Crueldad contra personas LGBTIQ+ y poder soberano en las nuevas formas de la guerra
Authors: Bello Urrego Alejandra del Rocío 
Published: July 2023

Objetivo/contexto: a partir del caso colombiano, se propone una inter- pelación del concepto de soberanía en la teoría política crítica contemporánea des- de una perspectiva feminista, queer y decolonial, a través del análisis del rol de la crueldad contra personas LGBTIQ+ en el establecimiento de una forma de poder soberano parainstitucional en las guerras neoliberales. Metodología: se trata de una investigación teórica apoyada en el análisis documental de los informes del Centro Nacional de Memoria Histórica de Colombia. Conclusiones: se demuestra que la circulación colonial y cisheteropatriarcal de la crueldad es un elemento esencial en la instauración de un poder disciplinario que afecta a la sociedad en su conjunto y que establece una forma específica de poder soberano. Esta forma actualiza, en la etapa neoliberal del capital, un gobierno de los cuerpos que distingue entre ciuda- danía y sujetos coloniales, y que es constitutiva del Estado nación. Originalidad: demostrar esta hipótesis tiene como consecuencia develar una forma específica de ejercicio del poder que produce cuerpos por medio del establecimiento de lo que de- nomino gobierno del sufrimiento, al que defino como el control, la racionalización y la administración del sufrimiento. Esta forma del poder desborda el marco de lectura propuesto por los paradigmas de la biopolítica y de la necropolítica, por lo que, con el fin de abarcar esta dimensión de lo político, propongo el concepto de pathospolítica, entendida como la forma del poder que convierte el sufrimiento en objeto de gobierno y que se despliega a través de este gobierno.
“The General Said”
Authors: Cheshmedzhieva-Stoycheva Desislava 
Published: July 2023

Times of trial require resorting to new methods for venting up the tension. Internet memes during the first outbreak of the pandemic proved to be the necessary outlet, while, at the same time, provided a platform for the public to share their opinion, albeit in a humorous way, on the measures imposed, the people involved in the fight against the virus, and basically on everything that determined their everyday lives. The latter has been fostered greatly by the fact that humour is a generally relatable phenomenon. At the same time though, it can also be culture specific and some peculiarities of the embedded message can remain hidden for the general public. In order to trace these opposing aspects in the creation of internet memes, the paper analyses a corpus of 84 memes circulated on Facebook and Instagram in the period of 13 March 2020 – 30 May 2020. The subject in all these memes is General Ventsislav Mutafchiyski, who was in charge of the struggle with COVID-19 pandemic in Bulgaria, and the main methods of analysis are Critical Discourse Analysis (CDA) and Multimodal Discourse Analysis.
The focus is on intertextuality and the paper argues that some of the intertextual links used in the creation of the memes might be left misunderstood by the general public due to the specificity of the message carried or the images that have been selected by the authors of these pieces of digital humour. Thus, mediation, i.e. the time needed to decode the message, would be longer for people who are not familiar with the images or ideas used, while smaller for those aware of them. Additionally, the paper argues that the age of the recipients as well as their personal preferences are also of significance for the proper understanding of the message a meme carries. Furthermore, the analysis also proves the fact that although some images might be used simply as a background and do not carry substantial information, without them one cannot understand the full array of ideas the author/ poster of a particular meme is trying to convey.

