Solid-state bonding behavior between surface-nanostructured Cu and Au: a molecular dynamics simulation

Scientific Reports, 2022
In recent years, solid-state bonding has attracted attention for various electronic packaging applications as an alternative to conventional solders. Surface-nanostructured materials enable solid-state bonding without complex surface modifications and ...

Visualizing spatially inhomogeneous hydrogen isotope diffusion by hydrogenography

Nuclear Materials and Energy, 2023
We developed a novel, recently patented application of hydrogenography, i.e., the change of the optical properties of certain indicator materials (e.g., yttrium) when these are charged with hydrogen isotopes.

Diffusion with preferential relocation in a confining potential

Journal of Statistical Mechanics: Theory and Experiment
Abstract We study the relaxation of a diffusive particle confined in an arbitrary external potential and subject to a non-Markovian resetting protocol. With a constant rate r, a previous time τ between the initial time and the present time t is chosen from a given probability distribution

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.

Response characteristics of methane–air and propane–air premixed flames to sinusoidal oscillations in equivalence ratio (Effects of Lewis number and preferential diffusion)

Journal of Thermal Science and Technology
Flames propagate in mixture flows with inhomogeneous concentration distributions in practical combustors, such as gasoline direct-injection engines and gas turbine engines. Clarifying the effect of fuel-type differences on the response characteristics of

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Numerical Investigation on the Flame Characteristics of Lean Premixed Methane Flame Piloted with Rich Premixed Flame

Energies
The introduction of the pilot flame can stabilize the lean premixed flame and promote its industrial application. However, the interaction mechanism between the pilot and main flames is complicated.

Oxidation of Au/Ag films by oxygen plasma: phase separation and generation of nanoporosity

Beilstein Journal of Nanotechnology, 2020
The oxidation of Au/Ag alloy thin films using radio-frequency oxygen plasma was studied in this work. It was demonstrated that there is a phase separation occurring between silver and gold.
