direct separating butanol from fermentation broth via pervaporation is considered as the most effective method to realize solvent enrichment, which is dominated by membranes. Herein, MOF (MAF-9) with [sbnd]CF3 group is doped into PdMS matrix to enhance the butanol pervaporation, especially selectivity. The super-hydrophobicity of MAF-9 caused by [sbnd]CF3 groups allows the preferential adsorption and permeation for butanol molecules, thus increasing the membrane selectivity;while its appropriate pore diameter renders the exquisite diffusion pathways towards the butanol molecules, thus increasing the membrane flux. results show that the loading-optimized MAF-9/PdMS MMM has 53 of separation factor and 848 g m−2 h−1 of membrane flux, which are increased by 24% and 16%, respectively, compared with pure PdMS membrane. TGA, FT-Ir, BET, and Xrd are conducted to characterize the thermal stability, morphology and structure of MAF-9;PALS, SEM, AFM, Sd and TGA are tested to evaluate the free volume property, morphology, adsorption capacity and thermal stability of membranes, respectively. Conditions including particle loading, feed temperature and feed concentration are also optimized in this study. © 2021 Elsevier B.V.

Herein, Mg, Ce, and Cu were incorporated into ZIF-8 to improve its Lewis basicity for glycerol carboxylation. Upon metal incorporation, the Ce- and Cu-incorporated ZIF-8 remained structurally intact with slightly increased Lewis basicity, whereas the Mg-incorporated ZIF-8 exhibited a more perturbed structure containing additional exposed N atoms and metal sites (Zn and Mg). The improved Lewis basicity facilitated the increased glycerol conversion of the Mg-incorporated ZIF-8 and its yield of glycerol carbonate in the presence of CH3CN as a homogeneous dehydrating agent. Using NaHCO3 as the heterogeneous dehydrating agent, a much higher selectivity (90%) was obtained over Mg-incorporated ZIF-8 compared to that of CH3CN (∼60% higher), attributed to a high water sorption capability of NaHCO3 that inhibits side reactions. The heterogeneity of NaHCO3 enables efficient recycling (>3 cycles) for repeated catalytic glycerol carboxylation. The results suggested that metal incorporation is an effective and facile approach to improve ZIF-8 Lewis basicity, combined with heterogeneous NaHCO3 as the dehydrating agent, which is beneficial for glycerol carboxylation using CO2 as a feedstock. © 2023 Elsevier Ltd

In recent years, Π-conjugated polymer:fullerene-based bulk heterojunction (BHJ) solar cells have received significant attention since combining a narrow P3HT donor and a high electron affinity PCBM acceptor blend could help achieve high efficiencies. In order to compete with other organic solar cell materials, further optimization of P3HT:PCBM-based BHJ has to be done to improve the device's efficiency.

Fused tapered Fan-in/Fan-out devices of few-mode multi-core fiber have received attentions in recent ten years. Most devices are based on special designed fibers which are called “bridge fiber”. A low insertion loss and low-cost Fan-in/Fan-out device using OM3 fiber as the bridge fiber is fabricated and demonstrated in this paper. The insertion losses of LPOl, LPlla, LPllb, and LP2la are less than 1dB, and the insertion loss of LP2lb and LP02 are 2.02dB and 2.2dB.

Incorporation of photonic material BNNT into the PANI@MgO matrix to boost energy density for supercapacitor application

引用

Materials Today: Proceedings 2023年

作者： Madhuri Sakaray Shilpa Chakra Chidurala Nano-Energy R&D Lab Centre for Nanoscience and Technology University College of Engineering Science and Technology JNTUH Hyderabad Telangana 500085 India

Supercapacitors have garnered significant interest in the realm of electrical energy storage due to their remarkable attributes of high power density and extended cycle life. The electroactive electrode materials embedded within these systems play a crucial role in augmenting both energy density and capacitance. This study presents a novel exploration into the intercalation and distinct characteristics of hexagonal boron nitride (h-BN) within different ratios of MgO/PANI (PANI/MgO/h-BN) composite using a one-pot oxidative polymerization method for supercapacitor applications. The compositional analysis of the composite was comprehensively conducted through techniques such as X-ray diffraction (Xrd), Fourier Transform Infrared spectroscopy (FTIr), Field Emission Scanning Electron Microscopy (FESEM), Cyclic Voltammetry (CV), Galvanostatic Charge-discharge studies (GCd), and Electrochemical Impedance Spectroscopy (EIS). The average crystallite sizes computed for PANI/MgO/h-BN, denoted as A (1:1:1), B (1:1:2), C (1:1:3), and d (1:1:4), were 26 nm, 22 nm, 20 nm, and 18 nm, respectively. The specific capacitance values obtained from GCd were found to be 437F/g, 1609F/g, 1695F/g, and 2105F/g, accompanied by energy densities of 10.1 Wh/kg, 19.3 Wh/kg, 32.2 Wh/kg, and 42.9 Wh/kg, respectively. The outcomes underscore that the composite exhibits a propensity for elevated specific capacitance as the loading capacity of h-BN is escalated, displaying a notable absence of saturation.

In this work, we study the effect of maximum packing fraction of powders on the rheology of geopolymer pastes. A large range of metakaolin powders is generated either by blending or grinding powders. Blends of metakaolin with quartz and limestone are also studied. We show that the compressive packing model is able to predict correctly over a wide range of values the maximum packing fraction of these powders. We show that an increase of the maximum packing of powders leads to a decrease of the viscosity of geopolymer suspension at a constant solid volume fraction. We finally show that the viscosity of studied geopolymer suspensions can be well predicted by the Krieger dougherty relation. We suggest that the highest potential degree of freedom allowing for the control of the viscosity of geopolymer pastes without modifying the composition of the suspension lies in the maximum packing fraction of the solid powders. © 2024, The Authors.

This paper proposes an illumination-robust visual odometry (VO) system that incorporates both accelerated learning-based corner point algorithms and an extended line feature algorithm. To be robust to dynamic illumination, the proposed system employs the convolutional neural network (CNN) and graph neural network (GNN) to detect and match reliable and informative corner points. Then point feature matching results and the distribution of point and line features are utilized to match and triangulate lines. By accelerating CNN and GNN parts and optimizing the pipeline, the proposed system is able to run in real-time on low-power embedded platforms. The proposed VO was evaluated on several datasets with varying illumination conditions, and the results show that it outperforms other state-of-the-art VO systems in terms of accuracy and robustness. The open-source nature of the proposed system allows for easy implementation and customization by the research community, enabling further development and improvement of VO for various applications.

Sweet elephant grass (SEG), a promising bioenergy grass, possesses considerable potential for bioenergy production. However, research on its pretreatment and utilization remains limited. In this study, small quantities of Brønsted acids were introduced to a deep eutectic solvent (dES) comprising choline chloride (ChCl) and glycerol (Gly) for SEG pretreatment. Under mild conditions, a maximum lignin removal rate of 90.08% and a complete hemicellulose removal could be accomplished in the presence of Brønsted acid. Cellulose retention rates consistently above 70% were obtained in all the cases, and a desirable glucose yield up to 94.07% was achieved from the resulting cellulose after further enzymatic hydrolysis. The pretreatment mechanism was elucidated through a combination of characterizations and theoretical calculations, which demonstrated effective disruption of lignin and lignin-carbohydrate complex occurred by the CH···π, HO···H, and Cl···H bond interactions between lignin and dES. Furthermore, the scission of β-O-4 bond was promoted by Bronsted acids in dES. This systematic investigation paves the way for unraveling the mechanism of the efficient pretreatment of lignocellulose in acidic dES. © 2024, The Authors. All rights reserved.
