As one of the core parts of two-terminal(2 T) monolithic tandem photovoltaics, the interconnecting layers(ICLs) play a critical role in modulating the carrier transport and recombination between the sub-cells,and thus influencing the tandem device performance. Here, for the first time, the relationship between ICLs architecture and 2 T monolithic perovskite/organic tandem device performance has been studied by investigating the change of ICLs composition layer thickness on the ICLs optical and electrical properties, sub-cells EQE properties, and tandem device J-V properties. It is revealed that the ability of ICLs on modulating the sub-cells carrier balance properties is strongly associated with its composited layers thickness, and the tandem device carrier balance properties can be reflected by the relative EQE intensity between the sub-cells. Finally, with a deep understanding of the mechanisms, rational design of ICLs can be made to benefit the tandem device development. Based on the optimized ICL a high PCE of 20.03% is achieved.

Bruning, Harry Department of Environmental Technology Wageningen University and Research PO Box 17 Wageningen6700 AA Netherlands Department of Chemical Engineering and Polymer Science Shahjalal University of Science and Technology Sylhet3114 Bangladesh Department of Environmental Health Engineering School of Public Health Tehran University of Medical Sciences Tehran Iran

The impact of Cl⁻in heat-activated peroxydisulfate (PDS) and peroxymonosulfate (PMS) processes for benzotriazole (BTA) degradation was investigated. Results showed that 0.42 mM BTA could be degraded by PDS and PMS under 70°C in presence and absence of Cl⁻. The PMS-mediated BTA degradation rate increased with increasing Cl⁻ concentration up to 1000 mg/L, while a further increase of Cl⁻ concentration decreased the degradation rate. Cl⁻ inhibited PDS-mediated BTA degradation between 100 to 10,000 mg/L. Radical scavenging experiments indicated that BTA degradation was mainly driven by hydroxyl and sulfate radicals in PDS and PMS systems without Cl⁻. Reactive chlorine species boosted the PMS system for BTA degradation in presence of Cl⁻. pH substantially influenced the PMS system, but not the PDS system, in presence and absence of Cl⁻. By LC-MS/MS analysis, forty-two transformation products (TPs) were identified. Based on the TPs, polymerization, hydroxylation, benzene ring-opening, and carboxylic acid formation were hypothesized to be the main degradation mechanisms in absence of Cl⁻, whereas chlorination, triazole ring-opening, and nitration were the additional degradation steps in presence of Cl⁻. More chlorinated TPs were found in PMS/Cl⁻ system than in PDS/Cl⁻ system, which was also reflected in absorbable organic halides (AOX) and end-product toxicity analyses. The PMS/Cl⁻ process also produced other undesirable by-products, such as chlorates which were not detected in the PDS/Cl⁻ process. This shows that PDS and PMS-based advanced oxidation processes can notably differ in terms of toxic by-product formation,and need to be critically evaluated before applying for organic pollutant degradation under saline conditions. © 2023, The Authors.

Flexible zinc ion batteries (ZIBs) are promising candidate for energy storage devices because of high safety and low cost. Carbon fiber (CF) is an ideal current collector for ZIBs due to its good flexibility, electrical conductivity and corrosion resistance. Herein, a novel CF-based current collector is proposed. At first, the inertness and non-polarity of CF were significantly modified by activating and etching to obtain a multi-layered pore structure. After then, carbonized polypyrrole (CPPy) nanowire conductive networks were built up on etched carbon fiber (ECF) by electrochemical in-situ growing and carbonization. Based on the CPPy network, MnO2 nanoflowers were grown firmly by the hydrothermal method to construct a multilayer MnO2@CPPy@ECF composite electrode. The multi-layered three-dimensional CPPy conductive network is rooted in the interior of MnO2, providing a dedicated transmission path for both electrons and ions during electrochemical redox reactions. The MnO2@CPPy@ECF electrode had an initial capacity of 346.1 mAh·g-1 at 0.1 A·g-1 and 252.8 mAh·g-1 after 800 cycles. In addition, the integrated flexible Zn-MnO2 2D fabric battery with MnO2@CPPy@ECF fabric cathode shows a specific capacity of 254.7 mAh·g-1 at 0.1 A · g-1. Finally, a flexible Zn-MnO2 yarn battery with unique structural advantages of high flexibility, shape adaptability, structural integrity and good mechanical stability was fabricated by the 2D braid method. The initial specific capacity of the flexible Zn-MnO2 yarn battery is 111.7 mAh·g-1 at 0.1C, and the coulomb efficiency reaches more than 98%. This work opens up a new pathway for the rational design of flexible electrodes for wearable ZIBs. © 2023, The Authors. All rights reserved.

