"Photovoltaics" Natural Recordings by Native Speakers
Photovoltaics (PV) refers to the conversion of light into electricity through the use of semiconducting materials, primarily silicon, in a process known as photovoltaic effect. This conversion occurs when photons from the sun hit the surface of the PV cells and generate a flow of electrical current.
The new development will have photovoltaics integrated into the roof to generate electricity. The researcher at the university is studying the effects of different photovoltaics installations on energy efficiency. Solar panels are a popular type of photovoltaics used for residential power generation. The new renewable energy plan includes a large investment in photovoltaics to reduce carbon emissions. The company uses photovoltaics to power their equipment in remote locations.
Phototropin is a type of photoreceptor protein found in plants, responsible for detecting blue light and controlling plant growth and development. It plays a key role in phototropism, the phenomenon of plants growing towards or away from light sources. Phototropin is particularly important for regulating plant responses to light, such as cell elongation, cell division, and chloroplast movement, which help plants position themselves optimally to maximize their exposure to light.
Phototypes refers to the art or process of preparing photographs for reproduction or printing. It can also be used to describe photographs printed using a phototype compositor, an early digital printing device from the 1960s and 1970s that combined several photographic images into a single piece of text.
Ectopic (adj.): Relating to or situated outside the normal or proper position; occurring or situated in an abnormal place, especially in an organ or tissue.
The term "photovoltage" refers to the electromotive force (voltage) generated in a material due to the absorption of light. It is the potential difference that is created between two points in an electric field as a result of a photoelectrical effect, such as the photoelectric effect, where light hitting a material induces the ejection of electrons from its surface. The photovoltage can be used to drive an electric current in a circuit and is an essential concept in the field of photovoltaics, particularly in the study and development of solar cells and photovoltaic devices.
Photoxylography is a reproduction technique that combines photostatic and xylographic processes to create images.
Photronic refers to something that is related to or controlled by light, particularly in reference to photography or optics. However, in a more specific context, the term was historically used to describe hypothetical environmental energy, known as the "zones of the photronic field" in an overly hypothetical/ debunked homeopathy-related concept.In a more scientifically-grounded sense, it may also connote technologies or concepts that exploit photonics or photonic principles to control light or to power devices, but it's not widely used in mainstream scientific or technical contexts anymore.
PHP stands for "Hypertext Preprocessor". It is a server-side scripting language used primarily for web development.
Phragmites is a type of common reed or tall grass that is native to Europe, Asia, and Africa, but has been naturalized in many other parts of the world. It grows in wetlands, riverbanks, and coastal areas, and can grow up to 12 feet tall. The culms are thick and woody, with flat and pointed leaves and a prominent node at the base of each leaf.The plant has been used for various purposes, including erosion control, reclamation of wetlands, and as a food source for livestock. However, phragmites can also be an invasive species in certain ecosystems, crowding out native plants and altering the environment.
A phragmocone is a chambered internal shell piece of an extinct type of cephalopod known as an ammonite.
The phragmoplast is a structure formed during the mitosis of plant cells, particularly during the formation of a cell plate during the telophase stage. It is a microtubule-based scaffold that eventually leads to the formation of a cross-wall or cell plate, effectively dividing the parent cell into two daughter cells.The phragmoplast is formed after the chromosomes have been separated, and it serves several important functions:1. <strong>Cell Plate Formation</strong>: The phragmoplast guides the movement and assembly of vesicles containing cell wall components, such as cellulose, hemicellulose, and pectin. These components are involved in the synthesis of the new cell plate that will eventually separate the two daughter cells.2. <strong>Cell Wall Synthesis</strong>: The phragmoplast template dictates the arrangement of microfibrils and glycoproteins in the burgeoning wall. The coordinated synthesis of cellulose, hemicellulose, and pectin ensures the proper elasticity, integrity, and growth characteristics of the new cell wall.3. <strong>Cell Plate Expansion</strong>: As the phragmoplast extends further, it expands in a specific manner to produce the new cell plate, ensuring proper cell division. At the center of the sedges, it also forms the primary spiral structures involved in the growing highlights.4. <strong>Division Completion</strong>: Finally, upon completion, this determines the final completed completion of the plant cell upon differentiation.
A phrasal verb refers to a type of verb that is composed of a main verb and one or more additional particles (prepositions or adverbs) that together form a new verb with a meaning different from that of the individual words on their own. For example:<em> "pick up" (to lift something)</em> "call off" (to cancel a plan) "turn on" (to switch something to an active state)In each of these cases, the prepositions "up", "off", and "on" modify the meaning of the main verb "pick", "call", and "turn", respectively, to create a new meaning.
A phrasal verb is a verb that is combined with a preposition or an adverb to form a new verb with a different meaning. Each phrasal verb is comprised of two or three words which can be:<em> A verb and a preposition (e.g., "pick up")</em> A verb and an adverb (e.g., "go on") A verb, a preposition, and an adverb (e.g., "come across")Phrasal verbs can be separable, inseparable, or of two types.
