Always provide the correct name of the employee as shown on the social security card in this box. Enter the correct SSN of the employee in this box even if it was shown correctly on the form you want to amend If you wish to amend the information provided on the Forms Form W-2VI, W-2AS, W-2GU, W-2CM, or W-2C, indicate 4 digits to specify the year and the letters "AS," "CM," "GU," "VI," or "C" to specify the form you want to correct If you are submitting this document to correct Form W-2, provide all 4 digits of the year you correcting the form. As an alternative, furnish the IRS W-2C Form containing the correct address in Block I and all other correct information to the employee but do not send the Copy A to the SSA The new copies must include the phrase "Reissued Statement". Just issue a corrected Form W-2 with the proper address to the affected employee. Do not file the Form W-2C with the SSA to correct the wrong address.Use a separate Form W-3C for each type of the Form W-2 you correct.
If you need to correct a name or a Social Security number of an employee, fill our boxes D through I only.Use the following tips to prepare and submit the form properly: This work presents a new route to accomplish the morphology control, composition and electronic regulation so as to boost the HER performance of tungsten-carbide-based electrocatalysts, providing new guidance for exploring efficient noble-metal-free electrocatalysts.IRS Form W-2C consists of the six copies that are distributed in the same way as copies of Form W-2. Furthermore, the one-dimensional (1D) nanowire morphology and graphite-like carbon shells also promote the conductivity of the whole electrocatalytic material. DFT calculations and experimental results demonstrate that such prominent performance towards the HER was mainly attributed to abundant interfaces between WC and W 2C phases in the cable-like heterojunction nanowires which may exert both the high HER activity of W 2C and the excellent electrochemical stability and conductivity of WC. With the optimized phase composition, WC/W NWs (WC : W 2C ≈ 1 : 1.3) display the low overpotentials of 69 mV and 56 mV at the cathodic current density of 10 mA cm −2 and small Tafel slopes of 52 and 59 mV dec −1 in 0.5 M H 2SO 4 and 1 M KOH, respectively. Herein, ultrafine cable-like WC/W 2C heterojunction nanowires (NWs) covered by few-layer N-doped graphite-like carbon (labeled WC/W NWs) have been firstly accomplished via a simple two-step pyrolysis treatment of W 18O 49 NWs precursor, exhibiting tunable phase composition, excellent HER activity, fast kinetic metrics and remarkable stability along the entire pH range. Developing highly active, durable and economical noble-metal-free electrocatalysts for the hydrogen evolution reaction (HER) plays a crucial role in the future hydrogen economy.
