Efficient and Stable Inverted Perovskite Solar Cells Enabled by Inhibiting Voids via a Green Additive.

The buried interface in inverted perovskite solar cells (PSCs) is critical for determining device performance. However, during annealing, the perovskite crystallized downward from the film's top surfaces, and the use of dimethyl sulfoxide (DMSO) often resulted in voids at the perovskite bottom surface, which negatively impacted PSC performance. In this study, a green solid-state additive, piracetam (PA), was introduced into a perovskite precursor to reduce void formation.

Diffusible Signal Factor-Mediated Quorum Sensing Modulates Swarming in .

spp. are plant pathogens known for significantly impacting crop yields. Among them, () is notable for colonizing the xylem and causing sugarcane leaf scald disease.

[Clinical study of electroacupuncture therapy on postoperative rehabilitation of patients with knee fractures].

Objective: To investigate the effect of electroacupuncture therapy on postoperative rehabilitation training of patients with knee fractures.

Methods: Patients with knee fractures from July 2020 to July 2021 were randomly assigned to either the experimental group or a control group according to the double-blind principle. Both groups were given surgical treatment and postoperative conventional rehabilitation training.

Effectiveness of Enhanced Recovery After Surgery-Based Respiratory Function Exercise in Elderly Patients with Lung Cancer and its Effect on Postoperative Functional Recovery.

Objective: To investigate the effect of enhanced recovery after surgery-based respiratory function exercise in elderly lung cancer patients and its impact on postoperative functional recovery.

Methods: A total of 109 elderly lung cancer patients admitted to our hospital between January 2020 and January 2021 were included in the study. The patients were randomly assigned to either the control group (n = 52), receiving conventional care, or the research group (n = 57), receiving enhanced recovery after surgery-based respiratory function exercise in addition to conventional care.

Higher TIGITCD226 γδ T cells in Patients with Acute Myeloid Leukemia.

The diverse structural and functional heterogeneity of γδ T cells is related to their distinct role in cancer immunity. The different phenotypes of γδ T cells in patients with acute myeloid leukemia (AML) is far from clear. In particular, the expression pattern of co-inhibitory and co-stimulatory receptors on γδ T cells remains unknown.

Long-Term Tea Consumption Is Associated with Reduced Risk of Diabetic Retinopathy: A Cross-Sectional Survey among Elderly Chinese from Rural Communities.

Aim: To investigate the association between variables related to tea consumption (duration, frequency, and type) and the risk of diabetic retinopathy.

Methods: A rural community-based, cross-sectional survey was conducted in Weitang Town, Suzhou, China. People aged 60 years or above were invited to complete the survey.

Real-time monitoring of the penetration of amphiphilic acrylate copolymer in leather using a fluorescent copolymer as tracer.

A fluorescent tracer, poly (acrylic-co-stearyl acrylate-co-3-acryloyl fluorescein) [poly (AA-co-SA-co-Ac-Flu)], used for real-time monitoring the penetration of amphiphilic acrylate copolymer, poly (acrylic-co-stearyl acrylate) [poly (AA-co-SA)], in leather was synthesized by radical polymerization of acrylic, stearyl acrylate and fluorescent monomer, 3-acryloyl fluorescein (Ac-Flu). The structure, molecular weight, introduced fluorescent group content and fluorescent characteristics of the fluorescent tracer and target copolymer, amphiphilic acrylate copolymer, were also characterized. The results show that the tracer presents the similar structural characteristics to the target and enough fluorescence intensity with 1.
