Biomass derived carbons as electrode materials for supercapacitors have drawn great attention owing to their low cost, high specific areas and abundant surface functional groups, but most of their preparation processes are time-consuming and power-wasting. In this work, we reported a rapid and energy-saving strategy for preparing N/O doped porous carbons derived from loofah sponges for supercapacitors via one-step microwave carbonization/activation. Utilizing KOH as the microwave absorption medium and activator, the microwave carbonization/activation process could be completed within 6-12 min. The resulting loofah sponges derived porous carbons demonstrated a high specific capacitance of 294 F∙g-1 at 0.5 A∙g-1 and an outstanding retention rate of 74.8% at 20 A∙g-1. The fabricated symmetric supercapacitor based on the as-prepared carbon materials displayed a comparable energy density of 6.67 Wh∙kg-1 at the power density of 100 W∙kg-1. Notably, a remarkable long-term cyclic stability by retaining of 95.2% of its initial capacitance was acquired after 60,000 cycles. Our research not only fabricates sustainable electrode materials for supercapacitors but also provides a fast and energy efficient route for producing biomass derived carbon materials with high capacitive performances for commercial applications. © 2024, The Authors.

Nitric oxide(NO) gas therapy has been regarded as a promising strategy for cancer treatment. However,its therapeutic efficiency is still unsatisfying due to the limitations of monotherapy. Previous preclinical and clinical studies have shown that combination therapy could significantly enhance therapeutic efficiency. Herein, a graphene oxide(GO)-L-arginine(L-Arg, a natural NO donor) hybrid nanogenerator is developed followed by surface functionalization of soybean lecithin(SL) for synergistic enhancement of cancer treatment through photothermal and gas therapy. The resultant GO-Arg-SL nanogenerator not only exhibited good biocompatibility and excellent endocytosis ability, but also exhibited excellent photothermal conversion capability and high sensitivity to release NO within tumor microenvironment via inducible NO synthase(i NOS) catalyzation. Moreover, the produced hyperthermia and intracellular NO could synergistically kill cancer cells both in vitro and in vivo. More importantly, this nanogenerator can efficiently eliminate tumor while inhibiting the tumor recurrence because of the immunogenic cell death(ICD) elicited by NIR laser-triggered hyperthermia and the immune response activation by massive NO generation. We envision that the GO-Arg-SL nanogenerator could provide a potential strategy for synergistic photothermal and gas therapy.

The rapid development of electronic technology has exacerbated electromagnetic pollution. It's crucial to develop efficient microwave-absorbing (MA) materials for blocking electromagnetic damage to electronic instruments and human health. However, simple structure MA materials usually have limited microwave absorption capacities and cannot simultaneously meet requirements for lightweight, wide bandwidth, and high loss. Constructing hierarchical structure composites and thereby introducing multiple absorption mechanisms is an effective way to improve the MA performance. In this study, we synthesized an auricularia-shaped MoS2 nanosheet array coated hierarchical multilayer MoS2/PPy/rGO (MPG) composite by a facile hydrothermal method. In the preparation process, using PPy to modify the rGO surface plays a key role, which effectively avoids rGO agglomeration and provides substrates for MoS2 nanosheets to grow on. The thicket of MoS2 nanosheets creates numerous nanoscale interfaces, promoting interface polarization and improving impedance matching. The multilayer heterogeneous structure facilitates multiple reflections and scattering, further attenuating electromagnetic waves. By optimizing the addition of PPy, the material's microstructure and microwave absorption performance were improved. The MPG-10 sample achieved the best reflection loss of -53.5 dB (2.07 mm thickness) and an effective absorption bandwidth of 5.36 GHz (1.82 mm thickness). This work contributes a new idea for the structural design of graphene-based hierarchical heterogeneous microwave absorption materials. © 2023, The Authors. All rights reserved.

The study of non-Fermi liquids sheds light on unconventional phenomena in condensed matter systems that lie beyond the scope of Landau Fermi liquid theory. One intriguing example is the Bose metal, characterized by an uncondensed bosonic ground state. However, constructing a Bose metal phase in two dimensions (2D) remains a significant challenge. Utilizing constraint path quantum Monte Carlo and functional renormalization group methods on a fermionic system with spin anisotropy in a 2D lattice, we reveal the emergence of a Cooper pair Bose metal (CPBM) phase in a highly anisotropic regime (α<0.30) with wide range of filling, as proposed in [A. E. Feiguin et al., Phys. Rev. Lett. 103, 025303 (2009)]. Our findings exhibit a visible nonzero momentum Bose surface in the Cooper-pair distribution function, accompanied by a distinct signal of dxy correlation between pairs. Our results highlight that spin-dependent anisotropy in the Fermi surface leads to versatile pairing forms. Platforms such as ultracold atoms in optical lattices and recently proposed altermagnets hold promise for realizing this intriguing phase.
