Transition Metal Chalcogenides: Perspectives on Their Applications for Nitrate Reduction

ChemistryOpen, Volume 15, Issue 9, September 2026.
This review paper reports the syntheses, properties, and applications of TMCs for electrochemical reduction of nitrate to ammonia. Various studies revealed that the conversion of nitrate to ammonia is principally the electrocatalytic hydrogenation of nitrate and the rate and yield of ammonia is competitively challenged by hydrogen evolution reaction ...

Nabyta methemoglobinemia - opis przypadku [PDF]

, 2010
Methemoglobinemia; an increased concentration of methemoglobin in the blood, is an altered state of hemoglobin whereby the ferrous form of iron is oxidized to the ferric state, rendering the heme moiety incapable of carrying oxygen. The authors present a

The Atmospheric Pressure Microwave Plasma‐Assisted Synthesis of ZnO/Graphene Hybrid Composite for Nitrite Sensing

Nano Select, Volume 7, Issue 8, August 2026.
A sustainable two‐step approach is investigated for the synthesis of a ZnO/graphene hybrid composite using the atmospheric‐pressure microwave plasma method. ZnO and graphene are synthesized within minutes at a low microwave power of 300 W. The resulting hybrid material is employed as an electrode material for nitrite sensing.

Potassium hydroxide activation of microalgal biochar for improved adsorption efficiency

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1911-1922, July/August 2026.
Abstract Activated carbon was prepared from Chlorella by carbonization and potassium hydroxide activation, and its structural properties and methylene blue (MB) adsorption performance were evaluated. Raw Chlorella exhibited an adsorption capacity of 287.2 mg g−1, which decreased to 214.8 mg g−1 after carbonization.

Treatment for a rare case of phenazopyridine-induced methemoglobinemia: a case report and mini-review

Frontiers in Medicine
Methemoglobinemia is a condition caused by elevated levels of methemoglobin (MetHb) in the blood, a reduced form of hemoglobin that cannot properly bind to oxygen, interfering with delivery to tissues.

A Case Report of Acute-on-Chronic Methemoglobinemia

Clinical Practice and Cases in Emergency Medicine
Introduction: Methemoglobinemia is a rare hematologic disorder of hemoglobin, in which iron contained within the heme moiety becomes oxidized from ferrous iron to ferric iron at a concentration greater than 1% in the blood.

European S2k guidelines on management of autoimmune blistering diseases in children and adolescents

Journal of the European Academy of Dermatology and Venereology, Volume 40, Issue 7, Page 1137-1161, July 2026.
Autoimmune blistering disorders (AIBDs) in children are rare, challenging to diagnose and treat and often require immunosuppressants. Until now, no paediatric care guidelines existed. The EADV Task Force for AIBDs has developed the consensus‐based recommendations, enabling physicians to adopt a uniform, tailored treatment strategy to improve outcomes ...
