Disclosed is a light-material coupling and emitting apparatus for coupling and emitting light and a material. The present disclosure is to utilize light coupled with a gaseous material or a certain state of material. According to the present disclosure, light is coupled with a gas, a liquid, or any state (plasma state) of material, and the coupled light and the material are emitted toward a target object or a predetermined region. When reaching the target object or the predetermined region, the material reacts with another material existing around the target object or the predetermined region. According to one embodiment, when light coupled with a first material is emitted from the light-material coupling and emitting apparatus, the first material coupled with the light falls away from the light and then chemically reacts with a second material. The apparatus uses a specific effect caused by this chemical reaction.

Methods of concurrently forming ammonia and solid carbon products include reacting a carbon oxide, nitrogen, and a reducing agent at preselected reaction conditions in the presence of a catalyst to form a solid carbon product entrained in a tail gas mixture comprising water and ammonia; separating entrained solid carbon product from the tail gas mixture; and recovering water and ammonia from the tail gas mixture. Systems for forming ammonia and solid carbon products from a gaseous source containing carbon oxides include mixing means for mixing the gaseous source with a reducing agent, reactor means for reacting at least a portion of the gaseous source with the reducing agent in the presence of a catalyst to produce the solid carbon products and a tail gas mixture comprising the ammonia, and solid separation means for separating the solid carbon products from the tail gas mixture.

Deuterium-depleted water is produced easily and inexpensively. A method for producing deuterium-depleted water by removing heavy water and semi-heavy water from water includes an adsorption step of supplying water vapor to a predetermined adsorbent at pressure at which heavy water and semi-heavy water are adsorbed by the adsorbent and light water is not easily adsorbed, causing the heavy water and semi-heavy water to be adsorbed, and recovering the water vapor not adsorbed by the adsorbent. The method also includes a desorption step of maintaining vapor pressure around the predetermined adsorbent which has adsorbed the water vapor in a range in which light water is desorbed and heavy water or semi-heavy water is not easily desorbed, and recovering the water vapor desorbed from the adsorbent.
