Advanced Microfluidic‐Based Wearable Electrochemical Sensors for Continuous Biochemical Monitoring

open access: yesAdvanced Electronic Materials, EarlyView.
Microfluidic‐based wearable electrochemical sensors are transforming non‐invasive health monitoring through real‐time biochemical analysis of sweat, saliva, and interstitial fluid. This review explores advances in microfluidic design, fabrication, and sensor integration while addressing biofluid variability, material compatibility, and scalability.

Numerical Investigation of Nonisothermal Reversed Stagnation-point Flow [PDF]

open access: yesarXiv, 2013
This thesis investigates the nature of the development of two-dimensional laminar nonisothermal flow of an incompressible fluid close to the reversed stagnation-point. Proudman and Johnson (1962) \cite{proudman1962boundary} first studied the flow and obtained an asymptotic solution by neglecting the viscous terms. This is not practice in neglecting the

Topological structures in the Husimi flow [PDF]

open access: yes, 2015
We study the topological properties of the quantum phase space current in the Husimi representation, focusing on the dynamical differences, induced by these properties, between the quantum and the classical flows. We show that the zeros of the Husimi function are stagnation points of the current and have a nonzero topological charge.

Microstructure of Lithium Metal Electrodeposited at the Steel|Li6PS5Cl Interface in “Anode‐Free” Solid‐State Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Reservoir‐free cells do not use lithium metal during cell preparation. Instead, lithium is electrodeposited during the initial charging step, potentially simplifying the manufacturing of solid‐state batteries. The electrochemical properties of the electrodeposited lithium layer are governed by its morphology and microstructure. However, little is known

MHD stagnation point flow toward a linearly-stretching thermally-insulated sheet with induced magnetic field [PDF]

open access: yesarXiv, 2016
The equations governing the magnetohydrodynamic stagnation point flow toward a non-conducting, thermally insulated, nonporous, linearly stretching sheet are cast in a self similar form. Consistent boundary conditions on the velocity, magnetic field and temperature are invoked. The flow problem involves three parameters- the magnetic Prandtl number, the

Hydrogeological feasibility of mine water deep geological storage in Baotashan coarse sandstone: A case study in Ordos Basin

open access: yesDeep Underground Science and Engineering, Volume 1, Issue 2, Page 148-164, December 2022., 2022
We conducted a new approach of mine water‐deep geological storage, the results showed that the hydrogeological feasibility of Baotashan coarse sandstone (BCS) was impressive and useful for real project. The effective porosity of BCS aquifers ranged from 1.36% to 3.46% and the capacity of mine water geological storage was 0.455–1.266 Mm3 for 1 km2 in ...

Group classification of steady two-dimensional boundary-layer stagnation-point flow equations [PDF]

open access: yesarXiv, 2010
Lie symmetry group method is applied to study the boundary-layer equations for two-dimensional steady flow of an incompressible, viscous fluid near a stagnation point at a heated stretching sheet placed in a porous medium equation. The symmetry group and its optimal system are given, and group invariant solutions associated to the symmetries are ...

MHD THREE-DIMENSIONAL STAGNATION-POINT FLOW OF A MICROPOLAR FLUID [PDF]

open access: yes, 2011
The steady three-dimensional stagnation-point flow of an electrically conducting micropolar fluid in the absence and in the presence of a uniform external electromagnetic field (E0,H0) is analyzed and some physical situations are examined. In particular,

Does Contract Farming Improve Diet Quality? The Case of Senegalese Smallholders

open access: yesAgribusiness, EarlyView.
ABSTRACT The institution of contract farming has gained prominence in most developing countries owing to its numerous benefits. While several studies have already highlighted the welfare benefits of contract farming, very few have investigated the effects on diet quality, despite poor quality diets being a serious challenge in most parts of the ...

Experimental Data on Stagnation-Point Gas Injection Cooling on a Hemisphere-Cone in a Hypersonic Arc Tunnel [PDF]

open access: yes
Exploratory tests were made to determine the reduction of heat transfer resulting from ejection of gases at the stagnation point on a hemisphere-cone at a nominal Mach number of about 9 and at stagnation enthalpies up to 1600 BTU per pound.