The present investigation was conducted on 1-month-old seedlings from March 2022 to Jan 2023 to find out the suitable treatment for growth, yield and quality of Papaya cv. Red Lady. The statistical design adopted for the experiment was randomized block design (RBD) with three replications and ten treatment combinations. viz, T0 (Control), T1(NAA 100 ppm), T2 ( NAA 150 ppm), T3 (NAA 200 ppm), T4 (GA3 100 ppm), T5 (GA3 150 ppm), T6 (GA3 200 ppm), T7 (CCC 500 ppm), T8 (CCC 750 ppm), T9 (CCC 1000 ppm). The treatments were applied by soil drenching at the initiation of the experiment, vegetative phase, pre-flowering and fruit setting stage to assess the effect on growth, yield and quality of papaya. The results of the present investigation revealed that the treatment T6 (GA3 200 ppm) outstand in all the aspects like maximum plant height (142.13 cm), number of functional leaves per plant (17.14), stem diameter (54.37 mm) minimum days to first flowering (95.42), no. of flowers per plant (56.09), no. of fruit per plant (23.12), fruit weight (1263.38 gm), fruit yield/plant (29.22 kg), yield (129.85 t/ha­-1), fruit length (20.49 cm), fruit diameter (18.21 cm) and quality parameters like maximum TSS (16.61 ºBrix) and acidity (0.125 %), non-reducing sugar (2.16 ºBrix), reducing sugar (7.83 ºBrix), total sugar (9.99 ºBrix) followed by T5 (GA3 150 ppm). The lowest observation was recorded in T0 (Control). Treatment with GA­3, NAA and CCC improved vegetative growth, yield and quality to a lesser extent as compared to the control. That’s why a positive response has to be seen in particular treatment during the research trial.

Published: July 2023

AbstractStrain‐engineering of materials encompasses significant elastic deformation and leads to breaking of the lattice symmetry and as a consequence to the emergence of optical anisotropy. However, the capability to image and map local strain fields by optical microscopy is currently limited to specific materials. Here, a broadband scanning reflectance anisotropy microscope as a phase‐sensitive multi‐material optical platform for strain mapping is introduced. The microscope produces hyperspectral images with diffraction‐limited sub‐micron resolution of the near‐normal incidence ellipsometric response of the sample, which is related to elastic strain by means of the elasto‐optic effect. Cutting edge strain sensitivity is demonstrated using a variety of materials, such as metasurfaces, semiconductors, and metals. The versatility of the method to study the breaking of the lattice symmetry by simple reflectance measurements opens up the possibility to carry out non‐destructive mechanical characterization of multi‐material components, such as wearable electronics and optical semiconductor devices.

AbstractOrganic memory has attracted tremendous attention for next‐generation electronic elements for the molecules’ striking ease of structural design. However, due to them being hardly controllable and their low ion transport, it is always essential and challenge to effectively control their random migration, pathway, and duration. There are very few effective strategies, and specific platforms with a view to molecules with specific coordination‐groups‐regulating ions have been rarely reported. In this work, as a generalized rational design strategy, the well‐known tetracyanoquinodimethane (TCNQ) is introduced with multiple coordination groups and small plane structure into a stable polymers framework to modulate Ag migration and then achieve high‐performance devices with ideal productivity, low operation voltage and power, stable switching cycles, and state retention. Raman mapping demonstrates that the migrated Ag can specially coordinate with the embedded TCNQ molecules. Notably, the TCNQ molecule distribution can be modulated inside the polymer framework and regulate the memristive behaviors through controlling the formed Ag conductive filaments (CFs) as demonstrated by Raman mapping, in situ conductive atomic force microscopy (C‐AFM), X‐ray diffraction (XRD) and depth‐profiling X‐ray photoelectron spectroscopy (XPS). Thus the controllable molecule‐mediated Ag movements show its potential in rationally designing high‐performance devices and versatile functions and is enlightening in constructing memristors with molecule‐mediated ion movements.

AbstractSoft robots are composed of compliant materials that facilitate high degrees of freedom, shape‐change adaptability, and safer interaction with humans. An attractive choice of material for soft robotics is crosslinked networks of liquid crystal polymers (LCNs), as they are responsive to a wide variety of external stimuli and capable of undergoing fast, programmable, complex shape morphing, which allows for their use in a wide range of soft robotic applications. However, unlike hydrogels, another popular material in soft robotics, LCNs have limited applicability in flooded or aquatic environments. This can be attributed not only to the poor efficiency of common LCN actuation methods underwater but also to the complicated relationship between LCNs and water. In this review, the relationship between water and LCNs is elaborated and the existing body of literature is surveyed where LCNs, both hygroscopic and non‐hygroscopic, are utilized in aquatic soft robotic applications. Then the challenges LCNs face in widespread adaptation to aquatic soft robotic applications are discussed and, finally, possible paths forward for their successful use in aquatic environments are envisaged.

