Biomaterials-based phototherapy for bacterial infections.

Bacterial infections and antibiotic resistance are global health problems, and current treatments for bacterial infections still rely on the use of antibiotics. Phototherapy based on the use of a photosensitizer has high efficiency, a broad spectrum, strong selectivity, does not easily induce drug resistance, and is expected to become an effective strategy for the treatment of bacterial infections, particularly drug-resistant infections. This article reviews antimicrobial strategies of phototherapy based on photosensitizers, including photodynamic therapy (PDT), photothermal therapy (PTT), and their combination.

Buried PE Pipeline Location Method Based on Double-Tree Complex Wavelet Cross-Correlation Delay.

This study presents a location method for buried polyethylene (PE) pipelines based on the double-tree complex wavelet cross-correlation delay. Initially, the dual-tree complex wavelet transform (DTCWT) is applied to denoise the acquired signal, followed by extracting the delay time through the cross-correlation function to locate the buried pipeline. A simulation model is established to analyze the peak values of the time-domain signals in both asymmetric and symmetric sensor layouts using COMSOL, determining the relationship between the signal time differences and pipeline positions.

A Metasurface Glass for Energy Saving and 5G Mobile Communication Signal Enhancement.

Windows constitute a significant portion of the facade in buildings and modern ground transportation vehicles, such as commercial skyscrapers, high-speed trains, and subway systems. Traditional glass windows lack adequate thermal insulation and heat retention capabilities; Low-Emissivity (Low-E) glass can block external infrared radiation, it also impedes mobile communication signals, particularly those in the 5G Sub6G frequency band. This paper introduces an innovative metasurface glass designed to enhance 5G mobile communication signals within the interior of glass windows.

Transport characteristics and dispersion evolution of CO-NOx mixture exhaust for shuttle movement emission in short-wall continuous mining face.

To investigate the evolution of CO and NOx pollution in the exhaust gas from diesel-powered shuttles under the double lane ventilation system of short-walled continuous mining face, this article uses a combination of numerical simulation and field tests to numerically simulate and analyze the pollution transport law of CO and NOx emitted from the shuttles at three locations: heading tunnel, contact alley and supporting tunnel. The results show that when the shuttle car in heading tunnel, the CO and NOx discharged from the shuttle discharge port move toward the exit of the tunnel at an average speed of 1.25 m/s.

Integrated Artificial Neural Network with Trainable Activation Function Enabled by Topological Insulator-Based Spin-Orbit Torque Devices.

Nonvolatile memristors offer a salient platform for artificial neural network (ANN), yet the integration of different function and algorithm blocks into one hardware system remains challenging. Here we demonstrate the brain-like synaptic (SOT-S) and neuronal (SOT-N) functions in the BiTe/CrTe heterostructure-based spin-orbit torque (SOT) device. The SOT-S unit exhibits highly linear and symmetrical long-term potentiation/depression process, resulting in a fast-training of the MNIST data set with the classification accuracy above 90%.

[Preparation, characterization and antitumor effect of iron-based organic framework nano preparations loaded with piperlongumine].

The preparation processes of iron-based organic framework(FeMOF) MIL-100(Fe) and MIL-101(Fe) with two different ligands were optimized and screened, and the optimized FeMOF was loaded with piperlongumine(PL) to enhance the biocompatibility and antitumor efficacy of PL.

2D Metal Enabled Weak Fermi Level Pinning Effect and Tunable Charge Injection in Contacts with Inorganic 2D Perovskites.

Tow-dimensional (2D) perovskites have invoked extensive interest because of their good stability and intriguing optoelectronic properties. However, in practical applications, the hampered carrier transportation imposed by the vertical array of large dielectric organic cations and the generally seen Fermi level pinning (FLP) effect in conventional metal-2D semiconductors need to be solved urgently.

Potential roles of UCH family deubiquitinases in tumorigenesis and chemical inhibitors developed against them.

Deubiquitinating enzymes (DUBs) are a large group of proteases that reverse ubiquitination process and maintain protein homeostasis. The DUBs have been classified into seven subfamilies according to their primary sequence and structural similarity. As a small subfamily of DUBs, the ubiquitin C-terminal hydrolases (UCHs) subfamily only contains four members including UCHL1, UCHL3, UCHL5, and BRCA1-associated protein-1 (BAP1).
