Nickelferrite on Pnictogen Functionalized Carbon Nanohorns. Bifunctional ORR and OER Catalysts in Rechargeable Zinc‐Air Batteries

open access: yesAdvanced Science, EarlyView.
A systematic study on the performance of N,P‐doped NiFe2O4@CNH bi‐functional hybrid electrocatalysts for rechargeable zinc‐air batteries is presented. The importance of P, N‐doping and the intimate tethering of nickel‐ferrite nanocubes on the carbon nano‐horn (CNH) surface which are well dispersed on the surface of N,P doped CNHs.

Applied Archival Downloading with Wget

open access: yesThe Programming Historian, 2013
Archival websites offer a wealth of resources to historians, but increased accessibility does not always translate into increased utility. In other words, while online collections often allow historians to access hitherto unavailable or cost-prohibitive ...

An Injectable and Self‐Reinforced Piezoelectric Hydrogel for Irregular Bone Defects Regeneration: Dynamic Epigenetic Regulation Approach

open access: yesAdvanced Science, EarlyView.
An injectable and self‐reinforcing RSF‐based piezoelectric hydrogel conforms to irregular bone defects and progressively strengthens in situ, overcoming the trade‐off between injectability and mechanical stability. Mechanical loading generates bioelectrical cues that promote P300‐mediated H3K9 acetylation and upregulate PTH1R expression, thereby ...

PRISM, a Bidirectional NMR Foundation Model: From Peak List to Structure and Back

open access: yesAngewandte Chemie, EarlyView.
Structure elucidation from NMR can consume an expert for hours or even days. PRISM addresses this with a bidirectional transformer trained on 1.19 M real experimental spectra: it translates 1H and 13C peak lists into structures with 60.1% stereo‐aware top‐1 accuracy (72.5% stereo‐unaware), and, working in reverse, predicts spectra back from structures,

CXCL3 Antagonism Reverses Systemic Antitumor Immune Memory Impairment Associated With High Tumor Burden and Sensitizes Anti‐PD‐1 Therapy

open access: yesAdvanced Science, EarlyView.
This study reveals that large tumors secrete more chemokine CXCL3, which recruits immunosuppressive neutrophils to the periphery, thereby impairing the activation and memory of systemic tumor‑reactive CD8+ T cells. CXCL3 antagonism restores systemic immune memory and enhances the antitumor efficacy of anti‑PD‑1 therapy, offering a potential strategy to

Scraping Relevant Images from Web Pages without Download

open access: yes, 2023
Automatically scraping relevant images from web pages is an error-prone and time-consuming task, leading experts to prefer manually preparing extraction patterns for a website. Existing web scraping tools are built on these patterns. However, this manual
