Food-Grade Nanoemulsions
Nanoemulsions, exhibiting droplet sizes of <200 nm, represent liquid-in-liquid dispersions that are kinetically stable. Water and oil are the two incompatible liquids most extensively applied in commercial environments. Because of their small size, characteristics such as visible transparency, high surface area per unit volume, sound stability and tunable rheology are often observed. Additionally, large-scale nanoemulsions’ preparation is easily achievable in industrial conditions. Therefore, nanoemulsions are especially suitable for commercial applications.

Rice Industry Value Chain and by-products valorization
The quantity of organic waste generated by agricultural sectors is continually increasing due to population growth and rising food demand. Rice is the primary consumable food in Asia. However, many stakeholders follow a linear economic model such as the “take–make–waste” concept. This linear model leads to a substantial environmental burden and the destruction of valuable resources without gaining their actual value. Because these by-products can be converted into energy generating and storage materials, and into bio-based products by cascading transformation processes within the circular economy concept, waste should be considered a central material.

Autonomous Underwater Vehicles
Development of Autonomous Underwater Vehicles (AUV's) has permitted the automatization of many tasks originally achieved with manned vehicles in underwater environments. Teams of AUV's designed to work within a common mission are opening the possibilities for new and more complex applications. In underwater environments, communication, localization, and navigation of AUV's are considered challenges due to the impossibility of relying on radio communications and global positioning systems. For a long time, acoustic systems have been the main approach for solving these challenges. However, they present their own shortcomings, which are more relevant for AUV's teams. As a result, researchers have explored different alternatives. To summarize and analyze these alternatives, a review of the literature is presented in this paper. Finally, a summary of collaborative AUV's teams and missions is also included, with the aim of analyzing their applicability, advantages, and limitations.

Ocular Medication Routes of Administration
Ocular drug administration encompasses a range of routes, each with its own advantages and limitations. The available methods include systemic delivery (such as oral, intravenous, and subcutaneous routes) as well as local delivery options (including topical eye drops, periocular or intravitreal injections, and intravitreal implants). While these approaches can be effective in delivering medications to the eye, they also have inherent drawbacks, which will be explored in greater detail in this entry. Notably, understanding the strengths and limitations of these ocular drug administration routes is crucial for optimizing therapy and achieving the desired therapeutic outcomes while minimizing potential adverse effects.

Productivity Improving Technologies
The productivity improving technologies are the technological innovations that have historically increased productivity. Productivity is often measured as the ratio of (aggregate) output to (aggregate) input in the production of goods and services. Productivity is increased by lowering the amount of labor, capital, energy or materials that go into producing any given amount of economic goods and services. Increases in productivity are largely responsible for the increase in per capita living standards.

Education on Renewable Energy in Secondary Schools
Education is key to advancing a society that can achieve the Sustainable Development Goals (SDGs). One SDG is shifting energy consumption from fossil fuels to renewable energy (RE) sources to reduce environmental damage and prevent global warming. Awareness must be instilled among citizens at an early age (as early as secondary school) to motivate students to pursue higher education and careers in RE concepts and technologies.

Unbiased Expectation Theory
Unbiased expectation theory (UET), which posits that long-term interest rates are determined by the market’s expectations of future short-term interest rates, is a fundamental concept in the field of fixed-income securities. According to the expectation hypothesis, forward interest rates should be unbiased estimates of expected future spot interest rates.

CYP2E1
CYP2E1 is one of the fifty-seven cytochrome P450 genes in the human genome and is highly conserved. CYP2E1 is a unique P450 enzyme because its heme iron is constitutively in the high spin state, allowing direct reduction of, e.g., dioxygen, causing the formation of a variety of reactive oxygen species and reduction of xenobiotics to toxic products.

The Samcheong Hanok
In Bukchon, the most representative hanok village in Seoul, there is a unique hanok, or traditional Korean house, which also looks modern. Originally built around 1940, the house underwent several stages of extension and repairs, and in 2000, was renovated by architect Wook Choi (born 1963) who called it “Samcheong Hanok” (or Samchung Hanok). Arguably, the evolution of the Samcheong Hanok illustrates a typical history of modern hanok in the past century. In the history, sudden increases in the number of hanok buildings were detected around two specific periods: first, approximately in the three decades from the early 1930s; second, in the past two decades from 2000. This phenomenon leads to classification of the hanok as urban-type or contemporary, according to whether they were built in the first or second period, respectively.
