Electrochemical Activation of Atomic Layer-Deposited Cobalt Phosphate Electrocatalysts for Water Oxidation.

The development of efficient and stable earth-abundant water oxidation catalysts is vital for economically feasible water-splitting systems. Cobalt phosphate (CoPi)-based catalysts belong to the relevant class of nonprecious electrocatalysts studied for the oxygen evolution reaction (OER). In this work, an in-depth investigation of the electrochemical activation of CoPi-based electrocatalysts by cyclic voltammetry (CV) is presented.

Charge carrier dynamics and photocatalytic activity of {111} and {100} faceted AgPO particles.

Silver orthophosphate is a highly promising visible light photocatalyst with high quantum yield for solar driven water oxidation. Recently, the performance of this material has been further enhanced using facet-controlled synthesis. The tetrahedral particles with {111} exposed facets demonstrate higher photocatalytic performance than the cubic particles with {100} exposed facets.

Solar Hydrogen Generation from Ambient Humidity Using Functionalized Porous Photoanodes.

Solar hydrogen is a promising sustainable energy vector, and steady progress has been made in the development of photoelectrochemical (PEC) cells. Most research in this field has focused on using acidic or alkaline liquid electrolytes for ionic transfer. However, the performance is limited by (i) scattering of light and blocking of catalytic sites by gas bubbles and (ii) mass transport limitations.

Pain and Anxiety versus Sense of Family Support in Lung Cancer Patients.

Lung cancer is a stressful condition for both patient and family. The anxiety and pain accompanying cancer and its treatment have a significant negative influence on the patient's quality of life. The aim of this study was to investigate the correlation between anxiety, pain, and perceived family support in a sample of lung cancer patients.

Complete cytoreduction combined with early postoperative intraperitoneal chemotherapy for ovarian carcinosarcoma. Report of two cases.

Background/aims: The purpose of the study is to report two long-term survivors with ovarian carcinosarcomas, which are rare intrapelvic malignancies with unfavorable prognosis.

Methods: Two middle-aged women with palpable abdominal tumors underwent complete cytoreductive surgery and no macroscopic tumor was left behind. Early postoperative intraperitoneal chemotherapy with doxorubicin was used as an adjuvant treatment.
