Land-use affecting organic carbon and its active components in soil aggregates ...

Liu, Xiaoqian; Guo, Kaiwen; Li, Bin; Li, Xin; Li, Wei

Due to large-scale wetland reclamation, the typical wetland had been conversed to different wetland use types (upland field, paddy field, and artificial forest) in the Sanjiang Plain. However, there are scarce data regarding soil aggregates and active organic carbons during land-use transition. Here, soil aggregates and the changes in content and storage of active organic carbon [total organic carbon (TOC), dis...

Every year, for ten years now, the IPIN competition has aimed at evaluating real-world indoor localisation systems by testing them in a realistic environment, with realistic movement, using the EvAAL framework. The competition provided a unique overview of the state-of-the-art of systems, technologies, and methods for indoor positioning and navigation purposes. Through fair comparison of the performance achieve...


Global impact of COVID-19 on stroke care and IV thrombolysis

Nogueira, Raul G.; Qureshi, Muhammad M.; Abdalkader, Mohamad; Martins, Sheila Ouriques; Yamagami, Hiroshi; Qiu, Zhongming; Mansour, Ossama Yassin

Objective: To measure the global impact of COVID-19 pandemic on volumes of IV thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with 2 control 4-month periods. Methods: We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified ...

OBJECTIVES: We aimed to explore the effects of diet on the inflammatory response in middle-aged and elderly people with hypertension. METHODS: Thirty overweight or obese patients with stage one hypertension (age range, 45-75 years) were allocated to either the intervention or control group (n=15 per group; age- and sex-matched). Patients in the intervention group consumed a food powder supplement (100 g) instea...

A fast responsive chromogenic and near-infrared fluorescence lighting-up probe ...

Wu, Juanjuan; Su, Dongdong; Qin, Caiqin; Li, Wei; Rodrigues, João; Sheng, Ruilong; Zeng, Lintao

Thiophenols as high toxic environmental pollutants are poisonous for animals and aquatic organisms. Therefore, it is indispensable to monitor thiophenols in the environment. Herein, a novel near-infrared fluorescent probe was developed for the detection of thiophenols, which was easily prepared by one-step coupling of 2,4-dini trobenzenesulfonyl chloride with Nile blue. The probe showed a significant near infra...

Genomic information is essential for taxonomic, phylogenetic and functional studies to comprehensively decipher the characteristics of microorganisms, to explore microbiomes through metagenomics, and to answer fundamental questions of nature and human life. However, large gaps remain in the available genomic sequencing information published for bacterial and archaeal species, and the gaps are even larger for fu...


Highly-ordered silicon nanowire arrays for photoelectrochemical hydrogen evolut...

Thalluri, Sitaramanjaneya Mouli; Borme, Jerome; Xiong, Dehua; Xu, Junyuan; Li, Wei; Amorim, Isilda; Alpuim, P.; Gaspar, Joao; Fonseca, Helder

Vertically-aligned, highly-ordered silicon nanowire (SiNW) array photocathodes are fabricated employing e-beam lithography followed by deep reactive ion etching (DRIE) of Si. The effect of structural parameters of SiNWs, including wire diameter, length and inter-wire spacing, on their photoelectrocatalytic hydrogen evolution performance has been systematically investigated. Within the range of dimensions under ...


Vapor–solid synthesis of monolithic single-crystalline CoP nanowire electrodes ...

Li, Wei; Gao, Xuefei; Xiong, Dehua; Xia, Fang; Liu, Jian; Song, Wei-Guo; Xu, Junyuan; Thalluri, Sitaramanjaneya Mouli; Cerqueira, M. F.; Fu, Xiuli

Electrochemical water splitting into hydrogen and oxygen is a promising technology for sustainable energy storage. The development of earth-abundant transition metal phosphides (TMPs) to catalyze the hydrogen evolution reaction (HER) and TMP-derived oxy-hydroxides to catalyze the oxygen evolution reaction (OER) has recently drawn considerable attention. However, most monolithically integrated metal phosphide el...


The diagnostic value of narrow-band imaging for early and invasive lung cancer:...

Zhu, Juanjuan; Li, Wei; Zhou, Jihong; Chen, Yuqing; Zhao, Chenling; Zhang, Ting; Peng, Wenjia; Wang, Xiaojing

This study aimed to compare the ability of narrow-band imaging to detect early and invasive lung cancer with that of conventional pathological analysis and white-light bronchoscopy. We searched the PubMed, EMBASE, Sinomed, and China National Knowledge Infrastructure databases for relevant studies. Meta-disc software was used to perform data analysis, meta-regression analysis, sensitivity analysis, and heterogen...

Atomic-layer-deposited ultrafine MoS2 nanocrystals on cobalt foam for efficient...

Xiong, Dehua; Zhang, Qingqing; Li, Wei; Li, Junjie; Fu, Xiuli; Cerqueira, M. F.; Alpuim, P.; Liu, Lifeng

Ultrafine molybdenum sulfide (MoS2) nanocrystals are grown on a porous cobalt (Co) foam current collector by atomic layer deposition (ALD) using molybdenum hexacarbonyl and hydrogen sulfide as precursors. When used to catalyze the oxygen evolution reaction (OER), the optimal Co@MoS2 electrode, even with a MoS2 loading as small as 0.06 mg cm-2, exhibits a large cathodic shift of ca. 200 mV in the onset potential...
