Fe-rich X-ray amorphous material records past climate and persistence of water on Mars

open access: yesCommunications Earth & Environment
X-ray amorphous material comprises 15-73 wt.% of sedimentary rocks and eolian sediments in Gale crater. This material is variably siliceous and iron rich but aluminum poor.

Screening of maillard reaction substrates from roasted flaxseed and comparative analysis of the antioxidant potential of their products

open access: yesFood Chemistry: X
The antioxidant potential of Maillard reaction products (MRPs) derived from hot-pressed flaxseed oil was investigated through model reactions. Roasting flaxseed at 180 °C for 20 min yielded oil with enhanced oxidative stability.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

open access: yesAdvanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Microbial aspects of the formation of malodorous compounds in anaerobically stored piggery wastes

open access: yes, 1978
In modern intensive animal farming labour-saving waste handling systems are applied. As such, slatted floors have found wide application. In this system large amounts of malodorous wastes are stored in pits under the slatted floors, resulting in the ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Evaluation of anti-melanogenic activity of Ziziphus jujuba fruits obtained by two different extraction methods [PDF]

open access: yesResearch Journal of Pharmacognosy, 2016
Background and objectives: Dried pulps and peels of Ziziphus jujuba fruits are commonly applied as food because of their high nutritional value. It has been widely used in traditional medicine as laxative, tonic, wound healing agent and appetizer.

Formation and properties of whey protein fibrils

open access: yes, 2011
Protein fibrils are threadlike aggregates that are about one molecule thick and more than thousand molecules long. Due to their threadlike structure they could potentially be used to form meat-like structures.
