Las Tecnologías de la Información y Comunicación (TIC), se encuentran totalmente difundidas en nuestra sociedad actual, tanto es así que ya no es extraño ver a cualquier persona llevando y/o utilizando un móvil o un ordenador con observable asiduidad. Por otra parte, tampoco es menos cierto el hecho de que las mismas se constituyen como una de las herramientas de más utilidad hoy en día, muchas son las ventajas que estas presentan, permiten desde facilitar la comunicación o relaciones hasta comprar sin salir de casa, por ejemplo. Sin embargo, no todo en ellas es positivo, en los últimos tiempos se está constatando el nacimiento de un nuevo fenómeno que afecta especialmente a niños/as y/o adolescentes, y es que, son cada vez más frecuentes los casos en los que éstos desarrollan patrones de conducta nocivos o adictivos en relación con el uso de las TIC. Este hecho, hace que todo en la vida de dichos/as niños/as y/o adolescentes cambie de manera radical al verse afectados numerosos aspectos o ámbitos de la misma como por ejemplo, el familiar, uno de los contextos más damnificados al ser el más próximo o cercano. En base a esto, a lo largo de este artículo se realizará un recorrido por alguna de las cuestiones que giran en torno a una adicción a las TIC, haciendo especial mención a la perspectiva del Trabajo Social en relación con este tema.
Information and Communication Technologies (ICT), are fully disseminated in our current society, so much so that it is no longer strange to see anyone carrying and/or using a mobile or a computer with observable assiduity. On the other hand, it is not less true fact that they are constituted as one of the most useful tools today, there are any advantages that they present, they allow from facilitating communication or relationships to buying without leaving home, for example. However, not everything in them is positive, in recent times the birth of a new phenomenon that especially affects children and/or adolescents is being verified, and that is, the cases in which these are increasingly frequent develop harmful or addictive behavior patterns in relation to the use of ICT. This fact, makes everything in the life of such children and/or adolescents change radically as many aspects or areas of it are affected, such as family, one of the most affected contexts to be the closer or closer. Based on this, throughout this article there will be a tour of some of the issues that revolve around an addiction to ICT, making special mention of the perspective of Social Work in relation this issue.

Los cambios que se están produciendo en la sociedad actual también manifiestan nuevas necesidades en la manera de despedirnos y recordarnos, lo que afecta directamente a la arquitectura funeraria de tanatorios y sobre todo de cementerios. A través de la «arquitectura emocional» se puede intervenir en los cementerios existentes para mejorar la percepción que transmiten a los usuarios y naturalizar los procesos de pérdida. En las futuras ampliaciones o construcción de nuevas instalaciones y/o cementerios deben tenerse en cuenta todas estas cuestiones de la arquitectura que conecta con las personas.
The changes that are taking place in today's society also show new needs in the way we remind ourselves, which directly affects funerary architecture of funeral parloursand especially in cemeteries. Through the «emotional architecture» we can intervene in existing cemeteries to improve the perception which they transmit to users and thus naturalize loss processes. All these issues of the architecture that connects with the people must be taken into account in the future enlargements or construction of new facilities and/or cemeteries.

Affective Neuroscience and Adult Education
Authors: Taylor Kathleen 
Published: December 2024

ABSTRACTThe expanding field of affective neuroscience is redefining the role of emotions in cognition, reasoning, and judgment. This contradicts long‐standing assumptions about cognition that consider emotions antithetical to learning. Emotions arose early in human brain development as essential to survival by directing the embodied brain toward life‐sustaining and away from life‐threatening environments. Metaphorical language, which emerges from embodied experience, is also necessary for thinking, reasoning, and learning. The brain's right hemisphere (RH) is the primary site for understanding figurative and symbolic language. Educational environments emphasize the left hemisphere's capacity for syntactic language and direct, linear thought. Though the RH has a more comprehensive view of reality, its contributions may be ignored or dismissed because it communicates metaphorically and symbolically. Drawing on elements of affective neuroscience, embodied emotions, and hemispheric difference may provide educators with new awareness in reconstructing adult learning environments with the embodied brain in mind.

