Light‐Harvesting Nanomaterials Based on Dyes for Energy Transfer and Amplified Biosensing

open access: yesAdvanced Materials, EarlyView.
Light harvesting (LH) in plants inspires researchers to develop artificial LH nanomaterials. Here, LH nanomaterials based on organic dyes are reviewed, considering fundamental challenges on aggregation‐caused quenching, excitation energy transfer, and exciton migration length.

Femtolitre Volume cryoEM Sample Preparation Using a Force‐Sensitive Microfluidic Cantilever

open access: yesAdvanced Materials Technologies, EarlyView.
Cryogenic electron microscopy enables structural imaging of biological molecules, but current methods lack targeted extraction of subcellular content for direct vitrification. This study introduces a force‐sensitive microfluidic cantilever pipette that aspirates and dispenses femtolitre volumes from individual cells onto electron microscopy grids.

Microwave‐Assisted One‐Pot Synthesis of Alkyl Levulinates From Post‐Harvest Vegetable Waste

open access: yesAdvanced Sustainable Systems, EarlyView.
Vegetable waste is valorized through Soxhlet extraction using H₂O₂ and heteropolyacid (HPA), followed by material characterization (XRD, FTIR, TGA, DSC). A microwave‐assisted reaction at 170 °C for 30 min with HPA and alcohol yields bio‐based esters.

Determinants of smokeless tobacco use in India

open access: yesThe Indian journal of medical research, 2018
Non-communicable diseases (NCDs) contributes to more than 50 per cent disability adjusted life years (DALYs) in India; and tobacco contributes to 7·4 per cent of DALYs which is next to diet and high blood pressure.

Insect‐Microbe‐Based Laccase: Untapped Natural Resource for Industrial and Biotechnological Applications

open access: yesAdvanced Sustainable Systems, EarlyView.
The insect‐microbe interplay fulfills a key ecological role involving the degradation of ligninocellulose biomass. This is coordinated by the secretion of different kinds of proteins, of which ligninolytic enzymes, such as laccases (Lacs), are of prime importance.
