Modeling heat transport in nanofluids with stagnation point flow using fractional calculus [PDF]

open access: yes, 2016
This paper studies the flow and heat transfer of power-law type nanofluids with stagnation point flow past a porous sheet. The governing equation of temperature involving spatial fractional derivative is used to investigate the anomalous heat diffusion ...

Thermally Assisted Photocatalytic Dehydrogenation of Methanol in Continuous Steady‐State Operation

open access: yesAdvanced Science, EarlyView.
Thermally assisted photocatalytic methanol dehydrogenation on Pt/TiO2 enables formaldehyde and hydrogen production far beyond thermodynamic limits. Continuous operation delivers up to 95% selectivity over 70 h, and oxygen microdosing strongly boosts conversion by regenerating surface oxygen sites.

MHD nonaligned stagnation point flow of second grade fluid towards a porous rotating disk

open access: yesNonlinear Engineering, 2019
This paper provides analytical solution of the non-aligned stagnation point flow of second grade fluid over a porous rotating disk in the presence of a magnetic field and suction/injection at the disk surface.

Numerical investigation of magnetohydrodynamic stagnation point flow with variable properties

open access: yesAlexandria Engineering Journal, 2016
This article is concerned with the two-dimensional flow of Powell–Eyring fluid with variable thermal conductivity. The flow is caused due to a stretching cylinder. Temperature dependent thermal conductivity is considered.

Real Income Stagnation of Countries, 1960-2001 [PDF]

open access: yes
We examine the phenomenon of real-income stagnation in a large cross-section of countries during the last four decades. Stagnation is defined as negligible or negative growth extending over a number of years.

Engineered Xenogeneic Bone Scaffold with IL‐10 Nanodelivery System: Immunomodulation and BMSC Fate Programming for Skull Defect Repair

open access: yesAdvanced Science, EarlyView.
A multifunctional regenerative composite is constructed by 3D‐printing thermosensitive PNIPAM hydrogel embedded with MPDA@IL‐10 nanoparticles and autologous BMSCs onto antigen‐depleted porcine bone matrix for beagle critical‐sized skull defect reconstruction.

Atomistic Kinetics of Dislocation‐Mediated Grain Growth in Monolayer MoS2

open access: yesAdvanced Science, EarlyView.
Atomic‐resolution in‐situ heating microscopy directly visualizes dislocation‐mediated grain boundary migration and grain growth in monolayer MoS2. Mobile grain boundaries migrate through collective motion of Mo 5|7 dislocations, whereas S 5|7 defects remain largely immobile.

An Injectable Metal‐Drug Supramolecular Condensate Enables Radiosensitization and Systemic Antitumor Immunity for Post‐Surgical Osteosarcoma Therapy

open access: yesAdvanced Science, EarlyView.
This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

Stagnation point flow of viscoelastic nanomaterial over a stretched surface

open access: yesResults in Physics, 2018
Present communication aims to discuss magnetohydrodynamic (MHD) stagnation point flow of Jeffrey nanofluid by a stretching cylinder. Modeling is based upon Brownian motion, thermophoresis, thermal radiation and heat generation.

Deciphering Structure‐Bubble‐Mass Transfer Relationships in Water Electrolysis Through Electrode Morphology Regulation

open access: yesAdvanced Science, EarlyView.
Electrode morphology is shown to govern oxygen‐bubble dynamics and interfacial mass transfer during water electrolysis. Positive‐curvature nanoneedles promote rapid release of small bubbles, sustain electrolyte renewal, and minimize mass‐transport losses, whereas flat and concave architectures increasingly retain bubbles.
