The conversion of CO2 into desirable multicarbon products via the electrochemical reduction reaction holds promise to achieve a circular carbon economy. Here, we report strategy in which modify surface bimetallic silver-copper catalyst with aromatic heterocycles such as thiadiazole and triazole derivatives increase hydrocarbon molecules. By combining operando Raman X-ray absorption spectroscopy electrocatalytic measurements analysis products, identified that electron withdrawing nature...
The aspartic protease cathepsin D, a poor prognostic indicator of breast cancer, is abundantly secreted as procathepsin D by human cancer cells and self-activates at low pH in vitro, giving rise to catalytically active D. Due lower extracellular tumor microenvironments compared normal tissues, may cleave pathophysiological substrates contributing progression. Here, we show yeast 2-hybrid degradomics analyses that cystatin C, the most potent natural inhibitor cysteine cathepsins, both binds...
Polyaniline (PANI) is a candidate for electrocatalysis, and can be combined with metal nanoparticles to fabricate high-performance electrodes electrochemical energy conversion storage. However, its intrinsic properties appear dependent on the synthesis conditions so that from majority of reports, it quite difficult establish an overall performance trend. In this contribution, we report extensive systematic physicochemical screening potentiality chemically synthesized PANI as electrode...
Herein, we report on (31)P(31)P solution-phase "through-space" nuclear spin-spin coupling constants (J(PP)) from a novel family of organometallic tetraphosphine nickel and palladium complexes. These J(PP) were accurately determined through NMR iterative simulation based the second-order spectra obtained for compounds. The corresponding solid-state X-ray structures complexes determined, P.P distances are reported. Due to blocked conformation species in solution, qualitative semiquantitative...
While 17O NMR is increasingly being used for elucidating the structure and reactivity of complex molecular materials systems, much effort still required it to become a routine analytical technique. One main difficulties its development comes from very low natural abundance (0.04%), which implies that isotopic labeling generally needed prior analyses. However, 17O-enrichment protocols are often unattractive in terms cost, safety, and/or practicality, even compounds as simple metal oxides....
Partial galvanic replacement of silver atoms by those gold was optimized to fabricate free-standing highly active and selective electrocatalysts for glycerol electrooxidation.
Additive manufacturing of Polymer-Derived Ceramics (PDCs) is regarded as a disruptive fabrication process that includes several technologies such light curing and ink writing. However, 3D printing based on material extrusion still not fully explored. Here, an indirect approach combining Fused Deposition Modeling (FDM) replica demonstrated simple low-cost to deliver complex near-net-shaped cellular Si-based non-oxide ceramic architectures while preserving the structure. 3D-Printed honeycomb...
Shaping Metal-Organic Frameworks (MOFs) poses a significant challenge for their widespread application on large scale. In particular, precise control over crystal orientation and arrangement substrates are expected to provide exiting opportunities novel materials with customized characteristics enhanced performance in catalysis, gas storage, sensing, optics electronics. Here we demonstrated the first time that microwave irradiation can induce well controlled epitaxial growth of urchin-like...
Mechanically improved polymeric membranes with high ionic conductivity (IC) and good permeability are highly desired for next-generation anion exchange (AEMs) in order to reduce Ohmic losses enhance water management alkaline membrane fuel cells. To move towards the fabrication of such high-performance membranes, creation hydrophilic ion-conducting double gyroid (DG) nanochannels within block copolymer (BCP) AEMs is a promising approach. However, this attractive solution remains difficult...
Recent evidences suggest that plastin/fimbrin is more than a simple actin cross-linking molecule. In this context and based on the fact other members of same family interact with transmembrane proteins, such as integrins, we have investigated possible interaction between L-plastin integrins. By combining coimmunoprecipitation endogenous proteins in vitro techniques solid phase solution assays, demonstrate an additional binding partner for beta-chain integrin confirmed both display some...
The development of reliable production routes for sustainable hydrogen (H2), which is an essential feedstock industrial processes and energy carrier fuel cells. It appears to be unavoidable alternative significantly reduce the dependence on conventional sources based fossil fuels without increasing atmospheric CO2 levels. Among different power-to-X scenarios access high purity H2, electrochemical approach electrolysis parades as a promising solution at either small or large scales. However,...

Abstract Water electrolysis is increasingly considered a viable solution for meeting the world′s growing energy demands and mitigating environmental issues. An inventive strategy to mitigate requirements involves substituting energy‐intensive oxygen evolution reaction (OER) with biomass‐derived glycerol electrooxidation. Nonetheless, synthesis of electrocatalysts controlling selectivity towards added‐value chemicals at anode efficient H 2 generation cathode remains critical bottleneck....

However, integration Ni, Co, P, example, into a nanostructured carbon network develop self‐supporting Ni x Co y P bimetallic limited by several factors, including discrepancy crystal...
Gelsolin is an actin‐binding protein that regulated by the occupancy of multiple calcium‐binding sites. We have studied calcium induced conformational changes in G1–2 and G1–3 sub‐domains, report binding affinities for three type II A new probe G3 has been produced a K d 5 μM measured context G1–3. The two halves gelsolin, G4–6 bind weakly with or without calcium, suggesting once separated apoptotic proteolysis, remain apart allowing to sever actin free manner.
