Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

SMaRT Stacking: A Methodology to Produce Optimally Layered EMI Shields with Maximal Green Index Using Fused Deposition Modeling

open access: yesAdvanced Functional Materials, EarlyView.
Electromagnetic interference (EMI) shields consisting of polylactic acid (PLA) in layers with different concentrations of multiwalled carbon nanotubes (MWCNT) are produced using additive manufacturing. The permittivity function of layers with different filler concentrations is learned using data of homogeneous and randomly ordered shields.

Observation of $\chi_{c2}\to\eta'\eta'$ and $\chi_{c0,2}\to\eta\eta'$

open access: yes, 2017
Using a sample of $447.9\times 10^6$ $\psi(3686)$ events collected with the BESIII detector in 2009 and 2012, we study the decays $\chi_{c0,2}\to$ $\eta'\eta'$ and $\eta\eta'$. The decays $\chi_{c2}\to\eta'\eta'$, $\chi_{c0}\to\eta\eta'$ and $\chi_{c2}\to\eta\eta'$ are observed for the first time with statistical significances of $9.6\sigma$, $13.4 ...

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production

open access: yesAdvanced Functional Materials, EarlyView.
Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

Amorphous High Entropy Alloy Nanosheets Enabling Robust Li–S Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Amorphous ultrathin FeCoNiMoW high entropy alloy nanosheets are incorporated into the polypropylene separator of lithium‐sulfur batteries, enhancing their capacity, rate performance, and cycling stability. Abstract High‐entropy alloys (HEAs) show great potential for catalyzing complex multi‐step reactions, but optimizing their parameters, i.e ...

Search For The $X\Left(2370\Right)$ And Observation Of ${\Eta }_{C}\To \Eta \Eta \Eta \Prime $ In $J/\Psi \To \Gamma \Eta \Eta \Eta \Prime $

open access: yes, 2021
Using a sample of $1.31×{10}^{9}\text{}\text{}J/\psi $ events collected with the BESIII detector, we perform a study of $J/\psi \to \gamma \eta \eta {\eta }^{\prime }$ to search for the $X\left(2370\right)$ and ${\eta }_{c}$ in the $\eta \eta {\eta }^{\prime }$ invariant mass distribution. No significant signal for the $X\left(2370\right)$ is observed,

Search for eta and eta ' invisible decays in J/psi -> phi eta and phi eta '

open access: yes, 2013
Using a sample of (225.3 +/- 2.8) x 10(6) J/psi decays collected with the BESIII detector at BEPCII, searches for invisible decays of eta and eta ' in J/psi -> phi eta and phi eta ' are performed. Decays of phi -> K+K- are used to tag the eta and eta ' decays.
