Resumen

Solar-driven interfacial water evaporation (SWE) is considered as a promising sustainable solution for clean water production especially for remote and off-grid communities. Various approaches have been developed in the last decade to improve the evaporation and thermal efficiency of the system, and to make it more robust for long-term operation. In recent years, 3D printing has emerged as an attractive method to fabricate simple and complex absorber geometries for SWE. In this mini-review, we present the new developments of 3D-printed solar absorbers including the various designs, fabrication

Resumen

A machine in action in a plant mine or other mechanical system is a major source of vibrations that spread from foundation and across the surrounding area. There should be the least amount of vibrations possible. The vibrations must be isolated, absorbed, or dampened in order to do this. This study investigates how an oil damper and various types of vibration isolators affect vibration frequency of a stir cast composite beam made up of 90% Al6061 and 10% SiC to examine the influence of an oil damper well, as single and double absorbers on the vibration frequency of a stir cast composite beam.

Resumen

ABSTRACT Some fraction of narrow absorption lines (NALs) are physically associated to the quasar/host-galaxy materials (i.e. intrinsic NALs) like those of broad absorption lines (BALs) and mini-BALs. The relation between these three types of absorption lines has not been understood yet, however one interpretation is that these absorption features correspond to different inclination angles. In this study, we search for intrinsic NALs in 11 BAL/mini-BAL quasar spectra retrieved from VLT/UVES public archive, in order to test a possible relation of intrinsic NALs and BALs/mini-BALs in the geometry

Resumen

In the photoelectrochemical (PEC) water splitting (WS) reactions, a photon is absorbed by a semiconductor, generating electron-hole pairs which are transferred across the semiconductor/electrolyte interface to reduce or oxidize water into oxygen or hydrogen. Catalytic junctions are commonly combined with semiconductor absorbers, providing electrochemically active sites for charge transfer across the interface and increasing the surface band bending to improve the PEC performance.

Resumen

With the growing demand for photovoltaic (PV) systems as a source of energy generation that produces no greenhouse gas emissions, effective strategies are needed to address the inherent inefficiencies of PV systems. These systems typically absorb only approximately 15% of solar energy and experience performance degradation due to temperature increases during operation. To address these issues, PV–thermal (PVT) technology, which combines PV with a thermal absorber to dissipate excess heat and convert it into additional thermal energy, is being rapidly developed.

Abstract Objective: To test the hypothesis that there is no difference in the stability and resistance to rotational moments of early loaded sandblasted and acid-etched (SLA) mini-implants and those of machined-surface implants of the same size and shape. Materials and Methods: A randomized complete block design was used in 12 skeletally mature male beagle dogs. Ninety-six orthodontic mini-implants were tested. Two types of implants were used: some had SLA surface treatment and some had machined surfaces without coating. After 3 weeks of healing, rotational moments of 150 g were applied. The s

Resumen

Oxygen-free high-conductivity copper (OFHC), chromium-zirconium copper (CuCrZr), and Glidcop® AL-15 are widely used in the high heat load absorber elements at the front end of synchrotron radiation facilities. It is necessary to choose the most suitable material according to the actual engineering conditions (such as the specific heat load, material performance, and costs). In the long-term service period, the absorber elements have to bear hundreds or kilowatts of high heat load and its “load-unload” cyclic loading mode. Therefore, the thermal fatigue and thermal creep properties of the mater

Resumen

This paper pursues a phenomenological investigation of the nature of absorbed listening in Western, classical music concert audiences. This investigation is based on a data-set of 16 in-depth phenomenological interviews with audience members from three classical concerts with the Stavanger Symphony Orchestra and the Norwegian Radio Orchestra conducted in spring 2024. We identify seven major themes, namely “sharedness”, “attention”, “spontaneous thought/mental imagery”, “modes of listening” “absorption”, “distraction”, and “strong emotional experiences”, and interpret these in light of relevant

Abstract: In a country like India, two-wheeler vehicles are predominant over four wheelers. According to data taken from internet, around 20 million two wheelers were sold in 2017/18, as compared to 4 million four wheelers. And this demand keeps on increasing in India. Keeping this mind, a huge potential of energy is being wasted every day. This project is one of the methods to harvest those wasted energy. That’s why this project is under energy recovery. All the major advancements and break through has been done mostly on four wheelers. To name some energy recovery mechanisms, regenerative br

Abstract The aim of the present study was to investigate the effect of absorbent level and microbial inoculant on chemical compositions and fermentation characteristics of fermented poultry manure (FPM). In the first trial, the FPM was fermented using two levels of cassava solid waste as absorbent, consisted of 10% (AL10) and 30% (AL30). The best absorbent level to improve the quality of FPM was continued in the second trial. In the second trial, FPM was fermented using inoculant treatments following without inoculants (CON), Lactobacillus plantarum (LP) and multi-purpose microbes (MP). All fe

Resumen

Room surfaces have been extensively modeled as locally reacting in room acoustic predictions although such modeling could yield significant errors under certain conditions. Therefore, this study aims to propose a guideline for adopting the local reaction assumption by comparing predicted random incidence acoustical characteristics of typical building elements made of porous materials assuming extended and local reaction. For each surface reaction, five well-established wave propagation models, the Delany-Bazley, Miki, Beranek, Allard-Champoux, and Biot model, are employed. Effects of the flow

AbstractIn recent years, sub-wavelength metamaterials-based light perfect absorbers have been the subject of many studies. The most frequently utilized absorber configuration is based on nanostructured plasmonic metals. However, two main drawbacks were raised for this design architecture. One is the fabrication complexity and large scale incompatibility of these nano units. The other one is the inherent limitation of these common metals which mostly operate in the visible frequency range. Recently, strong interference effects in lithography-free planar multilayer designs have been proposed as

Transitional pulsars provide us with a unique laboratory to study the physics of accretion onto a magnetic neutron star. PSR J1023+0038 (J1023) is the best studied of this class. We investigate the X-ray spectral properties of J1023 in the framework of a working radio pulsar during the active state. We modelled the X-ray spectra in three modes (low, high, and flare) as well as in quiescence, to constrain the emission mechanism and source parameters. The emission model, formed by an assumed pulsar emission (thermal and magnetospheric) plus a shock component, can account for the data only adding

Abstract A Cosmic Muon Veto (CMV) detector using extruded plastic scintillators is being designed around the mini-Iron Calorimeter (mini-ICAL) detector at the transit campus of the India based Neutrino Observatory, Madurai for the feasibility study of shallow depth underground experiments. The scintillation signals that are produced in the plastic due to muon trajectories are absorbed by wavelength shifting (WLS) fibres. The WLS fibres re-emit photons of longer wavelengths and propagate those to silicon photo-multipliers (SiPMs). The SiPMs detect these photons, producing electronic signals. Th
