Mitochondrial nucleoids or mitochondrial DNA (mtDNA) encodes for a variety of enzymes and proteins that are essential for oxidative phosphorylation, mitochondrial fussion/fission and apoptotic processes. However, visulization of mtDNA dynamics in response to external stumili has not yet been achieved. Herein, we developed a fluorescent probe, named BDP, that is capable of specifically bind to mtDNA

Real-time counting of circulating tumor cells (CTCs) can effectively reduce false-negative results, which, however, is a major stumbling block in the practical CTCs capture process. In this paper, upconversion luminescence is introduced into the inverted microfluidic chip to realize real-time ratiometric luminescence CTCs detection by utilizing its advantage of near-infrared light. In view of the low

Currently, it is still a challenge to endow polymethyl methacrylate (PMMA) with excellent electroconductivity and fire safety. In this work, we have designed a novel hybrid aiming to achieve the flame resistance and electrical conductive of PMMA by fabricating an ordered structure of the FR-PANI@Fe3O4@NC. Employing a magnetic field, the FR-PANI@Fe3O4@NC hybrid shows a beneficial configuration structure

Using block copolymers to improve the mechanical properties of materials was a promising method, and the effect was positively correlated with the aspect ratio of the nanostructures. However, except for worm-like and branched worm-like nanostructures, nanostructures with higher aspect ratios have not been reported so far and its forming methods was unknown. In this paper, a feasible approach was provided

Aqueous energy storage devices hold great promise for smart electric grids and electric vehicles due to their high ionic conductivity, high safety and low cost, but are often limited by electrode materials with rather low voltage window and sluggish mass transport kinetics through thicker electrode materials. Herein, we design a vanadium oxide@molybdenophosphate composite on oxygen-functionalized carbon

Fiber-shaped supercapacitors (FSSCs) are emerging potential power sources for next-generation flexible and wearable miniaturized electronic devices. However, the practical application of FSSCs is hindered by their low energy density due to limited design and constraints in fiber-shaped electrodes production. Herein, a rational design of wet spun MXene (Ti3C2Tx)/PAN fibers derived multichannel porous

Assisting the disabled to speak is a meaningful activity and attracts much attention in the recent years. In this work, an intelligent artificial throat has been realized based on the nanomesh, which can not only emit the sound, but also detect the voice or throat vibration generated by using the electromyogram (EMG)-strain synergetic method. The Au/PVA nanomesh with good thermoacoustic effect can

Exploration of cost effective and high performance electrocatalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is becoming the paramount interest towards the emerging renewable energy technologies such as fuel cells, metal air-batteries and water electrolysers, etc. One of such catalysts is single atom catalyst that exhibits well defined active sites with very high atom

Higher than a standard level, the humidity provides a suitable environment for the pathogenic microorganisms to grow and increases energy consumption for cooling, increasing greenhouse gas emissions. Desiccant air-conditioning (DAC) is an effective method to reduce humidity and energy simultaneously. Conventional desiccants are not suitable for use as a desiccant in building air conditioners, mainly

Acetogenic bacteria (acetogens) are microorganisms with high potential as biocatalysts that can convert C1 gas, such as carbon dioxide (CO2) or carbon monoxide (CO), into biomass or biochemicals; however, high CO concentrations cause growth retardation in these microorganisms. In this study, we performed adaptive evolution of Eubacterium limosum, an acetogen, for approximately 400 generations under

Sugarcane bagasse (SCB), a widely available lignocellulosic by-product, could be potentially used in macrofungal bioconversion for high-value bioactive compounds. For macrofungus with poor lignin degradation capacity, its recalcitrant lignin structure blocked the release of fermentable sugars for cell growth. Herein, the main objective was to construct an effective delignification pretreatment strategy

Chemical gas-liquid absorption systems are one of the most employed technologies for CO2 removal from post-combustion processes, due to the high capture efficiency. This work presents a complex hydrodynamics model used to describe a novel CO2 capture technique that relies on the use of a three phase, gas-solid-liquid absorption column, in which the gas phase acts as the continuous phase, the liquid

Hard carbon (HC) is considered the most promising anode material for sodium ion batteries (SIBs), but still faces urgent challenges such as poor rate capability and low initial Coulombic efficiency (ICE). To improve these issues, herein, we creatively combine membrane science with electrode technology, using phase inversion methods to produce a carbon membrane with a 3D “overpass” hierarchical porous

Here, we developed a polarization-resolved surface plasmon coupling electrochemiluminescence (ECL) strategy based on orientational Au nanobipyramids (Au NBPs) patterned structures. As the surface plasmonic materials, the Au NBPs with large localized electromagnetic field enhancement were used to construct the different patterned structures through the droplet evaporation induced assembly. The distinct
