Two novel tailored activated carbons (BC-41-OG and BC-41-MnN) with favorable physicochemical characteristics were successfully prepared for adsorption of dissolved natural organic matter (DOM) by applying systematically chemical and thermal treatment. This research was conducted to investigate the impact of the presence of phenolics on the adsorption capacity of DOM. Isotherm tests were performed for both humic acid (HA) and phenolics on both novel tailored activated carbons and commercial activated carbon F400. The presence of phenolics display a significant effect on hindering the adsorption of HA, however; the physicochemical characteristics of novel activated carbons (surface metal oxides and mesoporosity) can play an important role in alleviating this effect. In contrast, F400, with a relatively lower mesoporosity and surface basicity as compared to the developed adsorbents, was severely impacted by the oligomerization of phenolic compounds. The adsorption capacity of DOM in presence of phenolics was further studied in a continuous flow microcolumn system. The column results showed that both BC-41-OG and BC-41-MnN have not only higher HA adsorption capacity but also better selective adsorption ability than F400.

Rationale And Objectives: The precise prediction of response to neoadjuvant chemoradiotherapy is crucial for tailoring perioperative treatment in patients diagnosed with locally advanced rectal cancer (LARC). This retrospective study aims to develop and validate a model that integrates deep learning and sub-regional radiomics from MRI imaging to predict pathological complete response (pCR) in patients with LARC.
Materials And Methods: We retrospectively enrolled 768 eligible participants from three independent hospitals who had received neoadjuvant chemoradiotherapy followed by radical surgery.

Selenium deficiency associated with a high risk of many diseases remains a global challenge. Owing to the narrow margin between "nutrition-toxicity" doses of selenium, it is imperative to achieve accurate selenium supplement. Nano‑selenium (SeNPs) is a novel form of selenium supplement with low toxicity, but it could be trapped and removed by intestinal mucus, thus limiting its oral delivery.

Controlling vibrational modes and energy gap by creating van der Waals (vdW) heterostructures through strain engineering is a novel approach to tailor the vibrational and electronic properties of two-dimensional (2D) materials. Numerous theoretical and experimental studies have significantly contributed to analysing the properties of transition metal dichalcogenides (TMDs), known for their multifunctional applications. In this study, we investigate the strain and stacking dependent vibrational properties of WSe2/MoSe2 and MoSe2/WSe2/MoSe2 vdW heterostructures using first-principles based density functional theory calculations.

Accurate and rapid diagnosis of traumatic brain injury (TBI) is essential for high-quality medical services. Nonetheless, the current diagnostic platform still has challenges in rapidly and accurately analysing clinical samples. Here, we prepared a highly stable, repeatable and sensitive gold-plated silver core-shell nanowire (Ag@AuNWs) for surface-enhanced Raman spectroscopy (SERS) metabolic fingerprint diagnosis of TBI.

Heart failure (HF) poses a significant medical challenge, affecting millions of adults in the United States. High-output heart failure (HOHF) is a distinct subtype characterized by elevated cardiac output exceeding 8 L/min or a cardiac index >4 L/min/m². Patients with HOHF often present similarly to those with heart failure with reduced ejection fraction and heart failure with preserved ejection fraction.