AbstractPredicting the power conversion efficiency (PCE) using machine learning (ML) can effectively accelerate the experimental process of perovskite solar cells (PSCs). In this study, a high‐quality dataset containing 2079 experimental PSCs is established to predict PCE values using an accurate ML model, achieving an impressive coefficient of determination (R2) value of 0.76. In the 12 validation experiments with PSCs, the average absolute error between the observed and predicted PCE values is only 1.6%. Leveraging the recommended improvement solutions from the ML model, the device's PCE to 25.01% in experimental PSCs is successfully enhanced, thus truly realizing the objective of machine learning‐guided experiments. In addition, by improving the PCE of specific devices, the predicted value can reach 28.19%. The ML model has provided feasible strategies for experimentally improving the PCE of PSCs, which play a crucial role in achieving PCE breakthroughs.

Published: December 2024

AbstractLi‐rich Mn‐based (LRM) cathode materials, characterized by their high specific capacity (>250 mAh g−¹) and cost‐effectiveness, represent promising candidates for next‐generation lithium‐ion batteries. However, their commercial application is hindered by rapid capacity degradation and voltage fading, which can be attributed to transition metal migration, lattice oxygen release, and the toxicity of Mn ions to the anode solid electrolyte interphase (SEI). Recently, the application of LRM cathode in all‐solid‐state batteries (ASSBs) has garnered significant interest, as this approach eliminates the liquid electrolyte, thereby suppressing transition metal crosstalk and solid–liquid interfacial side reactions. This review first examines the historical development, crystal structure, and mechanisms underlying the high capacity of LRM cathode materials. It then introduces the current challenges facing LRM cathode and the associated degradation mechanisms and proposes solutions to these issues. Additionally, it summarizes recent research on LRM materials in ASSBs and suggests strategies for improvement. Finally, the review discusses future research directions for LRM cathode materials, including optimized material design, bulk doping, surface coating, developing novel solid electrolytes, and interface engineering. This review aims to provide further insights and new perspectives on applying LRM cathode materials in ASSBs.

AbstractRecently, slippery liquid‐infused porous surface (SLIPS) is widely utilized for anti‐icing. Nevertheless, a major challenge hindering the practical applications of SLIPS is the depletion of lubricating oil, significantly deteriorating its deicing performance. Given that super‐slippery effects are not required during most non‐icing periods, this research introduces a novel dynamic wettability‐adjustable SLIPS anti‐icing coating inspired by the nepenthes. This coating‐comprising modified diatomaceous earth and soft silicone rubber‐releases lubricating oil only when temperatures fall below −2 °C, thus exhibiting super‐slippery characteristics and effectively preventing icing. The porous modified diatomaceous earth retains lubricating oil for prolonged periods and facilitates its controlled release under external forces. The high elasticity and strength of the soft silicone rubber endow the coating with thermal expansion and contraction capabilities, enabling the active absorption and release of lubricating fluid in response to temperature variations. This coating, prepared using a straightforward strategy, demonstrates an ice adhesion strength and an oil loss rate of less than 23 kPa and 13%, respectively, after 50 icing/de‐icing cycles. These findings highlight the remarkable performance of the coating, providing valuable insights for achieving long‐term anti‐icing on the external surfaces of equipment in extreme working conditions.

AbstractPrecious metal electrical contact materials are pivotal in microelectronic devices due to their excellent chemical stability and electrical properties. Their practical application is hindered by the strength, contact resistance, and high cost. Multi‐principal elements alloys (MPEAs) provide the possibility to develop cost‐effective materials with enhanced mechanical properties. To address this, a novel precious metal MPEA, PdAgCuAuPtZn alloy, is designed, which exhibits significant solid solution strengthening and aging strengthening effects. The ultimate tensile strength increases from 747 MPa in the solution state to 1126 MPa in the aged state, while resistivity remains low. This study presents the first systematic investigation into the strengthening mechanisms of precious metal MPEAs using nanoindentation technology. These findings indicate that the aging strengthening of the alloy is attributed to spinodal decomposition (SD) and chemical short‐range order (CSRO) in the matrix. Furthermore, the precipitation structure with Cu‐rich and Ag‐rich phases gradually replaces the matrix, primarily accounting for aging softening. Additionally, it is discovered that precipitation structure can be strengthened by CSRO formed in the Cu‐rich phase, thus providing an innovative strengthening in PdAgCuAuPtZn alloy. These results will be beneficial to both deeply understanding the aging behaviors of PdAgCuAuPtZn alloys and designing high‐performance precious metal MPEAs.

