Calcium silicate hydrate decorated by Fe, Ti co-modified birnessite direct multi-component photocatalyst: Design, preparation and photocatalytic performance under visible light irradiation

Constructing a multi-component structure is an effective strategy to promote the formation of oxygen vacancies (OVs), which can enhance electron transition to improve the photocatalytic activity of materials. In this work, it was designed a series of novel photocatalysts supported on calcium silicate hydrates (C-S-H) via density functional theory calculation. These designed photocatalysts were then synthesized and marked as Bir@C-S-H, TiO2/Bir@C-S-H, and α-Fe2O3/TiO2/Bir@C-S-H, respectively. In comparison to other catalysts, α-Fe2O3/TiO2/Bir@C-S-H photocatalyst has a higher specific surface area, a lower band gap, more OVs, which can activate more dioxygen molecules, and more reactive radicals. The photocatalytic activity of as-synthesized photocatalysts was verified by using HCHO as the target pollutant. To the treatment of 80 ppm HCHO, the α-Fe2O3/TiO2/Bir@C-S-H exhibits 100% HCHO conversion corresponding gas hourly space velocity of 60 L/(g•h) with a relative humidity of 60% under visible light irradiation, while Bir@C-S-H and TiO2/Bir@C-S-H present 89.92% and 94.17% HCHO conversion, respectively at same conditions. This work demonstrates a more effective calcium silicate hydrate decorated by Fe, Ti co-modified birnessite heterostructures for HCHO oxidation, which can be directly used as decorative materials, providing a novel guidance for practical application.

Research Progress on the Improvement of Flame Retardancy, Hydrophobicity, and Antibacterial Properties of Wood Surfaces

Wood-based materials are multifunctional green and environmentally friendly natural construction materials, and are widely used in decorative building materials. For this reason, a lot of research has been carried out to develop new and innovative wood surface improvements and make wood more appealing through features such as fire-retardancy, hydrophobicity, and antibacterial properties. To improve the performance of wood, more and more attention is being paid to the functioning of the surface. Understanding and mastering technology to improve the surface functionality of wood opens up new possibilities for developing multifunctional and high-performance materials. Examples of these techniques are ion crosslinking modification and coating modification. Researchers have been trying to make wooden surfaces more practical for the past century. This study has gradually gained popularity in the field of wood material science over the last 10 years. This paper provides an experimental reference for research on wood surface functionalization and summarizes the most current advancements in hydrophobic, antibacterial, and flame-retardant research on wood surfaces.

The contribution of archeometry in characterization of decorative materials from the site of Villa di Teodorico in Galeata (Italy)

Villa di Teodorico in Galeata (Forlì-Cesena, Emilia Romagna) is an important archeological site in the north of Italy occupied from sixth century BC to twelfth century AD. The most interesting results concern the Roman age, when a large villa was built, and the late antiquity, when the Ostrogothic king Theodoric decided to build in this area his palatium (early sixth century AD). The archeometric investigation was performed on Roman wall paintings fragments and on late antique glass sectilia fragments belonging to Palazzo di Teodorico by using a multi-technique approach that included micro-Raman spectroscopy, scanning electron microscopy with energy-dispersive spectroscopy, X-ray powder diffraction, UV–visible–NIR diffuse reflectance spectrophotometry with optic fibers and optical stereo-microscopy.. This analytical approach allowed the identification of all components, collecting molecular, elemental, microscopic, morphological and chromatic data. The characterization of samples supplied essential archeological, historical and technological information. The production techniques and the rich materials employed suggest the importance of the site in different periods. The evolution of the manufacturing technologies and the possible trade routes mainly during late antique period are witnessed by the change in the raw materials.Graphical abstract

Preparation and Properties of Hydrophobic and Oleophobic Coating for Inkjet Printing

