A strategy to develop a nutrient-rich hybrid food using rice grains functionalized with nanocoating and bovine cells for a sustainable food system is reported. Rice grains are safe food ingredients with a low incidence of allergy and have a nutritional profile and structure suited for 3D cell culture. An edible coating composed of fish gelatin and food enzymes offers a high affinity between rice grains and cells and improves the structural stability of grains for increased cell capacity. The potential of rice grains as cell scaffolds is demonstrated by investigating the interactions between the coating, grains, and cells. The rice grains are transformed into a hybrid food with animal nutrients by containing organized bovine cells. We discuss the food properties and production value of this rice-based meat to evaluate its potential as a sustainable food that guarantees safety from food crises and global warming.

Supercapacitors (SCs) possess a multitude of prospective uses in fields such as automobiles, power electronics, wearable devices, smart grids, etc., and have been widely concerned because of the advantages of high power density, long cycle life, and high stability. However, the low energy density compared to secondary batteries has become a key factor limiting its wider application. In this study, NiCo-LDH with cation and oxygen vacancies (Vcat,o-NiCo-LDH) were prepared by alkali etching and cyclic voltammetry, to maximize the synergistic impact of these vacancies and enhance supercapacitor performance. In addition to increasing the number of active sites and specific surface area and facilitating the adsorption and transport of electrolyte ions, the introduction of cation and oxygen vacancies also causes structural reorganization induced by an electric field, which regularizes the shape of nanosheets and improves performance. The results show that the Vcat,o-NiCo-LDH electrode has a remarkable specific capacitance of 2577 F g-1 at 1 A g-1. Even under 50 A g-1 after 20,000 charge-discharge cycles, it maintains 95.7% cycle stability and exhibits excellent Coulomb efficiency. The asymmetric SC device assembled by Vcat,o-NiCo-LDH, and activated carbon works stably in a voltage window of 2.0 V, and the specific capacitance approaches 196.5 F g-1 at 1 A g-1. The study has shown that the Vcat,o-NiCo-LDH electrode has excellent cycle stability, high power density, and high energy density for supercapacitors. © 2024, The Authors. All rights reserved.

Hydrogels is a unique material that affordable to apply as a membranes layer. In tropical country, such as Indonesia there is easily found water hyacinth (a weed plant) which is potentially used for hydrogels materials fabrication due to high cellulose content. Carboxymethyl cellulose (CMC) from water hyacinth cellulose and banana peels pectin are used to produce hydrogel for ultrafiltration membrane. The aims of this study are to characterize the functionalization of CMC-pectin membrane with different ratio using Fourier transform infrared spectroscopy (FTIR) and to determines the morphology of its membranes structure. The CMC was synthesized from water hyacinth stems through carboxymethylation. The functionalization group of multiple CMC-pectin membrane ratio is domination with carboxyl group (COO-), carbonyl stretching and carbon group. Meanwhile, CMC-pectin 70:30 wt% ratio displays not smooth structure. There is a water hyacinth stems extracted cellulose fibre on the surface of hydrogel CMC:pectin membrane. In other hand, the addition of pectin in all ratio variation exhibit increasing contact angle number from 63.98° to 68.16° (0-30 wt% pectin). The existence of pectin from banana peels on hydrogel membranes contributes to increase hydrophobicity of hydrogel-membrane, in spite of the contact angle value is below than 90°. 2023 The Authors.

Simultaneous Feature Extraction of Intra- and Inter-Cycle Changes for Knee Point Prediction of Lithium Ion Batteries

Early lifespan prediction is essential in battery prognostics, and data-driven approaches are prevalent. Previous data-driven approaches did not exploit the cyclic non-stationary patterns in the dataset due to the recurring charging and discharging operation. This study proposes a novel method to extract features from intra- and inter-cycle patterns simultaneously by applying a 2D convolutional neural network (CNN) to a data matrix structured in cycle and voltage dimensions. Results using a published partial discharging dataset show that the 2D CNN not only outperformed the 1D CNN and Elastic Net but also enabled a reduction of the input size for an early prediction.

Non-Flammable Electrolyte for Large-Scale Ni-Rich Li-Ion Batteries: Reducing Thermal Runaway Risks

SSRN

SSRN 2023年

We present a novel, non-flammable electrolyte for Ni-rich 18650 cylindrical lithium-ion batteries (LIBs) based on a blend of triethyl phosphate (TEP) and fluorinated ethylene carbonate (FEC). We conducted a comprehensive analysis of the electrolyte, including electrochemical tests, safety evaluations, electrode surface characterizations, and quantum calculations, to elucidate its property-function relationship. We found that combining TEP with a concentrated FEC as a co-solvent (1.2 M LiPF6 in TEP/FEC, 30/70 %v) resulted in a robust solid electrolyte interface (SEI) predominantly composed of lithium fluoride (LiF). This innovation improved the SEI's stability and suppressed electrolyte decomposition during extended cycling, leading to consistent battery performance. Our findings introduce a promising non-flammable electrolyte solution for LIBs that offers both thermal runaway prevention and seamless integration into existing battery manufacturing processes. This positions it as a potential alternative to solid-state electrolytes in advanced battery technology, with the potential to revolutionize the field. © 2023, The Authors. All rights reserved.

Decomposition is a fundamental principle of resolving complexity by scale, which is utilized in a variety of decomposition-based algorithms for control and optimization. In this paper, we aim to give a tutorial review of the following aspects: (i) how to decompose a network representing a control or optimization problem according to its latent block structure, (ii) how decomposition is determined for distributed control, and (iii) how optimization problems are solved under decomposition. Directions for further developing decomposition methods and decomposition-based control and optimization algorithms are also discussed.
