Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

open access: yesAdvanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...

Modeling of local scour depth downstream hydraulic structures in trapezoidal channel using GEP and ANNs

open access: yesAin Shams Engineering Journal, 2013
Local scour downstream stilling basins is so complex that it makes it difficult to establish a general empirical model to provide accurate estimation for scour depth. Lack estimation of local scour can endanger to stability of hydraulic structure and can

Effect of Regiochemistry on Doping and Thermoelectric Properties of n‐Doped Fullerene Derivatives

open access: yesAdvanced Electronic Materials, EarlyView.
Three fullerene derivatives doubly substituted with diethylene glycol chains (PDEG‐2) is presented. The different regiochemistry significantly affects the crystallinity and consequently the dielectric properties, electronic transport, and doping efficiency. By striking a balance between compatibility with the molecular dopant N‐DMBI and crystallinity a

Laboratory Study of Local Scour Around an Array of Pile Groups in Clear-Water Scour Conditions

open access: yesJournal of Marine Science and Engineering
Current-induced local scour around pile groups weakens the capacity of structures. In this paper, experimental tests of local scour around an array of 5 × 5 pile groups were conducted in a steady current in a hydraulic flume.

Laparoscopic Colorectal Surgery in the Era of Robotics: Evolution, Eclipse, or Equilibrium?

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Minimally invasive colorectal surgery has undergone a remarkable transformation over the past three decades. Laparoscopy, once viewed with skepticism, is now firmly established as a standard approach, supported by robust randomized trials demonstrating oncologic safety and improved recovery compared to open surgery.

Experimental, Analytical, and Numerical Evaluation of Bridge Pier Scouring

open access: yesCivil and Environmental Engineering
Due to the rising number of incidents of bridge failure, scouring around bridges has received a lot of attention. Accurate scour depth prediction is a challenge for researchers and experts, despite massive global research efforts.

On the influence of apron and cutoff wall configurations on scour protection downstream grade control structures

open access: yesResults in Engineering
Local scour downstream of hydraulic structures poses a major challenge in fluvial engineering, often compromising the stability of river control systems. Falling and impinging jets from Grade Control Structures (GCSs) are key contributors to cavity scour

Internal parasites and association with diarrhoea in sheep at an abattoir in Western Australia [PDF]

open access: yes, 2005
Diarrhoea (scouring) is an important issue for the sheep meat industry. Scouring is a major risk factor for fleece soiling and consequential carcase contamination with microbes that cause meat spoilage and potential dangers for humans (2).

A critical review of porous adsorbents for air separation: From fundamental insights to rational adsorbent design

open access: yesAIChE Journal, EarlyView.
Abstract Air separation via selective adsorption using porous adsorbents offers energy‐efficient alternatives to cryogenic distillation for producing high‐purity O2 and N2. Adsorbent efficacy depends on balancing selectivity, durability, and performance consistency across varying conditions. This comprehensive review critically discusses the design and

Effect of Upstream and Downstream Roughness on Scour Hole of Square Bridge Pile

open access: yesعلوم آب و خاک, 2021
To prevent demolishing bridge piles due to developing the scour hole under the foundation of these piles some solution has been proposed in the literature.
