Asplenium adulterinum Milde represents one of the natural heritages which have to be protected due to their scientific importance. In the actual context of global warming with myriad effects on biodiversity, the ex-situ conservation of A. adulterinum should be a priority. The possibility to obtain genetically stable individuals through in vitro techniques is a requirement of ex situ conservation. The genetic similarity of A. adulterinum gametophytes maintained 8 years in vitro culture was assessed. Explants represented by gametophyte fragments were analyzed for genetic stability through RAPD.

New technologies of reintroduction of plant species presuppose implementing both traditional and biotechnological methods for obtaining certain planting materials. However, plants cultivated in vitro exist in specific conditions that lead to changes in their structural and functional state. This explains why it is hard for them to adapt to ex vitro and in situ conditions. Therefore, there is a need for the development of a multistage method of cultivating in vitro plants that would make the influence on their adaptive mechanism in ex vitro and in situ conditions possible.

The calibration of liquid crystals has been considered essential to obtain accurate heat transfer measurements. Nevertheless, liquid crystal aging, illumination, and ex situ calibration effects remain a difficult and might influence the heat transfer level. Proposed here is to bypass liquid crystal calibration by utilizing the evolution of the wall temperature gradients.

AbstractActive pharmaceutical ingredients have emerged as an environmentally undesirable element because of their widespread exploitation and consequent pollution, which has deleterious effects on living things. In the pursuit of sustainable environmental remediation, biomedical applications, and energy production, there has been a significant focus on two-dimensional materials (2D materials) owing to their unique electrical, optical, and structural properties. Herein, we have synthesized 2D zinc oxide nanosheets (ZnO NSs) using a facile and practicable hydrothermal method and characterized th

AbstractElectrocatalytic hydrogen evolution reaction (HER) is widely regarded as one of the most efficient and sustainable strategies for hydrogen production. Up to now, most electrocatalysis research related to HER mainly focuses on stand‐alone electrocatalysis and fails to pay attention to the integration of other driving forces such as light. Herein, Cu2O nanostructures with different exposed crystal facets were synthesized by wet chemical methods for electrocatalytic HER, and it was found that the octahedral Cu2O nanostructures with exposed crystal planes of (111) (O‐Cu2O) had the best hyd

Abstract Background Visualization of cancer during breast conserving surgery (BCS) remains challenging; the BCS reoperation rate is reported to be 20-70% of patients. An urgent clinical need exists for real-time intraoperative visualization of breast carcinomas during BCS. We previously demonstrated the ability of a prototype imaging device to identify breast carcinoma in excised surgical specimens following 5-aminolevulinic acid (5-ALA) administration. However, this prototype device was not designed to image the surgical cavity for remaining carcinoma after the excised lumpectomy specimen is

Lygodium sp. is a climbing fern that occurs in open forests, settling frequently in areas with disturbed vegetation. In Argentina, Lygodium venustum inhabits in the protected area "Moconá" Provincial Park, in few and small populations. In-vitro cultivation of spores is a strategy for ex-situ conservation of species with reduced or threatened populations. Usually, fern spores need to be surface sterilized before sowing, to avoid the development of unwanted microorganisms. As part of our project focused on the conservation of native fern species in Argentina, the aim of this work was to evaluate

AbstractHeteroatoms doping would validly stabilize the structure of Li‐rich material and elevate electrochemical performance. For the synthesized Li‐rich material, the conventional ex situ doping strategy can only incorporate heteroatoms in the outer particles, diminishing benefits for the internal structure of secondary particles. Recently, in situ doping has been employed to influence topological lithiation and achieve well‐distribution in the bulk structure. However, the mechanisms of in/ex situ doping on elevating electrochemical performance for Li‐rich material are ambiguous. Herein, by i

Much has been reported about optogenetic based cardiac arrhythmia treatment and the corresponding characterization of photostimulation parameters, but still, our capacity to interact with the underlying spatiotemporal excitation patterns relies mainly on electrical and/or pharmacological approaches. However, these well-established treatments have always been an object of somehow heated discussions. Though being acutely life-saving, they often come with potential side-effects leading to a decreased functionality of the complex cardiac system. Recent optogenetic studies showed the feasibility of

AbstractConstructing an all‐in‐one wearable electronic system integrated with an energy‐harvesting, an energy‐storing, and a working unit can fundamentally solve the problems of sustainable energy supply, miniaturization, and lightweight for further commercialization. Here, an all‐in‐one wearable system consisting of solar cell, cathode‐free zinc ion micro‐battery (ZIMB) and piezoresistive pressure sensor is proposed, achieving an ultralong and stable power supply. Under the action of photocurrent, this integrated system is stimulated to in situ generate MnO2 on the initial cathode‐free substr

AbstractOne of the main material properties altered by rare earth additions in magnesium alloys is texture, which can be specifically adjusted to enhance ductility and formability. The current study aims at illuminating the texture selection process in a Mg–0.073at%Gd–0.165at%Zn alloy by investigating recrystallization nucleation and early nucleus growth during static recrystallization. An as-cast sample of the investigated alloy was deformed in uniaxial compression at 200 °C till 40% strain and was then cut into two halves for subsequent microstructure characterization via ex situ and quasi i

Introduction: Google Autocomplete Algorithms Despite recent attention to the impact of social media platforms on political discourse and public opinion, most people locate their news on search engines (Robertson et al.). When a user conducts a search, millions of outputs, in the form of videos, images, articles, and Websites are sorted to present the most relevant search predictions. Google, the most dominant search engine in the world, expanded its search index in 2009 to include the autocomplete function, which provides suggestions for query inputs (Dörr and Stephan).
