Authors: Aguilar Carrasco María Teresa , López Lovillo Remedios María 
Published: December 2021

The significance of facilities in Architecture is quite unknown in the society in which we live, even for future architecture students. Relegating the facilities to the background is habitual and it causes operation problems, visually pollution and it affects inhabitants’ comfort. Furthermore, basic aspects for users’ health such as indoor air quality are not usually included in the architectural process. Can this be avoided by making the students aware of the importance of integrating the facilities and the aspects they cover? Is the root of the problem in the way of teaching these subjects? To give an answer to these questions, the Architecture Zero Course has been used to force a first critical reflection on these issues, using gamification and ICT. This experience results are key to focus teaching in the facilities subjects of the degree.
El alcance de las Instalaciones en la Arquitectura es bastante desconocido en la sociedad en la que nos encontramos, incluso para los futuros estudiantes de Arquitectura. Lo habitual es relegar las instalaciones a un segundo plano causando problemas de funcionamiento, contaminando visualmente y afectando al confort de los habitantes. Además, aspectos fundamentales para la salud del usuario como la calidad del aire no suelen incluirse en el proceso arquitectónico. ¿Se puede evitar esto concienciando previamente a los estudiantes de la importancia de la integración de las instalaciones y de los aspectos que abarcan? ¿Está la raíz del problema en la docencia de estas asignaturas? Para responder a estas preguntas se ha utilizado el Curso Cero de Arquitectura para forzar una primera reflexión crítica sobre estos temas, usando la gamificación y las TIC. Los resultados de esta experiencia son claves para enfocar la docencia en las asignaturas de Instalaciones del Grado.

Published: December 2021

This text addresses the architectural methodology developed during the first term of the 2019 academic year at the Design Studio I-II, School of Architecture, San Sebastián University, Chile, in response to the XIV Corma Competition: “Theatre: timber and edge”. In the Design Studio, ways of making forms in art were transferred to architecture through the adoption of strategies taken from Land Art to design a theatre built in timber at the edge between land and sea in Lota, Chile. A theatre from where it is possible to contemplate both the shows held within and the landscape itself by means of a simple and regular geometric shape placed in nature that is capable of turning topography into a place. An artificial shape that turns nature into a new landscape.

New teacher functions in cyberspace - on technology, mass media and education
Authors: Buhl Mie 
Published: December 2021

Information technology allows the education system to do its job in new ways. Conceptions of what it means to be educated are changing both for teachers and for students. A teacher’s professional duties are not limited to acting as a disseminator of knowledge and facilitating learning processes for the student. Teachers must also relate their position to new constructions of time and space. However, these new constructions of what it is to be an actor in time and space mean that some of the functions that have as a matter of course been assembled in the person of the teacher have been displaced into other positions. Information technology exposes the teacher’s performative choice in how teachers act in certain situations, which intensifies reflexivity. This article is about how teachers must meet increasing expectations to perform on the premises of mass media and how this displaces the premises for educational practice. Specific examples will be provided from a situation in the master’s program in media and ICT.
Adaptive practical fixed‐time tracking control for uncertain non‐strict‐feedback systems with input delay and prescribed boundary constraints
Authors: Zhang Xu , Tan Jieqing , Yao Yangang , Wu Jian 
Published: December 2021

SummaryThis article concentrates upon the practical fixed‐time adaptive neural tracking control problem of non‐strict‐feedback nonlinear systems with input delay and prescribed boundary constraints (PBCs). A modified appropriate auxiliary system is introduced to eliminate the complex calculations appeared in the input delay. The unknown nonlinear functions exist in non‐strict‐feedback nonlinear systems, which are approximated by the radial basis function neural networks. The adaptive practical fixed‐time control strategy is developed based on a novel coordinate transformation by utilizing the backstepping algorithm. Under the proposed controller, it can be guaranteed that the tracking error satisfies the PBCs in fixed time and all the signals in the closed‐loop system are bounded. Some numerical simulations verify the effectiveness of the control approach.