AbstractVitrimer is a new, exciting class of sustainable polymers with healing abilities due to their dynamic covalent adaptive networks. However, a limited choice of constituent molecules restricts their property space and potential applications. To overcome this challenge, an innovative approach coupling molecular dynamics (MD) simulations and a novel graph variational autoencoder (VAE) model for inverse design of vitrimer chemistries with desired glass transition temperature (Tg) is presented. The first diverse vitrimer dataset of one million chemistries is curated and Tg for 8,424 of them is calculated by high‐throughput MD simulations calibrated by a Gaussian process model. The proposed VAE employs dual graph encoders and a latent dimension overlapping scheme which allows for individual representation of multi‐component vitrimers. High accuracy and efficiency of the framework are demonstrated by discovering novel vitrimers with desirable Tg beyond the training regime. To validate the effectiveness of the framework in experiments, vitrimer chemistries are generated with a target Tg = 323 K. By incorporating chemical intuition, a novel vitrimer with Tg of 311–317 K is synthesized, experimentally demonstrating healability and flowability. The proposed framework offers an exciting tool for polymer chemists to design and synthesize novel, sustainable polymers for various applications.

AbstractEffective regulation and reconstruction of the microenvironment are critical for the regeneration of chronic wounds. Diabetic wounds, in particular, pose a significant clinical challenge due to increased oxidative stress and dysfunctional healing processes. In this study, a novel therapeutic strategy is developed using 3D copper‐magnesium bimetallic antioxidant nano‐enzymes (Cu/Mg‐MOF) to mitigate reactive oxygen species (ROS) and restore redox balance through electron transfer. To optimize delivery, a thermo‐sensitive hydrogel composed of chitosan (CS) and ε‐polylysine (PL) is designed, serving as an efficient carrier for the nano‐enzymes. This Cu/Mg‐MOF@CS/PL hydrogel exhibits excellent physical properties, including injectability, softness, and biocompatibility, making it ideal for application in diabetic wounds. In a diabetic wound model, treatment with Cu/Mg‐MOF@CS/PL hydrogel significantly accelerated wound healing, with a closure rate of 90.6% by day 14, compared to just 55.4% in the untreated group. The hydrogel effectively promoted key aspects of wound healing, such as collagen deposition, re‐epithelialization, angiogenesis, and immunomodulation. These findings underscore the potential of the Cu/Mg‐MOF@CS/PL hydrogel as a promising therapeutic system for enhancing the healing of diabetic wounds.

Published: December 2024

AbstractCurvature‐induced interfacial electric field effects and local strain engineering offer a powerful approach for optimizing the intrinsic catalytic activity of single‐atom catalysts (SACs). Investigations into the surface curvature on SACs are still ongoing, and the impact of the concave surface is often overlooked. In this work, theoretical calculations indicate that curved surfaces, particularly those with concavity, can optimize the electronic structures of single Fe sites and facilitate the reductive release of *OH. A carbon sphere featuring uniformly oriented channels and a chiral multi‐shelled carbon hollow nanosphere are selected as carbon matrices due to their accessible concave and/or convex surfaces. After loading Fe species, the resulting catalysts with Fe SA in curved surfaces exhibit excellent oxygen reduction reaction activity (E1/2 = ≈0.89 V), strong methanol tolerance, and favorable long‐term stability. Impressively, a solid‐state flexible Zn–air battery based on this catalyst exhibits a remarkable durability over 40 h with a high peak power density of 122.1 mW cm−2 and excellent charge–discharge performance at different bending angles. This work offers in‐depth insights into the rational design of carbon supports with highly curved surfaces, offering new opportunities for the microenvironmental regulation of SACs at the atomic level.
Bifunctional Design of Ferroelectric‐Order and Band‐Engineering in Cu:KTN Crystal for Extended Self‐Powered Photoelectric Response

