Flexibility meets rigidity: a self-assembled monolayer materials strategy for perovskite solar cells.

Self-assembled monolayer (SAM) materials have emerged as promising materials for interface engineering in perovskite solar cells. However, achieving an optimal balance between molecular packing density, charge transport efficiency, and defect passivation remains a challenge. In this work, we propose a SAM material design strategy that synergizes flexible head groups with rigid linking groups.

Self-assembled materials with an ordered hydrophilic bilayer for high performance inverted Perovskite solar cells.

While self-assembled material based inverted perovskite solar cells have surpassed power conversion efficiencies of 26%, enhancing their performance in large-area configurations remains a significant challenge. In this work, we report a self-assembled material based hole-selective layer 4-(7H-dibenzo[c,g]carbazol-7-yl)phenyl)phosphonic acid, with a π-expanded conjugation. The enhanced intermolecular π-π interactions facilitate the self-assembly of 4-(7H-dibenzo[c,g]carbazol-7-yl)phenyl)phosphonic acid molecules to form an ordered bilayer with a hydrophilic surface, which passivates the buried perovskite interface defect and enables high-quality and large-area perovskite preparation, while simultaneously enhancing interfacial charge extraction and transport.

Background: Rhinoplasty requires balanced consideration of function and aesthetics, necessitating a precise evaluation tool. A reliable and validated patient-reported measure, the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) evaluates both aspects but was previously unavailable in Chinese. This study fills that gap by providing a Chinese version.

HYDROGEN-RICH SALINE UPREGULATES THE SIRT1/NF-ΚB SIGNALING PATHWAY AND REDUCES VASCULAR ENDOTHELIAL GLYCOCALYX SHEDDING IN SEPSIS-INDUCED ACUTE KIDNEY INJURY.

Sepsis causes dysfunction in different organs, but the pathophysiological mechanisms behind it are similar and mainly involve complex hemodynamic and cellular dysfunction. The importance of microcirculatory dysfunction in sepsis is becoming increasingly evident, in which endothelial dysfunction and glycocalyx degradation play a major role. This study aimed to investigate the effects of hydrogen-rich saline (HRS) on renal microcirculation in septic renal failure, and whether Sirt1 was involved in the renoprotective effects of HRS.

Beyond genome: Advanced omics progress of Panax ginseng.

Ginseng is a perennial herb of the genus Panax in the family Araliaceae as one of the most important traditional medicine. Genomic studies of ginseng assist in the systematic discovery of genes related to bioactive ginsenosides biosynthesis and resistance to stress, which are of great significance in the conservation of genetic resources and variety improvement. The transcriptome reflects the difference and consistency of gene expression, and transcriptomics studies of ginseng assist in screening ginseng differentially expressed genes to further explore the powerful gene source of ginseng.

Significant Enhancement of Circular Polarization in Light Emission through Controlling Helical Pitches of Semiconductor Nanohelices.

Circularly polarized light emission (CPLE) can be potentially applied to three-dimensional displays, information storage, and biometry. However, these applications are practically limited by a low purity of circular polarization, i.e.

Ear reconstruction stage I: Minor modifications in sculpting the auricle support using the 7th and 8th costal cartilages.

Background: The verisimilitude of the reconstructed auricle and its long-term stability largely depends on the framework sculpting. This study described three kinds of minor modifications based on Firmin's way of sculpting the auricle framework and reported the clinical outcomes achieved with them.

Methods: We conducted a retrospective study of congenital microtia patients undergoing detail-improved auricular reconstruction from June 2016 to June 2020.

Auriculocondylar syndrome: Pathogenesis, clinical manifestations and surgical therapies.

Auriculocondylar syndrome (ARCND) is a genetic and rare craniofacial condition caused by abnormal development of the first and second pharyngeal arches during the embryonic stage and is characterized by peculiar auricular malformations (question mark ears), mandibular condyle hypoplasia, micrognathia and other less-frequent features. GNAI3, PLCB4 and EDN1 have been identified as pathogenic genes in this syndrome so far, all of which are implicated in the EDN1-EDNRA signal pathway. Therefore, ARCND is genetically classified as ARCND1, ARCND2 and ARCND3 based on the mutations in GNAI3, PLCB4 and EDN1, respectively.

Repair of Congenitally Defective Type of Earlobe Clefts With Residual Lobular Tissue: A Convenient and Effective Surgical Technique.

Background: For patients with a congenitally defective type of earlobe cleft, repair techniques similar to those utilized for earlobe lacerations are not suitable due to the presence of certain tissue defects. However, traditional earlobe reconstruction techniques imply the need to form complex flaps with adjacent normal tissues, which may lead to many complications.

Objectives: In this study, we developed a technique to repair the earlobe with residual lobular tissue based on the characteristics of congenitally defective earlobe clefts.

The effect of whole-body vibration on lower extremity function in children with cerebral palsy: A meta-analysis.

