An organic compound refinement method for refining a specific organic compound which is a target compound from at least two types of organic compounds. The method includes separating the target compound from an organic compound other than the target compound while the at least two types of organic compounds are irradiated with light at an infrared absorption wavelength of a specific functional group that is not contained in the target compound but is contained in the organic compound other than the target compound, or separating the target compound from an organic compound other than the target compound while the at least two types of organic compounds are irradiated with light at an infrared absorption wavelength of a specific functional group that is contained in the target compound but is not contained in the organic compound other than the target compound.

An electrostatic levitation crystal growth apparatus for a solution and a crystal growing method using the same. The apparatus may include an upper electrode, a lower electrode vertically spaced apart from the upper electrode, a power supply unit configured to apply a vertical electrostatic field between the upper electrode and the lower electrode, and a droplet dispenser configured to eject a solution into a region between the upper and lower electrodes and thereby to form a solution droplet. The solution droplet may be maintained in a charged state and may be electrostatically levitated against the gravity exerted thereon, by the vertical electrostatic field. The solution droplet may be evaporated in the electrostatically levitated state, and a solute dissolved in the solution may be grown to form a crystal.

The present disclosure discloses a sub-boiling distillation equipment capable of efficiently purifying a raw acid. The sub-boiling distillation equipment is made up of a feeding part, a condensing part, a heating part, a pure acid guiding part, a pure acid receiving part and a tail acid collecting part. The tail acid part is always kept in a normal temperature state, thereby ensuring that tail acid are not simultaneously heated and ensuring purity of distillates. Meanwhile, a controllable PID heating manner is adopted, so as to ensure accuracy of a heating temperature 0.1 C.

The present invention is related to a solar driven irrigation apparatus for converting contaminated water contained in a contaminated water body into distilled water and using said distilled water for irrigating the vegetation grown on the said irrigation apparatus, the solar driven irrigation apparatus comprising a cover in the form of a geometrical projection comprising a wall, an opening, a semi-permeable mesh, a soil layer and a chamber. The present invention also related to a process for irrigating natural vegetation using the solar driven irrigation apparatus.

A system for collecting solar energy and generating fresh water. The system may include a solar energy collection sub-system, a salt water distillation sub-system, and a cooling sub-system. The solar energy collection sub-system may further include one or more solar energy collection assemblies, which may heat a thermally-conductive fluid, which may be used to generate electricity. The salt water distillation sub-system may include a pump, piping, and a distillation cavity. A natural filtration and living flora/fauna sub-system may also be included.

Devices and methods are disclosed for enhancing drying, dehumidifying, cooling, dehydrating, and evaporating processes by harnessing direct, non-thermal photon-induced removal of liquid molecules from a surface. Each apparatus integrates a configurable photon-emitting module (LED, laser, or array) that delivers predominantly TM-polarized light in the visible band (e.g., 495 nm-570 nm) at an incidence configured to approximate the Brewster angle, such as within 5 of the Brewster angle. Placement of these light sources, together with light-permeable or patterned surfaces, maximizes the normal electric-field component at the interface and enlarges the illuminated area, thereby enhancing cluster ejection and vapor formation while minimizing bulk heating. Representative embodiments include a regenerating desiccator, clothes dryer, solvent extractor, indirect and direct evaporative coolers, food dehydrator, and a valveless microfluidic pump. Integrated control units modulate wavelength, pulse width, incidence geometry, airflow, and ancillary actuators in real time to match load and environmental conditions.
