We present a transcriptomics pipeline for performing the functional analysis of array expression profiling data of normal and adenocarcinoma lung tissue. Our aims are twofold, firstly to elucidate molecular processes that transform normal tissue, to a lung adenocarcinoma. Following this, we perform functional analysis to screen potential hub genes and demonstrate their value in cancer prognosis. Analysis was performed on a total of 500 differentially expressed genes (DEG), screened for their regulation and transcriptional modulation in a female population carrying non–small cell lung carcinoma (NSCLC). Key pathways like cytokine-cytokine receptors, ECM receptor interactions, and TNF signaling were identified suggesting a potential role in lung tumorigenesis. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Refractory compositionally complex alloy (RCCA) NbMoTaW with a well-dispersed compositionally complex carbide (CCC) reinforcing secondary phase is made through high-energy ball milling (HEBM) and ultrafast high-temperature sintering (UHS). Stearic acid is used as a process control agent (PCA) for HEBM and a carbon source to form a controllable fraction (~2-20 vol%) of CCC in-situ via reactive synthesis. Ultrahigh heating rates of ~100 °C/s enable sintering of dense (~93-97 % relative densities) bulk compacts of RCCA-CCA composites at ~1850 °C in ~70 seconds. With the addition of 0.1-0.75 wt% PCA, ultrafast sintering enables the formation of a favorable P m1 subcarbide CCC phase, (Nb0.37Mo0.11Ta0.39W0.13)2C. A thermodynamic model is developed to explain the observed Nb and Ta enrichments in (Nb0.37Mo0.11Ta0.39W0.13)2C. An additional rock-salt monocarbide CCC phase forms with more carbon source addition (1 wt% PCA). The well-dispersed and fine-grained CCC precipitates result in grain size refinement and a corresponding increase in hardness. © 2025, The Authors. All rights reserved.

This study proposed country-specific characterisation factors (CFs) for Thailand by modifying the Thai Spatially Differentiated Life Cycle Impact Assessment (ThaiSD) method and introducing monetary conversion factors to express environmental impacts in Thai Baht. Five impact categories were fully parameterised, including fine particulate matter formation (PMF), human toxicity (both cancer and non-cancer) (HT c and HT nc ), freshwater ecotoxicity (FET), and water scarcity (WS). Other spatialised CFs were selected from regionalisation models in ReCiPe2016 and IMPACT World+. When comparing the use of country-specific CFs with global average, the impact scores for PMF, HT c , HT nc , FET, photochemical ozone formation and terrestrial acidification demonstrated notably different levels, ranging from ±25 to ±50 %. The developed method was then applied to assess environmental impacts and costs of Thailand's transport sector, encompassing freight and passenger transport across roadway, railway, waterway, and aviation. Climate change (CC) was significantly attributed to human health and ecosystem quality impacts, while the major contributor to resource scarcity impact was fossil resource scarcity (FS). In some scenarios, non-exhaust emissions, particularly from freight trucks, accounted for 40–60 % of the total PMF impacts. Environmental costs of freight and passenger transport in Thailand were 0.08–3.64 Thai Baht per tonne-kilometre and 0.01–0.81 Thai Baht per passenger-kilometre, respectively. Among transport modes, trains were found to be the most environmentally favourable option for both passenger and freight transport, while aviation had the highest environmental impact for freight transport. In contrast, passenger aviation had a comparable environmental burden to passenger cars due to optimised occupancy rates. Despite the efficiency of modern internal combustion engine vehicles (ICEVs), particularly Euro 5 and 6, employing blended biodiesel was less effective in comp

Co60Fe20Sm20 thin films were deposited onto glass substrates in a high vacuum setting. The films varied in thickness from 10 to 50 nm and underwent annealing processes at different temperatures: room temperature (RT), 100, 200, and 300 °C. Our analysis encompassed structural, magnetic, electrical, nanomechanical, adhesive, and optical properties in relation to film thickness and annealing temperature. X-ray diffraction (XRD) analysis did not reveal characteristic peaks in Co60Fe20Sm20 thin films due to insufficient growth-driving forces. Electrical measurements indicated reduced resistivity and sheet resistance with increasing film thickness and higher annealing temperatures, owing to hindered current-carrier transport resulting from the amorphous structure. Atomic force microscope (AFM) analysis showed a decrease in surface roughness with increased thickness and annealing temperature. The low-frequency alternating current magnetic susceptibility (χac) values increased with film thickness and annealing temperature. Nanoindentation analysis demonstrated reduced film hardness and Young’s modulus with thicker films. Contact angle measurements suggested a hydrophilic film. Surface energy increased with greater film thickness, particularly in annealed films, indicating a decrease in contact angle contributing to this increase. Transmittance measurements have revealed intensified absorption and reduced transmittance with thicker films. In summary, the surface roughness of CoFeSm films at different annealing temperatures significantly influenced their magnetic, electrical, adhesive, and optical properties. A smoother surface reduced the pinning effect on the domain walls, enhancing the χac value. Additionally, diminished surface roughness led to a lower contact angle and higher surface energy. Additionally, smoother surfaces exhibited higher carrier conductivity, resulting in reduced electrical resistance. The optical transparency decreased due to the smoother surface of C

