Single-atom catalysts have received significant attention for their ability to enable highly selective reactions. However, many reactions require more than one adjacent site align reactants or break specific bonds. For example, breaking a C–O O–H bond may be facilitated by dual containing an oxophilic element and carbophilic "hydrogenphilic" that binds each molecular fragment. design of stable well-defined dual-atom sites with desirable reactivity is difficult due the complexity...
Abstract Mitochondria are cellular powerhouses that generate energy through the electron transport chain (ETC). The mitochondrial genome (mtDNA) encodes essential ETC proteins in a compartmentalized manner, however, mechanism underlying metabolic regulation of mtDNA function remains unknown. Here, we report expression tricarboxylic acid cycle enzyme succinate-CoA ligase SUCLG1 strongly correlates with genes across various TCGA cancer transcriptomes. Mechanistically, restricts succinyl-CoA...
The incorporation of thermal dynamics alongside conventional optoelectronic principles holds immense promise for advancing technology. Here, we introduce a GaON/GaN heterostructure-nanowire ultraviolet electrochemical cell observing photothermoelectric bipolar impulse characteristic. By leveraging the distinct thermoelectric properties GaON/GaN, rapid generation hot carriers establishes bidirectional instantaneous gradients in concentration and temperature within nanoscale heterostructure...
Abstract Mitochondrial rRNAs play important roles in regulating mtDNA-encoded gene expression and energy metabolism subsequently. However, the proteins that regulate mitochondrial 16S rRNA processing remain poorly understood. Herein, we generated adipose-specific Wbscr16-/-mice cells, both of which exhibited dramatic changes. Subsequently, WBSCR16 was identified as a rRNA-binding protein essential for cleavage rRNA-mt-tRNALeu, facilitating ribosome assembly. Additionally, recruited RNase P...
Catalysts consisting of isolated metal atoms on oxide supports have attracted wide attention because they offer unique catalytic properties, but their structures remain largely unknown the metals are bonded at various, heterogeneous surface sites. Now, by using highly crystalline MgO as a support for sites made from mononuclear organoiridium precursor and investigating species with X-ray absorption spectroscopy, atomic resolution electron microscopy, electronic structure theory, we...
Rhodium gem-dicarbonyl complexes, Rh(CO)2, bonded within the pore structure of zeolite HY and formed by reaction Rh(CO)2(acac) (acac = acetylacetonato) with OH groups on surface were converted in >95% yield to Rh4(CO)12 CO + water at 308 K, process was reversed treatment supported clusters helium 353 K.

The data are supported by density functional theory FEFF near‐edge modelling, together with infrared (IR) spectra. results demonstrate that spectra near the L III (2p 3/2 ) edge provide clearly ascribable, distinctive signatures illustrate effects supports other ligands. This technique is markedly more...
Abstract It is a very urgent and important task to improve the safety high‐temperature performance of lithium/lithium‐ion batteries (LIBs). Here, novel ionic liquid, 1‐(2‐ethoxyethyl)‐1‐methylpyrrolidinium bis(trifluoromethylsulfonyl)imide (PYR 1(2o2) TFSI), was designed synthesized, then mixed with dimethyl carbonate (DMC) as appropriate solvent LiTFSI lithium salt produce an electrolyte high conductivity for safe LIBs. Various characterizations tests show that highly flexible ether group...
Atomically dispersed supported catalysts are drawing wide attention because they offer properties different from those of conventional catalysts, with maximally efficient use the metals. However, performance single-site is often limited by lack neighboring metal centers to cooperate in catalysis. Thus, there motivation extend this class incorporating isolated pairs. We report pairs iridium atoms on MgO initially stabilized support oxygen and cyclooctadiene ligands activated removal latter....
Single-atom alloys (SAAs) have drawn significant attention in recent years due to their excellent catalytic properties. Controlling the geometry and electronic structure of this type localized active site is fundamental technological importance. Dual-atom (DAAs) consisting a heterometallic dimer embedded surface layer metal host would bring increased tunability larger site, as compared SAAs. Here, we use computational studies show that DAAs allow tuning reactivity. Interestingly, combining...
A longstanding challenge in catalysis by noble metals has been to understand the origin of enhancements rates hydrogen transfer that result from bonding oxygen near metal sites. We investigated structurally well-defined catalysts consisting supported tetrairidium carbonyl clusters with single-atom (apical iridium) catalytic sites for ethylene hydrogenation. Reaction and H2 followed O2 led onset activity as a terminal CO ligand at each apical Ir atom was removed bridging dioxygen ligands...
