Here, we present a facile ice-confined strategy for achieving high-quality CsPbBr₃ PeMCs in pure water. In this method, lecithin protected PeMCs exhibited remarkable stability in polar solvents (water, ethanol, and acetone), which is due to the strong binding between lecithin and lead ions of PeMCs. Moreover, artificial optical synaptic transistors based on CsPbBr₃ PeMCs were successfully prepared. The devices successfully simulated visual functions by modeling important synaptic features such as excitatory postsynaptic currents, paired-pulse facilitation, spiking-rate-dependent plasticity, spiking-number-dependent plasticity and short-term memory to long-term memory transition.

This paper presents a comprehensive techno-economic analysis (TEA) and life cycle analysis (LCA) of GHG emissions, comparing conventional ethane-based ethylene plants with three decarbonization approaches. The study was conducted within the context of the U.S. average, with sensitivity analysis to identify key drivers affecting well-to-gate (WTG) GHG emissions and the levelized cost of ethylene (LCOE). The conventional plant exhibited a GHG emission of 869 kgCO₂e per tonne-ethylene and a LCOE of $746 per tonne-ethylene. Substituting external natural gas fuels with grid or renewable electricity decreased the emissions to 806 and 717 kgCO₂e per tonne-ethylene, respectively. The emissions of the grid-powered or renewable-powered electrically heated cracker that exports co-produced hydrogen to substitute conventional gray hydrogen were 1031 and −163 kgCO₂e per tonne-ethylene, respectively. The application of CCS to purge gas showed 703 and 514 kgCO₂e per tonne-ethylene emissions, respectively. The electric cracker showed lower emissions than the conventional plant below 380 kgCO₂e per MW h electricity upstream, and at 60 kgCO₂e per MW h, it achieved carbon neutrality.

The compartmentalization of pathways or enzymes within organelles is increasingly recognized for its potential to eliminate metabolic crosstalk and enhance pathway efficacy in terpenoid production. However, the physicochemical environment of a given organelle may not meet the requirements for multiple enzymes. Here, a cytoplasmic-peroxisomal spatial-combination strategy was developed in <em>Candida tropicalis</em> to enhance terpenoid production. This strategy involved compartmentalizing the pathway from acetyl-CoA to mevalonate (MVA) within the cytoplasm and the subsequent steps from MVA to terpenoids within the peroxisome. Furthermore, we demonstrated that the pathway developed in this study is more effective because it provides optimal conditions for enzymes, and the use of the peroxisome membrane as a barrier to concentrate farnesyl diphosphate and geranylgeranyl pyrophosphate within the organelle. Additionally, we observed that this strategy efficiently enhanced productivity and was applicable to sesquiterpenoid, diterpene, and tetraterpenoid biosynthesis. Finally, under 5-L fed-batch fermentation, the titers of β-carotene and miltiradiene reached 9.9 g L⁻¹ and 4.2 g L⁻¹, respectively.

Deep cement decarbonization can be achieved if limestone calcination is replaced with an ambient-temperature electrochemical process. A big challenge of this process is the significant deposition of the Ca(OH)₂ product on the membrane, causing unacceptable operational durability and energy efficiency. To address this issue, we designed a two-chamber membrane-based cement clinker precursor electrolyzer. The electrolyte pH modulation and its effect on decarbonization, precipitation, and cell voltage are investigated. We reveal a thin Ca(OH)₂ layer on the anode side of the membrane under fast decarbonization kinetics (99% current efficiency) at a pH of 5.1, increasing the cell voltage by 50%. A periodic pH change using intermittent stirring ensures a relatively constant voltage level with a sacrifice of ∼3% decarbonization efficiency. Membrane clogging is extremely significant in the cathode chamber due to the extreme pH environment (12.4), causing an inferior production rate of Ca(OH)₂ (59% of the theoretical limit). Introducing Ca²⁺ into the catholyte leads to a much lower pH (11.8) and a clean membrane throughout the electrolysis, increasing the current efficiency for Ca(OH)₂ production to 84%.

Herein, to address the abovementioned technical barriers, we proposed an electron mediator-free bioelectrocatalytic system that integrated electrochemical NADH regeneration and enzymatic reactions. The proposed system was based on a novel, orderly assembled composite bioelectrode composed of a conjugated structure of covalent organic frameworks (COFs, namely, TpBD), which encapsulated cofactor-dependent oxidoreductases. The as-prepared composite bioelectrode was further applied to the highly selective hydrogenation of furfural to furfuryl alcohol. Results indicated that the electron pathway involved in the TpBD conjugated structure guaranteed effective cofactor regeneration on the composite bioelectrode without the assistance of costly electron mediators, thereby promoting the enzymatic reduction of furfural. A high furfural conversion of 98.94% was realized, accompanied by remarkable furfuryl alcohol selectivity of 90.13% at −1.4 V (<em>vs.</em> Ag/AgCl). The novel composite bioelectrode also showed good stability and reusability. Up to 88.1% of the original furfuryl alcohol selectivity was preserved after 10 cycles of recycling.
