Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A Propensity Score Matched Analysis of Superparamagnetic Iron Oxide versus Radioisotope Sentinel Node Biopsy in Breast Cancer Patients after Neoadjuvant Chemotherapy [PDF]
Cancers, 2022 The standard method for nodal staging in breast cancer (BC) patients after neoadjuvant chemotherapy (NAC) is sentinel lymph node biopsy (SLNB) with a radioisotope (RI) injection. However, SLNB after NAC results in high false-negative rates (FNR), and the RI method is restricted by nuclear medicine unit dependency.

Isoelectronic Alloying in Zintl Phases Mediated the Avoided Crossing and Phonon Softening
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A small amount of Hf doping endows Zr3Ni3Sb4‐Zintl with an unusually low thermal conductivity far exceeding that of similar systems. Two unique phonon mechanisms—avoided crossing and phonon softening—significantly suppress the lattice thermal conductivity. The average thermoelectric figure of merit is improved by 21%.

2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions
Small, EarlyView.Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

2D Iron Oxide at the Graphene/SiC(0001) Interface
Small Methods, EarlyView.2D iron oxide was successfully formed via intercalation of Fe and O into the graphene/SiC(0001) interface. Atomic‐resolution electron microscopy revealed that the 2D iron oxide is encapsulated by graphene and sharply interfaced with SiC. This material is suggested to exhibit antiferromagnetic behavior at low temperatures.
