摘要： Methods and apparatus are disclosed for triggering an exothermic reaction under a high hydrogen loading rate. It is generally understood that a high hydrogen loading ratio is an important factor. The present application teaches that a high hydrogen loading rate, that is, achieving a high hydrogen loading ratio in a short period of time, is another important factor in determining whether excess heat can be observed in an exothermic reaction. The present application discloses methods and apparatus for achieving a high hydrogen loading rate in order to trigger an exothermic reaction.

摘要： A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.

摘要： Disclosed is a technique for reducing CO2 to oxalate utilizing a copper-free, nickel-enhanced electrocatalyst (such as a nickel-enhanced (Cr2O3)3(Ga2O3) electrocatalyst) that can be used for producing, e.g., 1-butanol, in exceedingly high yields. Disclosed herein are various synthetic methodologies for introducing nickel into the electrocatalysts, and described is the characterization, and optimization of the Ni enhanced electrocatalysts for the reduction of CO2 to 1-butanol with a maximum faradaic efficiency ξmax of 64%, at an overpotential of 900 mV (−1.48 V vs Ag/AgCl), and having an onset overpotential of 320 mV. The product selectivity is potential dependent with other C2+ products such as 3-hydroxybutanal, (ξmax 63%) at an overpotential of 890 mV (−1.4 V vs Ag/AgCl); acetic acid with ξmax 18% at an overpotential of 390 mV (−1.0 V vs Ag/AgCl); and acetone with ξmax 10% at an overpotential of 620 mV (−1.2 V).

摘要： Electrocatalytic overall water splitting to generate hydrogen and oxygen is a green and sustainable approach with zero carbon emission, which is important for the future renewable energy landscape. The practical application of this approach is challenging due to the sluggish reaction kinetics of water activation at high current densities, which are hard to overcome. Although high-performance alkaline bifunctional electrocatalysts may be useful, current catalysts lack both activity and durability. One approach is to rationally design bifunctional two-dimensional (2D) heterostructures but obtaining an efficient and durable catalyst has proved difficult. The present disclosure relates generally to an electrocatalyst including a 2D heterostructure (Ru-CMOP), methods of making and using the same. The catalyst of the present disclosure is designed for high activity and good durability at industrial-level high current densities.

摘要： Electrochemical systems and methods for removing and recovering phosphorus, in the form of phosphates, from aqueous solutions are provided. The removal of the phosphates takes place in an electrochemical cell having an electrode that includes bismuth (Bi), zinc (Zn), copper (Cu), iron (Fe), or an oxide thereof. During the removal of phosphates from aqueous solution, the metal (Bi, Zn, Cu, or Fe) and/or metal oxide of the electrode is converted into its corresponding metal phosphate within the electrode via a reversible conversion reaction. The phosphate stored in the electrode during the removal step is subsequently released into a recovery solution via electrochemical reduction of the metal phosphate back into a metal.
