Question: Thyristor power controllers (SCR power controllers) control power or voltage supplied to a load, the controllers are used in industrial furnace construction or in the processing of which material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects?

Context paragraphs:
CPU core voltage: The CPU core voltage (V) is the power supply voltage supplied to the CPU (which is a digital circuit), GPU, or other device containing a processing core.  The amount of power a CPU uses, and thus the amount of heat it dissipates, is the product of this voltage and the current it draws.

Electric power quality: Electric power quality, or simply power quality, involves voltage, frequency, and waveform.  Good power quality can be defined as a steady supply voltage that stays within the prescribed range, steady a.c. frequency close to the rated value, and smooth voltage curve waveform (resembles a sine wave).  In general, it is useful to consider power quality as the compatibility between what comes out of an electric outlet and the load that is plugged into it.  The term is used to describe electric power that drives an electrical load and the load's ability to function properly.  Without the proper power, an electrical device (or load) may malfunction, fail prematurely or not operate at all.  There are many ways in which electric power can be of poor quality and many more causes of such poor quality power.

Voltage regulation: In electrical engineering, particularly power engineering, voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component, such as a transmission or distribution line.  Voltage regulation describes the ability of a system to provide near constant voltage over a wide range of load conditions.  The term may refer to a passive property that results in more or less voltage drop under various load conditions, or to the active intervention with devices for the specific purpose of adjusting voltage.

Carbon fixation: Carbon fixation or сarbon assimilation is the conversion process of inorganic carbon (carbon dioxide) to organic compounds by living organisms.  The most prominent example is photosynthesis, although chemosynthesis is another form of carbon fixation that can take place in the absence of sunlight.  Organisms that grow by fixing carbon are called autotrophs. Autotrophs include photoautotrophs, which synthesize organic compounds using the energy of sunlight, and lithoautotrophs, which synthesize organic compounds using the energy of inorganic oxidation.  Heterotrophs are organisms that grow using the carbon fixed by autotrophs.  The organic compounds are used by heterotrophs to produce energy and to build body structures.  "Fixed carbon", "reduced carbon", and "organic carbon" are equivalent terms for various organic compounds.

Benistor: A benistor is a controllable electron valve capable to independently manage the amount of voltage and current between generator and load in an electrical circuit.  The benistor is able to modulate the value of any or all of following parameters delivered to a load: maximum voltage, effective voltage, average voltage, maximum current, effective current, or average current.  The benistor achieves this modulation by means of several voltage and current control terminals.  The benistor’s capability to operate in linear, switching, or self-switching mode of operation, controlling the voltage amount on the vertical axis and the current amount on the horizontal axis (see oscilloscope waveforms), makes it an extremely versatile control device for power management applications, especially for circuits involving non-linear loads, such as LED (Light Emitting Diode) power converters (drivers).

Bang–bang control: In control theory, a bang–bang controller (2 step or on–off controller), also known as a hysteresis controller, is a feedback controller that switches abruptly between two states.  These controllers may be realized in terms of any element that provides hysteresis.  They are often used to control a plant that accepts a binary input, for example a furnace that is either completely on or completely off.  Most common residential thermostats are bang–bang controllers.  The Heaviside step function in its discrete form is an example of a bang–bang control signal.  Due to the discontinuous control signal, systems that include bang–bang controllers are variable structure systems, and bang–bang controllers are thus variable structure controllers.

Voltage controller: A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, TRIACs, SCRs or IGBTs, which converts a fixed voltage, fixed frequency alternating current (AC) electrical input supply to obtain variable voltage in output delivered to a resistive load.  This varied voltage output is used for dimming street lights, varying heating temperatures in homes or industry, speed control of fans and winding machines and many other applications, in a similar fashion to an autotransformer.  Voltage controller modules come under the purview of power electronics.  Because they are low-maintenance and very efficient, voltage controllers have largely replaced such modules as magnetic amplifiers and saturable reactors in industrial use.

Borylation: Metal-catalyzed C–H borylation reactions are transition metal catalyzed organic reactions that produce an organoboron compound through functionalization of aliphatic and aromatic C–H bonds and are therefore useful reactions for carbon–hydrogen bond activation.  Metal-catalyzed C–H borylation reactions utilize transition metals to directly convert a C–H bond into a C–B bond.  This route can be advantageous compared to traditional borylation reactions by making use of cheap and abundant hydrocarbon starting material, limiting prefunctionalized organic compounds, reducing toxic byproducts, and streamlining the synthesis of biologically important molecules.  Boronic acids, and boronic esters are common boryl groups incorporated into organic molecules through borylation reactions.  Boronic acids are trivalent boron-containing organic compounds that possess one alkyl substituent and two hydroxyl groups.  Similarly, boronic esters possess one alkyl substituent and two ester groups.  Boronic acids and esters are classified depending on the type of carbon group (R) directly bonded to boron, for example alkyl-, alkenyl-, alkynyl-, and aryl-boronic esters.  The most common type of starting materials that incorporate boronic esters into organic compounds for transition metal catalyzed borylation reactions have the general formula (RO)B-B(OR).  For example, Bis(pinacolato)diboron (BPin), and bis(catecholato)diborane (BCat) are common boron sources of this general formula.

Plastic: Plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects.

Thyristor power controller: Thyristor power controllers (SCR power controllers) control power or voltage supplied to a load.  Typical applications are generally found where power needs to be varied and ultimately converted into thermal energy.  For example, the controllers are used in industrial furnace construction or in plastic processing.