Objective: The aim of this meta-analysis was to evaluate the effect of whole-body vibration training on lower limb motor function in children with cerebral palsy in randomized-controlled trials (RCTs).

Methods: Two independent reviewers systematically searched the records of nine databases (PubMed, Cochrane, Web of Science, EMBASE, CNKI, etc.) from inception to December 2022.

Optimal nitrogen rate strategy for sustainable rice production in China.

Avoiding excessive agricultural nitrogen (N) use without compromising yields has long been a priority for both research and government policy in China. Although numerous rice-related strategies have been proposed, few studies have assessed their impacts on national food self-sufficiency and environmental sustainability and fewer still have considered economic risks faced by millions of smallholders. Here we established an optimal N rate strategy based on maximizing either economic (ON) or ecological (EON) performance using new subregion-specific models.

Nitrogen management to minimize yield-scaled ammonia emission from paddy rice in the Middle and Lower Yangtze River Basin: A meta-analysis.

Paddy fields in China contributed to one third of the global cropland ammonia (NH) emission inventory, while rice accounted for half of cereal consumption, necessitating exhaustive considerations of the balance between NH emissions abatement and food demand. The concept of yield-scaled emission intensity (emissions per unit crop production) has the potential to guide sustainable intensification strategies, yet its application to NH emissions remains poorly understood. Here, by constructing novel crop-specific models for single rice production and NH emissions in the Middle and Lower Yangtze River Basin (LYRB) as a case study, the relationships between fertilizer N application and yield-scaled NH were estimated.

Gold(I) Multi-Resonance Thermally Activated Delayed Fluorescent Emitters for Highly Efficient Ultrapure-Green Organic Light-Emitting Diodes.

Acceleration of singlet-triplet intersystem crossings (ISC) is instrumental in bolstering triplet exciton harvesting of multi-resonance thermally activated delayed fluorescent (MR-TADF) emitters. This work describes a simple gold(I) coordination strategy to enhance the spin-orbit coupling of green and blue BN(O)-based MR-TADF emitters, which results in a notable increase in rate constants of the spectroscopically observed ISC process to 3×10  s with nearly unitary ISC quantum yields. Accordingly, the resultant thermally-stable Au emitters attained large values of delayed fluorescence radiative rate constant up to 1.

An ultrasensitive hairpin sensor based on g-CN nanocomposite for the detection of miRNA-155 in breast cancer patient serum.

Achieving the early diagnosis of breast cancer, through ultrasensitive detection of tumor marker miRNA-155, is a significant challenge. Therefore, an ultrasensitive hairpin electrochemical biosensor based on graphite-like phase carbon nitride composite was proposed. In this paper, poly(D-glucosamine) (PDG) was used as a stabilizer and reducing agent to prepare gold nanoparticles at room temperature, and then a graphite-like phase with a two-dimensional lamellar structure carbon nitride was further combined with it to obtain the poly(D-glucosamine)/gold nanoparticles/graphite-like phase carbon nitride nanocomposite (PDG/AuNPs/g-CN), in order to achieve the goal of signal amplification.

Craniofacial multi-point fascial suspension combined with tongue-shaped flap for correction of cryptotia deformity.

Background: In this article, we will introduce a modified surgical approach to correct cryptotia (by suspending the auricular cartilage to the temporal region), which allows for a more visible and consistent surgical benefit than previous techniques that simply used flap accumulation.

Methods: We use several stitches to suspend the released auricular cartilage from the root of the auricular cartilage (approximately deep in the cavum conchae and the cymba conchae cartilage) to the temporal bone periosteum in a higher position, presumably similar to the principle of leverage, thus obtaining a larger auriculocephalic sulcus and a higher superior auricular pole.

Results: Over the past 5 years, this new technique was applied to the auricles of 20 patients between the ages of 15 and 40 years.

Accumulation of organic compounds in paddy soils after biochar application is controlled by iron hydroxides.

Soil acidity is one of the vital factors that influence organic matter transformation and accumulation. Long-term studies on the mechanisms of biochar's effects on soil organic matter (SOM) accumulation dependent on pH values are lacking. A four-year column experiment was conducted without and with biochar application (11.

Assessing the viability of soil successive straw biochar amendment based on a five-year column trial with six different soils: Views from crop production, carbon sequestration and net ecosystem economic benefits.

Converting straw to biochar (BC) followed by successive application to soil has been increasingly suggested as a multi-win approach for soil fertility improvement, carbon (C) sequestration and efficient disposal of straw residues in intensive cropping agroecosystems. However, different soil types response differently in terms of crop growth and non-CO greenhouse gas (GHG) emissions after BC application. Furthermore, few studies have comprehensively evaluated the net global warming potential (GWP) and net ecosystem economic benefits (NEEB) after long-term BC incorporation across representative soil types in China.
