This is consistent with the formation of topological edge states, which delimit four ribbon-like topologically different regions top and bottom topologically trivial ‘ribbons’ (where the electric field has induced a topological phase transition) that are adjacent to two topologically nontrivial ‘ribbons’ located at opposing sides of the nanotube.…[Read more]

Chitin was converted into chitosan with a 70-80% degree of deacetylation (DDA) in a short period while using homogenous conditions. These promising results provide the first proof of concept of the ability of BetG and [Ch]ClLA-based DESs to be used as a greener approach for the chitin homogeneous N-deacetylation. © 2020 Wiley Periodicals, Inc.The…[Read more]

Emphysema sequentially leads to the loss of gas exchanging surface and an abnormal shape of the diaphragm generating dyspnea refractory to standard medical therapy. Lung volume reduction surgery (LVRS) is a surgical treatment option for patients with severe emphysema whose symptoms are uncontrolled on standard therapy. Bronchoscopic LVR (bLVR) is…[Read more]
