Optical imaging and phototherapy in deep tissues face notable challenges due to light scattering. We use encoded acoustic holograms generate three-dimensional fields within the target medium, enabling instantaneous robust modulation of volumetric refractive index, thereby noninvasively controlling trajectory light. Through this approach, we achieved a remarkable 24.3% increase tissue heating rate vitro photothermal effect tests on porcine skin. In vivo photoacoustic mouse brain vasculature...
High precision neuromodulation is a powerful tool to decipher neurocircuits and treat neurological diseases. Current non-invasive methods offer limited at the millimeter level. Here, we report optically-generated focused ultrasound (OFUS) for brain stimulation with ultrahigh precision. OFUS generated by soft optoacoustic pad (SOAP) fabricated through embedding candle soot nanoparticles in curved polydimethylsiloxane film. SOAP generates transcranial focus 15 MHz an lateral resolution of 83...
Quercetin (Que) has been proven to enhance the chemosensitivity of multiple cancers, including colon cancer (CC). However, whether combination Que and 5-fluorouracil (5-FU) a synergistic effect on drug-resistant CC cells not previously reported. The (5 10 μg/mL) cell vitality apoptosis was examined using counting kit-8 (CCK-8) flow cytometry. After were treated with 5-FU (10, 40 μg/mL), (10 μM, μM), or in Que, proliferation, apoptosis, oxidative stress-related factors, reactive oxygen...
High-resolution, sub-MHz-bandwidth data converters are essential for audio and sensor applications conventionally implemented as sigma-delta (SD) converters. The dependence of SD ADCs on op-amps inherently results in difficulties process scaling, power efficiency improvement, area reduction. A promising alternative to is the emerging noise-shaping (NS) SAR ADC, which provides high resolution with energy compactness. For medium-high SNR applications, some NS-SAR already exhibit better...
Highly precise neuromodulation with a high efficacy poses great importance in neuroscience. Here we developed candle soot fiber optoacoustic emitter (CSFOE), capable of generating pressure over 10 MPa central frequency 12.8 MHz, enabling highly efficient vitro. The design the emitter, including choice material and thickness layered structure, was optimized both simulations experiments. conversion efficiency CSFOE found to be times higher than other carbon-based emitters. Driven by single...
In hydrothermal valorization of black liquor (BL) from the Kraft process, separation inorganic salts is pivotal to prevent them fouling downstream equipment such as reactors and for cost-efficient recycling into pulp cooking chemicals. this work, phase behavior present in BL was studied supercritical water conditions were optimized. A high-pressure differential scanning calorimetry study indicated concomitant precipitation formation a second salt-rich liquid-like phase. The...
Conversion of coal, biomass, and organic waste to combustible gases H2 CH4 in supercritical water (SCW) is an economically environmentally favored technology. Homogeneous alkaline catalysts are commonly added achieve high conversion efficiency, as alkalis believed accelerate the gasification aromatic structures, which bottleneck whole process. Nevertheless, mechanism how alkali metals influence reaction structures still not acknowledged clearly. In this work, different pretreatments...
This work extends the bandwidth and frequency range of digital-phase-shifting direct-digital-to-RF TX, paving way for use in MU-MIMO wireless networking applications. A sigma-delta modulation chain enables an inherently linear 1b RF DAC. Low-loss FIR filtering suppresses DAC noise. An H-bridge combines current-DAC, FIR-filtering up-conversion efficiency. 28 nm CMOS 8-element 6 GHz beamforming TX has a per-element area 0.01 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Reliable packaging for implantable neural prosthetic devices in body fluids is a long-standing challenge devices' chronic applications. This work studied the stability of Parylene C (PA), SiO2, and Si3N4 packages coating strategies on tungsten wires using accelerated, reactive aging tests three solutions: pH 7.4 phosphate-buffered saline (PBS), PBS + 30 mM H2O2, 150 H2O2. Different combinations thicknesses deposition methods were at various testing temperatures. Analysis preliminary data...
Tunable 2∼3-μm femtosecond lasers are of high interest in various applications, such as medical diagnostics and molecular spectroscopy. Cr:ZnSe/ZnS is extremely suited for broadband tunable due to its excellent emission bands. In this article, we demonstrate a wavelength-tunable Kerr-lens mode-locked Cr:ZnS laser by utilizing birefringent filter. The group delay dispersion the operation thickness finely optimized. With rotation filter, scheme offers tuning bandwidth over 300 nm from 2,220...

Oligosaccharides are important functional active components of Lycium barbarum L. (LBL, "Goji") fruits, but their metabolic mechanisms not yet clear. In this study, we firstly investigated the changes in content oligosaccharides LBL at different stages (S1–S5), and found that it mainly accumulated S3 S4. Secondly, structural characteristics oligosaccharide (LBO) were studied by GC-MS FT-IR. Thirdly, using iTRAQ proteomics analysis, identified 135 differentially expressed proteins associated...