The utilization of femtosecond laser pulses in synthesizing silicon nanocrystals (SiNCs) poses great potential in producing stable nanostructures with chemically pure surfaces and easy-to- manipulate optical properties. In this work, we present an approach that enhances the production and optical quality of surfactant-free SiNCs synthesized in water by ablating silicon wafer with ytterbium fiber femtosecond laser operating at different pulse energies and repetition rates. By further post-synthesis laser treatment of SiNCs suspensions, fragmentation of larger aggregates is observed leading to absorption broadening and absorption-band blueshift. Furthermore, the increase in the repetition rate, from 1 to 500 kHz, of laser pulses having energies of 20 and 240 mJ leads to a decrease in the Si wafer ablation efficiency from 35 to 1.15 pg/pulse;and from 440 to 5.2 pg/pulse, respectively. Using laser pulses with energy of 240 mJ and a repetition rate of 50 kHz results in maximum SiNCs productivity of 33 mg/h. The dependence of the nanostructures’s size and ablation efficiency on the pulse energy and repetition rate is attributed to thermal effects on the Si/water interface and within the water layer illuminated by the strong laser radiation. © 2023, The Authors.

Rectifier plays a pivotal role in wireless power transfer systems. While numerous studies have concentrated on enhancing efficiency and bandwidth at specific high-power levels, practical scenarios often involve unpredictable power inputs. Consequently, a distinct need arises for a rectifier that demonstrates superior efficiency across a broad range of input power levels. This paper introduces a high-power RF-to-DC rectifier designed for WPT applications, featuring an ultrawide dynamic range of input power. The rectification process leverages a GaN (gallium nitride) high electron mobility transistor (HEMT) to efficiently handle high power levels up to 12.6 W. The matching circuit was designed to ensure that the rectifier will operate in class-F mode. A Schottky diode is incorporated into the design for relatively lower-power rectification. Seamless switching between the rectification modes of the two circuits is accomplished through the integration of a circulator. The proposed rectifier exhibits a 27.5 dB dynamic range, achieving an efficiency exceeding 55% at 2.4 GHz. Substantial improvement in power handling and dynamic range over traditional rectifiers is demonstrated. © 2024 by the authors.

The integration of organic bioelectronic interfaces has opened new avenues for merging biological systems with electronics, offering transformative solutions to challenges in both fields. In this study, we present a novel hybrid organic electrochemical transistor (OECT) featuring self-assembled three-dimensional (3D) nanofiber arrays (NFAs) of small-molecule semiconductors grown on poly(3,4-ethylenedioxythiophene):polystyrenesulfonate active-layer channels. The hybrid OECT was further evaluated for its potential to capture, recover, and biosense circulating tumor cells (CTCs), as well as to enhance extracellular vesicle (EV) secretion through electrical stimulation (ES). Using template-free self-assembly via standard thermal evaporation, out-of-plane coronene (CR)-based NFAs were fabricated and surface-engineered with 1-pyrenebutyric acid through π-π interactions, enabling bioaffinity coatings on OECTs for advanced biological applications. The device demonstrated efficient CTC isolation, achieving an isolation rate exceeding 90% for MCF-7 breast cancer cells spiked into THP-1 monocytic cells (10 cells mL), with minimal nonspecific binding by incorporating a specific antibody-coated CR-based NFA layer. Moreover, over 80% of the captured CTCs were released from CR-based NFAs during cyclic voltammetry sweeps in phosphate-buffered saline. The device also enhanced EV secretion by incorporating a collagen-coated CR-based NFA layer, which supported cell attachment and proliferation under sustained ES at 20 V, 0.5 Hz, with 5 ms pulses for 24-72 h periods. EV production increased by approximately 12.4-fold in MCF-7 cells and 8.0-fold in immortalized bone marrow stromal cells without significantly altering the EV size or requiring additional cellular modifications. This dual-functionality platform, enabled by a surface-engineered 3D-hybrid OECT, is a powerful tool for selective CTC isolation, liquid biopsy purification, and enhanced EV production. This versatility highlights
