Conformal coating of TiO2 nanorods on a 3-D CNT scaffold by using a CNT film as a nanoreactor: a free-standing and binder-free Li-ion anode

Journal of Materials Chemistry A (2013)

Jianli Cheng Bin Wang Huolin L. Xin Chunjoong Kim Fude Nie

A free-standing and binder-free electrode, which consists of a 3-D conductive scaffold and conformal TiO2 nanorods, is synthesized by using an interconnected CNT film as a nanoreactor. Such a conformal 3-D nanostructure can not only provide the electrodes with fast charge transportation and long-term structural integrity, but also eliminate the heavy metal current collector, polymer binder and conductive additive. The conformal CNT–TiO2 anode demonstrates exceptional electrochemical properties with high capacity, high rate capability and excellent cycling stability. It shows a charge capacity of 129 mA h g−1 after 1000 cycles at 10 C with a low capacity fade of 0.007% per cycle in a half cell. Meanwhile, the CNT–TiO2/LiFePO4 full cell exhibits superior capacity retention with a high Coulombic efficiency of approximately 100% during 400 cycles at 2 C. Such a 3-D conformal nanostructure is promising for application in high-performance energy storage.

Vacancies‐Induced Delocalized States Cobalt Phosphide for Binder‐Free Anode Toward Stable and High‐Rate Sodium‐Ion Batteries

Small (2024)

Heng Zhang Jianli Cheng Xin Xia Lang Qiu Feng Liu

Abstract Metal phosphides with easy synthesis, controllable morphology, and high capacity are considered as potential anodes for sodium‐ion batteries (SIBs). However, the inherent shortcomings of metal phosphating materials, such as conductivity, kinetics, volume strain, etc are not satisfactory, which hinders their large‐scale application. Here, a CoP@carbon nanofibers‐composite containing rich Co─N─C heterointerface and phosphorus vacancies grown on carbon cloth (CoP 1‐x @MEC) is synthesized as SIB anode to accomplish extraordinary capacity and ultra‐long cycle life. The hybrid composite nanoreactor effectively impregnates defective CoP as active reaction center while offering Co─N─C layer to buffer the volume expansion during charge–discharge process. These vast active interfaces, favored electrolyte infiltration, and a well‐structured ion‐electron transport network synergistically improve Na + storage and electrode kinetics. By virtue of these superiorities, CoP 1‐x @MEC binder‐free anode delivers superb SIBs performance including a high areal capacity (2.47 mAh cm −2 @0.2 mA cm −2 ), high rate capability (0.443 mAh cm −2 @6 mA cm −2 ), and long cycling stability (300 cycles without decay), thus holding great promise for inexpensive binder‐free anode‐based SIBs for practical applications.

High-Throughput Design of Two-Dimensional Electron Gas Systems Based on Polar/Nonpolar Perovskite Oxide Heterostructures

Scientific Reports (2016)

Kesong Yang Safdar Nazir Maziar Behtash Jianli Cheng

Abstract The two-dimensional electron gas (2DEG) formed at the interface between two insulating oxides such as LaAlO 3 and SrTiO 3 (STO) is of fundamental and practical interest because of its novel interfacial conductivity and its promising applications in next-generation nanoelectronic devices. Here we show that a group of combinatorial descriptors that characterize the polar character, lattice mismatch, band gap, and the band alignment between the perovskite-oxide-based band insulators and the STO substrate, can be introduced to realize a high-throughput (HT) design of SrTiO 3 -based 2DEG systems from perovskite oxide quantum database. Equipped with these combinatorial descriptors, we have carried out a HT screening of all the polar perovskite compounds, uncovering 42 compounds of potential interests. Of these, Al-, Ga-, Sc-, and Ta-based compounds can form a 2DEG with STO, while In-based compounds exhibit a strain-induced strong polarization when deposited on STO substrate. In particular, the Ta-based compounds can form 2DEG with potentially high electron mobility at (TaO 2 ) + /(SrO) 0 interface. Our approach, by defining materials descriptors solely based on the bulk materials properties, and by relying on the perovskite-oriented quantum materials repository, opens new avenues for the discovery of perovskite-oxide-based functional interface materials in a HT fashion.

