  2. Osteocyte - Wikipedia

    en.wikipedia.org/wiki/Osteocyte

    An osteocyte, an oblate shaped type of bone cell with dendritic processes, is the most commonly found cell in mature bone. It can live as long as the organism itself. [1] The adult human body has about 42 billion of them. [2] Osteocytes do not divide and have an average half life of 25 years.

  3. Lacuna (histology) - Wikipedia

    en.wikipedia.org/wiki/Lacuna_(histology)

    In an ordinary microscopic section, viewed by transmitted light, they appear as fusiform opaque spots. Each lacuna is occupied during life by a branched cell, termed an osteocyte, bone-cell or bone-corpuscle. Lacunae are connected to one another by small canals called canaliculi. A lacuna never contains more than one osteocyte.

  4. Chondrocyte - Wikipedia

    en.wikipedia.org/wiki/Chondrocyte

    Mesenchymal (mesoderm origin) stem cells are undifferentiated, meaning they can differentiate into a variety of generative cells commonly known as osteochondrogenic (or osteogenic, chondrogenic, osteoprogenitor, etc.) cells. When referring to bone, or in this case cartilage, the originally undifferentiated mesenchymal stem cells lose their ...

  5. Bone canaliculus - Wikipedia

    en.wikipedia.org/wiki/Bone_canaliculus

    Diameter of canaliculi in human bone is approximately 200 to 900 nm. [1] In bovine tibia diameter of canaliculi was found to vary from 155 to 844 nm (average 426 nm). [ 2 ] In mice humeri it varies from 80 to 710 nm (average 259 nm), while diameter of osteocytic processes varies from 50 to 410 nm (average 104 nm).

  6. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.

  7. Timeline of solar cells - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_solar_cells

    2008 - New record achieved in solar cell efficiency. Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have set a world record in solar cell efficiency with a photovoltaic device that converts 40.8% of the light that hits it into electricity. However, it was only under the concentrated energy of 326 suns ...

    The researchers found the presence of CMV antibodies all over patients with Alzheimer's disease, including the intestines, spinal fluid, brains, and vagus nerves.

  9. Biological photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Biological_photovoltaics

    Biological photovoltaic devices are a type of biological electrochemical system, or microbial fuel cell, and are sometimes also called photo-microbial fuel cells or “living solar cells”. [3] In a biological photovoltaic system , electrons generated by photolysis of water are transferred to an anode . [ 4 ]
