driving forces for change in surface energy balance, land use and cover affects ecological climate through different levels biogeochemical physical processes. However, many studies on balance are conducted from perspective biogeochemistry, ignoring By using core methods such as algorithm Mann-Kendall trend test, we analyzed mechanism effects five types Huang-Huai-Hai Basin China. The results showed that: (1) net radiation latent heat flux increased significantly, their...
Free-ranging Red-eared Sliders (Trachemys scripta elegans) were captured from farm ponds located in the Flint Hills of Kansas and a zoo pond Emporia, Kansas, USA, to evaluate their enteric bacterial flora associated antibiotic resistance. Bacteria obtained cloacal swabs composed six different Gram-negative genera. Although resistance was present turtles both locations, 40 49% bacteria demonstrated multiple four antibiotics tested turtles, respectively. These data illustrate environmental is...
In this paper we present experimental results on the laser power stabilization of detection system in Cs fountain clock. order to stabilize power, have constructed a feedback loop by using an acousto-optic modulator, photodetector, and servo controller.

Caesium atomic fountain clock is a primary frequency standard, which realizes the duration of second. Its performance mostly dominated by accuracy, and C-field induced second-order Zeeman shift major effect, limits accuracy improvement. By applying high-precision current supply high-performance magnetic shieldings, stability has been improved significantly. In order to achieve uniform C-field, this paper proposes doubly wound solenoid, compensates radial field along flight region generated...