Published: December 2021

AbstractMicroscale laser emissions have emerged as a promising approach for information encoding and anti‐counterfeiting for their feature‐rich spectra and high sensitivity to the surrounding environment. Compared with artificial materials, natural responsive biomaterials enable a higher level of complexity and versatile ways for tailoring optical responses. However, precise control of lasing wavelengths and spatial locations with biomolecules remains a huge challenge. Here, a biologically programmable laser, in which the lasing can be manipulated by biomolecular activities at the nanoscale, is developed. Tunable lasing wavelengths are achieved by exploiting the swelling properties of enzyme‐responsive hydrogel droplets in a Fabry–Pérot microcavity. Both experimental and theoretical means demonstrate that inner 3D network structures and external curvature of the hydrogel droplets lead to different lasing thresholds and resonance wavelengths. Finally, inkjet‐printed multiwavelength laser encoding and anti‐counterfeiting are showcased under different scalabilities and environments. Hyperspectral laser images are utilized as an advanced feature for a higher level of security. The biologically encoded laser will provide a new insight into the development of biosynthetic and bioprogrammable laser devices, offering new opportunities for secure communication and smart sensing.

Published: December 2021

AbstractThe engineering of a series of multienzyme‐mimicking covalent organic frameworks (COFs), COF‐909‐Cu, COF‐909‐Fe, and COF‐909‐Ni, as pyroptosis inducers, remodeling the tumor microenvironment to boost cancer immunotherapy, is reported. Mechanistic studies reveal that these COFs can serve as hydrogen peroxide (H2O2) homeostasis disruptors to elevate intracellular H2O2 levels, and they not only exhibit excellent superoxide dismutase (SOD)‐mimicking activity and convert superoxide radicals (O2•−) to H2O2 to facilitate H2O2 generation, but also possess outstanding glutathione peroxidase (GPx)‐mimicking activity and deplete glutathione (GSH) to alleviate the scavenging of H2O2. Meanwhile, the outstanding photothermal therapy properties of these COFs can accelerate the Fenton‐like ionization process to facilitate their chemodynamic therapy efficiency. One member, COF‐909‐Cu, can robustly induce gasdermin E (GSDME)‐dependent pyroptosis and remodel the tumor microenvironment to trigger durable antitumor immunity, thus promoting the response rate of αPD‐1 checkpoint blockade and successfully restraining tumor metastasis and recurrence.

Published: December 2021

AbstractLong‐lasting underwater superhydrophobicity involves stable‐in‐time air layer trapped and retained between a submersed surface and the overlying liquid. Due to its underwater nature, it is rather difficult to accurately observe this air layer in submerged systems, let alone to measure it. Here, white light reflectance spectroscopy is used for real‐time monitoring (acquisition speed 50–200 ms) of underwater superhydrophobicity as well as for the calculation of the entrapped air layer thickness on “everlasting” underwater polymeric superhydrophobic surfaces fabricated by plasma micro‐nanotexturing. The proposed method enables real‐time monitoring and accurate calculation of air layers with thicknesses ranging from a few nanometers to several tens of micrometers involving small underwater bubbles. In addition, different scale topographies of superhydrophobic plasma micro‐nanotextured surfaces are tested and found to retain underwater superhydrophobicity for at least 60 days. As a demonstration, the air layer thickness is also monitored in real time when titrating water with low surface tension liquids. Among several topographies tested, a superhydrophobic surface exhibiting hierarchical topography and a high roughness ratio is able to retain a stable air layer when submersed in liquids with surface tension down to 44 mN m−1.

AbstractIonic conduction of metal thiophosphates (MTPs) is attracting growing attention for promising applications in electrochemical storage and tunable physical properties. Especially, metal‐ion migration in copper thiophosphate has been identified as a key factor for the control of their microstructure and phase transition. However, direct evidence for the coupling between Cu‐ion motions and the crystal lattice has been elusive at the nanometer scale. Here, the room temperature diffusion kinetics of Cu ions in layered CuCrP2S6 (CCPS) is demonstrated. A tip‐enhanced electric field based on scanning probe microscopy (SPM) has been used as the driving force for Cu‐ion motions through van der Waals gaps. The strong coupling between Cu‐ion concentration and crystal lattice and the resulting serial structural transitions have been probed directly by the comprehensive utilization of spatially resolved Raman spectra, cross‐section energy dispersion spectrum (EDS), and high‐resolution transmission electron microscopy (HR‐TEM). This knowledge improves the understanding of the effect of intrinsic Cu‐ion migration on the structure transformation in layered van der Waals materials and provides feedback to the nanoscale mechanisms of nanometer devices based on iontronics.
Vertical Addressing of 1‐Plane Electrodes for Digital Microfluidics

