In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

Considering spatiotemporal evolutionary information in dynamic multi‐objective optimisation

open access: yesCAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Preserving population diversity and providing knowledge, which are two core tasks in the dynamic multi‐objective optimisation (DMO), are challenging since the sampling space is time‐ and space‐varying. Therefore, the spatiotemporal property of evolutionary information needs to be considered in the DMO.

The Effectiveness of Psychological Treatment for Anorexia Nervosa in Adolescents: A Critical Review of Randomized Controlled Trials

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Although international treatment guidelines for eating disorders recommend varying psychological approaches for adolescents with anorexia nervosa (AN), most existing reviews have combined adolescent and adult samples, leaving the overall evidence base for this population poorly defined.

Atmosphere‐Regulated Pyrolysis Switches ORR Pathway on Iron‐Based Catalyst for H2O2 Synthesis and Zn‐Air Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Two Fe‐based electrocatalysts with different ORR selectivity were synthesized from a FeMOF in N2 or air atmosphere, which show promising prospects in Zn‐air battery and H2O2 production. Developing simple methods to achieve flexible regulation of oxygen reduction reaction (ORR) selectivity is essential for sustainable energy technologies, yet remains ...

An ant colony genetic fusion routing algorithm based on soft define network

open access: yesIET Networks, EarlyView., 2022
Abstract Aiming at the problem that there are many paths in data forwarding in soft define network (SDN) network, and the optimal path is difficult to find, combined with the advantages of ant colony algorithm and Genetic algorithm (GA), a routing control strategy based on the ant colony genetic fusion algorithm is proposed.

Bis(μ-3,5-dinitrobenzoato-κ2O1:O1′)bis(μ-3,5-dinitrobenzoato)-κ3O1,O1′:O1;κ3O1:O1,O1′-bis[(3,5-dinitrobenzoato-κ2O1,O1′)(1,10-phenanthroline-κ2N,N)dysprosium(III)]

open access: yesActa Crystallographica Section E, 2011
In the binuclear title complex, [Dy2(C7H3N2O6)6(C12H8N2)2], the DyIII ions exhibit a distorted monocapped square-antiprismatic geometry and are coordinated by seven O atoms of four 3,5-dinitrobenzoate (DNBA) anions and two N atoms of a phenanthroline ligand. The carboxylate groups of the DNBA anions exhibit three coordination modes: bidentate chelating,
