Abstract A rational design for oxygen evolution reaction (OER) catalysts is pivotal to the overall efficiency of water electrolysis. Much work has been devoted understanding cation leaching and surface reconstruction very active electrocatalysts, but little on intentionally promoting in a controlled fashion. We now report controllable anodic Cr CoCr 2 O 4 by activating pristine material at high potential, which enables transformation inactive spinel into highly catalyst. The depletion...
Direct foaming from solids is the most efficient method to fabricate porous materials. However, ideal fails prepare aerogel of nanoparticles because plasticity their denied by overwhelming interface interactions. Here, we invent a hydroplastic directly convert graphene oxide into bulks and microarrays, replacing prevalent freezing method. The water intercalation plasticizes enables direct instead catastrophic fragmentation. bubble formation follows general crystallization rule allows...

Herein, we present electro-oxidation formate, catalyzed iron-substituted lanthanum cobaltite (LaCo1−xFexO3). The Fe/Co ratio in oxides...
Glycerol is a byproduct of biodiesel production and can be low-cost source for some high-value C1-C3 chemicals. The conversion achieved by photo-, thermo-, electro-catalysis methods. electrocatalytic oxidation method attractive due to its moderate reaction conditions high electron product efficiency.

Water oxidation on magnetic catalysts has generated significant interest due to the spin-polarization effect. Recent studies have revealed that disappearance of domain wall upon magnetization is responsible for observed oxygen evolution reaction (OER) enhancement. However, an atomic picture pathway remains unclear, i.e., which benefits most from spin-polarization, adsorbent mechanism, intermolecular mechanism (I2M), lattice oxygen-mediated one, or more? Here, using three model with...
Developing technologies based on the concept of methanol electrochemical refinery (e-refinery) is promising for carbon-neutral chemical manufacturing. However, a lack mechanism understanding and material properties that control e-refinery catalytic performances hinders discovery efficient catalysts. Here, using 18 O isotope–labeled catalysts, we find oxygen atoms in formate generated during reaction can originate from catalysts’ lattice O-2p-band center levels serve as an effective...
Modern large language models (LLMs) often encounter communication bottlenecks on current hardware, rather than purely computational constraints. Multi-head Latent Attention (MLA) tackles this challenge by using low-rank matrices in the key-value (KV) layers, thereby allowing compressed latent KV states to be cached. This approach significantly reduces cache size relative traditional multi-head attention, leading faster inference. Moreover, MLA employs an up-projection matrix increase...