Pseudobagrus fui Miao, a valid bagrid species from the Yangtze River drainage, South China (Teleostei: Bagridae)

Zootaxa (2009)

Jianli Cheng J. Andrés López E. Zhang

Pseudobagrus fui Miao is a valid bagrid species that can be separated from all its congeners in having 27–33 anal-fin rays. Among the species of Pseudobagrus, it forms part of a group of approximately 20 species putatively characterized by having a smooth anterior margin of the pectoral-fin spine and short maxillary barbels not extending to the base of the pectoral-fin spine. Pseudobagrus fui, together with P. nitidus and P. vachelli, can be differentiated from all other forktailed species of this group by having no fewer than 20 branched anal-fin rays, the posterior end of the anal-fin base posterior to the vertical through the posterior end of the adipose-fin base, and anal-fin base longer than the adipose-fin base. It further differs from P. nitidus in having a gas bladder without beaded lateral and posterior margins, and from P. vachelli in having short maxillary barbels not extending to the base of the pectoral-fin spine. Pseudobagrus fui is currently known from the main stream of the upper Yangtze River and its tributaries, the Min River, Jialing River, Tuo River, Wu River and Chishui River in Sichuan Province, Guizhou Province, and the Chongqing City. The identity and nomenclature of Pseudobagrus nitidus is also discussed.

Improvement of Hyperphagia by Activation of Cerebral I1-Imidazoline Receptors in Streptozotocin-induced Diabetic Mice

Hormone and Metabolic Research (2012)

Hsien-Ching Chung Tingting Yang Mingzhu Chen Min‐Min Chou Jianli Cheng

Imidazoline I₁-receptors (I₁R) are known to regulate blood pressure and rilmenidine, an agonist, is widely used as antihypertensive agent in clinic. However, the role of I₁R in feeding behavior is still unclear. In the present study, we used the agonist of I₁R to investigate the effect on hyperphagia in streptozotocin (STZ)-induced diabetic mice. Rilmenidine decreased the food intake of STZ-diabetic mice in a dose-dependent manner. The reduction of food intake was abolished by pretreatment with efaroxan at the dose sufficient to block I₁R. Intracerebroventricular (icv) administration of rilmenidine into STZ-diabetic mice also significantly reduced hyperphagia, which was reversed by icv administration of efaroxan. In addition, similar results were observed in STZ-diabetic mice, which received chronic treatment with rilmenidine 3 times daily (t.i.d.) for 7 days. Moreover, the hypothalamic neuropeptide Y (NPY) level was reduced by rilmenidine that was also reversed by pretreatment with efaroxan. In conclusion, the obtained results suggest that rilmenidine can decrease food intake in STZ-diabetic mice through an activation of I₁R to lower hypothalamic NPY level.

Engineering Coexposed {001} and {101} Facets in Oxygen-Deficient TiO₂ Nanocrystals for Enhanced CO₂ Photoreduction under Visible Light

ACS Catalysis (2015)

Lianjun Liu Yuqiu Jiang Huilei Zhao Jiatang Chen Jianli Cheng

This work for the first time reports engineered oxygen-deficient, blue TiO2 nanocrystals with coexposed {101}-{001} facets (TiO2–x{001}-{101}) to enhance CO2 photoreduction under visible light. The TiO2–x{001}-{101} material demonstrated a relatively high quantum yield (0.31% under UV–vis light and 0.134% under visible light) for CO2 reduction to CO by water vapor and more than 4 times higher visible light activity in comparison with TiO2 with a single {001} plane or {101} plane and TiO2(P25). Possible reasons are the exposure of more active sites (e.g., undercoordinated Ti atoms and oxygen vacancies), the facilitated electron transfer between {001} and {101} planes, and the formation of a new energy state (Ti3+) within the TiO2 band gap to extend the visible light response. An in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) study was applied to understand the roles of coexposed {001}-{101} facets and Ti3+ sites in activating surface intermediates. The in situ DRIFTS analysis suggested that the coexposed {001}-{101} facets increased the capacity of reversible CO2 adsorption and that the combination of {001}-{101} and Ti3+ enhanced the activation and conversion kinetics of adsorbed species. The visible light responsive TiO2–x{001}-{101} material is not oxidized after long-term exposure to an air environment. This work is a significant contribution to the design of efficient and stable solar fuel catalysts.

High-mobility two-dimensional electron gas in SrGeO₃- and BaSnO₃-based perovskite oxide heterostructures: an ab initio study

Physical Chemistry Chemical Physics (2016)

Yaqin Wang Wu Tang Jianli Cheng Safdar Nazir Kesong Yang

We explored the possibility of producing a high-mobility two-dimensional electron gas (2DEG) in the LaAlO3/SrGeO3 and LaGaO3/BaSnO3 heterostructures using first-principles electronic structure calculations. Our results show that the 2DEG occurs at n-type LaAlO3/SrGeO3 and LaGaO3/BaSnO3 interfaces. Compared to the prototype LaAlO3/SrTiO3, LaAlO3/SrGeO3 and LaGaO3/BaSnO3 systems yield comparable total interfacial charge carrier density but much lower electron effective mass (nearly half the value of LaAlO3/SrTiO3), thus resulting in about twice larger electron mobility and enhanced interfacial conductivity. This work demonstrates that SrGeO3 and BaSnO3 can be potential substrate materials to achieve a high-mobility 2DEG in the perovskite-oxide heterostructures.
