Corrosion Inhibition of C38 Steel in 1 M HCl: A Comparative Study of Black Pepper Extract and Its Isolated Piperine

open access: yesInternational Journal of Electrochemical Science, 2010
Corrosion inhibition effect of black pepper (BP) extract and its piperine isolated from BP on corrosion of C38 steel in 1 M HCl solution was investigated by weight loss method. Piperine was isolated by ethanol in yield 6 from ground BP.

Structural and mechanical properties of radiofrequency N2/H2cold plasma-nitrided C38 carbon steel [PDF]

open access: yesThe European Physical Journal Applied Physics, 2011
C38 carbon steel has been nitrided by radiofrequency cold plasma discharge with the aim to study the effect of gas composition on structural and mechanical properties of nitrided substrates. The plasma nitriding was carried out on unheated substrates, using two different gas mixtures (75% N 2 /25% H 2 and 25% N 2 /75% H 2 ) for 8 h of plasma treatment.

ERRATA: "THERMODYNAMIC STUDY OF CORROSION AND INHIBITOR ADSORPTION PROCESSES ONTO C38 STEEL/PIPERAZINES/PHOSPHORIC ACID SYSTEMS" [PDF]

open access: yesSurface Review and Letters, 2009
This paper describes the inhibition effect of 1-benzyl piperazine (P1) and bis(1-benzyl piperazine) thiuram disulfide (P2) towards the corrosion of C38 steel in 5.5 M H3PO4 solution by potentiodynamic polarization and weight loss methods. The influence of inhibitor concentration and temperature on inhibitory behavior of P2 were investigated.

Cancer Risk in Patients With Systemic Sclerosis: A Nationwide Cohort Study in South Korea 2004 to 2021

open access: yesArthritis Care &Research, Volume 77, Issue 12, Page 1466-1473, December 2025.
Objective Systemic sclerosis (SSc) is a rare autoimmune disease characterized by tissue fibrosis, vasculopathy, and immune dysregulation. Our objectives were to quantify the overall and site‐specific cancer risks in patients with SSc compared to the general population, examine temporal trends in cancer incidence following SSc diagnosis, and explore ...

Japanese Encephalitis Virus Genotype 5 Infectious Clone and Reporter System for Antiviral Evaluation

open access: yesJournal of Medical Virology, Volume 97, Issue 9, September 2025.
ABSTRACT The recent emergence of Japanese encephalitis virus genotype 5 (JEV5) has raised concerns regarding limited vaccine efficacy. Here, we report the construction of a full‐length infectious cDNA clone of JEV5 using a bacterial artificial chromosome (BAC) system, based on a South Korea isolate, K15P38 strain.

Reaction Chemistry of Zirconocene(II) with Ferrocenyl Carbonyls§

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 14, May 23, 2025.
The reaction behavior of ferrocenyl‐containing aldehyde and ketones towards a stabilised Zr(II) complex is presented. By increasing their steric demand, the typical dimeric metallaoxirane structure could be stepwise dismantled and the carbonyl coordination changed from side‐on to terminal, resulting in a unique Zr(II) compound.

Phosphoinositide Metabolism: Biochemistry, Physiology and Genetic Disorders

open access: yesJournal of Inherited Metabolic Disease, Volume 48, Issue 2, March 2025.
ABSTRACT Phosphatidylinositol, a glycerophospholipid with a myo‐inositol head group, can form seven different phosphoinositides (PItds) by phosphorylation at inositol carbons 3, 4 and/or 5. Over 50 kinases and phosphatases participate in PItd metabolism, creating an interconnected PItd network that allows for precise temporal and spatial regulation of ...
