Bipyridine-based conjugated microporous polymers for boosted photocatalytic U(VI) separation.

Incorporating bipyridine units into the matrix of conjugated microporous polymers (CMPs) boosts exciton dissociation, charge separation, and oxidation capacity. Consequently, the bipyridine-modified CMPs exhibit an impressive U(VI) separation rate (404 μmol g h) under sacrificial agent-free conditions, outperforming the results of its counterparts without bipyridine units and other documented CMPs.

A Lightweight and High-Precision Passion Fruit YOLO Detection Model for Deployment in Embedded Devices.

In order to shorten detection times and improve average precision in embedded devices, a lightweight and high-accuracy model is proposed to detect passion fruit in complex environments (e.g., with backlighting, occlusion, overlap, sun, cloud, or rain).

The relationship between teacher support and positive emotions in Chinese higher vocational students: multiple mediating effects of procrastination behavior and interpersonal assistance.

Background: In China, more than 5 million students enter higher vocational colleges each year, and the positive emotions of their students merits much attention.

Purpose: This study aimed to explore the effect of teacher support on positive emotions among higher vocational students by further investigating the mediating role of procrastination behavior and interpersonal assistance.

Methods: A questionnaire survey was conducted with 676 higher vocational students from Zhejiang Province, China.

[Retrospective study on incomplete intestinal obstruction treated with the adjuvant therapy of acupuncture and moxibustion].

Objective: To evaluate the clinical effects on incomplete intestinal obstruction treated with the adjuvant therapy of acupuncture and moxibustion.

Methods: Using the retrospective analysis, 80 patients of incomplete intestinal obstruction were divided into an observation group and a control group, 40 cases in each one. In the control group, the routine treatment was given, such as fasting, gastrointestinal decompression, parenteral nutrition, infection prevention with antibiotics and enema laxative.

Influence of Chloride-Ion Adsorption Agent on Chloride Ions in Concrete and Mortar.

The influence of a chloride-ion adsorption agent (Cl agent in short), composed of zeolite, calcium aluminate hydrate and calcium nitrite, on the ingress of chloride ions into concrete and mortar has been experimentally studied. The permeability of concrete was measured, and the chloride ion content in mortar was tested. The experimental results reveal that the Cl agent could adsorb chloride ions effectively, which had penetrated into concrete and mortar.