As a functional decorative material on the surface of printing and packaging, coating plays the role of increasing gloss, wear resistance, and antifouling. It has broad application prospects in high-end printed materials such as posters, art reproductions, and maps. In this paper, dodecafluoroheptyl methacrylate was used as the fluorine-containing monomer, which was used to modify the epoxy resin and introduce fluoride first. Under the action of polymerization inhibitor and catalyst, the epoxy resin was further modified by ring opening, esterification, and neutralization with acrylic acid, maleic anhydride, and organic base as raw materials. Additionally, a fluorine-containing coating with hydrophobic and oleophobic properties was obtained finally. The effects of fluorine modification of epoxy resin and synthetic polymer were characterized by infrared spectrometer and photoelectron spectroscopy. The results showed that fluorine monomer could be successfully grafted to the molecular body of epoxy resin, and fluorine had been introduced into the surface of the polymer film. Using the contact angle tester, combined with the performance parameters such as grafting rate, thermal stability, adhesion, and gloss, the effects of the amount of fluorine monomer on the properties of the synthetic coating were discussed. The results showed that the hydrophobic and oleophobic properties of the copolymer film surface were closely related to the amount of fluorine monomer. When the molar ratio of the epoxy group to dodecafluoroheptyl methacrylate was 26:1, the mass fraction of fluorine on the film surface was 18.09%, and the contact angles of water and ethylene glycol were 121.8° and 78.2° respectively. At the same time, the printability of self-made hydrophobic and oleophobic coating was tested in this paper. The liquid repellency of inkjet printing before and after glazing and the influence of the coating on the optical properties of printed images were discussed and studied too. The results showed that the coating synthesized by the experiment was suitable for inkjet printing. It had improved the printing quality performance and the functional modification on the surface of inkjet printings, such as liquid repellency, gloss, and color reproduction.

Hydroquinone triggers pyroptosis and endoplasmic reticulum stress via AhR-regulated oxidative stress in human lymphocytes

Benzene is a frequent component of environmental pollution and is abundant in petrochemicals, decorative materials, motor vehicle exhaust and cigarette smoke. Benzene is a well-known carcinogen in humans and animals, but the molecular mechanism has not yet been elucidated. Our earlier research indicated that hydroquinone (HQ), one of the main reactive metabolites of benzene, could activate aryl hydrocarbon receptor (AhR), which is essential for HQ-induced toxicity, including apoptosis and DNA damage. Since AhR is an important regulator of the immune system that integrates the environmental stimulus and immune response, we examined whether and how HQ-induced AhR activity could lead to NLRP3 inflammasome-dependent pyroptosis in JHP cells. Our results showed that HQ could cause inflammation process and resultant pyroptosis. In JHP cells, HQ also induced endoplasmic reticulum stress (ERS) by releasing excessive reactive oxygen species (ROS). The activation of pyroptosis induced by HQ treatment was reversed by an antioxidant (NAC) and an ERS inhibitor (4-PBA). Interestingly, the treatment of CH223191, an AhR inhibitor, reversed HQ-induced oxidative stress, ERS and pyroptosis. These data suggested that AhR-mediated HQ-induced ERS, ROS and inflammasome activation may play vital roles in the toxic effects of benzene. This work provides insights and prospective strategies into potential mechanisms for reducing benzene-induced hematotoxicity.

Research on Decorative Materials Properties Used in the Production of Cabinets Based on Visual/Tactile Experience

With the further deepening of ageing in China, the ageing-in-place model is gaining more and more attention. In order to improve the quality of home life of the elderly, this paper takes age-friendly cabinets as the research object, from the perspective of material design, and takes the visual/tactile experience of the elderly as the entry point, classifies the current market cabinet materials, and selects the test samples. The physical properties of the samples were examined and analysed with the subjective emotional changes that the elderly experience with different cabinet materials. The objective physical properties of the cabinet materials were correlated with the visual/tactile subjective emotional factors, and through subjective tests and mathematical and statistical methods, an evaluation model of “visual/tactile subjective emotional factors—objective physical properties of materials” was established for the selection of materials in age-friendly cabinet design. It provides scientific guidance for the selection of materials in age-appropriate cabinet design.

Improving mechanical/colorimetric properties of self-compacting mortar using an intensively colored-nanoparticle containing polymeric paste

