Computational screening and descriptors for the ion mobility in energy storage materials

open access: yes
Ion mobility in electrolytes and electrodes is a critical factor influencing the performance of batteries. Low ion mobility is for example one of the major factors reducing the range of battery-electric vehicles in winter time.

Nanospray desorption electrospray ionization (nano-DESI) mass spectrometry imaging with high ion mobility resolution

open access: yes, 2023
Untargeted separation of isomeric and isobaric species in mass spectrometry imaging (MSI) is challenging. The combination of ion mobility spectrometry (IMS) with MSI has emerged as an effective strategy for differentiating isomeric and isobaric species ...

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Discerning ambiguous internal fragment assignments that are generated in top-down mass spectrometry with cyclic ion-mobility enhances protein sequence information

open access: yes, 2023
Top-down mass spectrometry (TD-MS) has become a central technique for the analysis of intact proteins, and internal fragments (fragments containing neither the C- nor N-terminus) have been utilized to enhance the sequence information extracted from such ...

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

open access: yesAdvanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

Mass Spectrometry Investigation of Some ATP-Binding Cassette (ABC) Proteins

open access: yesMedicina
Drug resistance remains one of the main causes of poor outcome in cancer therapy. It is also becoming evident that drug resistance to both chemotherapy and to antibiotics is driven by more than one mechanism.
