Limitrof ülke kavramı, tarih boyunca farklı kültürlerin ve imparatorlukların sınırlarında bulunan, genellikle stratejik ve jeopolitik önemi olan ülkeleri ifade etmiştir. Bu tür ülkeler genellikle büyük güçlerin etkisi altında kalmış, bazen bağımsızlık mücadeleleri vermiş ve-ya bağımsızlıklarını koruma amacıyla dengeleri sağlama çabası içinde politika sürdürmüş olup genellikle büyük güçlerle ilişkilerinin dinamikleri, güvenlik endişeleri ve coğrafi konumları nedeniyle önem taşırlar.
Sınır boyu devleti kavramı, özellikle Soğuk Savaş sonrası Sovyetler Birliği’nin dağılması akabinde Rusya çevresinde bağımsız-lığını kazanan eski Sovyet ülkelerinin bağımsızlıklarını kazandıktan sonra, jeopolitik olarak hala Rusya'nın etki alanında kalmış olmaları veya Rusya ile karmaşık ilişkiler içinde bulunmaları sebebiyle jeopolitik biliminin dikkatini çekmiştir. Zira bu ülkeler, bağımsızlık kazandıktan sonra hem kendi iç dinamikleri hem de bölgesel ve küresel oyuncularla olan ilişkileri nedeniyle jeopolitik bir odak noktası haline gelmiştir.
Dünya siyasetinin dinamik yapısı özellikle de 21. yy itibariyle "limitrof devlet" kavramı da değişen siyasi konjonktür kapsamında güncel örneklerle yeniden ele alınarak değerlendirilmelidir. Bu çalışmada, limitrof teorileri; fiziki sınır ve güç ekseninde limitrof devletler örneklemeleri; sınır jeopolitiği bağlamında limitrof devletlerin bağımsızlıklarını koruma çabaları ve limitrofu oldukları devlet ve yapılarla ilişkileri ele alınarak limitrof devlet kavramının 21. yy ekseninde güncellenme ihtiyacı ortaya konulacaktır.

Augmented reality, a superset if you like of virtual reality (VR), has really been hitting the headlines recently. Like 3D TV, its been a long time coming! Since ~1994 or earlier, there have been explorations of how molecular models can be transferred from actual reality to virtual reality using conventional computers (as opposed to highly specialised ones). It was around then that a combination of software (Rasmol) and

Authors: Melati Dewi Arum , Na'im Fira Nadlratan 
Published: October 2023

Indonesia is listed as the fifth biggest country with the biggest number of populations in the world population review with a population of approximately 275.7 million people. Indonesia also has high fertility rate which signifies a high demand in the market for meeting the production needs of diapers. Disposable diapers are one of the most purchased items by parents in general, yet they are also one of the most environmentally damaging waste products. Despite the fact that reusable diapers exist, consumer demand for disposable diapers is still rising. The prevalence of global issues and discussions regarding pollution and waste generation has received responses from various sectors of society, leading to the formation of movements and communities focused on environmental awareness. Mamaberclodi is an online community based for all mothers who use modern cloth diapers (clodi) for their children and the community pioneer who gives cloth diapers class online and free. In this article, we will explore the impact of Mamaberclodi as online communities on the issue of diapers waste in Indonesia. This research uses a qualitative approach which uses concurrent embedded design mixed method that combines qualitative and quantitative analysis. The qualitative analysis uses data from literatures review and depth interview, while the quantitative analysis uses Mamaberclodi data from their internal survey. Qualitative analysis is used to analyze interview data. Quantitative analysis uses statistical descriptive analysis to describe the data. This research provides the data from literature review, interviews from four informants, and Mamaberclodi internal data to conclude how this online community impacted the reduction of diaper waste in Indonesia. This research concludes that online communities, such as Mamaberclodi are needed to reduce the amount of waste generated. However, further research with more data is needed to support this research.

