Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Comparing Hydraulics Between Two Grapevine Cultivars Reveals Differences in Stomatal Regulation Under Water Stress and Exogenous ABA Applications

open access: yesFrontiers in Plant Science, 2020
Hydraulics of plants that have different strategies of stomatal regulation under water stress are relatively poorly understood. We explore how root and shoot hydraulics, stomatal conductance (gs), leaf and root aquaporin (AQP) expression, and abscisic ...

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

open access: yesAdvanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

On‐Demand Activation of Thin Alginate Shell Encapsulated Volatile Liquid for Untethered Pneumatic Soft Actuation

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐changing liquids enable untethered pneumatic actuation in soft robotics but suffer from volatility and storage challenges. This work reports a simple method to encapsulate Novec 7000 within micron‐thin alginate shells via in situ injection and ionic crosslinking.

Hydraulic Power and Hydraulic Machinery [PDF]

open access: yesNature, 1887
THIS work purports to “record existing experience in this branch of engineering.” It is divided into thirty-five short chapters (not numbered, and therefore not quite easy of reference). Five of these treat of general subjects, and the rest of particular machines or details. Hydraulic Power and Hydraulic Machinery. By H. Robinson, M.I.C.E., &c. Pp. xiv.

A dimensional analysis of supersaturated total dissolved gas dissipation [PDF]

open access: yes, 2015
Elevated levels of total dissolved gas (TDG) may occur downstream of dam discharges, leading to increased incidence of gas bubble disease in fish. Accelerating the dissipation of supersaturated TDG in the downstream river can mitigate this negative ...

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Flow characteristics at trapezoidal broad-crested side weir

open access: yesJournal of Hydrology and Hydromechanics, 2015
Broad-crested side weirs have been the subject of numerous hydraulic studies; however, the flow field at the weir crest and in front of the weir in the approach channel still has not been fully described.

Hydraulics of Selected Hydraulic Structures

open access: yes, 2017
Hydraulic structures are human-made systems interacting with surface runoff in urban and rural environments including structures to assist storm water drainage, flood mitigation, coastal protection, or enhancing and controlling flows in rivers and other water bodies.

Branching principles of animal and plant networks identified by combining extensive data, machine learning, and modeling

open access: yes, 2020
Branching in vascular networks and in overall organismic form is one of the most common and ancient features of multicellular plants, fungi, and animals.
