Heat transfer properties of the numerical human body simulated from the thermal manikin

This paper seeks to predict the heat transfer properties of the numerical manikin. It also aims to establish a simplified clothing model based on computational fluid dynamics (CFD) to predict the temperature in air layers between thermal manikin and clothing under different environments. The field experiments of naked or clothed thermal manikin were conducted in a climatic chamber. The CFD method was employed to build a naked or clothed numerical manikin to simulate the field experiment. The distribution of temperature and the velocity field around the naked human body and heat transfer coefficients was simulated in the optimized numerical climate chamber with a temperature of 20°C and velocity of 0.05?m/s. The temperature in air layers entrapped in clothing on the torso of manikin was also predicted under the same environmental condition. The CFD results showed good agreement with that of the naked or the dressed thermal manikin experiment. It demonstrated that CFD could properly predict the heat transfer properties of indoor human and temperature distribution in the air layer between human body and clothing.

Antibodies@MOFs: An In Vitro Protective Coating for Preparation and Storage of Biopharmaceuticals

Antibodies have emerged as a fast‐growing category of biopharmaceuticals that have been widely applied in scientific research, medical diagnosis, and disease treatment. However, many antibodies and other biopharmaceuticals display inferior biophysical properties, such as low stability and a propensity to undergo aggregation. Enhancing the stability of biopharmaceuticals is essential for their wide applications. Here, a facile in vitro protective coating strategy based on metal–organic frameworks (MOFs) is proposed to efficiently protect antibodies against perturbation environments and quickly recover them from the MOFs before usage, which avoids introducing protective additives into the body, which may cause biosafety risks. The protected antibodies exhibit extraordinary thermal, chemical, and mechanical stabilities, and they can survive for long‐term storage (>3 weeks) under severe temperature variation (4 ? 50 °C) at a fast ramp rate (25 °C min^?1). More importantly, the encapsulated antibodies can be easily released as quickly as 10 s with high efficiency (≈100%) to completely remove the MOFs before use. This study paves a new avenue for the facile preparation and storage of biopharmaceuticals represented by antibodies under ambient or perturbation conditions, which may greatly broaden and promote the applications of both MOFs and biopharmaceuticals.     

2D Layered Graphene Oxide Films Integrated with Micro‐Ring Resonators for Enhanced Nonlinear Optics

Layered 2D graphene oxide (GO) films are integrated with micro‐ring resonators (MRRs) to experimentally demonstrate enhanced nonlinear optics. Both uniformly coated (1?5 layers) and patterned (10?50 layers) GO films are integrated on complementary‐metal‐oxide‐semiconductor (CMOS)‐compatible doped silica MRRs using a large‐area, transfer‐free, layer‐by‐layer GO coating method with precise control of the film thickness. The patterned devices further employ photolithography and lift‐off processes to enable precise control of the film placement and coating length. Four‐wave‐mixing (FWM) measurements for different pump powers and resonant wavelengths show a significant improvement in efficiency of ≈7.6 dB for a uniformly coated device with 1 GO layer and ≈10.3 dB for a patterned device with 50 GO layers. The measurements agree well with theory, with the enhancement in FWM efficiency resulting from the high Kerr nonlinearity and low loss of the GO films combined with the strong light–matter interaction within the MRRs. The dependence of GO's third‐order nonlinearity on layer number and pump power is also extracted from the FWM measurements, revealing interesting physical insights about the evolution of the GO films from 2D monolayers to quasi bulk‐like behavior. These results confirm the high nonlinear optical performance of integrated photonic resonators incorporated with 2D layered GO films.