Colored self-compacting mortars (C-SCMs) are important decorative materials for construction and building industries. It has been found that using inorganic/organic pigments for coloring the SCMs causes considerable decrement in the mechanical and aesthetic properties. In the last decade, latex modified C-SCMs were developed that showed improved color properties with lower effects on the mechanical properties. In present work, high performance-water based colored pastes were prepared using SBR latex (as binder), phthalocyanine blue (as organic pigment at 1.5 and 3 wt%) and CaCO3 nanoparticles (as reinforcement). The pre-fabricated pastes were added to a SCM mix design as coloring agent. The prepared samples were evaluated for colorimetric (i.e. L*, C* and H*) and mechanical (i.e. compressive and flexural) properties. For comparison, the organic pigment (at 0.25, 0.5, 0.75 and 1.5 wt%) and SBR latex (at 5 wt%) were also used to prepare latex modified C-SCM samples. The results showed that addition of 3 wt% of CaCO3 nanoparticles to the pre-fabricated colored paste caused improvement in the flexural strengths (by 28%) and flexural toughness (by 86%) of the prepared mortars compared to the latex modified C-SCM. Despite of using an organic pigment, the colorimetric properties (i.e. color difference and uniformity) and the pigment saturation point (by 100%) of the prepared C-SCMs were also improved using the nano-based coloring pastes.

Surface modification study of CaO-Al2O3-SiO2-Fe2O3 base system high temperature phase reconstruction

The fly ash was used as raw material to prepare glass ceramic base body, on which a layer of glaze slurry was applied, then, the complex was successfully prepared by sintering at 1180 °C through single-sinter process. Influences of quartz sand content on crystal phase evolution, physical–mechanical properties, and surface morphology of products were studied systematically. Finally, an opaque glaze with 15 wt% quartz sand fitting on glass ceramic base body had been produced, exhibiting a unique main phase, mullite, which ensured a significant Vickers microhardness of 8.1 GPa, improving the mechanical properties of solid waste glass ceramic base body. It was also found that the water absorption of the product was .66%, which greatly enhanced the waterproof function of the base surface. The complex products developed in this study were expected to be used as building decoration materials and provided new ideas for effective reuse of other similar solid wastes.

A facile green and cost-effective manufacturing process from coal gangue-reinforced composites

Utilization of high-filler coal gangue (CG) to produce cost-effective composites is a promising strategy. To clarify the impact of high-filled CG on composite preparation and performance, in this research, the composite was prepared from CG and polyethylene (PE) through physical mixing and then hot-pressing. The role of CG in the properties of the composites and the influence of the interface formation mechanism are obtained by establishing the relationship between CG content and the composites' feature. The results show that: high-filler CG is helpful to the increment of the composite's mechanical and thermostable properties. When the CG addition is up to 80%, the density and hardness from 0.93 g/cm3 and 50.5 HD increased to 1.60 g/cm3 and 66.5HD, which was increased by 72.0% and 31.6%, respectively. Meanwhile, the bending strength and modulus reach 17.5 MPa and 3400.6 MPa, which is respectively exceeded by 56.3% and 628.6% than composite from pure PE (11.2 MP and 466.7 MPa). In addition, high-filler CG is beneficial for the enhancement of entanglement between CG and PE during the composite preparation, and has the effect of heterogeneous nucleation, which facilitated the crystallization and thermal stability of the composite. The properties of the composites prepared by this simple technique meet national standards and are more economical and environmentally sustainable than composites prepared with other fillers. This new material holds great promise for the development and realisation of carbon-neutral decorative materials such as assembly buildings, vehicles and coloured panels.

Acoustic Quality of Volcanic Rock Material for Interior Space Control and Design: Evidence from Teaching Space

A good school environment means that the campus environment formed by school buildings shows perfect overall characteristics and that various facilities included in the planning and design meet or surpass the demands of users in their education, living, and studying aspects. In this study, the learning space is taken as the research object to discuss the design method and value of using volcanic rock as a wall decoration material in space by carrying out sound test research on the volcanic rock material in the room. A sound field experiment was conducted based on the characteristics and principles of sound propagation in space combined with the design status quo of the teaching space and the acoustic environment in ordinary colleges and universities. Thus, the sound absorption effects of the volcanic rock used as the decoration material in teaching space and its advantages in this field were studied. The study results show that using volcanic rock in spatial design leads to better sound absorption effects than using other materials. In the future, it can be applied as an interior decoration material in spaces requiring acoustic control.

