Harnessing Natural Wood Architecture: A Self‐Supporting, Hierarchically Porous NiFe@Carbon Capacitive Anode Enhances Electricity Generation and Storage in Microbial Fuel Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study reports a mild “Zn(NO3)2 interlayer‐expansion” strategy combined with electrodeposition to produce a self‐supporting capacitive anode (NiFe@PC) that preserves the wood's native low‐tortuosity channels. The retained native architecture expands niches for microbial colonization.

Synergistic Integration of Electronic Structure Modulating and Hierarchical Mass Transport Channels in Wood‐Derived Electrocatalysts for Efficient Oxygen Evolution

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
By combining electronic structure modulation and hierarchical channel construction, a wood‐derived Cr‐Co2P@PNC/PCW electrocatalyst is developed. This multicomponent synergistic modulation strategy significantly improves the efficiency of OER. Designing synergistic regulation strategies is widely recognized as an effective approach to enhancing ...

Integrated miRNA-seq and functional analyses reveal the regulatory role of sha-miR-92a_L + 2R + 4 via targeting vegfaa in rainbow trout (Oncorhynchus mykiss) responding to acute hypoxia and reoxygenation stress

open access: yesBMC Genomics
Background Hypoxia negatively affects the behavior, growth, reproduction and survival of fish, causing serious economic losses to aquaculture. Rainbow trout (Oncorhynchus mykiss), an important economic fish worldwide, belongs to a hypoxia-sensitive fish ...

An Excellent Deep‐Ultraviolet Nonlinear Optical Crystal Realized via a Functional Group Based on a Two‐in‐One Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A “two‐in‐one” design strategy integrating guanidinium and carboxyl functional groups was developed to overcome the intrinsic trade‐off among SHG response, ultraviolet cutoff edge, and birefringence in DUV NLO crystals. Benefiting from non‐π‐conjugated electronic isolation, Zn‐GPA(II) simultaneously achieves a strong SHG response (2.1 × KH2PO4), an ...

Practical Preimage Attacks on 3-Round Keccak-256 and 4-Round Keccak[r=640, c=160]

open access: yesIACR Transactions on Symmetric Cryptology
Recently, linear structures and algebraic attacks have been widely used in preimage attacks on round-reduced Keccak. Inherited by pioneers’ work, we make some improvements for 3-round Keccak-256 and 4-round Keccak[r=640, c=160].

Polarization‐Reoriented Piezocatalysis Enables Plastic Upcycling with Mechanical Energy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mixed plastic waste remains difficult to upcycle selectively under mild conditions, and piezocatalysis has been constrained by a persistent see‐saw effect: Stronger piezoelectric polarization tends to divert charge carriers away from the very active sites that drive catalysis. Sha et al.

Practical Preimage Attack on 5-Round Keccak[r=640, c=160]

open access: yesIACR Transactions on Symmetric Cryptology
Internal differential cryptanalysis has recently yielded a series of new results in the preimage cryptanalysis of round-reduced Keccak. While these existing attacks share a similar high-level framework, they differ in their technical details. This paper
