Potential Water Collection From Air by Chloride Perovskites.

Directly capturing water from the air has become a compelling strategy to secure water resources. Yet, challenges persist with sorption-based hygroscopic materials, such as inadequate water adsorption efficiency, material degradation post-adsorption, and the need for energy input during water collection. This study introduces an alternative category of sorbent materials potentially for atmospheric water harvesting-metal chloride perovskites-that exhibit spontaneous water vapor adsorption and liquid water collection.

Mallard hindlimbs locomotion system respond to changes in sandy ground hardness and slope.

Mallards inhabit soft grounds such as mudflats, marshes, and beaches, demonstrating remarkable proficiency in traversing these grounds. This adeptness is closely linked to the adjustments in the operation of their hindlimbs. This study employs high-speed videography to observe postural adjustments during locomotion across mudflats.

Active Adaptive Strategies of Mallard Feet in Response to Changes in Wetness and Compactness of the Sand Terrain.

Mallards (Anas platyrhynchos) exhibit exceptional locomotive abilities in diverse terrains, such as beaches, swamps, and tidal flats. This capability is primarily attributed to their unique webbed toe structure and cooperative locomotion posture of their feet. Therefore, this study aims to further delve into the active adaptive strategies of mallard feet in response to diverse external environmental conditions.

From the Analysis of Anatomy and Locomotor Function of Biological Foot Systems to the Design of Bionic Foot: An Example of the Webbed Foot of the Mallard.

This study utilized the mallard's foot as the subject, examining the bone distribution via computed tomography (CT) and analyzing pertinent parameters of the tarsometatarsal bones. Additionally, gross anatomy methods were employed to elucidate the characteristics of the toes and webbing bio-structures and their material composition. Biologically, the mallard's foot comprises tarsometatarsal bones and 10 phalanges, enveloped by fascia, tendons, and skin.

Protocol for isothermal crystallization of photovoltaic perovskite films based on volatile solvents.

The efficient functioning and stability of a perovskite photoactive layer are paramount to the performance of solar cell devices. Here, we present a protocol for the synthesis of a high-performance exemplified methylammonium lead iodide (CHNHPbI or MAPbI) perovskite photoactive layer. We describe steps for preparing the requisite ratios of the precursor powders, synthesizing MAPbI single crystals, and selecting a suitable preparation technique.

Tooth autotransplantation gives teeth a second chance at life: A case series.

Traditional transplantation, surgical extrusion and intentional replantation procedures are important treatment options that clinicians may consider performing in their daily clinical practice. There should be a well-constructed treatment plan for teeth with problems. In this paper, we present a series of case reports on three treatment methods used in autologous tooth transplantation and a literature review on the prevention of postoperative complications and the advantages of autologous tooth transplantation compared to dental implantation.

Evaluation of staff satisfaction after the implementation of a daily goals sheet in the routine work of an oral outpatient department and its influence on work efficiency.

Background: In March 2021, the supervision group of our hospital inspected the daily work of the outpatient department in the branch and found many problems in the process, such as an excessive number of daily check-up forms, nurses' confusion regarding the daily check-up process, and the omission of daily check-up items. Therefore, focusing on these problem, our hospital established a quality improvement team to conduct a status survey and perform this study. This study evaluated the feasibility, availability and sustainability of using a daily goals sheet in the routine work of a stomatological outpatient department and investigated the satisfaction of the nursing staff with the sheet.

Pilot study of minimum occlusive force of vascular clamps on arterial vessels in rats.

Our aims were to determine the accuracy of an improved formula for determining the minimum occlusive force (MOF) of a vascular clamp on rats' abdominal aortas, compare our findings with the calculated theoretical MOF, and provide reference data for clinical research and development of medical instruments that cause minimal damage. We created a vessel closure model and developed a formula for calculating the theoretical MOF of arterial vessels when they are occluded. This formula utilises the blood pressure in the blood vessel, its diameter, and the width of the vascular clamp.

[Left mandibular infantile myofibromatosis: a case report].

Infantile myofibromatosis is a rare benign childhood myofibroblastoma. A case of infantile myofibromatosis of the left mandible was reported, and relevant literature was reviewed to discuss the clinical characteristics, pathogenesis, imaging characteristics, pathological characteristics, differential diagnosis, and the treatment of the tumor to improve the understanding of the tumor.