Litracon: An alternative source for conventional concrete

The consumption of artificial light, especially in urban areas, leads to global warming. As a remedy this light transmitting concrete acts as a solution for global warming. Light transmitting concrete is made with cement ,water , very fine sand and thousands of optical fibres reinforced in concrete from one face to another face which guide the light passing through it. Light transmitting concrete is a concrete that is improved in terms of transparency by installing optical fibres into concrete. We used 3% of optical fibre in this concrete. Due to its pellucidity property, it is also called translucent concrete. The application of light transmitting concrete which allows light to transmit through non-transparent concrete reduces energy in closed environments and global warming. Translucent concrete is used in fine architecture as a decorative material. It has all these properties which an eco-friendly technique should have to keep up the green building concept into consideration. The present investigation about the light translucent concrete by using optical fibre and comparing it with conventional concrete. Compressive strength test is performed on the concrete specimen. Utilising 3% more optical fibres enhanced the compressive strength. compressive strength of concrete cube depends on the diameter of the holes in the mold & the diameter of the optical fibre. It is directly proportional to its compressive strength.

Robust and facile detection of formaldehyde through transition metals doped olympicene sensors: a step forward DFT investigation.

Formaldehyde, a volatile organic compound (VOC) released by building and decoration materials, has many applications in the chemical feedstock industry. Excessive release of formaldehyde can cause serious health issues, such as chest tightness, cough, cancer, and tissue damage. Therefore, detection of formaldehyde is required. Herein transition metal (Fe, Ni, and Pd) doped olympicene is evaluated as a gas sensor for the detection of formaldehyde. The performance of the designed electrochemical sensor is evaluated through interaction energy, natural bond orbital (NBO) non-covalent interaction (NCI), electron density differences (EDD), electrostatic potential (ESP), quantum theory of atom in molecule (QTAIM), frontier molecular orbital (FMO), and density of states (DOS) analysis. Interaction energies obtained at B3LYP-D3/def-2 TZVP level of theory shows that formaldehyde is physiosorbed over the surface of transition metal doped olympicene. The trend for interaction energy is OLY(Ni)/HCHO > OLY(Fe)/HCHO > OLY(Pd)/HCHO. The presence of non-covalent interactions is confirmed by the QTAIM and NCI analyses, while transfer of charges is confirmed by natural bond orbital analysis. The reduced density gradient (RDG) approach using noncovalent interaction (NCI) analysis demonstrates that electrostatic hydrogen bonding interactions prevail in the complexes. Recovery time is calculated to check the reusability of the sensor. This study may provide a deep insight for the designing of highly efficient electrochemical sensor against formaldehyde with transition metals doped on olympicene.

Janus metallic film with gold and silver luster by electroless deposition of silver using poly(dopamine acrylamide) thin film.

Films that exhibit different metallic luster on the front and back, called Janus metallic films, have broad applications ranging from design materials to optical devices. However, the fabrication of these films is often a complicated process involving multiple metal deposition steps, thermal annealing, and calcination. Herein, we report the simple preparation of a Janus metallic film by electroless deposition of silver on a poly(dopamine acrylamide) (pDOPAm) thin film. pDOPAm was successfully synthesized via the controlled reversible addition-fragmentation chain transfer polymerization of dopamine acrylamide without a protective group using dimethylformamide as the solvent. The synthesized pDOPAm was spin-coated onto a solid substrate, which was then immersed in an aqueous AgNO3 solution to achieve the electroless deposition of silver. Our preparation method will considerably simplify the fabrication of Janus metallic films, enabling their widespread application as decorative or authentication materials.

Self-healing and adaptive concrete material

Over the last several decades, there has been a surge in interest in studying smart materials and their applications in various sectors, particularly building technology and architecture. Although smart materials are not new, researchers are working to construct smart materials and a system to regulate the materials to produce a living environment with fewer negative effects and greater adaptive capabilities. To investigate the excellent performance of architectural decorative materials in the fields of technology and art throughout specific historical periods, the research aims to evaluate the properties and architectural benefits of smart material systems and further analyze their impact on the construction process. In addition to exploring new ways to develop architecture with more vital adaptive traits, to reach the condition of “adaptiveness,” creating an optimum experience for consumers and concentrating on architectural, structural, and climatic efficiency go hand-in-hand with the Saudi Vision 2030. Concrete is well known for its low cost, wide availability, and simple usage, making it the most extensively consumed material. However, it has weaknesses that include unpredictable cracking behavior that leads to poor structural performance, which could – later on – decrease the life expectancy of the building. Hence, using smart substances that could neutralize the cracking tendencies is the optimal choice when considering the world at its current track.
