Oil Lamps of Banu Musa

open access: yesآموزش مهندسی ایران, 2016
One of the most important topics in the field of engineering is automatic control of industrial systems with feedback or without it. Most of the university teachers and students think that the subject of automatic control is relatively a young branch of engineering.

The impact of the government policies and incentives to promote the export of agricultural products in Tunisia: case of olive oil [PDF]

open access: yes
The agricultural sector is very important for the Tunisian economy as it absorbs 10% of the total investment, generates 12% of the Gross Domestic Product (2002-2006) and employs 16% of the total labor force while the agro food exports represent 10% of ...

Advancing Sustainable Development Through Exports of Clean Energy Products From Emerging Asian Economies: A Poisson Pseudo Maximum Likelihood Estimation Approach

open access: yesSustainable Development, EarlyView.
ABSTRACT The promotion of clean energy is critical to achieving sustainable development. This study investigates the factors that affect the exports, trade potential, and revealed comparative advantage (RCA) of clean energy products (CEPs) in the emerging Asian economies (EAEs).

Self‐Assembled Conjugated Hollow Fibers for Spongy Monoliths Toward Solar‐Driven Desalination and Hydrovoltaic Electricity Generation

open access: yesSmall, EarlyView.
A self‐assembled conjugated hollow fiber monolith enables simultaneous solar‐driven desalination and hydrovoltaic electricity generation. Metal‐free polymerization produces cross‐linked hollow fibers that entangle into a porous monolith, followed by gradient polypyrrole coating for efficient light absorption and directional water transport.

Wafer‐Scale Deterministic Fabrication of Axis‐Ratio–Engineered Silicon Nanoparticles for On‐Resonance Electric–Magnetic Dipole Interference

open access: yesSmall, EarlyView.
Wafer‐scale top‐down fabrication yields silicon nanoparticles with exceptional uniformity (CV 1.7%–2.4%), enabling deterministic axis‐ratio tuning. At AR ≈$\approx$ 2.1, electric–magnetic dipoles overlap on‐resonance, producing near‐Kerker forward scattering (F/B ≈$\approx$ 12.5).

Energy Transfer in Nanodroplet‐Based Luminescent Solar Concentrators

open access: yesSmall, EarlyView.
We present novel luminescent solar concentrators (LSCs) featuring polymer composites with fluorescent dye‐doped oil nanodroplets. This liquid environment ensures high dye solubility and preserves fluorescence quantum yields, even at high local dye concentrations.
