Authors: Sun Geng , Alexandrova Anastassia N. , Sautet Philippe
Published: November 2019

Alumina supported Pt nanoclusters under a hydrogen environment play a crucial role in many heterogeneous catalysis applications. We conducted grand canonical genetic algorithm simulations for supported Pt8 clusters in a hydrogen gas environment to study the intracluster, cluster-support, and cluster-adsorbate interactions. Two alumina surfaces, α-Al2O3(0001) and γ-Al2O3(100), and two conditions, T = 600 °C, pH2 = 0.1 bar and T = 25 °C, pH2 = 1.0 bar, were considered corresponding to low and high hydrogen chemical potential μH, respectively. The low free energy ensemble of Pt8 is decorated by a medium (2–12 H), respectively, high (20–30 H), number of hydrogen atoms under equilibrium at low μH, respectively, high μH, and undergoes different morphological transformations on the two surfaces. On α-Al2O3(0001), Pt8 is mostly 3D but very fluxional in structure at low μH and converts to open one-layer 2D structures with minimal fluxionality at high μH, whereas on γ-Al2O3(100), the exact opposite occurs: Pt8 clusters present one-layer 2D shapes at low μH and switch to compact 3D shapes under high μH, during which the Pt8 cluster preserves moderate fluxionality. Further analysis reveals a similar Pt–Pt bond length increase when switching from low μH to high μH on both surfaces although morphological transformations are different. Electronic structure analysis shows the existence of bonding interactions between Pt and Lewis acidic Al3+ sites along with the Pt–O interaction, which implies the necessity to include Al neighbors to discuss the electronic structure of small Pt clusters.

Published: November 2019

Fibroblast growth factors (FGFs) play crucial roles in early gonadal development and germ cell maturation of mammals; FGF9 is involved in mammalian testis steroidogenesis. However, the upstream regulators of FGF9 in ovine testosterone biosynthesis remain unknown. Long non-coding RNAs (lncRNAs) are crucial regulators of multiple biological functions that act by altering gene expression. In the present study, we analysed the role of LOC105611671, a lncRNA upstream of FGF9, in Hu sheep steroidogenesis. We found that LOC105611671 expression increased significantly in Hu sheep testes during sexual maturation (P<0.05). Moreover, levels of FGF9 and testosterone were decreased by LOC105611671 knockdown in Hu sheep Leydig cells (LCs). Results of transient transfection and luciferase assays revealed that FGF9 is a functional target gene of oar-miR-26a in ovine LCs. Further functional validation experiments revealed that LOC105611671 regulates testosterone biosynthesis by targeting oar-miR-26a. Overall, the present study describes the expression profile of LOC105611671 during sexual maturation and demonstrates that LOC105611671 modulates FGF9 expression by targeting oar-miR-26a to promote testis steroidogenesis in Hu sheep. Our research provides a new theoretical basis for genetic and molecular research on testosterone biosynthesis in sheep.

Authors: Chen Qian , Yang Songhe , Dong Lei , Cai Siyuan , Xu Jiaju , Xu Zongxiang
Published: November 2019

Two soluble tetraalkyl-substituted zinc phthalocyanines (ZnPcs) for use as anode buffer layer materials in tris(8-hydroxyquinoline)aluminum (Alq3)-based organic light-emitting diodes (OLEDs) are presented in this work. The hole-blocking properties of these ZnPc layers slowed the hole injection process into the Alq3 emissive layer greatly and thus reduced the production of unstable cationic Alq3 (

) species. This led to the enhanced brightness and efficiency when compared with the corresponding properties of OLEDs based on the popular poly-(3, 4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT: PSS) buffer layer. Furthermore, because of the high thermal and chemical stabilities of these ZnPcs, a nonaqueous film fabrication process was realized together with improved charge balance in the OLEDs and enhanced OLED lifetimes.
A new way to construct topological invariants of non-Hermitian systems with the non-Hermitian skin effect*
Authors: Liu J S , Han Y Z , Liu C S
Published: November 2019

The non-Hermitian skin effect breaks the conventional bulk–boundary correspondence and leads to non-Bloch topological invariants. Inspired by the fact that the topological protected zero modes are immune to perturbations, we construct a partner of a non-Hermitian system by getting rid of the non-Hermitian skin effect. Through adjusting the imbalance hopping, we find that the existence of zero-energy boundary states still dictate the bulk topological invariants based on the band-theory framework. Two non-Hermitian Su–Schrieffer–Heeger (SSH) models are used to illuminate the ideas. Specially, we obtain the winding numbers in analytical form without the introduction of the generalized Brillouin zone. The work gives an alternative method to calculate the topological invariants of non-Hermitian systems.

