Ferroelectricity-controlled magnetic ordering and spin photocurrent in NiCl/GeS multiferroic heterostructures.

Controlling magnetism solely through electrical means is indeed a significant challenge, yet holds great potential for advancing information technology. Herein, our investigation presents a promising avenue for electrically manipulating magnetic ordering within 2D van der Waals NiCl/GeS heterostructures. These heterostructures, characterized by their unique magnetic-ferroelectric (FE) layer stacking, demonstrate spin-constrained photoelectric memory, enabling low-power electrical writing and non-destructive optical reading.

Regulating excitonic effects in non-oxide based XPSe (X = Cd, Zn) monolayers towards enhanced photocatalysis for overall water splitting.

The non-oxide 2D materials have garnered considerable interest due to their potential utilization as photocatalysts, which offer a superior substitute to metal-oxide-based photocatalysts. This study investigates the impact of the dielectric environment on the size and binding energy of excitons in atomically thin, experimentally synthesized semiconducting monolayers [XPSe, X = (Cd, Zn)] to address the critical problem of electron-hole recombination, which significantly hinders the efficiency of most photocatalysts. We employ a precise non-hydrogenic model surpassing the hydrogenic-based Mott-Wannier model.

Nanocatalytic Interface to Decode the Phytovolatile Language for Latent Crop Diagnosis in Future Farms.

Crop diseases cause the release of volatiles. Here, the use of an SnO-based chemoresistive sensor for early diagnosis has been attempted. Ionone is one of the signature volatiles released by the enzymatic and nonenzymatic cleavage of carotene at the latent stage of some biotic stresses.

Conflux of tunable Rashba effect and piezoelectricity in flexible magnesium monochalcogenide monolayers for next-generation spintronic devices.

The coupling of piezoelectric properties with Rashba spin-orbit coupling (SOC) has proven to be the limit breaker that paves the way for a self-powered spintronic device (ACS Nano, 2018, 12, 1811-1820). For further advancement in next-generation devices, a new class of buckled, hexagonal magnesium-based chalcogenide monolayers (MgX; X = S, Se, Te) have been predicted which are direct band gap semiconductors satisfying all the stability criteria. The MgTe monolayer shows a strong SOC with a Rashba constant of 0.

Lymph node metastasis of soft tissue tumors: a cytomorphologic study.

Objective: To study the frequency of regional lymph node metastasis of soft tissue tumors (STT) and to evaluate the utility of fine needle aspiration cytology (FNAC) as an initial investigative modality.

Study Design: A prospective and retrospective study of over 6 years (1998-2004) was performed to look for frequency of STT metastasizing to lymph nodes. FNAC of enlarged nodes was performed as a routine outpatient procedure after obtaining complete clinical details.
