Abstract This study investigates the potential of Tin Slag Polymer Concrete (TSPC) strengthening through confinement using basalt fiber reinforced polymer (BFRP) and aramid fiber reinforced polymer (AFRP) confinement. TSPC short cylindrical column samples have been wrapped with BFRP and AFRP in a single layer (30 mm overlap) using Sikadur-330 epoxy and final samples were coded as TSPC-UC, TSPC-BF and TSPC-AF for unconfined, BFRP and AFRP for confined respectively. After curing for 30 days at room temperature, compressive test has been performed to know the strength, modulus, strain, fracture energy and failure modes of unconfined and confined TSPC. Test result shows that… More >

Abstract Given their numerous functional and architectural benefits, such as improved bearing capacity and increased resistance to elastic instability modes, cold-formed steel (CFS) built-up sections have become increasingly developed and used in recent years, particularly in the construction industry. This paper presents an analytical and numerical study of assembled CFS two single channel-shaped columns with different slenderness and configurations (back-to-back, face-to-face, and box). These columns were joined by double-row rivets for the back-to-back and box configurations, whereas they were welded together for the face-to-face design. The built-up columns were filled with ordinary concrete of good strength. Finite element models were applied,… More > Graphic Abstract

Abstract Ion dynamics and precise control in nanochannels play key roles in biological systems, energy conversation, and environmental engineering. However, the mechanics behaviors of ions and their manipulation mechanism under extreme confinement remain largely unexplored. Biological ion channels acting as life’s transistors can gate simultaneously fast and selective ion transport through atomic-scale filters to maintain vital life functions. This biological inspiration motivates the quest for artificial structures with simultaneous functions of ion selectivity, fast transport and electrical gating at the atomic scale. Here, we experimentally investigate the ion dynamics and electrical manipulation in graphene channels of 3 angstrom size and report… More >

Abstract Dynamics of a single particle suspended in a low-Reynolds-number fluid under spherical confinement was studied numerically. We calculated hydrodynamic mobilities of a sphere, a prolate spheroid, and an oblate spheroid parallel and transverse to particle-cavity line of centres. The mobilities show maximum in the cavity centre and decay as the particle moves towards the no-slip wall. For prolate and oblate spheroids, their mobilities are also affected by the angle between particle's axis of revolution and the particle-cavity line of centres due to particle anisotropy. It was observed that the effect of particle anisotropy becomes stronger as the confinement level increases.… More >

Abstract La pandémie de Covid-19 liée au virus SARSCoV-2 a imposé un confinement mondial des populations en mars 2020. Outre les effets sur la santé publique et la santé physique, la santé mentale et la santé sexuelle ont été impactées. Les projets personnels des individus ont été bouleversés avec un impact sur les projets de couple et notamment de parentalités. La sexualité des individus s’est adaptée, entraînant des changements importants liés à l’isolement et les incertitudes en lien avec la pandémie mondiale. More >

Abstract Cancer is a complex genetic disease hallmarked with a strong competitive capacity in energy and utilization of substances compared to normal cells, which is partially due to the ability to adjust their metabolism in response to environmental changes. During the lifespan of cancer cells, either during carcinogenesis, progress, or metastasis, massive energy and other substances are essential prerequisites, however, the underlying mechanisms are controversial and still remain unclear. Understanding how cancer cells seize much of the energy and other substances than normal cells is of utmost importance for next-generation cancer therapy, along with the finding of novel drug target and… More >

Abstract The responses of dendritic cells (DCs) to the mechanical microenvironment caused by implanted materials are highly correlated to the host immune responses and largely determines the outcome of tissue regeneration [1,2]. In the early stage of the inflammations following injury or implantation, a large amount of fibrin would deposit around the implanted materials and form a microporous fibrous-liked network structure, which can provide mechanical microenvironment with different spatial confinement in dimensions for following recruited DCs. Herein, we have established a useful model by salmon fibrin to mimic the deposited fibrin matrix and found that DCs cultured on or in fibrin… More >

Abstract This paper deals with the performance of concrete specimens confined with different glass fabric reinforcement in organic binder consisting of resins. Three varieties of glass fabrics such as woven roving (WR), chopped strand mat (CSM), and textile reinforcement have been studied in the investigation. Experiments have been conducted on unconfined and confined concrete cylindrical specimens under compression. The effect of number of layers on confinement has been studied for specific cases. Specimens have been tested under displacement control. It is observed from the experiments that there is an increase in load carrying capacity as well as energy absorption capacity for… More >

Abstract This study was to provide a new aspect of application of shape memory alloys (SMAs) in civil engineering. The high-density polyethylene (HDPE) have been used for construction of pipelines for several years. The main problem of using HDPE for pipes is the joint of two adjacent pipes. In case of having a perfect joint, the HDPE pipeline can bare the internal pressure up to 90 MPa. However, in practice, it can rarely achieve to a perfect pipe joint due to the complicated process, so, it prone to fracture in low internal pressure. To overcome this, this study investigated the efficiency… More >

Abstract Natural rubber (NR), besides being an abundant renewable resource for the elastomer industry, can be a potential resource for the design of innovative biobased polymer networks. The present work is based on "telechelic" liquid natural rubber oligomers obtained by controlled chemical degradation of NR. The chain ends of such oligomers can then be functionalized (with acrylate functions in the present case) and reacted with multifunctional crosslinkers in order to form networks. What's more, the initial solubility of such thermosetting system in an ionic liquid (IL) can be used for the formulation of ionogels. Such solid networks typically containing 80% of… More >
