In most of the past studies on disposal of waste plastic, due to the irreversible hazards for human environmental health (incineration), and the strict requirements of reaction conditions (pyrolysis, gasification), the cost of disposal and research also increases. In this study, we converted waste polyethylene (PE) plastic into high value-added organic products by high-temperature water (HTW) to obtain C1 to C5 short-chain fatty carboxylic acids (formic acid, acetic acid, propionic acid, butyric acid and valeric acid). In addition, the reaction parameters (temperature, time, oxidant amount, pH) were investigated under hydrothermal conditions, and the yield for PE to short-chain fatty acids (C1 -C5) was optimized to 20%. Then the concentration of TOC and IC in the solution was used to measure the conversion and degradation of PE. In addition, the oil phase and solid residue after the reaction were also discussed in this research.

In this White Paper we present the potential of the Enhanced X-ray Timing and Polarimetry(eXTP) mission for determining the nature of dense matter; neutron star cores host an extreme density regime which cannot be replicated in a terrestrial laboratory. The tightest statistical constraints on the dense matter equation of state will come from pulse profile modelling of accretion-powered pulsars, burst oscillation sources, and rotation-powered pulsars. Additional constraints will derive from spin measurements, burst spectra, and properties of the accretion flows in the vicinity of the neutron star. Under development by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Sciences, the eXTP mission is expected to be launched in the mid 2020 s.

Photovoltaic technology with low weight, high specific power in cold environments, and compatibility with flexible fabrication is highly desired for near-space vehicles and polar region applications. Herein, we demonstrate efficient low-temperature flexible perovskite solar cells by improving the interfacial contact between electron-transport layer (ETL) and perovskite layer. We find that the adsorbed oxygen active sites and oxygen vacancies of flexible tin oxide (SnO 2 ) ETL layer can be effectively decreased by incorporating a trace amount of titanium tetrachloride (TiCl 4 ). The effective defects elimination at the interfacial increases the electron mobility of flexible SnO 2 layer, regulates band alignment at the perovskite/SnO 2 interface, induces larger perovskite crystal growth, and improves charge collection efficiency in a complete solar cell. Correspondingly, the improved interfacial contact transforms into high-performance solar cells under one-sun illumination (AM 1.5G) with efficiencies up to 23.7 % at 218 K, which might open up a new era of application of this emerging flexible photovoltaic technology to low-temperature environments such as near-space and polar regions.

The nonlinear chiroptical properties of chiral metal halide perovskite has attracted substantial attention in recent years. In order to overcome the inherent limitations of metal halide, such as high costs, potential toxicity, challenges with recycling, especially the limited laser-induced damage threshold (LDT), we have successfully constructed the first chiral metal-free anti-perovskite, with the aim of utilizing it in second harmonic generation-circular dichroism (SHG-CD). Moreover, the anti-perovskite composed entirely of small organic ions typically display a more extensive transparent window, which could contribute a high LDT. Herein two chiral metal-free anti-perovskites, R / S -MCN [( R / S -MBA) 6 Cl(NH 4 Cl 6 )] were constructed, and exhibit strong second-harmonic generation response from 800 to 980 nm. The second-order nonlinear optical coefficient of the chiral metal-free anti-perovskite reaches 0.89 pm/V, which is higher than that of commercial Y-cut quartz. Most importantly, both R - and S -MCN exhibit a large nonlinear optical activity with a high SHG dissymmetry factor ( g SHG-CD ) of 0.60 and a high laser-induced damage threshold of 71 mJ/cm 2 , which is higher than that of most reported chiral perovskites. Our findings indicate that chiral metal-free anti-perovskite have the potential to be a valuable addition to the development of next-generation nonlinear chiroptical devices.

