Abstract Biomanufacturing is an emerging technology that utilizes living organisms as production tools, with high specificity and selectivity, enabling customized production. Plant cell a typical “factory” of biomanufacturing. Inspired by this, novel bio‐assisted strategy for preparing biomass‐derived carbon@Fe 2 P composites has been proposed. For synthesis, Lemna minor L. chosen chassis plant to absorb Fe 3+ at first, then can be generated in‐situ in biomass during calcination. To reveal the transformation P, fate absorbed evolved. The carbon layers derived from naturalized bioreactors (Lemna cells) effectively constrain disperse synthesized within nanoscale. produced composite exhibits excellent charging‐discharging capability achieve specific capacity (≈340 mAh g −1 ) long cycle life (2000 circles) 1 A . These results demonstrate green synthesis potential high‐capacity fast‐charging anode. This also used prepare other transition metal phosphides (Co Ni 12 5 ). In addition, this combines recovery secondary utilization metals effluent, which meaningful phytoremediation.

Abstract Mimicking the characteristics and achieving specific functions of biological systems is stirring but challenging. Generally, pigments in commercial coating can only achieve a similarity chromaticity, while cannot obtain solar reflective spectrum whose difficulty resides simulating spectral simultaneously. Unfortunately, traditional organic show poor weather heat resistance. Herein, with little difference color (Δ E ab * ), high similarity, as well adjustable green peak similar red edge slope compared common plants (pagoda tree leaf, etc.) 400–2500 nm, also attained. It achieved by interlayer confined pigment Mg/Al‐layered double hydroxide (Mg/Al‐LDH) layers. The corresponding biomimetic leaf displays hyperspectral performance angle cosine 0.9922 resistance at 120 °C. longer than that mechanical mixing demonstrated. intercalated chromophores sodium copper chlorophyllin Mg/Al‐LDH confinement contribute to excellent performance. This work provides requiring same chromaticity plants, filling long‐term use demand gap for weather‐resistant vegetation.

The development of high-energy-density Li-ion batteries is hindered by the irreversible capacity loss during initial charge-discharge process. Therefore, pre-lithiation technology has emerged in past few decades as a powerful method to supplement undesired lithium loss, thereby maximizing energy utilization LIBs and extending their cycle life. Lithium oxalate (Li2C2O4), with high content excellent air stability, been considered one most promising materials for compensation. However, sluggish electrochemical decomposition kinetics material severely hinders its further commercial application. Here, we introduce recrystallization strategy combined atomic Ni catalysts modulate mass transport reaction kinetics. potential Li2C2O4 significantly decreased from ∼4.90V ∼4.30V compatibility current battery systems. In compared bare NCM//Li cell, Ni/N-rGO composite (Ni-LCO) modified cell releases an extra ∼11.7 ​%. Moreover, this ratio can be magnified NCM//SiOx full resulting 30.4 ​% higher reversible capacity. Overall, work brings catalytic paradigm into technology, which opens another window

Abstract Single‐atom catalysts (SACs) with edge‐located metal active sites exhibit superior oxygen reduction reaction (ORR) performance due to their narrower energy gap and higher electron density. However, controllably designing such fully reveal advantages remains challenging. Herein, rich Fe‐N 4 anchored in hierarchically porous carbon nanofibers (denoted as e 1 ‐Fe‐N‐C) are fabricated via an situ zinc‐assisted thermal etching strategy. The ‐Fe‐N‐C catalyst demonstrates alkaline ORR activity compared counterparts fewer commercial Pt/C. Density functional theory calculations show that the accumulation of more negative charges near formation partially reduced Fe state reduce barrier for process. Additionally, unique structures mesopores macropores facilitate full utilization enhance long‐range mass transfer. zinc–air battery (ZAB) assembled has a peak power density 198.9 mW cm −2 , Pt/C (152.3 ). present strategy by facile controlling amount zinc acetate template systematically superiority sites, providing new design avenue rational defect engineering achieve high‐performance ORR.
