This article (DOI: 10.1002/inf2.12380) comprehensively reviews the recent progress in artificial synaptic and spiking neuron devices for neuromorphic computing based on (Hf,Zr)O2‐based ferroelectrics. The actual human brain consists of neurons, axons, and synapses. Simply explain their functions, neurons communicate with each other via electrical events called action potential and chemical neurotransmitters. At the junction between two neurons which is called a synapse, an action potential causes one side of the neuron to release a chemical neurotransmitter. Thus, we intended to mimic the basic element of the human brain and its functions by utilizing our ferroelectric devices. The background consists entirely of two parts (i.e biological neural network (Upper part) and integrated semiconductor chips (Bottom part). In the center of the cover image, we highlighted fluorite‐structured ferroelectrics by emitting lights. It should be noted that the light here is nothing more than intended to emphasize fluorite structure. image

Front cover image: Lignin, the most abundant polyphenolic compound in nature, is emerging as a promising precursor well-suited for carbon fiber production. In article cey2.662, Yan et al. highlights recent advances in lignin valorization into carbon fibers, emphasizing chemical structures, performance, and energy applications. It elucidates manufacturing processes and mechanisms, providing insights into the challenges and prospects of lignin-derived carbon fi bers and enhancing awareness of biomass valorization.

Front cover image: Solar-driven CO2 conversion to solar fuels via semiconductor-photocatalysis is promising, however, it suffers from low selectivity and efficiency due to the lack of desired functionalities of the photocatalyst, and in article number cey2420, Xuezhong Gong et al. demonstrated the selective photoreduction of CO2 to CO using elaborately fabricated ultrathin Bi12O17Cl2 nanosheets, identify the functions of bismuth clusters and oxygen vacancies, elucidate synergetic effect, and provide new research approach for preparing smart multi-functional photocatalysts.

Front cover image: Solar-to-chemical conversion by mimicking natural photosynthesis via g-C3N4 for green energy generation is vital to developing sustainable society and environment. The leaf-like g-C3N4 represents photocatalysts for the production of H2, CO and NH3 chemicals with two origami boats carrying well-separated electrons and holes, respectively, to hinder charge recombination. In article number 10.1002/cey2.252, Wee-Jun Ong and co-workers report the state-of-the-art review of 0D/2D g-C3N4-based photocatalysts to restrain the bottleneck issues of pristine g-C3N4 with auspicious charge separation for applications in water splitting, CO2 reduction and N2 fixation.

Front cover image: Relieving the stress or strain associated with volume change is highly desirable for high-performance SiOx anodes in terms of stable solid electrolyte interphase (SEI)-film growth. In article number 10.1002/cey2.141, Tao et al. demonstrate that the gradient regulation of Si-valence can eliminate the local stress and enhance the lithium-ion transport dynamics for SiOx anode, effectively boosting the cycle life and output power for batteries, and thus strongly driving electric vehicles.

Front cover image: The cover picture shows the selection and theoretical validation of transition metal ions for constructing a new class of cathode material, Na3VFe0.5Ti0.5(PO4)3/C, with NASICON-type structure for SIBs. The combination of V, Fe and Ti elements allows Na+ ions to mobile without stress in the cathode, which results in stable electrochemical characteristics.