Nanomedicine holds considerable promise for advancing cancer therapy, however, effective delivery of drugs to solid tumors remains a challenge due to rapid systemic clearance and inefficient cellular uptake. Herein, we have developed a novel charge-reversible nanogel to deliver paclitaxel (PTX) dimers (DPP) with enhanced stability and targeting precision. The nanogels exhibit a dynamic charge-reversal mechanism responsive to the acidic tumor microenvironment (TME), optimizing the cellular uptake of prodrugs. In the high glutathione (GSH) conditions within cancer cells, the disulfide bonds in the DPP are cleaved, resulting in the intracellular release of active PTX and reduced drug toxicity to normal cells. In vivo pharmacokinetic studies revealed an extended plasma elimination half-life for the charge-reversible nanocarriers, and antitumor efficacy studies demonstrated superior tumor suppression with minimal systemic toxicity. This research underscores the potential of integrating charge-reversal and responsive release mechanisms into one nanocarrier system, balancing the long circulation and high tumor cell internalization capacity of the nanocarrier, and providing a promising strategy for targeted delivery of nanomedicine.

The fictive temperature ( T f ) is widely applied to understand the relaxation thermodynamics of a glass; however, its atomic structural origin is still unclear. Here, we report two novel AZnP 3 O 9 glasses obtained by melting the composition identical single crystals. These glasses exhibit structural inheritance within 5 Å from the single crystal counterparts that is quantified by δ = n glass / n cry (0≤ δ ≤1, n is the number of pair correlation functions). Among the available glass-formers, glass KZnP 3 O 9 exhibits the highest structural inheritance ( δ =1, n glass =8). More insightfully, a reverse correlation between δ and the relaxation thermodynamic parameters is observed in glass AZnP 3 O 9 , revealing for the first time the atomic structural origin of fictive temperature.

Achieving both high power conversion efficiency (PCE) and device stability is a major challenge for the practical development of organic solar cells (OSCs). Herein, three non-fully conjugated dimerized giant acceptors (named 2Y-sites, including wing-site-linked 2Y-wing, core-site-linked 2Y-core, and end-site-linked 2Y-end) are developed. They share the similar monomer precursors but have different alkyl-linked sites, offering the fine-tuned molecular absorption, packing, glass transition temperature, and carrier mobility. Among their binary active layers, D18/2Y-wing has better miscibility, leading to optimized morphology and more efficient charge transfer compared to D18/2Y-core and D18/2Y-end. Therefore, the D18/2Y-wing-based OSCs achieve a superior PCE of 17.73 %, attributed to enhanced photocurrent and fill factor. Furthermore, the D18/2Y-wing-based OSCs exhibit a balance of high PCE and improved stability, distinguishing them within the 2Y-sites. Building on the success of 2Y-wing in binary systems, we extend its application to ternary OSCs by pairing it with the near-infrared absorbing D18/BS3TSe-4F host. Thanks to the complementary absorption within 300–970 nm and further optimized morphology, ternary OSCs obtain a higher PCE of 19.13 %, setting a new efficiency benchmark for the dimer-derived OSCs. This approach of alkyl-linked site engineering for constructing dimerized giant acceptors presents a promising pathway to improve both PCE and stability of OSCs.

For two decades, two-dimensional carbon species, including graphene, have been the core of research in pursuing next-generation logic applications beyond the silicon technology. Yet the opening of a gap in a controllable range of doping, whilst keeping high conductance outside of this gapped state, has remained a grand challenge in them thus far. Here we show that, by bringing Bernal-stacked bilayer graphene in contact with an anti-ferromagnetic insulator CrOCl, a strong insulating behavior is observed in a wide range of positive total electron doping ntotand effective displacement field Deffat low temperatures. Transport measurements further prove that such an insulating phase can be well described by the picture of an inter-layer excitonic state in bilayer graphene owing to electron-hole interactions. The consequential over 1 GΩ excitonic insulator can be readily killed by tuning Deffand/or ntot, and the system recovers to a high mobility graphene with a sheet resistance of less than 100 Ω. It thus yields transistors with "ON-OFF" ratios reaching 107, and a CMOS-like graphene logic inverter is demonstrated. Our findings of the robust insulating phase in bilayer graphene may be a leap forward to fertilize the future carbon computing. © 2021, CC BY.
