Advancing lithium-ion battery performance with heteroatom-based anode architectures for fast charging and high capacity.

Electric vehicles (EVs) are on the brink of revolutionizing transportation, but the current lithium-ion batteries (LIBs) used in them have significant limitations in terms of fast-charging capabilities and energy density. This feature article begins by examining the key challenges of using graphite for fast charging and silicon for achieving high energy density in LIBs. Firstly, it explores various design strategies employed by researchers worldwide to improve the fast-charging performance of graphite, such as surface coatings, morphological modifications, and binder design.

A 1-D model to retrieve the vertical profiles of minor atmospheric constituents for cloud microphysical modelling: III. Disturbed weather situations.

A hybrid Monte-Carlo Gear solver developed earlier has been improvised to retrieve the vertical profiles of CH and NO during disturbed weather situations such as western disturbances, tropical cyclones, and heavy rainfall events over the megacities: Delhi, Kolkata, Chennai, and Mumbai. Due to rapid changes in the temperature during the passage of these systems over megacities, the percentage differences of CH and NO number concentrations were more compared to the Community Long-term Infrared Microwave Coupled Atmospheric Product System (CLIMCAPS). Therefore, the hybrid solver has been modified by improving maximum likelihood estimates of vertical temperature profiles.

A 1-D model to retrieve the vertical profiles of minor atmospheric constituents for cloud microphysical modeling: II. Simulation of diurnal cycle.

The retrieved profiles of CH and SO have been tested with the Copernicus Atmosphere Monitoring Service (CAMS) model at 3-hour time intervals for four megacities: Delhi, Kolkata, Chennai, and Mumbai for rainy and non-rainy days.

A Soft-Bodied Aerial Robot for Collision Resilience and Contact-Reactive Perching.

Current aerial robots demonstrate limited interaction capabilities in unstructured environments when compared with their biological counterparts. Some examples include their inability to tolerate collisions and to successfully land or perch on objects of unknown shapes, sizes, and texture. Efforts to include compliance have introduced designs that incorporate external mechanical impact protection at the cost of reduced agility and flight time due to the added weight.

A 1-D model to retrieve the vertical profiles of minor atmospheric constituents for cloud microphysical modeling: I. Formulation and validation.

Determining the number concentration of minor constituents in the atmosphere is very important as it determines the whole tropospheric chemistry process. These constituents may act as cloud condensation nuclei (CCN) and ice nuclei (IN), impacting heterogeneous nucleation inside the cloud. However, the estimations of the number concentration of CCN/IN in cloud microphysical parameters are associated with uncertainties.

Indian College of Physicians (ICP) Position Statement on Pharmacovigilance.

Pharmacovigilance is the art and science of detection, understanding and prevention of adverse drug reactions and not merely a critical analysis of prescriptions and errors. This field starts with reporting by clinicians of a suspected adverse drug reaction (ADR) to the pharmacologist followed by joint causality analysis and ends at the application of new information by a clinician for benefit of patients. There are a number of ways, which can be utilised for reporting adverse effects using pen and paper format to software applications for smart phones.