Published: July 2023

AbstractThe debye length is a measure of the distance over which the electric field of a charged particle decays in an electrolyte solution. If the binding of the analyte to the surface of the transducer is too far away from the surface, the electric field to the analyte may decay over a distance greater than the debye length thereby reducing the sensitivity of the measurement. In this context, this study has developed a simple one‐step protein immobilization strategy to covalently attach proteins on the sensor surface. Our binding strategy, which uses hydrogen peroxide (H2O2) ensures that the analyte is attached as close as possible to the transducer surface. This study evaluates our findings by comparing our strategy with silane chemistry and elucidating the debye length effects with colorimetric assays and field effect devices. Additionally, as a case study, we also evaluated the performance of our methodology for the detection of glucose oxidation by a field effect device. Overall, the developed immobilization strategy avoids the effects of the debye length and improves the performance of the biosensor.

Published: July 2023

AbstractBacteria are difficult to be eliminated because of their multi‐drug resistance, which brings significant threats to public health. Among the antibacterial methods, mechanobactericidal surfaces provide a possible approach to solving this problem. In this study, a generally used mechanical sterilization is developed by fabricating a nanostructured coating. The functional coating is simply fabricated by growing zeolitic imidazolate frameworks (ZIFs, ZIF‐8 mixed with ZIF‐67) nanospikes on the surface of the fabric substrate in situ. The fabricated ZIF nanospikes are stable and effective, with the sterilization efficiency approaching 99.9999%. This technique provides a fast, safe, and low‐cost antibacterial method without drug resistance, which can be potentially used in hospitals, emergency treatments, and superbug protection in the future.

AbstractRapid and eco‐friendly preparation of biomedical materials is significant for practical applications. This study proposes a simple two‐step method for preparing silver nanoparticles (AgNPs)‐functionalized gauze dressings (Ag‐Q‐G) with antibacterial activity in a green and time‐efficient manner that requires <10 min. A smooth and uniform quercetin coating is formed on the gauze fibers using alkali–acid redeposition for 10 s. Subsequently, AgNPs are rapidly formed (in 5 min) and firmly deposited on the quercetin‐coated gauze by ultraviolet irradiation in an AgNO3 solution. The in vitro results indicate that Ag–Q–G exhibits excellent antibacterial activity, with a rate of 99.57% ± 0.52% against Staphylococcus aureus and 95.59% ± 1.50% against Escherichia coli, while maintaining acceptable cytocompatibility. An animal study reveals that Ag‐Q‐G reduces infection and promotes wound healing in a rat dorsal total cortical wound model. This approach provides a practical option for the commercial production of antibacterial gauze dressings.

AbstractBioinspired nanoplasmonic 3D crossed surface relief gratings and metasurfaces are fabricated on azobenzene molecular glass thin films to create effective antibacterial surfaces. A synergetic mechanical and photothermal interaction at the interface between the nanostructures and the Escherichia coli (E. coli) bacteria results in a significant decrease in the viable bacterial population. In particular, combined exposure to the interfacial nanospikes as well as the evanescent blue and red electromagnetic fields induced by the nanoplasmonic metasurface, results in a 97% reduction of the viable E. coli in only 25 min, when illuminated with a low‐power white light.
Rigorous Modal Analysis of Chiral Nanoparticles

AbstractThe physical origins of the chiroptical response from nanostructures are highly demanded for chiral photonics. The chiroptical response of a nanoparticle, whether measured along specific incident directions of exciting waves (when immobilized onto a substrate) or in solution through averaging responses across all structure orientations, is believed to stem from the interplay between three key factors: geometrical chirality, far‐field chirality, and near‐field chirality. This study aims to understand the relationship among these factors using a rigorous quasinormal mode (QNM) expansion method. By decomposing circular dichroism (CD) spectra into individual QNM contributions, it is observed that the chiroptical response with respect to incident directions depends on the extent of field overlapping between the QNM and light. In contrast, the near‐field optical chirality (OC) is determined by the QNMs of the nanoparticle, independent of external excitations. As a proof‐of‐concept, a nanohelix metasurface is proposed that employs lossless gold and exploits the physics of bound states in the continuum to maximize the CD signal.

