In this paper, a new wideband coplanar waveguide (CPW) rhomboid slot antenna by using conductor-backed coplanar waveguide (CBCPW) feeding, which works at 4.6 GHz with a relative impedance bandwidth of about 55.6 %, and a gain of more than 5.

Variations and influencing factors of vegetation net primary productivity over 31 years in Wuyishan National Park, China.

In this study, the Carnegie-Ames-Stanford approach model was used to estimate the net primary productivity (NPP) of Wuyishan National Park from 1990 to 2020. Variation in NPP in parks was examined, and the influencing factors were identified. NPP showed an increasing trend annually with climate change.

Ni-CoSe heterojunction coated by N-doped carbon for modified separators of high-performance Li-sulfur batteries.

Functional separators modified by transition metal compounds have been proven to be effective in suppressing the shuttle effect of polysulfides and accelerating sluggish electrode dynamics in lithium-sulfur batteries (LSBs). However, the behaviors of heterojunctions composed of transition metals and their compounds in LSBs are still rarely studied. Herein, we report a novel Ni-CoSe heterostructure coated with nitrogen-doped carbon.

Oxygen Vacancy-Mediated CuWO/CuBiO Samples with Efficient Charge Transfer for Enhanced Catalytic Activity toward Photodegradation of Pharmacologically Active Compounds.

Photocatalytic degradation is a promising method for controlling the increasing contamination of the water environment due to pharmacologically active compounds (PHACs). Herein, oxygen vacancy (OV)-modulated Z-scheme CuWO/CuBiO hybrid systems were fabricated thermal treatment by loading of CuWO nanoparticles with OVs on CuBiO surfaces. The synthesized CuWO/CuBiO hybrid samples exhibited an enhanced photodegradation ability to remove PHACs under visible-light irradiation.

Facile synthesis of Si/Ge/graphite@C composite with improved tap density and electrochemical performance.

Nanoengineering is one of the most effective methods to promote the lithium storage performance of silicon material, which suffers from huge volume changes and poor reaction kinetics during cycling. However, the commercial application of nanostructured silicon is hindered by its high manufacturing cost and low tap density. Herein, a Si/Ge/graphite@C composite was successfully synthesized by ball-milling with subsequent calcination.

Zinc-Air Battery-Based Self-Powered Sensor with High Output Power for Ultrasensitive MicroRNA let-7a Detection in Cancer Cells.

Self-powered sensors do not require a power supply and are easy to miniaturize, which have potential for constructing wearable, portable, and real-time detection devices. However, it is challenging for the detection of low abundant targets due to the low output power density of fuel cells and much interference of complex biological environment. Herein, a new kind of photocatalytic zinc-air battery-based self-powered electrochemical sensor (ZAB-SPES) was constructed for the detection of microRNA let-7a (miRNA let-7a) by combining magnetic nanobeads (MBs) with a metal-organic framework loaded with glucose oxidase (MOFs@GOX).

Highly-efficient and selective adsorption of anionic dyes onto hollow polymer microcapsules having a high surface-density of amino groups: Isotherms, kinetics, thermodynamics and mechanism.

Organic dye pollution in the water environment is a problem of global concern. Adsorption is demonstrated as a promising technology to remove organic dyes from wastewater, in which the development of highly-efficient adsorbents is still the challenging task. Herein, we reported the facile fabrication of polyamine-based cyclophosphazene hybrid (PCP-NH) hollow microcapsules with cross-linked structure, generated by one-step precipitation polymerization between hexachlorocyclotriphosphazene and branched polyethyleneimine, and subsequent acetone treatment.

A comparative study on the effects of MRI- and CT-guided interventional therapies on uterine fibroids.

Objective: To compare the effects of MRI- and CT-guided interventional therapies on uterine fibroids.

Methods: A total of 280 patients with uterine fibroids who were treated in our hospital from August 2008 to February 2014 were selected and divided into a treatment group and a control group by random draw (n=140). The control group and the treatment group were subjected to CT- and MRI-guided interventional therapies for uterine artery embolization.

Effects of β-like cell autotransplantation through hepatic arterial intervention on diabetic dogs.

Exogenous insulin and EGFP genes were transduced into bone marrow mesenchymal stem cells of beagle dogs using the retroviral vector pMSCV to prepare β-like cells. These cells were autotransplanted into the liver of diabetic dogs through hepatic arterial intervention, and physiological indices before and after transplantation were monitored. Autotransplantation of β-like cells significantly improved blood sugar, insulin levels, and body mass of diabetic dogs (P < 0.

IGF-1 and VEGF can be used as prognostic indicators for patients with uterine fibroids treated with uterine artery embolization.

The aim of the present study was to investigate the association between serum vascular endothelial growth factor (VEGF) and insulin-like growth factor 1 (IGF-1) levels and the prognosis of patients with uterine fibroids following uterine artery embolization (UAE) treatment. A total of 70 patients with uterine fibroids and 20 healthy controls were enrolled in this study between 2012 and 2014. The serum levels of IGF-1 and VEGF were measured using ELISA.

Levels of serum superoxide dismutase and high sensitive C-reactive protein in type 2 diabetic patients with lower extremity vascular disease are enhanced by interventional treatment.

Objectives: This study is to determine the levels of serum superoxide dismutase (SOD) and high sensitive C-reactive protein (hs-CRP) in type 2 diabetic patients with lower extremity vascular disease before and after interventional treatment.

Methods: A total of 65 patients were enrolled in this study, including 35 mails and 30 females. Another 65 healthy individuals were used as control, including 41 males and 24 females.