Published: November 2019

Factual material selection is essential in the manufacturing arena with a superior product and minimum cost. This paper highlights on the advanced multi-criteria approaches namely additive ratio assessment (ARAS) and multi-attributive border approximation area comparison (MABAC) methods for the best material selection of a hybrid composite using aluminum (Al) as base material varying different reinforcement weights and recycling with various industrial wastes by stir casting. Al/WCE gives superior tribomechanical properties at lower cost than the other reinforcements. ARAS and MABAC methods are applied, based on the properties and attributes of the hybrid composites, to compare between the computational and experimental results. The results exactly corroborate with the previous research results which authenticate the expediency of these methods during the solving of complex hybrid material selection problems. Out of 48 different samples, the best hybrid composite material obtained by ranking is material number A30 by ARAS approach (rank 1) which is Al+Al2O3 at 12.5% wt. addition and material number A24 (rank 2) which is heat treated 12.5%wt. WCE. But the same A30 is obtained to be rank 5 and A24 is obtained to be rank 1 by MABAC method. A24 is obtained to be the best hybrid composite after the experimentation.

Published: November 2019

The paper examines the influence of dispersion of multi-walled carbon nanotubes on the thermo-physical properties of working fluids used in solar thermal engineering systems. Thermo-physical property evaluation is very vital to evaluate the performance of solar thermal systems. Ethylene glycol and a commercially reachable thermic fluid therminol 62 are preferred as based fluids. Nanofluids are prepared by dispersing 0.1 %, 0.25 %, 0.5 % and 0.1 % weight fraction of surface modified Multi-walled carbon nanotubes. The nanomaterials are surface modified before dispersion in the thermic fluids and extreme care is taken to prevent property deterioration during surface modification. Thermal conductivity of test fluids is evaluated in the temperature range of 100 to 300°C while viscosity is evaluated in the range of 50 to 150°C s. A 15 to 20 % increase in the thermal conductivity is observed with the dispersion of carbon nanotubes. The viscosity is significantly increased in the low-temperature ranges while the change is minimal above 70. The data could be predicted successfully using artificial neural networks.

Published: November 2019

The Electric Discharge Machining is one of the popular non-traditional approaches which has huge utility in industrial sectors, mostly in die-making industries and as well as in bio-medical fields. But more power consumption, evolvement of unhygienic gases, development of non- biodegradable wastes, etc. are some curtail issues, which leads the poor sustainability of the EDM operation. In this approach, transesterified neem is introduced as a new and green dielectric medium of EDM, and its impacts on EDM responses are examined. Here, machining is carried out between 4 A to 10 A ranges of input current, 100 μ-sec to 200 μ-sec of pulse ON time and 10 μsec to 30 μ-sec of pulse OFF time using both kerosene and transesterified neem as a dielectric medium. The responses like MRR, surface roughness, and microscopic views of machined surfaces are analyzed to check the viability of transesterified neem as a dielectric medium of EDM.It is experimentally observed that transesterified neem as a dielectric medium ensured 6.2 % to 15.6 % more removal rate and 12.25 % to 15.45 % less surface roughness than kerosene.

Published: November 2019

A new method, the rule of the mixture is developed for the determination of thermal conductivity (K), allied properties viz.density and the volume of the individual composite coating powders. Optimum coating thickness through steady-state thermal analysis of composite coating (Al2O3+ZrO2·5CaO) applied on cast iron surface is carried out. Also, the thermodynamic behaviour of TGO and bond coat were simulated. The thickness of the topcoat, TGO, and the bond coat was varied independently in the range of 0.1 to 0.04 mm. Results show that topcoat thickness doesn’t have much influence on the heat transfer. However, TGO and the bond coat plays a crucial role in heat transfer study. Maximum heat resistance, 171.47 ºC observed at 1 mm TGO thickness, compared to 88.94 ºC in case of bond coat for the same coating thickness. It is also understood that 1 mm of optimal TGO thickness may be beneficial in the design of thermal barrier composite coating systems.

Published: November 2019

This article presents the results of a systematic comparison of predictions of the thin-walled beam theory and shell theory in the context of bending of elastic thin-walled beams with an open or closed cross-section. The results for shell theory were obtained using FEM and the ABAQUS/Standard program. The bending task of the thin-walled beam was decomposed into the task with a symmetrical and anti-symmetrical loading, so that the bending and torsion of the thin-walled element would be better visible. In order to objectify the comparison, two coefficients characterizing the mutual similarity of functions were introduced: root mean square deviation coefficient determined for the selected cross-section (in relation to the entire contour) and a coefficient determining the maximum relative difference of a given quantity. The comparison was made for both the stress and the displacement state.
