Abstract: This application discloses a battery cabinet. A drain assembly is disposed at the bottom of a cabinet body of the battery cabinet. The drain assembly includes a drain valve. A valve spool and a magnetic object are disposed in the drain valve. The valve spool is movably disposed in the drain valve and has a first state of sealing the drain valve or a second state of opening the drain valve. The magnetic object generates a magnetic force to keep the valve spool in the first state, and the valve spool stays in the second state when a downward force applied to the valve spool is greater than a preset value. Therefore, draining is started when the water accumulated on the valve spool reaches a specified weight, and a new valve spool is automatically closed after the water is drained.

Abstract: With the fasting growth of renewable energy resources and DC supplied loads, DC electrical systems have been increasingly received attentions all over the world. DC breaker systems play a key role in protection systems for disconnecting sources and loads, and they are also used mainly for removing faulted sections from the system accurately and reliably. Solid state DC breakers benefit from fast response time and compactness features; however, due to the lack of zero current realization and high-power losses, the reliability and efficiency of these devices is low. The system proposes a solid-state DC breaker for medium voltage DC (MVDC) systems.

Abstract: Provided is a method for synthesizing 2H/1T? transition metal dichalcogenide (TMD) heterophase junctions. Synthesis of vertical 2H/1T? MoS2 heterophase junction is achieved by growing 2H MoS2 monolayers on a mica substrate under pure Ar carrier gas, and then growing 1T? MoS2 nanoribbons on top of the 2H MoS2 monolayers by changing the carrier gas from pure Ar to a mixture of Ar and H2 gases. The integrated devices based on 2H/1T? MoS2 heterophase structures display typical rectifying behavior with a current rectifying ratio of over 102 and achieve a responsivity of 1.07 A/W at 532 nm with an ultra-low dark current of lower than 10-11 A. These superior features make 2H/1T? MoS2 heterophase structure a promising candidate for future rectifiers as well as photodetectors. More importantly, the provided synthesis method can pave the way toward tailoring the phase in MoS2 to promote the performance of electronic devices.

Abstract: A reversible phase transition in the whole semimetallic 1T?-tungsten disulfide (1T?-WS2) is realizable by proton intercalation and deintercalation, resulting in a newly-discovered semiconducting WS2 with a novel unconventional phase, denoted as 1T?d phase. A transport modulation with an on/off ratio of over 106 is realizable during the phase transition from the 1T?-WS2 to 1T?d-WS2. A transistor utilizing the advantage of reversible phase transition is developed by using a 1T?-WS2 nanosheet as a channel layer. A proton electrolyte contacts an edged circumference of the nanosheet for providing a reservoir of protons for proton intercalation and deintercalation of the nanosheet. The proton electrolyte is controllable by a gate-source voltage to intercalate or de-intercalate the nanosheet with protons for inducing a reversible phase transition over the nanosheet to thereby modify an electrical conductance of the channel layer or a spectral response of the channel layer to light.
