O primeiro ano-agrícola após o plano real

open access: yes, 1995
O setor agrícola foi um dos primeiros a sentir os pesados custos causados pela combinação de políticas macroeconômicas do Piano Real, isto é, política monetária apertada e valorização da taxa de câmbio. O primeiro semestre de 1995 foi um dos mais dificeis dos ultimos vinte anos.

Selenium biofortification: integrating one health and sustainability

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 1955-1967, 15 March 2026.
Abstract Selenium (Se) biofortification in crops has emerged as a promising strategy to address global Se deficiencies and enhance both agricultural productivity and human health. Increasing the Se content of crops through biofortification improves their resilience to abiotic and biotic stresses and boosts their nutritional value.

Colloidal Crack Sintering Lithography for Light‐Induced Patterning of Particle Assemblies

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Colloidal crack sintering lithography (CCSL) is a microfabrication technique that uses light‐induced photothermal heating to trigger sintering and controlled cracking in polymer colloidal assemblies. Local structural changes generate microchannels and patterns, enabling direct writing of diverse topographic motifs.

Spatiotemporal Plasma–Mediated Laser Fabrication of Ultrahigh‐Aspect‐Ratio Nanochannel Arrays for Vertical Perovskite Nanowire Semiconductor Devices

open access: yesAdvanced Functional Materials, Volume 36, Issue 23, 19 March 2026.
A spatiotemporal plasma–mediated laser processing approach is developed to fabricate ultrahigh–aspect ratio nanochannel arrays and corresponding perovskite nanowire arrays within transparent materials for optoelectronics devices. The laser‐fabricated nanochannels serve as templates for controlled perovskite infiltration and crystallization, enabling ...

Label‐Free Detection of PSA Using Laser‐Induced Graphene/ZnO Nanorod‐Based Impedimetric Immunosensors

open access: yesAdvanced Sensor Research, Volume 5, Issue 3, March 2026.
A label‐free impedimetric immunosensor based on laser‐induced graphene decorated with ZnO nanorods is developed for prostate‐specific antigen detection. Antibody adsorption on ZnO enables clinically relevant sensitivity and an unconventional “signaling‐off” response, where charge‐transfer resistance decreases upon antigen binding, challenging ...
