Turn-Induction in Peptides Incorporating Novel Cyrene-Derived α,α-Disubstituted Amino Acid. [PDF]

open access: yesJ Pept Sci
Novel chiral cyrene‐derived Cyr residues were incorporated into peptides. The α,α‐disubstituted amino acid residue was introduced using the Ugi reaction. X‐ray crystallographic analysis of R‐ and S‐Cyr residues indicated preference to adopt left‐ and right‐handed α‐helical conformations, respectively.

Engaging the public in plant science: Communication facilitators and barriers of scaling up a citizen science campaign

open access: yesPeople and Nature, EarlyView.
Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Effect of Designed 3D Reinforcement in Mitigating Machining Damage on CFRP Plates

open access: yesPolymer Composites, EarlyView.
Effect of Edge Tufting on Surface Quality, Damage, and Mechanical Performance in CFRP Machining: A Comparative Topographical and Structural Analysis. ABSTRACT Composite materials made of carbon fiber‐reinforced epoxy (CFRP) are widely used in aerospace fields due to their high strength‐to‐weight ratio. However, due to low out‐of‐plane resistance, these

Zukunftstechnologien bei der Stromerzeugung: Elektrizität im internationalen Vergleich

open access: yesPhysik in unserer Zeit, EarlyView.
Welche Technologien setzen sich bei der Stromerzeugung gerade durch? Die Antwort sieht man eindeutig in den Trends von weltweiten Stromerzeugungsdaten. Analysiert man diese Daten mithilfe der Theorie der Diffusion von Innovationen, dann zeigt sich, wie Photovoltaik und Wind sich weltweit durchsetzen.

Proteomic Changes in Cancer Cell Lines as a Result of Bacterial Infection

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Bacterial infections have been implicated in shaping the tumor microenvironment (TME), but their effects on cancer cell proteomes remain unexplored. In this study, we analyzed proteomic changes in melanoma (A375) and ovarian cancer (OVCAR3) cell line models following infection with Staphylococcus aureus strain USA300 or Salmonella enterica ...

Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...
