Constructing type II heterostructures represents a widely recognized strategy for enhancing charge separation and photocatalytic efficiency,but it remains challenging to fabricate homologous heterostructures based on visible-light-responsive semiconductors,especially for popularly investigated （oxy）nitrides with low thermal ***,we synthesized a homologous heterostructure （denoted as YTON＿H） based on the oxynitrides of YTaO4-xNyand YTa *** heterostructure exhibits type II band structure alignment and intimate interface achieved through a magnesium （Mg） powder-assisted nitridation *** with widely reported heterologous heterostructures,the as-obtained YTON＿H homologous heterostructure could similarly exhibit enhanced charge separation as well as photocatalytic water splitting performance with respect to its counterparts(YTaO4-xNyand YTaON2).Meanwhile,detailed structural characterizations and spectroscopy analysis have been made to confirm the formation of heterostructure and promotion of spatial charge separation.

Photocatalytic overall water splitting(OWS)for H2 and O2 evolution with a 2:1 stoichiometric ratio is one of the most promising ways to convert solar energy into chemical one,but it confronts huge challenges in consideration of the uphill water oxidation with four-electron transfer[1].During the past half century,great efforts have been made to the inorganic semiconductors-based photocatalysts,and to date the maximal apparent quantum efficiency(AQE)of OWS under ultra violet(UV)light has reached over 95%,as high as that of natural photosynthesis[2].Comparatively,however,the research on water splitting using conjugated polymers or hybrid metal-organic frameworks(MOFs)for photocatalysts is still in the infancy stage,and the achievement of OWS on them is tremendously limited because of additional challenges in addressing their poor charge separation and photochemical stability[3,4].

The Meso-Cenozoic tectonic attribute of southern China is a continental tridirectional orogenic belt formed by subsynchronous interaction among the Tethys, Northwest Pacific and Kunlun-Qinling tectonic domains. It was created by superimposition of repeated orogenies since the late Permian. The Indosinian folds therein are gentle and localized.

Abstract: The Kazakhstanian plate was near the Tarim, Sino-Korean and South China-Southeast Asian plates in the Middle-late Cambrian and late Ordovician, and approached the Siberian plate in the other periods of the Early Palaeozoic. The Ili and Toksun-Yamansu terranes had been split from the Tarim plate before the Middle Devonian and then went close to Angaraland in the late Early Permian. The Beishan area on the northeastern margin of the Tarim plate came close to Angaraland first in the early Early Permian. The suturing age between the Tarim and Kazakhstanian-Siberian plates is generally the same as that between the Turkey-Central Iran-Gangdise and South China-Southeast Asian plates. The suturing event took place in the early Early Permian, while the corresponding tectogeny occurred between the Early and late Permian.

An Index geographic gossip(IGG)algorithm is proposed. Relay nodes participate in information exchange and updating. The cumulative number of times these nodes participate is characterized by an index number, which can be used to accelerate information updating. The convergence property of the IGG algorithm is theoretically analyzed in ring and grid network topologies. The IGG algorithm improves the standard gossip algorithm by a gain of O(n) in both convergence time and communication cost. Compared to the geographic gossip algorithm, the IGG algorithm has a gain on the order of O(n) and O(n1/2) in the average hop count for information exchange and communication cost, respectively. Finally, the proposed IGG algorithm is compared with various baselines through simulations,and it is shown that significant performance gain can be achieved.

Thrombolytic agents play an important role in the treatment of thrombus diseases. In clinic,traditional thrombolytic agents always resulted in the side effect of systemic thrombolysis because of the shortcomings, such as short half-life, poor specificity of thrombus. Recently, with the development of knowledge of the relationship between their structure and function, a series of new thrombolytic agents were constructed by means of molecular biological techniques. Developing new types of thrombolytic agents is of great significance for more effective treatment of cardiovascular diseases. The latest knowledge of the structure-function relationship of t-PA and u-PA and the progress in development of new thrombolytic agents are reviewed.
