Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Genomic and dietary discontinuities during the Mesolithic and Neolithic in Sicily

open access: yesiScience, 2022
Summary: Sicily is a key region for understanding the agricultural transition in the Mediterranean because of its central position. Here, we present genomic and stable isotopic data for 19 prehistoric Sicilians covering the Mesolithic to Bronze Age ...

The Beixin Culture archaeobotanical evidence from Guanqiaocunnan indicates a population dispersal of hunter-gatherercultivators into and across the Haida region of northern China [PDF]

open access: yes, 2020
The Beixin Culture appears within the hilly southwestern area of the Haidai region of northern China at ca. 5000 BC, and spreads to its north and northeast flood plains in the following millennium, replacing the Houli Culture.

Germanane Quantum Dots Promote Metabolic Reprogramming of Immune Cells Toward Regulatory T Cells and Suppress Inflammation In Vitro and In Vivo

open access: yesAdvanced Functional Materials, EarlyView.
Metabolic changes in immune cells direct the phenotype and function of the host immune system. Smart nanomaterials must target metabolic pathways to direct immune cell fate. This study reports the fabrication and first application of germanane quantum dots (GeHQDs) to modulate inflammation in vitro and in vivo.

Novel Functional Materials via 3D Printing by Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Crops, Cattle and Human DNA – The Motala Site and the Mesolithic-Neolithic Transition in Östergötland, Southern Sweden

open access: yesCurrent Swedish Archaeology, 2016
Palaeogenetic research has recently questioned the notion that the transition to agriculture in south- ern Scandinavia was initiated by local groups of hunter-gatherers who adopted the new economy at the onset of the Neolithic.

Self‐Powered Permeable Electronic Dressing for Exudate Management, Electrostimulation and Drug Delivery in Chronic Wound Healing

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a self‐powered permeable electronic dressing (SPED) that synergistically integrates exudate management, electrical stimulation, and on‐demand drug delivery. The dressing effectively absorbs exudate while demonstrating potent antibacterial activity and accelerated tissue regeneration in diabetic mouse models, thereby promoting ...
