Pick-and-Place Transfer of Arbitrary-Metal Electrodes for van der Waals Device Fabrication.

Van der Waals electrode integration is a promising strategy to create nearly perfect interfaces between metals and 2D materials, with advantages such as eliminating Fermi-level pinning and reducing contact resistance. However, the lack of a simple, generalizable pick-and-place transfer technology has greatly hampered the wide use of this technique. We demonstrate the pick-and-place transfer of prefabricated electrodes from reusable polished hydrogenated diamond substrates without the use of any sacrificial layers due to the inherent low-energy and dangling-bond-free nature of the hydrogenated diamond surface.

Choline Oxidase-Incorporated ATRP-Based Cerium Nanogels as Nanozymes for Colorimetric Detection of Hydrogen Peroxide and Choline.

Choline is an important molecule in monitoring food safety and infant nutrition. Here, we report Ce nanogels synthesized by atom transfer radical polymerization (ATRP) employing Ce-coordinated acryloyl-lysine polymer brushes (Ce@SiO NGs) as highly efficient cascade nanozymes for colorimetric detection of choline. The synthesized Ce@SiO NGs demonstrated remarkable peroxidase-like activity with a porous exterior, which are essential to entrap choline oxidase (COx) to yield COx@Ce@SiO NGs and construct a cascade reaction system to detect choline.

Activating SERS Signals of Inactive Analytes: Creating an Energy Bridge between Metal/Molecule Energy Alignment via Metal/Semiconductor Transitions.

Surface-enhanced Raman spectroscopy (SERS) is a powerful analytical technique, yet it faces challenges with certain probe molecules exhibiting weak or inactive signals, limiting their applicability. In a recent study, we investigated this phenomenon using a set of four probe molecules─chloramphenicol (CAP), 4-nitrophenol (4-NP), amoxicillin (AMX), and furazolidone (FZD)─deposited on Ag-based nanostructured SERS substrates. Despite being measured under identical conditions, CAP and 4-NP exhibited SERS activity, while AMX and FZD did not.

Predicting early stage lung cancer recurrence and survival from combined tumor motion amplitude and radiomics on free-breathing 4D-CT.

Background: Cancer control outcomes of lung cancer are hypothesized to be affected by several confounding factors, including tumor heterogeneity and patient history, which have been hypothesized to mitigate the dose delivery effectiveness when treated with radiation therapy. Providing an accurate predictive model to identify patients at risk would enable tailored follow-up strategies during treatment.

Purpose: Our goal is to demonstrate the added prognostic value of including tumor displacement amplitude in a predictive model that combines clinical features and computed tomography (CT) radiomics for 2-year recurrence and survival in non-small-cell lung cancer (NSCLC) patients treated with curative-intent stereotactic body radiation therapy.

Climate change policies reduce air pollution and increase physical activity: Benefits, costs, inequalities, and indoor exposures.

The burden of diseases attributable to air pollution is comparable to those of global health risks such as unhealthy diets and tobacco smoking, with many air pollution sources also emitting climate heating gases.

Photochemical and Collision-Induced Cross-Linking of Lys, Arg, and His to Nitrile Imines in Peptide Conjugate Ions in the Gas Phase.

We report a study of internal covalent cross-linking with photolytically generated diarylnitrile imines of N-terminal arginine, lysine, and histidine residues in peptide conjugates. Conjugates in which a 4-(2-phenyltetrazol-5-yl)benzoyl group was attached to C-terminal lysine, that we call RAAA--K, KAAA--K, and HAAA--K, were ionized by electrospray and subjected to UV photodissociation (UVPD) at 213 nm. UVPD triggered loss of N and proceeded by covalent cross-linking to nitrile imine intermediates that involved the side chains of N-terminal arginine, lysine, and histidine, as well as the peptide amide groups.

Prospective Evaluation of Ureteral Wall Thickness as a Means to Predict Spontaneous Stone Passage: Is It Beneficial?

Ureteral wall thickness (UWT) was proposed as a potential predictor for spontaneous stone passage (SSP). In earlier studies, the effect could not be isolated from stone size. Accordingly, we sought to determine whether UWT, alone or combined with stone size, could enhance SSP predictability.

Patient-specific mapping of fundus photographs to three-dimensional ocular imaging.

Background: Ocular proton beam therapy (OPT) planning would benefit from an accurate incorporation of fundus photographs, as various intra-ocular structures, such as the fovea, are not visible on conventional modalities such as Magnetic Resonance Imaging (MRI). However, the use of fundus photographs in OPT is limited, as the eye's optics induce a nonuniform patient-specific deformation to the images.

Purpose: To develop a method to accurately map fundus photographs to three-dimensional images.
