This study offers an overview of the technologies for hydrogen production especially alkaline water electrolysis using solar energy. Solar Energy and Hydrogen (energy carrier) are possible replacement options for fossil fuel and its associated problems of availability and high prices which are devastating small, developing, oil-importing economies. But a major drawback to the full implementation of solar energy, in particular photovoltaic (PV), is the lowering of conversion efficiency of PV cells due to elevated cell temperatures while in operation. Also, hydrogen as an energy carrier must be produced in gaseous or liquid form before it can be used as fuel; but its‟ present major conversion process produces an abundance of carbon dioxide which is harming the environment through global warming. Alkaline water electrolysis is considered to be a basic technique for hydrogen production. In the present study, the effects of electrolyte concentration, solar insolation and space between the pair of electrodes on the amount of hydrogen produced and consequently on the overall electrolysis efficiency are experimentally investigated. The water electrolysis of potassium hydroxide aqueous solution was conducted under atmospheric pressure using stainless steel 316 as electrodes.
The experimental results showed that the performance of alkaline water electrolysis unit is dominated by operational parameters like the electrolyte concentration and the gap between the electrodes. Smaller gaps between the pair of electrodes and was demonstrated to produce higher rates of hydrogen at higher system efficiency
This study shows some attempts to product pure Hydrogen and pure Oxygen as both Hydrogen and Oxygen have there commercial demands.

Identifying Challenges and Solutions in Electric Ladle PreheatingLeonardo ENERGY
Foundries use ladles to transfer molten metal from the melt operation to cast operation. Currently, gas and oil firing are the most common method of drying and heating of refractory lined ladles, tundishes, soaking pits and various furnaces in steel mills and other small and big foundries. Convective heating for heating the refractory linings can be achieved by using dedicated burner setups for ladles and tundishes. However, this method has very low efficiency, in the order of 5-25%. Alternatively, electric ladle pre-heating offers many advantages over the current methods. In this webcast, the current practices used in foundries for pre-heating ladles, some of the disadvantages of the current practices, and few potential solutions to improve efficiency of this process will be covered.

Carbon nanofibers (CNF) supported Pd–Ni nanoparticles have been prepared by chemical reduction
with NaBH4 as a reducing agent. The Pd–Ni/CNF catalysts were characterized by X-ray diffraction
(XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electrochemical
voltammetry analysis. TEM showed that the Pd–Ni particles were quite uniformly distributed on the
surface of the carbon nanofiber with an average particle size of 4.0 nm. The electro-catalytic activity of
the Pd–Ni/CNF for oxidation of ethanol was examined by cyclic voltammetry (CV). The onset potential
was 200mV lower and the peak current density four times higher for ethanol oxidation for Pd–Ni/CNF
compared to that for Pd/C. The effect of an increase in temperature from 20 to 60 ◦C had a great effect on
increasing the ethanol oxidation activity

As part of the series of regional engagements in South Asia, Smart Villages is organising a workshop on off-grid rural energy provision in Bangladesh. The country has the fastest growing programme in the world with an estimated 70,000 solar home systems (SHS) installed per day. More than 3 million SHS have been installed in off-grid rural areas in the country bringing electricity to an estimated 13 million people.
The aim of the workshop is to gain insights from the experience of a wide variety of stakeholders in Bangladesh who are involved in rural off-grid energy provision in the country. This workshop will offer a number of potential lessons to other countries within the region. The workshop provides an opportunity to gain a deeper understanding of the opportunities presented by expansion of solar home systems (SHS) and mini-grids to off-grid rural communities and the challenges faced in this expansion. During this workshop we will also investigate the potential impact of energy access on rural livelihoods in the country.
The workshop is being jointly organised by Smart Villages and Practical Action.
Asymmetric Multipole Plasmon-Mediated Catalysis Shifts the Product Selectivit...Pawan Kumar
Cu/TiO2 is a well-known photocatalyst for the photocatalytic transformation of CO2 into methane. The formation of C2+ products such as ethane and ethanol rather than methane is more interesting due to their higher energy density and economic value, but the formation of C–C bonds is currently a major challenge in CO2 photoreduction. In this context, we report the dominant formation of a C2 product, namely, ethane, from the gas-phase photoreduction of CO2 using TiO2 nanotube arrays (TNTAs) decorated with large-sized (80–200 nm) Ag and Cu nanoparticles without the use of a sacrificial agent or hole scavenger. Isotope-labeled mass spectrometry was used to verify the origin and identity of the reaction products. Under 2 h AM1.5G 1-sun illumination, the total rate of hydrocarbon production (methane + ethane) was highest for AgCu-TNTA with a total CxH2x+2 rate of 23.88 μmol g–1 h–1. Under identical conditions, the CxH2x+2 production rates for Ag-TNTA and Cu-TNTA were 6.54 and 1.39 μmol g–1 h–1, respectively. The ethane selectivity was the highest for AgCu-TNTA with 60.7%, while the ethane selectivity was found to be 15.9 and 10% for the Ag-TNTA and Cu-TNTA, respectively. Adjacent adsorption sites in our photocatalyst develop an asymmetric charge distribution due to quadrupole resonances in large metal nanoparticles and multipole resonances in Ag–Cu heterodimers. Such an asymmetric charge distribution decreases adsorbate–adsorbate repulsion and facilitates C–C coupling of reaction intermediates, which otherwise occurs poorly in TNTAs decorated with small metal nanoparticles.

Electro-oxidation And Its Feasibility In Wastewater TreatmentSakib Shahriar
Electro-oxidation (EO) is one of the advanced oxidation processes (AOP) used in wastewater treatment. It is also called anodic oxidation. In this presentation, we can learn about the working principle, industrial applications, types of electrodes, and catalysts in the EO process. The advantages and disadvantages are described later. The main advantages of electro-oxidation are the formation of low sludge and large percentages of organic matter degradation. But the main drawbacks occur due to the requirement of large space and expense. EO is used in many types of wastewater treatment. Degradation of methyl orange azo dye in a recirculation flow plant system, treatment of wastewater containing aromatic amines, endocrine disruptors treatment, domestic water, industrial wastewater, synthetic dye effluent, olive mill wastewater, pulp mill wastewater, citric acid wastewater.

In a May 9, 2024 paper, Juri Opitz from the University of Zurich, along with Shira Wein and Nathan Schneider form Georgetown University, discussed the importance of linguistic expertise in natural language processing (NLP) in an era dominated by large language models (LLMs).
The authors explained that while machine translation (MT) previously relied heavily on linguists, the landscape has shifted. “Linguistics is no longer front and center in the way we build NLP systems,” they said. With the emergence of LLMs, which can generate fluent text without the need for specialized modules to handle grammar or semantic coherence, the need for linguistic expertise in NLP is being questioned.