Published: December 2021

AbstractDigital microfluidics (DMF) has become a mainstay in the microfluidics and microelectromechanical communities. Many users rely on simple DMF devices featuring a small number of rows and columns of electrodes that can be rapidly manufactured using “one plane” lithographic or printing techniques. But as the popularity of DMF grows, there are increasing needs for larger devices that can facilitate multiplexed handling of many samples and reagents in parallel. One option for scaling DMF devices is to use “vertical addressing” techniques such as printed circuit boards (PCBs), but PCBs formed using standard techniques exhibit topography that is not ideal for smooth and reliable droplet movement. A new method to produce DMF devices using vertical addressing of 1‐plane electrodes (VAPE‐DMF) is introduced. This method, which separates devices into “covers” (bearing 1‐plane electrodes) and “sub‐substrates” (for vertical addressing), enables rapid and inexpensive manufacture of devices with arbitrarily large driving electrode arrays. This work describes how to manufacture VAPE‐DMF devices and demonstrates a proof‐of‐concept device with an array of 336 electrodes to handle 48 droplets to run 24 reactions in parallel. It is proposed that VAPE‐DMF represents a useful new development for the growing community of users and innovators of digital microfluidics and related methods.

AbstractPaper‐based analytical devices, or μPADs, have proven to be valuable bioanalytical tools for a broad range of applications. New methods for μPAD fabrication are needed, however, to facilitate their mass production at a competitive cost. To address this need, the use of a boronic acid‐containing siloxane polymer (BorSilOx) has been reported for patterning hydrophobic barriers for μPADs. This material functions by covalently binding to hydroxyl groups in the paper substrate. It is compatible with inkjet printing or roll‐to‐roll (stamping) processes, as demonstrated here using three different deposition methods. BorSilOx is able to render a broad range of cellulosic materials (from paper towels to wood) hydrophobic, with contact angle measurements demonstrating superhydrophobicity in many cases.The utility of the polymer in μPADs via assays for pH and glucose is further demonstrated.
Near‐Field Mediated 40 nm In‐Volume Glass Fabrication by Femtosecond Laser

Published: December 2021

AbstractNanofabrication techniques have significantly impelled the development of nanomechanics and nanophotonics by making nano‐precision material processing routine. Although widely employed, current sub‐100 nm nanofabrication approaches based on focused particles or light are limited to surface modification. Here, an optical in‐volume fabrication approach that enables 3D glass processing with a spatial resolution down to 40 nm is demonstrated. Such an approach is based on the formation of a single nanoslit structure induced by femtosecond laser pulses. Spatially‐variant nanopatterns with uniform line‐widths are then formed by a near‐field mediated intensity redistribution of incident light. The redistribution of electromagnetic field induced by the presence of the nanoslit leads to a positive‐feedback self‐assembly process. The self‐assembly process allows achieving spacing one order of magnitude smaller than the laser beam size. In addition, a tilted ablation front that results in the generation of structures with curved morphology is revealed. The proposed approach enables 3D patterning with a lateral spacing down to 200 nm and 5D optical data storage with an equivalent capacity of 7.2 TB per disk, demonstrating its feasibility for 3D nanoscale processing in bulk materials.

Published: December 2021

AbstractStimuli‐responsive luminescent material‐based rewritable paper has received great attention for its potential application in a wide range of areas from anti‐counterfeiting to information encryption. Herein, a photoluminescence (PL) rewritable paper based on an organic metal halide, trans‐2,5‐dimethylpiperazine manganese(II) bromide (C6N2H16MnBr4) (1), is reported. This 0D organic metal halide hybrid exhibits green emission centered at 548 nm originating from 4T1–6A1 transition of tetrahedrally coordinated Mn2+ ions with a PL quantum efficiency of 82%. Interestingly, complex 1 can be transformed into the non‐emissive hydrated phase C6N2H16MnBr4(H2O)2 (2) by uptake of coordinating water molecules, wherein Mn2+ adopts a quasi‐octahedral coordination sphere. The reversible single‐crystal structure transformation between the hydrated and dehydrated phases can switch the PL on and off. Rewritable PL paper has been fabricated by coating complex 1 on filter paper, which exhibits high resolution and excellent “write‐erase‐write” cycle capability. This work presents a new avenue for low‐dimensional lead‐free organic metal halide hybrids toward multilevel information security applications.
