Nanoscience and technology research offer exciting avenues to modernize undergraduate-level General Chemistry curricula. In particular, spherical nucleic acid (SNA) nanoconjugates, which behave as "programmable atom equivalents" (PAEs) in the context of colloidal crystals, are one system that one can use to reinforce foundational concepts in chemistry including matter and atoms, the Periodic Table, Lewis dot structures and the octet rule, valency and valence-shell electron-pair repulsion (VSEPR) theory, and Pauling's rules, ultimately leading to enriching discussions centered on materials chemistry and biochemistry with key implications in medicine, optics, catalysis, and other areas. These lessons connect historical and modern concepts in chemistry, relate course content to current professional and popular science topics, inspire critical and creative thinking, and spur some students to continue their science, technology, engineering, and mathematics (STEM) education and attain careers in STEM fields. Ultimately, and perhaps most importantly, these lessons may expand the pool of young students interested in chemistry by making connections to a broader group of contemporary concepts and technologies that impact their lives and enhance their view of the field. Herein, a way of teaching aspects of General Chemistry in the context of modern nanoscience concepts is introduced to instructors and curricula developers at research institutions, primarily undergraduate institutions, and community colleges worldwide.

Caseinolytic protease P (ClpP) is a highly conserved serine protease that plays a pivotal role in protein homeostasis and quality control in bacteria, mitochondria of mammalian cells, and plant chloroplasts. As the proteolytic core of the ATP-dependent Clp protease complex, ClpP partners with regulatory ATPases (e.g.

Papillary thyroid carcinoma (PTC) is the most prevalent form of thyroid cancer with a high incidence among endocrine malignancies. It tends to metastasize early in lymph nodes and differs markedly from other subtypes in biological behavior, clinical management, and prognosis. Therefore, accurately distinguishing PTC from other pathological subtypes is crucial for guiding diagnosis and treatment decisions.

Integration of ultrathin, high-quality gate insulators is critical to the success of two-dimensional (2D) semiconductor transistors in next-generation nanoelectronics. Here, we investigate the impact of atomic layer deposition (ALD) precursor choice on the nucleation and growth of insulators on monolayer MoS. Surveying a series of aluminum (AlO) precursors, we observe that increasing the length of the ligands reduces the nucleation delay of alumina on monolayer MoS, a phenomenon that we attribute to improved van der Waals dispersion interactions with the 2D material.

C-labeled α-amino acids are important molecules in biological studies and drug development. Cost-effective synthesis of α-amino acids with a high level of C incorporation under mild conditions remains limited. Herein, we report the development of a benzylic C(sp)-H carboxylation method to prepare highly C-labeled α-amino acids, i.

Ultrathin amorphous materials are promising counterparts to 2D crystalline materials, yet their properties and functionalities remain poorly understood. Amorphous boron nitride (aBN) has attracted attention for its ultralow dielectric constant and superior manufacturability compared with hexagonal boron nitride. Here, we demonstrate wafer-scale growth of ultrathin aBN films with exceptional thickness and composition uniformity using capacitively coupled plasma-chemical vapor deposition (CCP-CVD) at 400 °C.
