Abstract Bi 2 WO 6 /TiO 2 nanobelt heterostructures are hydrothermally synthesized from mixtures of Bi(NO 3 ) 3 , Na 2 WO 4 , and TiO 2 nanobelts in ethylene glycol or nitric acid (autoclave, 160 °C, 15 h).

Migration of Phosphorus in Pig Manure During Pyrolysis Process and Slow-Release Mechanism of Biochar in Hydroponic Application

Ruqing Jiang Guangwei Yu Lin‐Hui Yu Yu Wang Changjiang Li

To elucidate the P migration mechanism under conditions of different pyrolysis temperatures of pig manure, sequential fractionation, solution 31P NMR, XPS, XRD, and K-edge XANES techniques were used to analysis the P species in pig manure biochar. The results indicated that most of the organic P in pig manure was converted to inorganic P during pyrolysis, and the transformation to different P groups pathways were clarified. The phase transition from amorphous to crystalline calcium phosphate was promoted, as the temperature was above 600 °C, and the content of P extracted by hydrochloric acid, which was the long-term available P to plant uptake, was significantly increased. The pig manure biochar pyrolyzed at 600 °C can be used as an excellent substitute for P source, providing necessary P species (e.g. water-soluble P, etc.) and metal elements for the growth of water spinach plants, and which were slow-release comparing with Hogland nutrient solution.

A Bi₂WO₆‐Based Hybrid Photocatalyst with Broad Spectrum Photocatalytic Properties under UV, Visible, and Near‐Infrared Irradiation

Advanced Materials (2013)

Jian Tian Yuanhua Sang Guangwei Yu Huaidong Jiang Xiaoning Mu

Near-infrared active photocatalytic properties of Bi2WO6 nanosheets owing to the oxygen vacancies of the Bi2WO6 nanosheets are reported. The broad spectrum photocatalyst, Bi2WO6-TiO2 nanobelt heterostructures, are obtained by assembling Bi2WO6 nanocrystals on TiO2 nanobelts. The active light band of the novel hybrid photocatalyst with high photocatalytic activity covers full-spectrum solar light including the UV, visible, and near-infrared ranges.

X-Pool: Cross-Modal Language-Video Attention for Text-Video Retrieval

arXiv (Cornell University) (2022)

Satya Krishna Gorti Noël Vouitsis W. F. Mader Keyvan Golestan Maksims Volkovs

In text-video retrieval, the objective is to learn a cross-modal similarity function between a text and a video that ranks relevant text-video pairs higher than irrelevant pairs. However, videos inherently express a much wider gamut of information than texts. Instead, texts often capture sub-regions of entire videos and are most semantically similar to certain frames within videos. Therefore, for a given text, a retrieval model should focus on the text's most semantically similar video sub-regions to make a more relevant comparison. Yet, most existing works aggregate entire videos without directly considering text. Common text-agnostic aggregations schemes include mean-pooling or self-attention over the frames, but these are likely to encode misleading visual information not described in the given text. To address this, we propose a cross-modal attention model called X-Pool that reasons between a text and the frames of a video. Our core mechanism is a scaled dot product attention for a text to attend to its most semantically similar frames. We then generate an aggregated video representation conditioned on the text's attention weights over the frames. We evaluate our method on three benchmark datasets of MSR-VTT, MSVD and LSMDC, achieving new state-of-the-art results by up to 12% in relative improvement in Recall@1. Our findings thereby highlight the importance of joint text-video reasoning to extract important visual cues according to text.

[Difference of P content in different area substrate of constructed wetland].

PubMed (2012)

Xue-Ying Cao Yunxiao Chong Guangwei Yu Hai-Tao Zhong

Adsorption of substrate is the main removal mechanisms of phosphorus in constructed wetland. It is easily impacted by various environmental factors existing in the wetland bed. The contents of substrate TP and the main inorganic P in different areas of both horizontal sub-surface flow constructed wetland with plant and one without plant were measured after treating wastewater five months. Different areas of the wetland with plant differed greatly in the substrate TP. Rhizosphere substrate in front area had the highest TP content and achieved 0.75 g x kg(-1), and the TP content of non-rhizosphere substrate in back area was only 0.21 g x kg(-1). The TP content of substrate in different areas of the wetland without plant had a little variety and ranged only between 0.21 and 0.27 g x kg(-1). Averagely, the substrate TP content in the wetland with plant was higher than the one in the wetland without plant. The phosphorous with Fe-bound (Fe-P), Al-bound (Al-P), and Ca-bound (Ca-P) were main inorganic phosphorous existing in the substrate in both wetlands, their contents in different areas substrate all increased, compared with the one before experiment. Fe-P and Al-P in different substrates in both wetlands had a similar variety. Their content between rhizosphere and intermediate substrate of front area in the wetland with plant and other area substrate in both wetlands differed greatly because the former increased greatly. Compared with Fe-P and Al-P, the variety of Ca-P in different substrates in both wetlands was low. But the content of Ca-P in rhizosphere substrate in wetland with plant was higher than other two parts respectively in front and back areas. Obviously, the plant root had an impact on the phosphorous content of substrate in constructed wetland. For TP, Fe-P, Al-P, Ca-P and loosely sorbed phosphorous in substrate, it increased with distance of the root.