Published: December 2024

AbstractPhotoelectric conversion in ferroelectric crystals can support many important applications in modern on‐chip technology, but suffering from two problems, low responsive current and narrow responsive range. Especially, wide‐gap ferroelectric oxides are only active at short‐wavelength ultraviolet region with weak photocurrent at nanoampere levels. Here, a bifunctional design strategy of ferroelectric‐order and electronic‐band to improve the photocurrent and extend the responsive range simultaneously, is proposed. In a Cu‐doped KTa1−xNbxO3 (KTN) perovskite crystal, a conductive channel is constructed by “head‐to‐head” ferroelectric domains, associated with the emergence of micrometer‐scale supercells. In addition, the introduction of Cu+ ion can induce defect levels, thus extending the responsive range beyond the inherent absorption of pure KTN. Through rational device optimization, a record self‐powered responsivity of 5.23 mA W−1 is realized in Cu:KTN photodetector, which is two orders of magnitude higher than undoped KTN crystal. The temperature‐dependent light diffraction and photocurrent show that the ferroelectric‐order is dominated in this photoresponse behavior. Moreover, Cu:KTN detector is active in the broadband range from 390 to 1030 nm, covering ultraviolet, visible, and near‐infrared regions. This work provides an effective method for the design of next‐generation self‐powered photodetectors with ultrahigh responsivity and ultrawide responsive range.

Published: December 2024

AbstractPhase change memories (PCMs) are at the heart of modern memory technology, offering multi‐level storage, fast read/write operations, and non‐volatility, bridging the gap between volatile DRAM and non‐volatile Flash. The reversible transition between amorphous and crystalline states of phase‐change materials such as GeTe or Ge2Sb2Te5 is at the basis of PCM devices. Despite their importance, PCM devices face challenges including high power consumption during the RESET operation. Current research efforts focus on improving device architecture and exploring alternative phase‐change materials such as GeTe/Sb2Te3 super‐lattices (SLs), for which a reduced programming power consumption is observed compared with standard PCMs. Herein, by combining X‐ray diffraction and scanning transmission electron microscopy imaging of SL thin films with the study of the same SL in PCM devices, it is shown that it is possible to significantly decrease RESET energy of the device, without modifying the SL composition, by reducing the amount of structural defects through annealing treatment. The best device properties are obtained after transforming the SL into a defect‐free, highly out‐of‐plane oriented rhombohedral phase. These results offer a promising avenue for further improving the performance of SL‐based PCM devices through structural optimization.
Tunneling Dielectric Thickness‐Dependent Behaviors in Transistors Based on Sandwiched Small Molecule and Insulating Layer Structures

Published: December 2024

AbstractThis work demonstrates the floating gate devices featuring a small molecule‐insulator‐small molecule‐insulator sandwiched structure, where the versatile electrical characteristics can be achieved depending on the thickness of the intermediate parylene tunneling dielectric layer (TDL). For the thin parylene layer of 15 nm (parallel DNTT channel transistor), channel also forms in the lower DNTT layer, allowing hole carriers to tunnel through the parylene TDL. The parallel DNTT channel transistor exhibits electrical characteristics similar to a conventional DNTT transistor with the increased contact resistance due to the presence of the intermediate parylene layer. When the parylene TDL is slightly thicker to be 45 nm, negative differential transconductance followed by current saturation behavior is observed, due to tunneling through the parylene TDL. Finally, photomemory is demonstrated with the sufficiently thick parylene layer (≈80 nm), where hole carriers injected from the electrode cannot tunnel through the parylene TDL, allowing the lower DNTT layer to act as a floating gate for the photogenerated charge carriers. This photomemory shows programmability under the light illumination with the specific wavelength as well as the robust retention and endurance characteristics. Furthermore, the photomemory has been successfully implemented on flexible paper substrates.