Maize ZmHSP90 plays a role in acclimation to salt stress
Authors: Yu Xinyan , Zhao Yanxin , Wang Yun , Zou Zhiqing , Li Fenghai 
Published: October 2023

Background
Maize is sensitive to salt stress, especially during the germination and seedling stages.

Methods
We conducted germination experiments on 60 maize materials under salt stress, and screened out the most salt-tolerant and salt-sensitive varieties based on germination indicators. Afterwards, transcriptome analysis was performed to screen for key regulators in the plumule and flag leaf at the germination and seedling stages, respectively. Following that, transgenic tobacco was developed to expose the roles and mechanisms of the candidate genes, enabling a deeper investigation of their functions.

Results
Out of the 60 inbred lines of maize, “975-12” exhibits the highest level of salt tolerance, while “GEMS64” displays the lowest. The application of salt stress resulted in a significant increase in the levels of antioxidant enzymes in both “975-12” and “GEMS64”. ABA signal transduction and jasmonic acid pathways were the pathways that mainly affected by salt stress. In addition, a significant finding has been made indicating that when exposed to high levels of salt stress, the expression of ZmHSP90 in ‘975-12’ increased while in ‘GEMS64’ decreased. Furthermore, in tobacco plants overexpressing ZmHSP90, there was an increase in antioxidant enzyme activity associated with salt tolerance. ZmHSP90 enhanced the expression levels of NtSOS1, NtHKT1, and NtNHX1 as compared to those in the salt treatment, causing the maintenance of Na+ and K+ homeostasis, suggesting that high expression of ZmHSP90 was conducive to regulate Na+ transporters to maintain K+/Na+ balanced in tobacco.

ObjectiveRheumatic diseases are characterized by different patterns of immune overactivation. This study investigated the correlation of whole blood type 1 interferon (IFN) stimulated gene (ISG), IL18, and CXCL9 expression with clinical disease activity in pediatric rheumatic diseases and assessed the required number of ISGs to be included in a composite type 1 IFN score.MethodsWhole blood‐derived RNA and clinical data were collected from 171 mostly pediatric patients with connective tissue diseases (CTDs), systemic autoinflammatory diseases (SAIDs), monogenic interferonopathies (IFNPs) and other inflammatory diseases, and from 38 controls. The expression of six previously established ISGs, IL18, and CXCL9 was assessed by real‐time polymerase chain reaction (471 samples). Individual and composite gene expression was assessed, and correlation and threshold analyses were performed.ResultsCorrelation between ISG expression and clinical disease activity was strongest in CTD, especially in juvenile dermatomyositis (JDM) and IFNP, and modest in patients with SAID. Threshold ISG expression levels for the detection of at least mild clinical disease activity were substantially higher in patients with systemic lupus erythematosus compared with JDM. The correlation of expression levels of limited sets of ISGs and even individual ISGs with clinical disease activity were not inferior to a composite score of six ISGs.ConclusionIn a real‐world cohort, individual ISG expression levels robustly reflected clinical disease activity in CTD and IFNP, especially in JDM, which would simplify such analyses in clinical routine and be more cost‐effective. Threshold levels varied across diseases, potentially reflecting different mechanisms of type 1 IFN overactivation.

Published: October 2023

AbstractMixtures between choline and geranic acid (CAGE) have previously been shown to insert into lipid bilayers. This may be useful for the transdermal delivery of larger pharmaceuticals, however, little is known about the mechanism of activity. By comparing the interactions between CAGE and lipid bilayers with those of a less‐active, yet closely‐related analogue, choline octanoic acid (CAOT), a chemical basis can be investigated. Overall, six systems are studied here by neutron reflectivity, where d54‐1,2‐dimyristoyl‐sn‐glycero‐3‐phosphocholine (DMPC) solid‐supported phospholipid bilayers are first formed on SiO2 substrates before exposure to the deep eutectic solvent (DES). Components of the DES could be identified within the bilayer by exploiting contrast variation and selective deuteration. CAGE is shown to be a mild disruptive agent, free to insert and diffuse across the bilayer, preserving much of the bilayer integrity. Experiments identify co‐mingling of geranate ions inhibits the efficient packing of lipid tails, increasing hydration across the bilayer. Conversely, CAOT is found to both exchange and remove lipid molecules to achieve incorporation, inducing swelling and the formation of solvent patches. It appears these behaviors derive from the structures of the anions and thus amphiphilicity of the DES, laying the foundations for the rational design and optimization of these candidates toward transdermal delivery.

