The methodology of metal‐involved preparation for carbon materials is favored by researchers and has attracted tremendous attention. Decoupling this process and the underlying mechanism in detail are highly required. Herein, the intrinsic mechanism of carbon fixation in graphitic carbon nitride (g‐C3N4) via the magnesium‐involved carbonization process is reported and clarified. Magnesium can induce...
Nacre‐mimetic 2D nanofluidic materials with densely packed sub‐nanometer‐height lamellar channels find widespread applications in water‐, energy‐, and environment‐related aspects by virtue of their scalable fabrication methods and exceptional transport properties. Recently, light‐powered nanofluidic ion transport in synthetic materials gained considerable attention for its remote, noninvasive, and...
The unique feature of nacre‐like 2D layered materials provides a facile, yet highly efficient way to modulate the transmembrane ion transport from two orthogonal transport directions, either vertical or horizontal. Recently, light‐driven active transport of ionic species in synthetic nanofluidic systems attracts broad research interest. Herein, taking advantage of the photoelectric semiconducting...
Conjugated coordination polymers have become an emerging category of redox‐active materials. Although recent studies heavily focus on the tailoring of metal centers in the complexes to achieve stable electrochemical performance, the effect on different substitutions of the bridging bonds has rarely been studied. An innovative tailoring strategy is presented toward the enhancement of the capacity storage...
Single‐pore osmotic power generators show ultrahigh power density. But, when scaling up to real porous materials, their performance drops by orders of magnitude. In article number 1804279, Wei Guo and co‐workers unveil the origin of this giant gap, and point out how to equally achieve kW to MW m−2 power density in membrane‐scale applications.
Nanofluidic blue energy harvesting attracts great interest due to its high power density and easy‐to‐implement nature. Proof‐of‐concept studies on single‐pore platforms show that the power density approaches up to 103 to 106 W m–2. However, to translate the estimated high power density into real high power becomes a challenge in membrane‐scale applications. The actual power density from existing membrane...
In article number 1804688, Lin Jiang and co‐workers fabricate a sensor based on yttrium oxide multi‐shelled hollow structure (YMSHs) for highly selective detection of methanol with ultrasensitive limit (71 ppb). More interestingly, the sensor can also be applied to the liquor sample with ethanol, methanol and water mixtures, which provides a facile way to distinguish methanol from the edible alcohols...
Methanol is extremely harmful to human health, since it is oxidized slowly and can accumulate in the human body. Therefore, it is essential to develop a methanol gas sensing technology with high sensitivity and selectivity for use in environmental monitoring and healthcare. In this work, a simple and low‐cost sensor based on a Y2O3 multishelled hollow structure (YMSH) to selectively detect methanol...
The emerging phosphate species on the surface or near‐surface of electrode materials are versatile and have an intriguing ability for dramatically enhanced electrochemical performance. Unfortunately, the distribution/dispersion of phosphate species still keeps at levels on the exterior not within the interior surface of materials, and the micro‐/nanoscale tuning is commonly rarely concerned and its...
In this paper, for the first time, a laser direct writing technique is reported to form S‐ and N‐doped graphene patterns on thin (0.3 mm thickness) polyethylene terephthalate (PET) and glass substrates from a specially formulated organic polybenzimidazole (PBI) ink, without thermally affecting the substrates and without the need for a metallic precursor. Unlike standard graphene ink printing, postcuring...
A safe, high‐capacity, and long‐life Li metal anode is highly desired due to recent developments in high‐energy‐density Li–metal batteries. However, there are still rigorous challenges associated with the undesirable formation of Li dendrites, lack of suitable host materials, and unstable chemical interfaces. Herein, a carbon nanofiber‐stabilized graphene aerogel film (G‐CNF film), inspired by constructional...
Inhaling a dangerous amount of nanoparticles leads to pulmonary inflammatory and immune disorders, which integrates several kinds of cells. Exosomes are suggested to play a crucial role in intercellular communication via miRNA transmission. To investigate the role of exosomal miRNA in nanoparticle phagocytosis, a total of 54 pneumoconiosis patients along with 100 healthy controls are recruited, exosomes...
The high‐performance electrode materials with tuned surface and interface structure and functionalities are highly demanded for advanced supercapacitors. A novel strategy is presented to conFigure high‐stacking‐density, superior‐roughness nickel manganese layered double hydroxide (LDH) bridged by vertically aligned graphene (VG) with nickel foam (NF) as the conductive collector, yielding the LDH‐NF@VG...
In article number 1701288, by Chang Yu, Jieshan Qiu, and co‐workers, high‐stacking‐density, superior‐roughness layered double hydroxide (LDH) bridged with vertically aligned graphene (VG) is rationally designed and successfully configured. The VG nanosheets are capable of promoting mass and electron transfer, and high‐stacking‐density LDH induces a superior hydrophilic behavior, thus leading to a...
The “Plug and Play” template can be individually or successively grafted by dual‐responsive molecules on the α‐CD modified channels by host–guest interactions and can be peeled off by UV irradiation. The artificial channels present six kinds of responses cycling among four states responding to three environment stimuli, as light, pH, and temperature.
