“…As a result, in recent years more efforts have been focused on renewable sources of electricity, which is any form of energy generated from natural resources (e.g. solar, wind, and biofuels) 4 , 5 . However, the instable productivity of these energy types remains a big challenge in many parts of the world.…”

Lithium ion batteries (LIBs) are at present widely used as energy storage and conversion device in our daily life. However, due to the limited power density, the application of LIBs is still restricted in some areas such as commercial vehicles or heavy-duty trucks. An effective strategy to solve this problem is to increase energy density through the development of battery materials. At the same time, a stable long cycling battery is a great demand of environmental protection and industry. Herein we present our new materials, nitrogen and boron doped carbon layer coated multiwall carbon nanotubes (NBC@MWCNTs), which can be used as anodes for LIBs. The electrochemical results demonstrate that the designed NBC@MWCNTs electrode possesses high stable capacity over an ultra-long cycling lifespan (5000 cycles) and superior rate capability even at very high current density (67.5 A g−1). Such impressive lithium storage properties could be ascribed to the synergistic coupling effect of the distinctive structural features, the reduced diffusion length of lithium ions, more active sites generated by doped atoms for lithium storage, as well as the enhancement of the electrode structural integrity. Taken together, these results indicate that the N, B-doped carbon@MWCNTs materials may have great potential for applications in next-generation high performance rechargeable batteries.

“…The footprint per tube was as small as 1.5 × 10 −4 cm 2 and the power density as high as 257 mW cm −2 , which is three orders of magnitude higher than conventional microsized methanol fuel cells. Liu et al reported a novel glucose biobattery based on the enzyme biocatalysts glucose dehydrogenase, diaphorase, and bilirubin oxidase immobilized in rolled‐up titanium nanomembranes (Figure e) . The device delivers a maximum areal power density of about 3.7 mW cm −2 and a stable power output of about 0.8 mW cm −2 .…”

New amorphous semiconducting materials are involved in the development of flexible electronics based on high-performance compounds that include organic [82] and inorganic (e.g., copper oxide [83] or indium-gallium-zinc oxide (IGZO) [84] ) semiconductor possessing, for instance, the transparency [85] required in optoelectronic applications. Once fabricated on polymeric ultrathin substrates, these devices offer the flexibility, stretchability, and imperceptibility [85][86][87] for onskin (Figure 3 a,b,d) biomedical applications, such as biosensors capable of conformally wrapping a soft or irregularly shaped 3D biological sample such as a cancer cell or a pollen grain. [88] Demonstrating outstanding mechanical stability, thin-film materials, in particular semiconductors, are superior candidates for 3D applications compared to monocrystalline semiconductors. [87,89,90] Good examples are amorphous oxides and some organic molecular semiconductors [82] (Figure 3b-d) which are particularly attractive for 3D self-assembled microelectronics. By employing substrates with a thickness in the micro-and submicrometer range (Figure 3) many issues associated with mechanical stress on the surface could be mitigated, demonstrating the increased robustness and reliability of thinfilm electronics.

Advanced manufacturing techniques offer tremendous potential in electronics, photonics, and biomedicine. Self‐assembly is a powerful strategy for creating three‐dimensional (3D) artificial structures, but existing thin film release techniques have limitations in the relatively complex processes. Herein, a localized laser scribing strategy is proposed to guide the self‐assembly of two‐dimensional thin films into 3D microstructures. It is revealed that laser‐induced heating and momentum can release thin films and roll them into various microstructures. Uniquely, this method allows accurate control of shapes, curvatures, orientations, and sizes for the fabricated rolls. This is a one‐step strategy with no pre‐patterning or post‐drying required. The proposed method represents a significant improvement over existing self‐assembly techniques and may enrich the thin film self‐assembly materials and applications. As proof of concept, the prepared gold micro‐rolls are demonstrated as implanted stents in porcine arteries with impressive flexibility. This study provides a new approach to creating 3D microstructures with simplicity and high repeatability and has significant implications for the future of advanced manufacturing, especially in emerging miniaturized applications, such as invasive robotics, minimized drug delivery, implanted batteries, and nanophotonics.
