Increased energy consumption, driven by climate change and the rise of new industries, has spurred a demand for alternative cooling technologies to replace energy‐intensive systems and mitigate environmental pollution. Radiative cooling, leveraging the optical properties of materials to cool without emitting pollutants or consuming energy, is considered a suitable solution. Among the various form of radiative cooling devices, paint stands out as a practical application for radiative cooling. Hence, a passive daytime radiative cooling (PDRC) paint is developed using a polyurethane binder and zeolitic imidazolate framework (ZIF)‐8. ZIF‐8 is synthesized in an environmentally friendly manner using deionized water as the solvent, resulting in paint with a reflectance of 94.9%, emissivity of 94%, and cooling power of 113 W m−2. Temperature measurements reveal that the paint reduced ambient temperatures by an average of 5.7 °C, reaching up to 8.1 °C during the day. Additionally, with a self‐assembly monolayer coating, the PDRC surface exhibited super‐hydrophobicity and self‐cleaning capabilities. Therefore, the proposed ZIF‐8‐based PDRC paint offers sub‐room temperature cooling potential and is anticipated to reduce energy consumption for cooling, thereby alleviating environmental pollution in various applications, particularly in building exteriors.

Dynamic binary instrumentation (DBI) is a technique that enables the monitoring and analysis of software, providing enhanced performance compared to other analysis tools. However, to provide the robust dynamic analysis capabilities, it commonly requires the setup of separate environments for analysis, thereby increasing the contrast with normal execution and the distinctive features that may reveal the presence of the DBI environment. Malware adapts to detect the presence of DBI environments, and it consequently leads to the expansion of the attack surface. In this paper, we provide an in-depth exploration of anti-instrumentation techniques that can be exploited by malware, with a specific focus on the Windows operating system. Leveraging the unique features of the DBI environment, we introduce and categorize DBI detection techniques. Additionally, we conduct a comprehensive analysis of the techniques through the implementation algorithms with bypassing methods for the techniques. Our experiments showcase the effectiveness of these techniques on the latest versions of several DBI frameworks. Furthermore, we address associated concerns with the aim of contributing to the development of enhanced tools to combat malicious activities exploiting DBI and propose directions for future research.

Oxynitride blue-green-emission BaSi2O2N2:Eu2+ phosphors were synthesized at 1400°C under a reducing ambient through a solid-sate reaction method. They showed the blue-green emission peaking at 490-500 nm and narrow width (~32 nm) along with varying concentrations of from 2 to 10 mol %. It is due to 4f-5d transition from Eu2+. XRD pattern showed a single phase of BaSi2O2N2 structure. This enables silicon-based BaSi2O2N2:Eu2+ phosphors to be excited efficiently by UV or blue-light irradiation, and then be applied as down-conversion luminescent materials in white LEDs the class of oxynitride phosphors has demonstrated its superior suitability white LED can be used in bichromatic or multichromatic LEDs with excellent properties of high luminous efficiency, high chromatic stability, a wide range of white light with adjustable Correlated Color Temperature (CCT), and high color-rendering properties [1]. A blue-green BaSi2O2N2:Eu2+ phosphors obtained high color rendering and high-efficiency white LEDs (Ra 90, 70 lm/W). [ABSTRACT FROM AUTHOR]

The K2SiF6:Mn4+ phosphor was synthesized by a redox reaction from SiO2 [1]. Under the 450 nm excitation, K2SiF6:Mn4+ show a narrow deep-red emitting around 633 nm which attributed to the 2Eg to 4A2g transition of Mn4+ ion with the half width of 8 -10 nm. The particle size was approximately 8 μm. We obtained single phase of cubic structure with a space group of Fm-3m (225) which agree with XRD pattern of JCPDS # 85-1382. In the temperature dependence of emission spectra, emission intensity decrease to around 60 % (80%@200°C YAG) of that at room temperature is about 175°C. The chemical stability of the phosphors was improved by coating the phosphor with target metal oxide. These phosphors can be efficiently excited by the blue light-emitting InGaN diode and provides a high color rendering property with green or yellow phosphors. It will be useful as a red phosphor for white-light-emitting diode. [ABSTRACT FROM AUTHOR]
