Enhance Heart Rate Measurement from Remote PPG with Head Motion Awareness from Image.

Measurement of cardiac pulse rate through image-based remote photoplethysmography (rPPG) is drawing attention to applications of continuous health monitoring. Meanwhile, extracting clean rPPG signals and reliable heart rate (HR) remotely is challenging especially in real-life scenarios where users can move freely. In this paper, we leverage head motion information in the video to increase tolerance of vital estimation against the motion.

Metal-Modified Zr-MOFs with AIE Ligands for Boosting CO Adsorption and Photoreduction.

The design and synthesis of metal-organic frameworks (MOFs) with outstanding light-harvesting and photoexcitation for artificial photocatalytic CO reduction is an attractive but challenging task. In this work, a novel aggregation-induced emission (AIE)-active ligand, tetraphenylpyrazine (PTTBPC) is proposed and utilized for the first time to construct a Zr-MOF photocatalyst via coordination with stable Zr-oxo clusters. Zr-MOF is featured by a scu topology with a two-fold interpenetrated framework, wherein the PTTBPC ligands enable strong light-harvesting and photoexcitation, while the Zr-oxo clusters facilitate CO adsorption and activation, as well as offer potential sites for further metal modification.

Semiconductive Coordination Polymer with Multi-Channel Charge Transfer for High-Performance Direct X-ray Detection.

Coordination polymers (CPs) are promising for direct X-ray detection and imaging owing to higher designability and outstanding stability, however, it remains a challenge to achieve highly X-ray detection performance, particularly both high sensitivity and low detection limit at the same operating voltage. Herein, we construct a new conjugated CP {[Co(BPTTz)(DIPA)] ⋅ DMA} (1, BPTTz=2,5-bis(pyridine-4-yl)thiazolo[5,4-d]thiazole, HDIPA=2,5-diiodoterephthalic acid, DMA=N, N'-dimethylacetamide), with multi-channel charge transfer by regulating the linker mediated electronic-state, which reduces carrier losses resulting from recombination or quenching, enhances the efficiency of charge separation and transfer, thus further optimizes X-ray detection performance. The semiconductor prepared based on this strategy achieves record values including the highest mobility-lifetime product (μτ, 8.

Self-cascade catalytic system constructed using carbon dots and Au nanoparticles co-assembled on MIL-53(Fe)-NH as a three-in-one fluorescent nanozyme for multimodal detection of glucose and maltose in food.

Confinement Microenvironment Regulation of Carbon Dots in Zeolite for Multi-Mode Time-Dependent Phosphorescence Color Evolution.

Matrix immobilization has been proven to be a favored method for enhancing the phosphorescence of carbon dots (CDs), however, it remains a significant challenge to realize time-dependent phosphorescence colors (TDPC) by embedding CDs with single emission center. In this study, we present a novel matrix-controlling strategy to regulate the microenvironment of CDs by doping limited Mn in zeolite. The surrounding environment influences the surface state of the CDs, leading to the formation of different excitons.

Thiourea-Driven Mild Synthesis of Photochromic Zeolite without H for Transient Information Storage.

The synthesis of hackmanite has been a topic of research for nearly 100 years, but up to now, the reported synthesis methods inevitably use reducing H to introduce the F-center through high-temperature calcination to make it change color, which extremely hinders its energy efficient large-scale synthesis before commercial applications. Herein, we present a facile route to synthesize hackmanite by using organic sulfur source thiourea as a precursor in a mild and hydrogen-free process. The synthesized hackmanite exhibits UVC-specific response, fast response, high contrast coloring, and fast fading at room temperature.

Bioactive polyketides and tryptophol alkaloids from the endophytic fungus Botryosphaeria dothidea LE-07 of Chinese tulip tree.

Two new tetraketide-derived phenol rhamnosides [botryrhamnosides A (1) and B (2)] and a new rhamnosylated tryptophol alkaloid (botryrhamnoside C, 3), along with seven related known compounds (4-10) were isolated from the solid culture of Botryosphaeria dothidea LE-07, an endophytic fungus residing in the leaves of the rare medicinal plant Chinese tulip tree (Liriodendron chinense).

Synergistic control potential of flue gas pollutants under Ultra-Low emission standards in waste incineration plants.

As the dominant waste disposal process, incineration is regarded as the main incentive for the "not-in-my-backyard" syndrome, and faces an inescapable pressures of ultra-low emissions (ULE). Establishing precise response relationships between emission factors (EFs) and full-process influencing factors can provide guidance for the synergistic mitigation of flue gas pollutants (FGPs). In this work, the multi-dimensional EFs of FGPs were identified by initially integrating FGPs concentration monitoring data of existing 1,226 processing lines in China, technologies applied and operational experience (OE), local economic and political characteristics.

3'-Deoxyadenosin alleviates methamphetamine-induced aberrant synaptic plasticity and seeking behavior by inhibiting the NLRP3 inflammasome.

JOURNAL/nrgr/04.03/01300535-202410000-00028/figure1/v/2024-02-06T055622Z/r/image-tiff Methamphetamine addiction is a brain disorder characterized by persistent drug-seeking behavior, which has been linked with aberrant synaptic plasticity. An increasing body of evidence suggests that aberrant synaptic plasticity is associated with the activation of the NOD-like receptor family pyrin domain containing-3 (NLRP3) inflammasome.

Time-Dependent and Excitation-Dependent Afterglow Color Evolution from the Assembly of Dual Carbon Dots in Zeolite.

Afterglow materials with time-dependent color output emerge as huge prospects in advanced optical information encryption but remain a formidable challenge due to the limited exciton transfer from a single emission center. Here, multiple time-dependent afterglow color evolutions are achieved by the strategy of controllable assembly of dual carbon dots (CDs) with an individual afterglow color and decay rate into an RHO zeolite. The strategy possesses high controllability such that B-CDs and G-CDs can be independently generated and in situ embedded into a matrix; in particular, the doped amount of two kinds of CDs can be adjusted conveniently to produce interesting variable afterglow colors.
