Superhydrophilicity 1970-01-01
Superhydrophilicity refers to the extreme affinity of a surface to water, resulting in a very high contact angle hysteresis and the ability to attract and spread water droplets over the surface. In practical terms, materials exhibiting superhydrophilicity have low contact angles (typically less than 10 degrees), meaning that water droplets spread out almost completely on the surface rather than forming beads.
Surface-tension values 1970-01-01
Surface tension is a physical property of liquids that describes the elastic tendency of a fluid surface. It is the result of the cohesive forces between liquid molecules at the surface, which causes them to contract and minimizes the surface area. Surface tension is typically measured in units of force per unit length, often expressed in dynes per centimeter (dyn/cm) or newtons per meter (N/m). The values of surface tension can vary widely among different liquids.

Thermal desorption spectroscopy 1970-01-01
Thermal desorption spectroscopy (TDS) is an analytical technique used to study the physical and chemical properties of materials, particularly surfaces and thin films. It involves the controlled heating of a sample to release adsorbed species, such as gases or volatile compounds, and measuring their desorption as a function of temperature. In TDS, the sample is typically placed in a vacuum chamber or a controlled atmosphere.
Planka.nu 1970-01-01
Planka.nu is a website and platform that originated in Sweden, primarily focused on advocating for free public transportation as a means of promoting accessibility and sustainability. The platform is part of a broader movement that challenges traditional transportation payment models and aims to create a more equitable public transport system. The site often features information, resources, and discussions related to the issue of public transport funding, accessibility, and alternatives to fare-based systems. Activists and supporters of Planka.
Electric cars 1970-01-01
Electric cars, or electric vehicles (EVs), are vehicles that are powered entirely or partially by electricity, as opposed to conventional vehicles that rely on internal combustion engines running on gasoline or diesel fuel. Here are some key features and components of electric cars: 1. **Power Source**: Electric cars use one or more electric motors for propulsion. They are powered by rechargeable batteries that store electrical energy.
Human-powered transport 1970-01-01
Human-powered transport refers to modes of transportation that rely on human physical effort to operate, rather than engines or motors. Common examples include: 1. **Bicycles**: One of the most popular forms of human-powered transport, bicycles use pedaling to propel the rider. 2. **Walking**: The most basic form of human-powered transport, used for short distances. 3. **Running**: Similar to walking but at a faster pace, often used for recreational activities or short commutes.
Hydrogen cars 1970-01-01
Hydrogen cars, also known as hydrogen fuel cell vehicles (FCVs), are automobiles that use hydrogen as a fuel source to power an electric motor. Instead of relying on conventional fuels like gasoline or diesel, these vehicles generate electricity through a chemical reaction between hydrogen and oxygen in a fuel cell. ### Key Features of Hydrogen Cars: 1. **Fuel Cell Technology**: At the heart of a hydrogen car is the fuel cell, which converts hydrogen gas from the tank into electricity.

Common examples of personal transporters include: 1. **Electric scooters**: These are two-wheeled vehicles powered by electric motors, allowing users to easily navigate urban environments. 2. **Segways and hoverboards**: Segways use a self-balancing mechanism, whereas hoverboards are platform-style devices that also operate through balancing techniques.
Road congestion charge schemes 1970-01-01
Road congestion charge schemes are urban transportation management strategies designed to reduce traffic congestion in busy areas by imposing a fee on vehicles entering certain zones during peak hours. The primary goals of these schemes are to improve traffic flow, decrease air pollution, enhance public transport usage, and encourage the use of alternative modes of transportation, such as walking, cycling, or carpooling. ### Key Features of Road Congestion Charge Schemes: 1. **Charges**: Drivers must pay a fee when entering designated congestion zones.
