Ultra‐fast organic emulsion‐based synthesis of high‐performance cathode materials for rechargeable batteries

open access: yesBatteries &Supercaps, Accepted Article.
In this work, an emulsion‐based organic synthesis route for the fabrication of cathode materials for rechargeable batteries, which drastically reduces the synthesis time, is presented. In particular, it decreases the times necessary to obtain the pre‐heat‐treatment mixture of oxides down to 4 minutes, markedly faster than the typical times ranging from

The wound healing effect of collagen/adipose‐derived stem cells (ADSCs) hydrogel: In vivo study

open access: yesVeterinary Medicine and Science, Volume 9, Issue 1, Page 282-289, January 2023., 2023
This study evaluated human placental collagen/adipose‐derived stem cells (ADSCs) hydrogel for wound healing in rats. Histopathological analysis revealed that the content of fibroblasts, follicles of the hair, and angiogenesis in collagen/ADSCs group was significantly more than in other groups.

Experimental investigation of strengthening slab-column connections with CFRP fan

open access: yesAin Shams Engineering Journal, 2019
This paper investigates experimentally the punching shear behavior of flat slabs-column connections strengthened with CFRP (Carbon fiber reinforced polymer) string having a fan shape as a new strengthening technique.

Code provisions evaluation for the punching shear capacity of R.C footings without reinforcement for punching shear

open access: yesCase Studies in Construction Materials, 2023
There is no agreement on how to predict punching shear for footings among different design codes, which is inconsistent with experimentally observed capacity. Such inconsistency is due to the following issues: (1) the different definitions used by design

Punching shear strength of steel fibre reinforced lightweight concrete slabs. [PDF]

open access: yes, 1981
One of the problems in slab-column connections is the punching shear failure at over loads. Such failures are sudden and catastrophic, and are undesirable since they do not allow an overall yield mechanism to ...

Numerical modelling of the punching behaviour of steel fibre reinforced self-compacting concrete flat slabs [PDF]

open access: yes, 2013
Punching shear failure on flat reinforced concrete slabs of residential and commercial buildings is generally avoided by using transversal reinforcement and/or chapiters.

Effect of Unbalanced Moment on Punching Shear Strength of Slab-Column Joints [PDF]

open access: yes, 2020
The design of reinforced concrete flat plate slab-column connections subjected to unbalanced moments varies greatly between national design codes. Specific to Canada and the United States (U.S.), assumptions relating to the distribution of unbalanced ...

Implementing NAT Hole Punching with QUIC [PDF]

open access: yesarXiv
The widespread adoption of Network Address Translation (NAT) technology has led to a significant number of network end nodes being located in private networks behind NAT devices, impeding direct communication between these nodes. To solve this problem, a technique known as "hole punching" has been devised for NAT traversal to facilitate peer-to-peer ...

Actin Filament Pointed Ends: Assays for Regulation of Assembly and Disassembly by Tropomodulin and Tropomyosin

open access: yesCytoskeleton, EarlyView.
ABSTRACT Actin filaments are dynamic polymers whose length depends on regulated monomer association and dissociation at their ends. Actin barbed‐end dynamics are relatively better understood, primarily due to the approximately tenfold faster subunit on/off rates at barbed versus pointed ends.
