The water states and distribution in frozen dough are critical to its quality. In this study, variable temperature 1H time-domain nuclear magnetic resonance (VT-NMr) was used to in situ investigate the unfrozen water (UFW) content of frozen dough and the changes in water distribution during the freezing process. VT-NMr results indicated that higher gluten content and lower water content corresponded to higher UFW levels. The UFW content measured by VT-NMr was consistent with values obtained by differential scanning calorimetry (dSC), confirming the efficacy of VT-NMr as a non-destructive tool for studying water states in frozen dough. during the freezing process from 2 °C to -30 °C, both the water proton population area and T2 relaxation time decreased significantly. At -30 °C, the water distribution within the dough stabilized. VT-NMr offered significant potential for online quality monitoring in industrial frozen dough production. © 2025, The Authors.

The thermal expansion property of epoxy mortar has a significant effect on the repair effect. Experiments were carried out to study the thermal expansion coefficient of epoxy mortar by changing the type of curing agent, various sand binder ratios and sand etc. The results show that the curing agent has a remarkable effect on the thermal expansion coefficient of epoxy mortar. When the type and content of curing agent are fixed, the influence of sand binder ratio and sand type on thermal expansion coefficient of epoxy mortar is relatively small. It is an effective way to reduce the thermal expansion coefficient of epoxy mortar with excellent curing agent. The research conclusion can provide a reliable basis for hydraulic concrete repairing. © 2021 IOP Conference Series: Earth and Environmental Science.

A geomimetic, ultrafast, and one-step preparation method for an N-doped reduced TiO2porous layer using the atmospheric plasma spraying (APS) technique is proposed. The secondary gas provided by the APS (H2) is responsible for reducing TiO2, while an acetamide solution stored in the pores of the substrate acted as a nitrogen source for TiO2doping. Inspired by the nature of volcanic eruptions on Earth, we used a geomimetic vapor-induced pore-forming (VI-PF) mechanism to produce porous N-doped TiO2via one-step preparation. We varied the acetamide solution concentration to synthesize different samples (TNX,Xindicates the wt % of acetamide solution) to approach photocatalytic tetracycline (TC, 20 ppm/100 mL) degradation under AM1.5G solar simulator irradiation. When the acetamide solution concentration was 5 wt %, the sample (TN5) showed the highest lattice-nitrogen content, which gave it the highest photocatalytic degradation efficiency (rate constant = 1.71 × 10–2min–1) of TC. Moreover, after 15 rounds of recycling tests, the removal rate and crystalline structure remained stable. In addition to experiments, density functional theory (dFT) calculations are also used to verify the experimental results, and they are also consistent with each other. This work is the first study using the APS technique in a single-step process for nitrogen doping and H2reduction and is a green, cost-effective, time-saving, and promising method for the mass production of porous TiO2.

A series of novel EGFr inhibitors were designed and synthesized based on the scaffold of osimertinib, the inhibitory activities against the L858r/T790M/C797S mutant EGFr kinase of which were subsequently evaluated. Compounds with the imine fragments showed the highest kinase inhibitory activity and were proved to be reversible inhibitors, which were represented by the compound dd-8 (IC50 = 0.87 nM). Kinase selectivity assay showed the compounds with imine fragments were preferred to inhibit the triple-mutant EGFr kinases rather than other subtypes. In the proliferation inhibition assay against the BaF3-EGFr(L858r/T790M/C797S) cell line, the compound dd-8 also showed strong inhibitory activity (IC50 = 1.11 μM), and the inhibition rate of which reached 98.8% at the concentration of 2 μM. To further elucidate the antitumor mechanism of the compound dd-8, a comprehensive series of experiments were conducted, including apoptosis induction assay, cell cycle arrest assay, Western blot assay, cell migration inhibition assay, liver microsomal stability experiment, and molecular docking analysis. © 2025, The Authors.

Construction of transfer-free regular through-pore polyimide composite microfiltration membranes via amphiphilic dendron-assisted breath-figure method for water treatment

regular through-pore membranes exhibit extremely high productivity and size-selective capabilities. Previous studies have demonstrated that the use of a polymer alone on a solid substrate surface hinders the formation of regular through-pore membranes. In this study, amphiphilic dendrons were used as surfactants to concentrate the functional groups and strengthen the weak bonding forces between the molecules, which is conducive to the formation of regular through-pores in the membrane. The amphiphilic dendrons were mixed with commercial-grade polyimide (PI) using chloroform as the solvent, and the solution was evenly coated on the surface of the filter paper. Using the breath-figure method, an ultrathin regular through-pore PI layer was formed directly on the surface of the filter paper. The SEM image shows that regular through-pores were formed only on the surface of the substrate. The preparation process used in this study eliminates the need to transfer ultrathin and weak membranes to the substrate surface, which simplifies the membrane-making process. Pure water and yeast solution filtration tests were conducted on the composite membrane prepared with a 5 mg/ml dendron solution. A pure water permeance of 118,826 L m-2h−1 bar−1 (LMH/bar) was obtained, the yeast solution permeance and rejection are 17,410 LMH/bar and 92.85 %, respectively. The yellow, turbid, muddy water was successfully purified to clean water. The original performance of the fouled membrane was restored after only 30 s of water flushing. This study proposes a new approach to fabricate high-efficiency regular through-pore PI composite microfiltration membranes. © 2023 Elsevier B.V.

Many models combining Transformers with convolutional neural networks (CNNs) for computer vision tasks have achieved state-of-the-art results. However, due to the different computation patterns between attention and convolution, using a dedicated Transformer or CNN accelerator will inevitably reduce the computing efficiency of the other. To overcome this problem, we propose a unified architecture for attention and convolution on FPGA. We reduce runtime overhead by offloading part of self-attention computations offline before inference. Furthermore, we present a unified mapping method according to the computing characteristics of attention-based and convolution-based models. This accelerator implements multi-head attention in Transformer, independent resNet-50 and hybrid blocks of attention and con-volution in BoTNet-50 at 200MHz on Xilinx Virtex Ultrascale+ XCVU37P. Experimental results show that the solution is nearly 3.62 times more energy-efficient than the NVIdIA V100 GPU, and the computational efficiency is 11.86% and 28.29% higher than the state-of-the-art Transformer and resNet-50 accelerators, respectively.

Here, we demonstrate world’s first 1 Hz driving fringe-field switching (FFS) LCd via development of low flexoelectric coefficient LCs with high voltage holding ratio (VHr). The evaluation of the 1 Hz driving 13.4-inch FFS LCd laptop panel shows no flicker, and the power consumption is reduced by 83% compared to the 60 Hz driving. We believe this result opens a new chapter of FFS LCds for low-power consumption. © 2023, John Wiley and Sons Inc. All rights reserved.
