Towards Femtoscan-Assisted Analysis of Liquid Crystal Self-Organization on Different Polymer and Glass Surfaces for Lab-on-a-Chip and Lab-on-a-Dish Applications, Including Optofluidic and Flexoelectric Ones

Received: 27 December 2022;  Published: 29 May 2023;  doi: 10.21926/rpm.2302022


In this paper, starting with an introductory review of the applications of liquid crystals and polymer-dispersed liquid crystal systems in (bio)sensors and microfluidics, the possibilities of visualizing self-organization products of liquid crystalline media or field-induced instabilities of liquid crystalline systems are considered. In particular illustrated cases, it is proposed to use FemtoScan software-containing metrological complexes to visualize instabil [...]

Low-Velocity Impact Resistance of Glass Laminate Aluminium Reinforced Epoxy (GLARE) Composite

Received: 16 June 2022;  Published: 12 May 2023;  doi: 10.21926/rpm.2302021


This study intends to determine the behavior of glass laminate aluminum-reinforced epoxy (GLARE) and glass fiber-reinforced polymer (GFRP) composites under a low-velocity impact test. Experimental tests and numerical simulations are considered for this investigation. All samples are made by the hand lay-up method. Moreover, specimens are produced with a 7075-T6 aluminium sheet with a 0.5 mm thickness, resin 3001, and E-glass fiber. The drop weight test performs the low-velocity impact at 6.7 J a [...]

3D Printing of MXenes-Based Electrodes for Energy Storage Applications

Received: 31 January 2023;  Published: 08 May 2023;  doi: 10.21926/rpm.2302020


Energy storage devices (ESD) including batteries, and supercapacitors are becoming progressively imperative in the transition to a renewable energy future, as they enable the integration of intermittent renewable sources into the grid and provide backup power during outages. There are already reviews available on various energy storage materials and systems. However, the challenges in the choice of suitable materials and fabrication technology are yet to establish for the commercialization of af [...]

Experimental and Analytical Studies of an Ultra-high Performance Concrete Beam Using Carbon Fiber Reinforced Polymer Bars

Received: 10 September 2022;  Published: 04 May 2023;  doi: 10.21926/rpm.2302019


Infrastructure degradation attributable to concrete deterioration and corrosion of reinforcing steel has been a long-standing challenge to the owners and engineers. This problem becomes more evident when concrete structures are subject to aggressively corrosive environments. The use of advanced materials such as ultra-high performance concrete (UHPC) and carbon fiber reinforced polymer (CFRP) bars has a strong potential to overcome this challenge and help build new infrastructure that is durable [...]

Physiological Response of a Natural Central Incisor Tooth to Various Loading Conditions: A 3D Finite Element Study

Received: 05 May 2022;  Published: 24 April 2023;  doi: 10.21926/rpm.2302017


This study evaluates the influence of different loading angles and the area of loading on the ensuing stress distribution and the physical response of a natural central incisor tooth, using a 3D finite element analysis. The CAD model of the incisor tooth assembly (including enamel, dentin, periodontal ligament, pulp, gingiva and jaw bone) was subject to an external (chewing) load of 100 N, over four different areas and at four different angles along the vertical. It was observed that [...]

Evaluating the Performance of Hollow Core Slabs (HCS)-Concrete and Simplifying Their Implementation

Received: 02 March 2023;  Published: 19 April 2023;  doi: 10.21926/rpm.2302016


The largest proportion of the material used in multistory buildings, and thus its carbon impact, is attributed to their slabs being the main contributor of weight. Because of their high strength and concrete self-weight reduction, composite beams with hollow-core slabs were created for their technical and economic benefits, making this system inexpensive and with a reduced environmental impact, thereby lowering carbon emissions. Geometrically, the hollow slab has a sequence of T and [...]

Effect of Heat Treatment on Sliding Wear Resistance of Hybrid Aluminum Matrix Composite

Received: 22 December 2022;  Published: 12 April 2023;  doi: 10.21926/rpm.2302015


Composite materials with aluminum as matrix material have a wider amplitude of large-scale applications in engineering. Some salient features of aluminum matrix composites are, low density, low thermal coefficient of performance and low weight and high strength. Among the various series of aluminum alloy, Al6061 have been widely used by researchers due to its outstanding properties particularly as they are heat treatable. Aluminum 6061 alloys have been reinforced with various particulate reinfor [...]

7Li Diffusion in Thin Disks of Single-Crystal Garnet LLZO-Ta Studied by PFG-NMR Spectroscopy

Received: 24 January 2023;  Published: 03 April 2023;  doi: 10.21926/rpm.2302014


Pulsed field-gradient (PFG) NMR spectroscopy was applied to thin disk samples (0.5, 1 and 2 mm thick, 4 mm diameter) of LLZO-Ta (Li6La3Zr1.5Ta0.5O12) single crystal. We have measured the diffusion of 7Li in thin pellets (0.5 to 3 mm thick) of NASICON-type LAGP powder and found that the Li+ diffuses preferentially in the thicker direction [...]