In this paper, we develop a novel approach to achieve ultra-high resolution in organic light-emitting diodes (OLEDs) through a photolithography patterning process. It is important to apply a solvent resistant electron transport layer (ETL) in the photolithography pattering of OLED because of solution coating process of photoresist on the ETL. Therefore, a solvent resistant ETL named 2,7-bis(4,6-diphenyl-1,3,5-triazin-2-yl)-9,9 ′ -spirobi[fluorene] (SBF-Trz) was developed and employed as the ETL of OLEDs. The SBF-Trz demonstrated excellent solvent resistance during photolithography process and enabled device performances comparable to those of the conventional OLED without any photolithography process. It was found that the SBF-Trz ETL is appropriate as the ETL of the OLED patterned by photolithography due to good electron transport property, good stability, and good solvent resistance.

Two-dimensional plastic packaging films provide vital protection during transport and storage of food and other goods, offering significant economic benefits compared to other materials. However, their usage results in a considerable amount of packing waste including multi-materials and multilayer films made of various polymer layers, which are exceptionally difficult to recycle. To promote sustainable material usage, efforts towards recycling of these two‑dimensional materials are essential. This work presents a proof of concept for composition-based mechanical sorting of multilayer plastic films. The use of transflectance near-infrared (NIR) hyperspectral imaging data collected on a laboratory scale sorting line and principal component analysis (PCA) allowed a composition-specific distinction. Besides the separation of multilayers from monolayers, several multilayer classes according to their two major polymer components were identified. In case of two commonly used multilayers, polyethylene-polyamide (PE/PA) and polyethylene-polyethylene terephthalate (PE/PET), further NIR based classification was found and investigated using Raman and attenuated total reflectance Fourier transform infrared (FTIR-ATR) imaging spectroscopy. Cross-section analysis showed that only certain classes within PE/PA multilayers contain ethylene vinyl alcohol, whereas classes within PE/PET showed the presence of polyvinyl alcohol layers and different number of layers. This composition-based sorting method could enhance the recycling potential of multilayer packaging films. © 2025, The Authors. All rights reserved.

In this work, the use of potato fruit juice (PFJ) in combination with poly(3-hydroxybutyrate) (PHB) was explored as a biobased barrier coating on paperboard. A two-layer and three-layer solution were explored. In the two-layer structure, the PFJ layer was rod-coated on pigment-coated paperboard, followed by extrusion coating of PHB on top. In the three-layered coating, paperboard without pigment coating was extrusion-coated with PHB, followed by rod coating of PFJ, and finally, extrusion-coated with PHB. The specific water vapor transmission rate was reduced by approximately 95% and 90% for the two- and three-layer coatings, respectively, relative to the uncoated paperboard. Besides contributing to barrier properties, the PFJ increased the bonding strength between the PHB and the paperboard. Although the three-layer coated paperboards showed better oxygen barrier properties than the two-layered coatings, the oxygen permeability was still high. Three-layer coatings exhibited moderate peeling strength, better creasing properties, and better grease barrier properties compared to two-layered coated paperboards. © 2024, The Authors.

Etching technology - one of the representative modern semiconductor device makers - serves as a broad descriptor for the process of removing material from the surfaces of various materials, whether partially or entirely. Meanwhile, thinning technology represents a novel and highly specialized approach within the realm of etching technology. It indicates the importance of achieving an exceptionally sophisticated and precise removal of material, layer-by-layer, at the nanoscale. Notably, thinning technology has gained substantial momentum, particularly in top-down strategies aimed at pushing the frontiers of nano-worlds. This rapid development in thinning technology has generated substantial interest among researchers from diverse backgrounds, including those in the fields of chemistry, physics, and engineering. Precisely and expertly controlling the layer numbers of 2D materials through the thinning procedure has been considered as a crucial step. This is because the thinning processes lead to variations in the electrical and optical characteristics. In this comprehensive review, the strategies for top-down thinning of representative 2D materials (e.g., graphene, black phosphorus, MoS2, h-BN, WS2, MoSe2, and WSe2) based on conventional plasma-assisted thinning, integrated cyclic plasma-assisted thinning, laser-assisted thinning, metal-assisted splitting, and layer-resolved splitting are covered in detail, along with their mechanisms and benefits. Additionally, this review further explores the latest advancements in terms of the potential advantages of semiconductor devices achieved by top-down 2D material thinning procedures. © 2024 The Royal Society of Chemistry.

This paper presents a comprehensive review on the current state of digital simulation technology and its strategic application usages with a key focus on advanced compression garments. Although three-dimensional(3D) digital garment simulators have significantly impacted the apparel and textile industry, their use has been limited to visual prototyping, quality checking, or marketing. The physical properties of garment simulators have been overlooked in advanced functional manufacturing. This literature review investigates the possibility of strategically utilizing virtual physical properties to enhance garment functions, specifically in wearables and medical-grade compression fields. The first phase of this paper gives an overview of the current state of 3D garment simulation tools and their measurement features. This is followed by a gap analysis between simulated and physical property evaluations, focusing on minimizing the gaps. The literature is thoroughly examined to identify appropriate studies that uses digital tools for compressional garments and add value to wearables and healthcare applications. This paper provides valuable insights for apparel and textile engineers, enabling them to better understand the limitations and capabilities of garment simulators in improving advanced features for specific end users.