AbstractThe remarkable success of lead halide perovskites (LHPs) in photovoltaics and other optoelectronics is significantly linked to their defect tolerance, although this correlation remains not fully clear. The tendency of LHPs to decompose into toxic lead‐containing compounds in the presence of humid air calls for the need of low‐toxicity LHP alternatives comprising of cations with stable oxidation states. To this aim, a plethora of low‐dimensional and wide‐bandgap perovskite‐inspired materials (PIMs) are proposed. Unfortunately, the optoelectronic performance of PIMs currently lags behind that of their LHP‐based counterparts, with a key limiting factor being the high concentration of defects in PIMs, whose rich and complex chemistry is still inadequately understood. This review discusses the defect chemistry of relevant PIMs belonging to the halide elpasolite, vacancy‐ordered double perovskite, pnictogen‐based metal halide, Ag‐Bi‐I, and metal chalcohalide families of materials. The defect‐driven optical and charge‐carrier transport properties of PIMs and their device performance within and beyond photovoltaics are especially discussed. Finally, a view on potential solutions for advancing the research on wide‐bandgap PIMs is provided. The key insights of this review will help to tackle the commercialization challenges of these emerging semiconductors with low toxicity and intrinsic air stability.
Liquid Metal‐Based Sensor Skin Enabling Haptic Perception of Softness

Published: October 2023

AbstractHaptic perception of softness is a unique feature of the human skin that relies on the concurrent measurements of the lateral deformation and compression of the skin during object manipulation. This is challenging to implement in robotics because of combined requirements in sensing modalities, skin format, robotic structures, and synthetic materials. A soft sensory skin supporting distributed and bimodal mechanical sensing over large surface area and suitable for robotic hand manipulation is reported. Resistive pressure and strain sensors are prepared with spray‐coated liquid metal films embedded in a silicone matrix. Object softness is computed through a calibrated model based on both sensor response curves and the stiffness of the carrier robot. The soft sensory skin enables localization and discrimination of softness that promise interesting future implementation for robotic palpation or precise teleoperation.

Published: October 2023

AbstractA detailed investigation addressing the effects of functionalizing conjugated polymers with oligo(ethylene glycol) (EGn) sidechains on the performance and polymer‐electrolyte compatibility of electrochromic devices (ECDs) is reported. The electrochemistry for a series of donor‐acceptor copolymers having near‐infrared (NIR)‐optical absorption, where the donor fragment is 3,4‐ethylenedioxythiophene (EDOT) or an EGn functionalized bithiophene (g2T) and the acceptor fragment is diketopyrrolopyrrole (DPP) functionalized with branched alkyl or EGn sidechains, is extensively probed. ECDs are next fabricated and it is found that EGn sidechain incorporation must be finely balanced to promote polymer‐electrolyte compatibility and provide efficient ion exchange. Proper electrolyte‐cation pairing and polymer structural tuning affords a 2x increase in optical contrast (from 12% to 24%) and >60x reduction in switching time (from 20 to 0.3 s). Atomic force microscopy (AFM)/grazing incidence wide‐angle X‐ray scattering (GIWAXS) characterization of the polymer film morphology/microstructure reveals that an over‐abundance of EGn sidechains generates large polymer crystallites, which can suppress ion exchange. Lastly, time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) indicates sidechain/electrolyte identity does not influence the electrolyte penetration depth into the films, and EGn sidechain inclusion increases electrolyte cation uptake. The material structural design insight and guidelines regarding the polymer‐electrolyte ion insertion/expulsion dynamics reported here should be of significant utility for developing next‐generation mixed ionic‐electronic conducting materials.
Ultrathin Hematite‐Hercynite Films for Future Unassisted Solar Water Splitting
Authors: Chnani Ahmed , Knauer Andrea , Strehle Steffen 
Published: October 2023

