MgAc-Modified SnO Electron Transport Layer for Highly Efficient and Thermal Stable Perovskite Solar Cells.

There are always defects and oxygen vacancies in SnO prepared by solution methods, hindering efficient carrier transfer between SnO and the perovskite in perovskite solar cells. Thus, we employed MgAc to modify the interface. Carboxyl groups of MgAc filled the oxygen vacancies in SnO, reducing its surface defect density, and Mg partially replaced surface Sn, improving the properties of the SnO layer.

Effect of ABX site changes on the performance of tin-lead mixed perovskite solar cells.

Tin-lead mixed perovskite solar cells (TLMPSCs), with the advantage of approaching the Shockley-Queisser (S-Q) limit for photovoltaic applications, have been rapidly developed and achieved a power conversion efficiency (PCE) of 23.7%.

Orchestration of MUC2 - The key regulatory target of gut barrier and homeostasis: A review.

The gut mucosa of human is covered by mucus, functioning as a crucial defense line for the intestine against external stimuli and pathogens. Mucin2 (MUC2) is a subtype of secretory mucins generated by goblet cells and is the major macromolecular component of mucus. Currently, there is an increasing interest on the investigations of MUC2, noting that its function is far beyond a maintainer of the mucus barrier.

FEATURES OF DIAGNOSIS AND ADVERSE COURSE OF NEONATAL JUVENILE XANTHOGRANULOMA: CASE REPORT.

The work describes a case of rare neonatal systemic juvenile xanthogranuloma with an initial damage of the scalp, limbs, back and abdomen, multiple damages of the parenchyma of both lungs, spleen and liver with the development of a severe form of congenital cholestatic hepatitis. The diagnosis was established on the basis of histopathological and immunohistochemical examination of the skin nodules. The child on the background of therapy under the Langerhans cell histiocytosis III program achieved a partial response, which was manifested by a reduction of granulomatous formations on the skin, elimination of liver failure, but retained hepatosplenomegaly, specific lesions of the lung parenchyma, liver, and left kidney.

However, controversy has widely existed in materials characterization and photocatalytic activity evaluation.

White Cord Syndrome After Cervical or Thoracic Spinal Cord Decompression. Hemodynamic Complication or Mechanical Damage? An Underestimated Nosographic Entity.

The ischemia/reperfusion mechanism is believed to be responsible for parenchymal damage caused by temporary hypoperfusion and worsened by the subsequent attempt of reperfusion. This represents a true challenge for physicians of several fields, including neurosurgeons. A limited number of papers have shed the light on a rare pathologic condition that affects patients experiencing an unexplained neurologic deficit after spine surgery, the so-called "white cord syndrome.
