With desirable physical performances of impressive actuation strain, high energy density, high degree of electromechanical coupling and high mechanical compliance, dielectric elastomer actuators (DEAs) are widely employed to actuate the soft robots. However, there are many challenges to establish the dynamic models fo…
An anapole state that breaks inversion and time reversal symmetries with preserving translation symmetry of underlying lattice has aroused great interest as a new quantum state, but only a few candidate materials have been reported. Recently, in a spin-orbit coupled Mott insulator \SIR, the emergence of a possible hid…
In the present work, nanocomposites based on the partially silane-terminated polyurethanes reinforced with sulfuric acid-treated halloysite nanotubes were synthesized and evaluated as a potential candidate for transparent blast resistant configurations. The polyurethane must present high tensile ductility at high stra…
We have demonstrated that exposing human breast tumour xenografts to ultrasound-stimulated microbubbles enhances tumour cell death and vascular disruption resulting from hyperthermia treatment. The aim of this study was to investigate the effect of varying the hyperthermia and ultrasound-stimulated microbubbles treatm…
Abstract A quantitative study on the kinetics of nucleation of primary Si particles (PSPs), especially under the effect of P inoculation, during isothermal melt solidification of hypereutectic Al–Si(–Cu) alloys has been realized for the first time by using a unique micro-focus in situ X-radiography method, which is im…
Among the next-generation photovoltaics (PVs), hybrid organic–inorganic perovskite solar cells (PeSCs) have drawn tremendous attention from both academic and industrial communities, because of their compelling combination of high performance, high cost-effectiveness, and broader feasibility. Despite the rapid growth a…
Novel birch bark dry extract (TE)-loaded polyvinyl alcohol (PVA) fiber mats intended for wound therapy were developed through an electrospinning process. Colloidal dispersions containing TE as the active substance were prepared by the high-pressure homogenization (HPH) technique using hydrogenated phospholipids as sta…
Abstract An extensive analysis of the fatigue life of a typical modern autofrettaged smoothbore tank barrel, cracked either internally or externally, in terms of the initial crack depth and shape, type and level of autofrettage, was conducted. Five overstraining cases were considered: no-autofrettage, 70% and 100% hyd…
Penelitian ini dimaksudkan untuk mengetahui karakteristik penggunaan agregat Sungai Batu Tiakka’ dalam Campuran AC-BC. Metode dalam penelitian ini adalah melakukan serangkaian pengujian karakteristik agregat kasar, halus, dan filler kemudian merancang komposisi campuran AC-BC serta pengujian Marshall untuk mendapatkan…
The objective of this study is to elucidate the mechanism by which blockages occur in sewer pipes following the deposition of fat, oil, and grease (FOG) and suspended solids (SS). In this study, a simulated wastewater flow experiment was conducted to elucidate the mechanism of sewer pipe blockage using lauric acid as…
Abstract Molten carbonate fuel cells (MCFCs) offer several advantages that are attracting an increasingly intense research and development effort. Recent advances include improved materials and fabrication techniques as well as new designs, flow configurations, and applications. Several factors are holding back large-…
One of the most current trends in applied electrochemistry is the development of solid ionic conductors with electrical, mechanical and optical properties tailored for a specific functional application. Moreover, particular interest exists in materials with low environmental impact and low cost where matters as sustai…

Metodologi dalam penelitian ini adalah melakukan serangkaian pengujian karakteristik berupa agregat kasar,…
AlGaN-based germicidal UV LEDs show promise in fighting the COVID-19 pandemic through disinfection of air, water, and surfaces. We report UV LEDs grown by MOCVD on SiC substrates, fabricated into thin-film flip chip devices. Replacing the uniform p-Al x Ga1-xN layer (x = 0.2) with a short-period-superlattice of altern…
This paper mainly focuses on increasing the conversion efficiency of GaAs solar cells by reducing the light reflection losses. The design of nano-structured gratings and their light trapping performance are modelled and optimised by using the finite-difference time-domain (FDTD) method. The sunlight directly impinges…
Nonwoven fibrous materials are a unique class of porous materials that are widely used for filtration and separation applications. The complex pore structure in fibrous media, with high connectivity and low tortuosity, enhances filtration efficiency while preventing filter fouling. The pore size distribution is a key…
Abstract Full-inorganic CsPbIBr2 optoelectronic devices have received huge attention in energy technology owing to their prime photovoltaic properties and promising thermal stability. However, CsPbIBr2 perovskite films obtained by conventional spin coating always have bad morphology, poor crystallinity, and thin thick…
Abstract In this study the first viscosity measurements in the glass transition range of melts from highly explosive large-volume eruptions from the Colli Albani Volcanic District (CAVD) are presented. The magmas are ultrapotassic, rich in iron and CaO and characterised by a low silica content (< 45 wt%). Melt composi…
YoeB-YefM, the widespread type II toxin-antitoxin (TA) module, binds to its own promoter to autoregulate its transcription: repress or induce transcription under normal or stress conditions, respectively. It remains unclear how YoeB-YefM regulates its transcription depending on the YoeB to YefM TA ratio. We find that…
Controlling the system-the environment of power plants is called such a transformation-their material, energy and information inputs in time, which will ensure that the purpose of the operation of this system or the state of the environment, is achieved. The transformations of systems and environmental inputs and thei…
