Flexible batteries such as scalable fiber-shaped lithium-ion batteries (FLIBs) hold great potential for powering wearable electronics due to their excellent electrochemical performance, flexibility, and weavability. However, the use of organic liquid electrolytes raises serious safety concerns, including leakage and combustion hazards. In this study, we develop fire-resistant lithium cobalt oxide/graphite FLIBs by employing an in situ polymerized gel polymer electrolyte (GPE) incorporating 1,3,3,5,5-pentafluoro-1-ethoxy-cyclotriphosphazene (PFPN) as a flame retardant and triethylene glycol dimethacrylate (TEGDMA) as a crosslinker.

In the past several years, a few cervical Pap smear datasets have been published for use in clinical training. However, most publicly available datasets consist of pre-segmented single cell images, contain on-image annotations that must be manually edited out, or are prepared using the conventional Pap smear method. Multicellular liquid Pap image datasets are a more accurate reflection of current cervical screening techniques.

Janus transition metal disulfide (TMD) monolayers have two distinct carbon surfaces that break the inherent ground external mirror symmetry. When compared to traditional TMD materials, Janus TMDs not only inherit the advantages of traditional TMDs but also have new characteristics that are different from those of traditional TMDs. This paper describes the development of a stable passive Q-switched ytterbium-doped fiber laser (YDFL) with operating wavelengths of 1032.

Scalable fiber lithium-ion batteries (FLIBs) have garnered significant attention due to huge potential applications in wearable technology. However, their widespread applications have been limited by inadequate cycle and calendar life, primarily due to the high permeability of the encapsulation layer to water vapor in ambient air. To address this challenge, an ultra-high barrier composite tube is developed by blending polytrifluorochloroethylene (PCTFE) with organically modified montmorillonite (OMMT) for the continuous packaging of FLIBs.

Replacement of liquid electrolytes with polymer gel electrolytes is recognized as a general and effective way of solving safety problems and achieving high flexibility in wearable batteries. However, the poor interface between polymer gel electrolyte and electrode, caused by insufficient wetting, produces much poorer electrochemical properties, especially during the deformation of the battery. Here we report a strategy for designing channel structures in electrodes to incorporate polymer gel electrolytes and to form intimate and stable interfaces for high-performance wearable batteries.

MXenes are a class of two-dimensional layered structure ternary metal carbide or/and nitride materials. Recently, the MXene VCT has demonstrated excellent long-term stability, strong saturable absorption, and fast optical-switching capability, used to generate Q-switched and ultrashort pulsed lasers. However, bound-state fiber lasers based on VCT have not been reported yet.

Photovoltaic devices represent an efficient electricity generation mode. Integrating them into textiles offers exciting opportunities for smart electronic textiles-with the ultimate goal of supplying power for wearable technology-which is poised to change how electronic devices are designed. Many human activities occur indoors, so realizing indoor photovoltaic fibers (IPVFs) that can be woven into textiles to power wearables is critical, although currently unavailable.

Accurate registration of lung X-rays is an important task in medical image analysis. However, the conventional methods usually cost a lot in running time, and the existing deep learning methods are hard to deal with the large deformation caused by respiratory and cardiac motion. In this paper, we attempt to use deep learning methods to deal with large deformation and enable it to achieve the accuracy of conventional methods.

Fibre lithium-ion batteries are attractive as flexible power solutions because they can be woven into textiles, offering a convenient way to power future wearable electronics. However, they are difficult to produce in lengths of more than a few centimetres, and longer fibres were thought to have higher internal resistances that compromised electrochemical performance. Here we show that the internal resistance of such fibres has a hyperbolic cotangent function relationship with fibre length, where it first decreases before levelling off as length increases.

Health-related quality of life (HRQOL) of caregivers of children with disabilities (CWD) is important for both children's rehabilitation and caregivers' life, but the corresponding attention is far from enough in mainland China. Thus, we investigated the HRQOL of 170 caregivers and related factors in Shanghai. The 12-item Short Form Health Survey (SF-12) was used to measure HRQOL.

The fate of nanoparticles in the ecological chain of agriculture has been concerned as their potential pollution and biological effect to humans with rapid development and massive emission of nanomaterials. Here, we found that two rice cultivars () have different heavy metal accumulation results in the roots and shoots after 15 days growth. Two rice cultivars (), grown in soil containing magnetite (FeO@NH) nanoparticles and heavy metal simultaneous, showed less Pb uptake in the roots and shoots, compared with that without FeO@NH added.

The inactivation of ribosomal protein S6 kinase 1 (S6K1) recapitulates aspects of caloric restriction and mTORC1 inhibition to achieve prolonged longevity in invertebrate and mouse models. In addition to delaying normative aging, inhibition of mTORC1 extends the shortened lifespan of yeast, fly, and mouse models with severe mitochondrial disease. Here we tested whether disruption of S6K1 can recapitulate the beneficial effects of mTORC1 inhibition in the Ndufs4 knockout (NKO) mouse model of Leigh Syndrome caused by Complex I deficiency.
