Efficient Light Harvester Layer Prepared by Solid/Mist Interface Reaction for Perovskite Solar Cells.

A solid/mist reaction method is developed to produce well-crystallized light harvester layers without pinhole defects for perovskite solar cells. The reaction based on mist precursor can be facilely operated with low process temperature. And it can effectively control the volume of CH3NH3I solution and the reaction temperature, which affect the quality of perovskite harvester layers and the performance of perovskite solar cells remarkably.

Transjugular insertion of bare-metal biliary stent for the treatment of distal malignant obstructive jaundice complicated by coagulopathy.

Purpose: This study was designed to investigate retrospectively the feasibility of transjugular insertion of biliary stent (TIBS) for the treatment of distal malignant obstructive jaundice complicated by coagulopathy.

Methods: Between April 2005 and May 2010, six patients with distal malignant obstructive jaundice associated with coagulopathy that was unable to be corrected underwent TIBS at our institution for the palliation of jaundice. Patients' medical record and imaging results were reviewed to obtain information about demographics, procedure details, complications, and clinical outcomes.

The amplatzer vascular plug: a review of the device and its clinical applications.

The Amplatzer Vascular Plug (AVP) is an established embolic device that can be an excellent alternative to coils or detachable balloons to embolize medium to large vessels with high flow. The device is easy to use and can be precisely deployed in the target vessel with high resistance to migration and a low recanalization rate. The technical success of this device is high, indications for use are expanding, and no absolute contraindications have been reported.

[The diagnostic value of digital subtraction angiography in detecting small intestinal bleeding].

Objective: To determine the diagnostic value of digital subtraction angiography (DSA) in detecting small intestinal bleeding.

Methods: DSA was performed in 39 patients with suspected small intestinal bleeding. The sensitivity, specificity and accuracy of DSA were evaluated in the 25 patients who accepted surgical treatment.
