Income Tax Disclosure [Text Block]	NOTE 9: INCOME TAXES As of September 30, 2020 and December 31, 2019, the Company has provided a full valuation allowance against all of the net deferred tax assets. This was based on management's assessment, including the last two years of operating losses, that it is more likely than not that the net deferred tax assets may not be realized in the future. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) was enacted by the United States Congress. As a result of the enactment of the CARES Act, net operating losses (“NOL's”) can now be carried back for five years and resulted in the Company recognizing approximately $1.5 million of a tax benefit, of which $.8 million is a receivable at September 30, 2020. We continue to evaluate for potential utilization of the Company's deferred tax asset, which has been fully reserved for, on a quarterly basis, reviewing our economic models, including projections and timing of orders, the commencement of operations of the CVD Materials segment and cost containment measures.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