AbstractPhotoelectrochemical (PEC) water splitting requires stable, efficient, and cost‐effective photoelectrodes to enable future large‐scale solar hydrogen production. Ultrathin hematite‐hercynite photoanodes that meet all these criteria in an excellent way is presented here. Hematite‐hercynite photoelectrodes are synthesized in a self‐forming manner by thermal oxidation of iron–aluminum alloy films and characterized with regard to water splitting applications. Photoanodes fabricated from 17 wt.% Al at 493 °C for 8 h and 685 °C for 5 min exhibit, for instance, a photocurrent density of 1.24 and 1.53 mA cm−2 at 1.23 V versus RHE, respectively, as well as superior light absorption in the visible range of the solar spectrum. The PEC performance improvement in comparison to pure hematite thin film electrodes is first achieved by adjusting the aluminum concentration with an optimum range of 12–17 wt.% and second by optimizing the annealing conditions. The resulting photocurrent densities are about a factor of three higher than those obtained from electrodes synthesized from pure iron thin films using the same synthesis conditions. Finally, it is shown that ultrathin hematite‐hercynite photoelectrodes enable even unassisted solar water splitting in a NaOH (1 m) electrolyte with a maximum solar‐to‐hydrogen conversion efficiency of 0.78%.

AbstractMagnetic micropillars have shown great promise in various applications including information storage, fluid manipulation, and soft robotics. But to date, magnetic micropillars with reprogrammable magnetization, multi‐modal deformation and functionality, and on‐demand fast actuation have not been reported yet. Herein, locally reprogrammable ferromagnetic micropillars with on‐demand reconfiguration and multi‐functionality are reported. The magnetic micropillars are fabricated by dispersing CrO2 microparticles (diameter ≈5 µm, Curie temperature Tc = 110 °C) in the Ecoflex matrix. The magnetization of each micropillar can be easily programmed and reprogrammed by simultaneously heating the micropillar above Tc via laser and applying a magnetizing field. The magnetization can be programmed as omnidirectional in three dimensions, thus entire magnetic micropillar arrays show a variety of deformation modes (including both synchronous and asynchronous modes) with on‐demand fast actuation by remotely applying magnetic fields. Four representative functionalities of the magnetic micropillars are demonstrated: information encryption, particle pumping, ink mixing, and underwater crawling robot.

Published: October 2023

AbstractOcean research currently relies heavily on bulky bioelectronic tags and sensory telemetry networks for data collection. Therefore, in this study, a compact and flexible waterproof bioelectronic tag with a kirigami (paper cutting)‐based design for underwater conductivity, temperature, depth, and strain sensing is designed and evaluated. Unlike invasive bioelectronic tags, the kirigami bioelectronic tag can be attached to robotic fish or aquatic animals without harming the host. The kirigami‐based design facilitates excellent stretchability and reduces stress within the sensor, thus inhibiting crosstalk induced by movement during multimodal sensing. A working bioelectronic tag is fabricated and tested. Notably, the performance of the kirigami sensors shows very little degradation even after >1000 stretching cycles. Specifically, the multimodal bioelectronic tag demonstrates a wide working pressure range of 0–5.0 MPa, and the kirigami design effectively suppresses signal coupling. The kirigami‐based bioelectronic tag is applied to a robotic dolphin and underwater environmental parameters and detailed movement parameters, such as swing angle, swing frequency, and typical gestures are detected simultaneously with high sensitivity and accuracy. Therefore, the device can be applied to a broad range of applications in various fields such as behavioral biology, ocean informatics, and underwater robotics.