AbstractPerovskite single crystals (SCs) have gained significant interest in various applications owing to their superior optoelectrical and physical characteristics as compared to polycrystalline films. However, a considerable portion of incident light is typically reflected at the surface of perovskite SCs, leading to insufficient light absorption within the crystal bulk, ultimately resulting in reduced performance of SC‐based photodetectors. In the present work, an inverted pyramid‐shaped structure is in situ introduced on the surface of an MAPbBr3 SC during the crystal growth process, which can reduce light reflection in the surface region and enhance light absorption of the SC. Additionally, the hydrophobic small molecule copper (II) phthalocyanine (CuPc) is thermally evaporated onto the SC, forming a CuPc/MAPbBr3 heterojunction for the first time. The CuPc/pyramid‐shaped MAPbBr3 heterojunction‐based photodetector exhibits self‐powered characteristics and superior optoelectrical performance, achieving a photocurrent of greater than 10−5 A (10−7 A), a responsiveness of 257 mA W−1 (8.84 mA W−1), and a detection rate of 2.98 × 1012 Jones (1.02 × 1011 Jones) at −2 V (0 V) bias. Simultaneously, the device demonstrates excellent long‐term stability under high humidity conditions, retaining 90.5% of its initial photocurrent even after 60 days in a 60–80% humidity environment.

AbstractCadmium sulfide (CdS) buffer layer is commonly used in Kesterite Cu2ZnSn(S,Se)4 (CZTSSe) thin film solar cells. However, the toxicity of Cadmium (Cd) and perilous waste, which is generated during the deposition process (chemical bath deposition), and the narrow bandgap (≈2.4 eV) of CdS restrict its large‐scale future application. Herein, the atomic layer deposition (ALD) method is proposed to deposit zinc–tin‐oxide (ZTO) as a buffer layer in Ag‐doped CZTSSe solar cells. It is found that the ZTO buffer layer improves the band alignment at the Ag‐CZTSSe/ZTO heterojunction interface. The smaller contact potential difference of the ZTO facilitates the extraction of charge carriers and promotes carrier transport. The better p–n junction quality helps to improve the open‐circuit voltage (VOC) and fill factor (FF). Meanwhile, the wider bandgap of ZTO assists to transfer more photons to the CZTSSe absorber, and more photocarriers are generated thus improving short‐circuit current density (Jsc). Ultimately, Ag‐CZTSSe/ZTO device with 10 nm thick ZTO layer and 5:1 (Zn:Sn) ratio, Sn/(Sn + Zn): 0.28 deliver a superior power conversion efficiency (PCE) of 11.8%. As far as it is known that 11.8% is the highest efficiency among Cd‐free kesterite thin film solar cells.

AbstractHybrid two‐dimensional materials consisting of graphene and hexagonal boron nitride (h‐BN) have drawn significant interest due to their tunable bandgap and electrical properties. Considering their composition‐dependent properties, ohmic current injection and the development of h‐BN‐based optoelectronic and high‐power electronic devices should be achievable by controlling the C concentration. In this study, electrical and optical characterizations of single‐crystal h‐BN synthesized under high‐pressure and high‐temperature (HPHT) are conducted by varying C concentrations via post‐growth diffusion. Low C‐doped h‐BN (h‐BN:C) with ≈0.1 at% C exhibits nonohmic conduction within a voltage range of ±100 V at all temperatures. In contrast, high h‐BN:C (≈10 at% C) containing C domains and graphite/graphene layers shows additional luminescence peaks and initially exhibits nonohmic conduction at 298 K, which then transforms to ohmic conduction after breakdown‐like behavior at 598 K. This phenomenon, observed only in the high h‐BN:C devices, is attributed to the C‐containing conductive path formed on the channel surface through C drift and local dielectric breakdown of h‐BN mother phase, indicating that ohmic conduction itself does not guarantee the current flow in the conduction/valence bands in h‐BN:C. With these findings, the present thorough and fruitful characterizations are beneficial for the development of h‐BN:C‐based devices.
