Facile Synthesis of CuxS Electrocatalysts for CO2 Conversion into Formate and Study of Relations Between Cu and S with the Selectivity

Advanced Functional Materials, EarlyView.
Copper sulfide based electrocatalysts for CO2 conversion are selective for production of formate as major product. Transformations under electrochemical conditions result in significant sulfur loss, and this study examines the nature of how persistent, residual sulfur (observed as surface SO42– species and S dissolved in the electrolyte) can sustain ...

Dissociative Electron Attachment to the Nitroamine HMX (Octahydro-1,3,5,7-Tetranitro-1,3,5,7-Tetrazocine) [PDF]

Journal of The American Society for Mass Spectrometry, 2013, Volume 24, Issue 5, pp 744-752,, 2016
In the present study, dissociative electron attachment (DEA) measurements with gas phase HMX, octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine, $C_4H_8N_8O_8$, have been performed by means of a crossed electron-molecular beam experiment. The most intense signals are observed at 46 and 176u and assigned to $NO_{2}^{-}$ and $C_3H_6N_5O_{4 ...

Holistic Analysis of Material Properties in Phylogenetically Diverse Spider Silks and Their Influence on Cell Adhesion

Advanced Functional Materials, EarlyView.
Translation of recombinant spider silks as fillers for nerve guidance conduits in long‐segment nerve reconstruction demands a detailed examination of native counterparts. Thus, this study conducts a comprehensive analysis of the material properties of four phylogenetically diverse spider silks and their impact on Schwann cell adhesion, pinpointing key ...

Fibrous Pb(II)‐Based Coordination Polymer Operable as a Photocatalyst and Electrocatalyst for High‐Rate, Selective CO2‐to‐Formate Conversion

Advanced Functional Materials, EarlyView.
A coordination polymer [Pb(tadt)]n prepared by a microwave‐assisted solvothermal method selectively reduces CO2 into formate under visible light with a high apparent quantum yield of ≈25% at 400 nm. It can function as a pre‐catalyst, along with conductive Ketjen Black, to form an active PbCO3/Pb3(CO3)2(OH)2 mixture that exhibits a high Faradaic ...

An Engineered Recombinant Spider Silk Protein Providing Disulfide‐Locked Control over Self‐Assembly and Fiber Formation

Advanced Functional Materials, EarlyView.
Using atomic structure and local stability information, recombinant aciniform spider silk proteins are rationally engineered to incorporate a chemically switchable disulfide bond to prevent fiber formation. When disulfide‐locked, these proteins cannot form continuous fibers, whereas the unlocked (reduced) state can.

Suppression of collision-induced dissociation in a supersonically expanding gas [PDF]

In high-resolution mass spectrometry, an electrospray ionization source is often paired with an ion-funnel to enhance ion transmission. Although it is established that ions experience collision-induced dissociation as they pass through this device, the impact of gas-flow dynamics on ion fragmentation remains unexplored.
